Case White (German: Fall Weiss), also known as the Fourth Enemy Offensive (Serbo-Croatian: Četvrta neprijateljska ofenziva/ofanziva) was a combined Axis strategic offensive launched against the Yugoslav Partisans throughout occupied Yugoslavia during World War II. It was one of the most significant confrontations of World War II in Yugoslavia. The offensive took place in early 1943, between 20 January and mid-to-late March 1943. The Axis operation prompted the Partisan Supreme Command to put in motion its plans for the drive toward the eastern Herzegovina, Sandžak and Montenegro. In order to do this, Tito formed the so-called Main Operational Group, which eventually succeeded in forcing its way across the Neretva in mid-March 1943, after a series of dramatic battles with various hostile formations. Other Partisan formations, the 1st Croatian and 1st Bosnian Corps, managed to evade Axis blows and, despite significant losses, reclaim most of the territory they had held before the beginning of the operation.
Since its final stage took place on the Neretva River, the operation was known in Yugoslavia as the Battle of the Neretva (Bitka na Neretvi). This stage is also known as the Battle for the Wounded (Bitka za ranjenike).

In late 1942, with the Axis situation in North Africa deteriorating, the German high command became concerned about the possibility of an Allied landing in the Balkans. In the event of an Allied landing, resistance forces in Yugoslavia would be likely to interfere with German defensive operations as well as economic exploitation of natural resources, including timber, copper and bauxite. As a result, on 16 December 1942, Adolf Hitler ordered the Armed Forces Commander in South-East Europe, Generaloberst Alexander Löhr to crush the resistance in Yugoslavia. In a meeting of 18–19 December, the General Staff of the Wehrmacht decided on the destruction of the Bihać Republic. On 8 January, Löhr and Mario Roatta, commander of the 2nd Italian army, met in Zagreb and devised a detailed plan.
The operation was planned to be carried out in three stages:
- Weiss 1 aimed at destroying Partisan-held areas: Lika, Kordun, Banija, Cazinska Krajina, and Grmeč. It was started on 20 January 1943 and lasted until 25 February.
- Weiss 2 focused on Partisans in the south-east of the Bihać Republic: Drvar, Glamoč, Livno, Jajce, and Ključ.
- Weiss 3 was meant to be executed in Eastern Herzegovina and Montenegro, targeting mostly the Royalist Chetniks. This phase was cancelled in early February 1943.
The Germans aimed to destroy the central command of the Partisan movement, the Central Committee of Communist Party of Yugoslavia, as well as the bulk of the Partisan units around the Supreme HQ. The Axis mustered ten divisions equaling 90,000 troops and some twelve air squadrons.
Chetnik auxiliaries and formations consisting of between 12,000 and 15,000 men also took part and worked closely with the Italians. The operation coincided with the so-called "March on Bosnia", a plan which called for concentration of Chetniks from Lika, northern Bosnia, northern Dalmatia, Herzegovina, and Montenegro in order to destroy the Partisan-held territory there. "March on Bosnia" also the plan for “ethnic cleansing” of Muslim population in Bosnia and Herzegovina and in Sandžak. According to the Germans, the Chetniks stood at 150,000 men in February 1943 (up from 100,000 in August 1942). The Partisans on the other hand numbered less than a third of that figure. On 2 January, Mihailović reported to the Chetniks of his plan for the destruction of the Partsian's Bihać Republic in order to "liberate this Serb territory from Communist terror". On the 21st he wrote: "Indeed, the question of Bosnia is most important. In western Bosnia and Lika we are currently making the final preparations for the definitive destruction of the Communists who are preventing us from destroying Pavelić's Croatia"."
The orders for the operation required extreme severity towards captured Partisan and civilian population. The former were to be shot after capture, and civilian population deemed hostile was to be deported to transit camp. Villages in the combat area were to be razed to the ground. The commanders on the ground were prohibited from persecuting their subordinates for excessive harshness.
According to the plan, four German divisions (7th SS, 369th, 714th and 717th) were to attack from the arch stretching from Karlovac across Glina, Kostajnica, Bosanski Novi, Sanski Most towards the line Bihać - Petrovac. Three Italian divisions ("Lombardia", "Re" and "Sassari") were to advance on their right wing, through Lika and northern Dalmatia. According to the plan, the 7th SS and 717th Divisions, deployed on the extreme ends of the arch, were to race into the enemy rear with motorized battle-groups and meet at Vrtoče on the second day of the operation. The reinforced 369th and 714th Division were to meet them and close the circle around the bulk of the Partisan forces in the area of the mountain Grmeč. In the final stage, three divisions were supposed to destroy the encircled Partisans, and to deport the population to prevent the possibility of the revival of guerrilla activity in the area.
German divisions were reinforced with the 202nd tank battalion, and 2nd and 3rd Home Guard Mountain Brigade. Italian divisions used the Lika, Dalmatia and Herzegovina Chetnik auxiliaries, and three (31st, 32nd and 34th) Ustasha and one (2nd Jäger) Home Guard battalions. On 8 January 2 and 5 Krajina Brigade moved to Kozara and launched a series of attacks on the NDH garrisons and posts in Lijevče polje. Since these activities coincided with the attacks of the 1st Proletarian Division in central Bosnia, General Lüters decided to exclude the 714 division from the operation Weiss, and to use it for the defense of the Banja Luka area. As the 718th Division was already engaged in fighting the Partisans in central and eastern Bosnia, Lüters reinforced the 369th Division with one regimental combat group of the 187th Reserve Division.
The attack from the all directions began on 20 January, but none of the divisions succeeded in keeping up with the original schedule. The Axis forces attacked the territory controlled by the Partisan 1st Croatian and 1st Bosnian Corps – the areas of Banija, Kordun, Lika and western Bosnia. On the Karlovac - Bihać axis, four Partisan brigades were defending against the attack of the 7th SS division: 4th and 15th Brigade of the 8th Kordun Division, and 6th and 14th Littoral-Gorski Kotar Brigades. The 7th Banija Division was successful in containing the advance of the 369th Division from Glina and Kostajnica towards Cazin and Bosanska Krupa. The 6th Lika Division successfully held the line Plitvička Jezera - Gračac against the Italian attacks.
The 717th Division encountered great difficulties while trying to reach Bosanski Petrovac from Sanski Most. The Division launched the attack on 20 January with its 749 Regiment and elements of the 202nd Tank Battalion. Despite air support, it was halted by the 1st Krajina and one battalion of 7th Krajina Brigade some 10 km south from Sanski Most. The division’s 737th Regiment was in reserve, standing ready to exploit the breakthrough, but the 749th Regiment failed to make one. In following days both sides stepped up the efforts, building up strength in the key point, but the Partisans remained successful in blocking German attacks, while launching fierce night counter-attacks. The 717th Division tried with diversionary attack from Sanski Most westwards with the 2nd Mountain Home Guard Brigade. On 25 January this battle group of 2 Home Guard battalions and one German company were counter-attacked by the 1st Battalion of the 6th and the 3rd Battalion of the 1st Krajina Brigade, and it was routed with heavy losses. The booty included 40 light and 10 heavy machine guns, 4 mountain and 1 anti-tank cannon. General Dipold, Commander of the 717th division reported to General Lüters that on 26 January 2nd Home Guard Brigade was completely shattered, and that the remnants of the 2nd and 4th battalion were absorbed into 749th Grenadier Regiment. The more ambitious attack in the western direction was launched on 27 January with the reinforced 737th Regiment. The Regiment had succeeded to reach Benakovac before being halted by the 6th Krajina Brigade. In the meantime, the 2nd and 5th Krajina Brigade arrived from Kozara as reinforcements, and the 737th Regiment suddenly found itself in a difficult situation. Seeing no alternative, the regiment set up an all round defence; it remained cut off and under attacks until 3 February.
Simultaneously, 717th Division resumed the attack on the main axis towards Ključ and Bosanski Petrovac. The attack was scheduled to begin in the early hours of 28 January, but battalions of the 1st Krajina Brigade succeeded to surprise the Germans during the night with the preventive attack at their starting-off positions and to scatter their units. On the next day, the Germans launched an attack led by tanks with the intention of collecting weapons and stragglers, but the Partisan anti-tank fire destroyed the first tank, killing the commander of the 202nd Tank Battalion, lieutenant colonel von Geyso.
Attack on Grmeč
The Partisan defense line, which withstood most of German attacks so far, was finally compromised by the advance of the 7th SS Division. This unit, with some help of the two Italian divisions on the right flank, was steadily pushing back four Partisan Brigades, capturing Slunj on 24, and Rakovica on 27 January. As a result, Bihać came under threat and had to be evacuated, and Germans entered it on 29 January without a fight. turn of events also compromised the positions of the 7th Partisan Division in the Banija region. The 7th Division was ordered to withdraw and occupy a new line in front of the 7th SS Division, covering the axis Bihać - Petrovac. Thousands of refugees left Banija together with the Partisan units, suffering air-attacks, hunger, frost and diseases along the way.
The 7th SS division continued to push towards Petrovac, against Partisan defenses consisting mainly of the 7th Banija Division. It took another 10 days to cover these 50 kilometers. The 7 SS Division reached Petrovac on 7 February, and on 9 February finally managed to link-up with the 717th Division, thereby fulfilling the task originally scheduled for the second day of the operation. The 369th Division and the 3rd Home Guard Mountain Brigade, facing only Partisan rearguards, reached Bosanska Krupa on 30 January and relieved the encircled 737th Regiment at Benakovac on 3 February. One day later, the 369th joined hands with the 7th SS near Bihać. With this, the broader area of Grmeč was encircled by three German divisions. On 6 February, after they had received reinforcements, the 369th, 187th and 717th Division started their attack on Grmeč. 2nd and 5th Krajina Brigade were caught in the encirclement, along with some 15,000 inhabitants. On 10 February, the brigades made the decision to break out of the encirclement, and succeeded in opening the way over the road Krupa - Sanski Most toward Potkalinje. The inhabitants followed the brigades, but large number (up to 2.000) succumbed to freezing weather. Some 400 remaining civilians were killed by the Germans.
According to a German report from 18 February for the Weiss 1, 7th SS Division suffered losses of 149 dead, 222 wounded and 68 missing, and the 717th Division 118 dead, 290 wounded and 20 missing. The same report puts the Partisan losses at 6,561 dead, but adds that only 286 rifles were captured. This drastic imbalance between the figures suggests that the killed were mainly civilians.
During the first half of 1942 the Partisans were expelled from the eastern parts of Yugoslavia, and Axis powers largely succeeded in pacifying these areas. The Partisans established a stronghold in the western parts of the country, but the return to the east remained one of the main Partisan objectives. Localization of the guerrilla activity enabled the Germans to leave the control of pacified areas to second grade forces, and to concentrate their best units in on the endangered areas. The 714th, 717th and 7th SS Divisions (all in west Bosnia in January 1943) were all originally deployed in Serbia. Tito started with the plans for a march to the east in the early autumn of 1942. The original idea was to start the large movement in the spring, but the signs of the imminent Axis offensive in the January 1943 made Tito order the commencement of the operations without any delay.
The operation was to be carried out in three stages: the first stage was advance to Neretva, the second advance from Neretva to Drina, and the third from Drina to Lim, and further to the south-east. The main intention was to revive the Partisan presence and activities in these areas. On 8 February in Tomislavgrad, Tito presented the plan for the first stage on the conference with the staffs of the 1st, 2nd nad 3rd Division, and issued the necessary orders and directives.
The execution of the offensive was facilitated with the fact that the main forces Tito was counting on for the operation(1st and 2nd Proletarian and 3rd Shock Division) were deployed outside the area affected by the operation Weiss 1. The most distant unit, 1st Proletarian Division, was ordered to begin preparing for a start-off march in late January. The main Partisan force was divided into three columns:
- Right Column (2nd Proletarian Division) was to advance over Imotski, Posušje and Drežnica with the aim of cutting off communications in Neretva valley, and protecting the right flank of the Partisan main force against enemy garrison at Mostar.
- Central Column (3rd Shock Division) had the most difficult task: to capture Gornji Vakuf, Prozor, Ostrožac on Neretva and Konjic, and to open the way across the Neretva at Konjic.
- Left Column (1st Proletarian Division) was ordered to advance over Gornji Vakuf, Solakova Kula, Bradina and Ivan sedlo, protecting the right flank of the Partisan main force against enemy garrison at Mostar, destroy all traffic installations between Konjic and Sarajevo, and to provide protection for the Partisan northern flank against possible enemy intervention from Sarajevo by securing the main mountain pass of Ivan sedlo.
7th Banija Division was tasked with acting as the group’s rearguard and protecting the recently formed “Central Hospital” with some 4,000 sick and wounded. The hospital was created in order to provide protection to the wounded, since they were routinely targeted for execution by the Axis. The existence of the “Central Hospital” had a profound impact on the course and outcome of the forthcoming operations.
The Right Column (2nd Proletarian Division) started its advance with easy victories over NDH garrisons in Posušje and Imotski on 9 and 10 February. On 15 February, it reached Neretva, and attacked small Italian garrison in Drežinca. The 1st Battalion of the 260th Regiment of the Division Division Murge intervened from Mostar, but was almost completely annihilated (120 dead and 286 captured, including the Commander, lieutenant colonel Francesco Metella), on 16 February with the loss of all its equipment. The Partisans sent a messenger to Mostar with the proposition for the prisoner exchange, but the exchange did not happen.
With this success, the 2nd Division wrestled the control over the Neretva valley north of Mostar, and severed all contact between the city and Italian garrisons to the north. The Italian Command concluded that the Mostar garrison was endangered, and decided to mobilize immediately all available Chetnik units. Originally, the Italians had agreed not to use the Chetniks from Montenegro on the territory of the NDH, but now had to reverse their decision in face of the looming threat to their interests in Herzegovina.
The 2nd Proletarian Division, for its part, felt confident with its new position. As it had fulfilled its main task, the Division sent its 4th Proletarian Brigade to the north in order to assist the Central Column.
In the opening phase, the Central Column (3rd Division), captured Gornji Vakuf on 30 January, and by 8 February was making preparations for an attack on the Prozor garrison. Prozor was defended by the 3rd Battalion of the Italian 259th Regiment, reinforced with some infantry and artillery units, along with a company of light tanks L3. The town was heavily fortified with a large number of stone and concrete bunkers surrounded by wire obstacles and covered by a well-organized fire system. The Partisan attack began on the evening of 15 February, but failed due to fierce resistance of the garrison.
After receiving reinforcements, the 3rd Division gave it another try and the second attack had ultimately succeeded. The Italian garrison was destroyed, with 120 killed and 220 captured. Partisans also captured 4 howitzers 100 mm, 2 anti-tank guns 47 mm, 9 mortars 81 mm and 12 heavy and 25 light machine-guns. All of the tanks were captured or destroyed: 9 of them were captured in Prozor area, and 2 were captured later in Ostrožac, and all 11 were used for the formation of the Tank Company of the Supreme Command. The Italian reinforcements sent earlier that day were also destroyed: 1st Battalion of the 260th Regiment near Drežnica, and a company of 1st Battalion of the 259th Regiment, sent from Konjic, was destroyed near Prozor.
According to the popular myth, on the eve of the attack, a conference in the 3rd Division HQ was interrupted by the arrival of a courier with a note from Tito (who was in nearby Šćit). The note simply read: "Prozor must fall tonight" (Prozor noćas mora pasti). Historical records and participants' memories are divided on the subject, but the phrase became popular, and entered into everyday speech and pop culture.
The offensive continued with the 10th Herzegovina Brigade of the 3rd Partisan Division attacking and routing a company from the 1st Battalion of the 259th Regiment in Rama on 20 February, inflicting losses of 183 killed and 7 captured Italian soldiers. On 22 February, the 5th Proletarian Brigade of the same division captured Ostrožac on Neretva.
In the meantime, the 4th Proletarian Brigade from the Right Column captured further 270 Italians, 140 of which in the town of Jablanica, which was taken on 22 February. Among the captured were Lieutenant Colonel Pelleroni, commander of the Jablanica garrison, and Colonel Malantonio, Commander of the 259th Regiment. Colonel Malantonio was shot after the Partisans had determined that he was a prominent member of the Fascist Party, and that he had taken part in the Spanish Civil War as an officer in the Italian Corpo Truppe Volontarie. With the fall of Jablanica, Partisans were in control of the entire Neretva valley between Mostar and Ivan Sedlo; only the strategically important town of Konjic was still in Italian hands.
The Left Column (1st Proletarian Division) was only partially concentrated, but decided to go ahead with the plan using only two if its brigades. The main objectives on the railway line Sarajevo - Konjic, Ivan sedlo and Raštelica, were defended by the Ustaša Railroad Battalion, and important railroad objects Bradina, Lukač and Brđani were defended by up to a company strong Italian units in strong fortifications. The 1st Proletarian Brigade captured the important mountain pass Ivan Sedlo and Raštelica station on 17 February by a coup de main. The Italian fortifications were overcome on 18 February, after some artillery and mortar fire exchange, and after an intervention attempt by an armored train from Konjic had been repulsed. In that situation, with no enemy activity from Sarajevo, the 1st Proletarian Brigade headquarters made a critical error in judgment by sending two battalions to attack the railway station Tarčin near Sarajevo, and the remaining two battalions on a surprise attack attempt on Konjic, thus leaving the most important object in its area, Ivan sedlo mountain pass, virtually unoccupied.
The surprise raid on Konjic was conceived with the intention of exploiting the demoralization among the Italians, and with the hope of establishing contact with the 5th Brigade of the 3rd Division for the joint attack. But, the contact was not established, and in the night on 19/20 February, two battalions of the 1st Proletarian Brigade attacked the main target of the whole Partisan operation, the Konjic garrison, unsupported. The attack had some initial success, and the defenders were thrown back from the right bank of the river. However, since only two partisan companies managed to cross the river and enter the town center, they were easily halted by heavy mortar and artillery fire. Seeing that no progress was to be made by dawn, the Brigade Headquarters cancelled the attack.
The other two battalions of the brigade attacked Tarčin in the night 20/21 February. The attack coincided with the arrival of the German reinforcements from Sarajevo. As the Partisans were largely outnumbered, the Germans succeeded in throwing them back, and resuming their movement towards Ivan sedlo. The appearance of German units in Tarčin marked the beginning of the operation Weiss Mostar.
By the third week of February the Partisans had managed to breach the Italian blocking force along the Neretva River, thus compromising one of the main aspects of the operational plan for Weiss 2. Worst of all, the Partisans captured Posušje and endangered the wider Mostar area, which provided the German war industry with 10 percent of its bauxite ore needs. Since Italian troops were seemingly incapable of containing the situation, the German Command was compelled to adjust the operational plans accordingly. It was decided to deploy 718th Division immediately to the endangered areas, even before the Weiss 2 was launched.
The 718th Division started its attack on 19 February, with one column advancing from Bugojno towards Gornji Vakuf and Prozor, and the other from Sarajevo towards Konjic. Jablanica was the ultimate objective of both pincer arms. The column from Bugojno, named “Battle Group Vogel”, consisted of the 738th Regiment (minus one battalion), the 5th Ustaša Brigade (the so-called “(Ustaše militia)|Black Legion]]”) and artillery. It captured Gornji Vakuf on 22 February, and then found itself stuck in a ten day long battle against the reinforced 7th Banija Division in front of Prozor.
The column from Sarajevo (named “Battle Group Annacker”), consisted of the 750th Regiment (minus one battalion), two battalions of the 7th Home Guard Regiment, one Ustaša battalion, artillery, and one platoon of tanks. It was this battle group which attacked two battalions of the 1st Proletarian Brigade in Tarčin on 21 February. The group repulsed the Partisan attack on Tarčin, threw back Partisan battalions, and on the same day reached Ivan sedlo and Raštelica. After regrouping, the Partisans reclaimed their positions on the Ivan sedlo on the next day, but a substantial part of the battle group, including one German and one Home Guard battalion, an Ustaša company, and a number of tanks, succeeded in breaking through to Konjic on 22 February. They arrived just in time to decisively strengthen the garrison before a major Partisan attack. The commander of the 1st Proletarian Brigade Danilo Lekić had to answer in person to Tito for the failure of his brigade to seal off the approaches to lower Neretva Valley.
Attack on Konjic
The fact that Konjic controlled the only road leading to Eastern Herzegovina (the rest of the eastern bank of Neretva to the south of the town being dominated by the virtually unpassable Prenj mountain), made it the prime objective of the Partisan army. Konjic garrison originally consisted of the 1st Batttalion of the 259th Regiment with artillery elements and other units. During the fighting at Prozor, Rama and Jablanica parts of the Konjic garrison were sent as a reinforcement, and were destroyed. Division Murge as a whole in one week suffered losses of some 2,300 men, and was affected by panic and demoralization, and this caused a lot of optimism among Partisans. But, immediately before the main Partisan attack, two and a half battalion strong vanguard of the Battle Group Annacker entered the town. At the same time, some 3,000 strong Chetnik formation under Lukačević reached the town, and, in agreement with the garrison, assumed positions around the town. This way, it unexpectedly became a very difficult obstacle for the whole Partisan Main Operational Group.
The 3rd Division decided to storm the town by using two of its brigades (the third remained in Prozor), with one (the 5th Montenegro Brigade) attacking along the right bank of the river, and the second (the 10th Herzegovina Brigade) along the left. The hastily organized attack began in the evening hours of 22 February. Due to insufficient intelligence, the 10th Brigade ran into strong Chetnik concentration on the eastern bank and could barely reach the town before dawn. On the opposite bank, the 5th Brigade faced stiff resistance by German and Italian forces, achieving little success. As a result, the 3rd Division saw no alternative but to cancel the attack by the morning of the 23rd.
For the next attempt, on 24 February in the evening, the attacking forces were reinforced with the 4th Montenegro Brigade from the 2nd Proletarian Division, and with the Tank Company of the Supreme Headquarters. The attack went on through the whole night, and resumed the next night, but to no avail. In a report, Germans praised the "help of the brave Chetniks".
As the blockade of Ivan Sedlo Pass by the 1st Proletarian Division seemed to be holding, and no further parts of the battle group Annaker reached Konjic, Tito decided to send another brigade to Konjic. Early on 26 February, the 3rd Krajina Brigade left its positions around Prozor, and started the march to the embattled town. However, after only few hours, it was summoned back. The appearance of the 717th Infantry Division (now attacking Prozor instead of Livno, as originally envisaged by the plan for Weiss II) on the flank of battle group Vogel endangered the whole western front of the NOVJ; the Central Hospital at Šćit was now directly exposed to the German onslaught. Consequently, the attack on Konjic by using additional forces from the Prozor area had to be cancelled.
At this stage, Tito and his HQ had suddenly found themselves facing an entirely different situation from the one they faced only days earlier. By 20 February, the prospects looked good for the “Main Operational Group”: all but one Italian garrison in the Neretva Valley were destroyed and the road to Eastern Herzegovina looked open. Now, the road was blocked by unexpectedly strong resistance in Konjic, and the Partisan army was hemmed in the narrow Neretva valley surrounded on all sides by strong enemy concentrations: On 25 February Germans launched Weiss 2, attacking Drvar, Glamoč and Livno with two divisions; the Italians in Mostar regrouped, and fielded two battle groups with Chetniks support for the attack up the river; further strong Chetnik concentrations were detected on the eastern bank of the Neretva. Consequently, the plans had to be revised, and tough decisions had to be made.
Based on the gathered intelligence, German command concluded that Livno was the center of the southeastern half of the Partisan territory. For that reason, the Weiss 2 has been conceived as a concentric attack on Livno, with the assumption that the Partisans would be pushed back, encircled and destroyed there. In the meantime, the situation had changed. The Partisans broke into Neretva valley, and their main concentration was now between Prozor and Konjic. In spite of this, German command largely proceeded with the original plan. In light of the recent developments, however, first one (718th), and after a week another (717th) division were directed towards the new flashpoint.
Two divisions, the 7th SS and the 369th, were used for the operation Weiss 2. Their advance commenced on 25 February. The route assigned to the 7th SS Division was from Bosanski Petrovac, over Drvar and Bosansko Grahovo to Livno, while 369th Division had to cover the route from Mrkonjić-Grad over Mliništa and Glamoč to Livno. In front of them stood six (out of altogether ten) brigades of the Partisan 1st Bosnian Corps. The plan of the Corps Headquarters did not call for decisive defense. The units would put up just enough resistance in order to allow the units and the population to be evacuated, and would thereafter merely evade the German advancing columns. The 7th SS division captured Drvar on 28 February, and continued towards Grahovo, pushing back 8th, 9th and 10th Krajina Brigade. On the road to Glamoč, 4th and 7th Krajina Brigade were slowing down the 369th Division. As the 7th SS Division reached Grahovo, and the 369th Glamoč on 2 March, the Corps Headquarters decided to perform the evasion maneuver, and the brigades, together with a mass of the refugees, commenced their march over Šator Mountain towards Rore, and back to the Krajina. Because of the freezing weather and deep snow, this march over high mountain area cost many civilian lives. The Germans invested large efforts in pursuing the Partisans through the mountain, but the Partisans remained elusive, and the only result was the capture of a number of exhausted refugees.
After this maneuver, all the units of the 1st Bosnia Corps found themselves out of the reach of advancing Germans, except the 7th and 9th Krajina Brigades. They were temporarily subordinated directly to the Supreme HQ which had ordered them to slow down the German advance towards Neretva. On 5 March, the two German divisions had finally reached Livno and taken it without a fight. After several days of rest, the 7th SS Division resumed its movements to the Mostar bauxite area without Partisan interference, and 369th Division headed towards Jablanica.
Further to the south, the group of Herzegovina Chetnik units under Baćović was marching from Split towards Neretva. This group had been transported by the Italians by sea and land to Knin in December 1942 in order to fight the Partisans in Lika. In early February 1943, the group was first returned to Split and then ordered to make an overland march to Neretva. While passing through the Biokovo hinterland, the group committed numerous crimes against civilian population. Around Vrgorac, the group encountered the elements of the 9th Partisan (Dalmatian) Division. The division, deployed in the broader area of Imotski, was already under pressure from the east (Italian regimental battle group “Scotti” from Mostar) and the south-east (Montenego Chetniks under Vesković from Ljubuški). Facing such odds, the division had to retreat towards Jablanica, where it became a part of the Main Operational Group.
Battle of the Neretva
In the last days of February, Tito's Main Operational Group found itself in a critical position with no open road remaining. On the one side it was stuck in front of the stubborn defense of the Konjic garrison, and on the other, it was exposed to the mounting pressure on Prozor. There was also constant pressure of the reinforced parts of the 718th division from Sarajevo, increasing pressure of the Italian-Chetnik battlegroups from Mostar, build-up of further Chetnik forces on the eastern bank of Neretva, and further two German divisions (7th SS and 369th) were approaching from the west. The alarming news about the imminent threat to the Central Hospital were arriving in Tito's HQ on a daily basis.
In that situation, Tito took firmly the tactical command in his hands. On 28 February he decided to reverse the direction of the attack, and, instead of pushing over Neretva, to strike hard at the Germans pressuring Prozor. According to this new orientation, he ordered the Pioneer Company to destroy all the bridges across Neretva, which was done between 1 and 4 March. He also ordered all the forces to concentrate against Gornji Vakuf, with only necessary rearguards left on Neretva.
Counterattack at Gornji Vakuf
The counterattack began not a minute too soon. The 717th Division and the battlegroup Vogel were attacking along the road Gornji Vakuf – Prozor with the main column, while trying to circumvent the partisan defense with flank columns over Pidriš and Vilića gumno, intending to capture the important pass Makljen. On 2 March at dawn, 4th Proletarian Brigade, led by its 2nd Battalion, bypassing the columns of the wounded from the Central Hospital, reached Vilića gumno, and assumed positions in the deep snow, 30 to 50 meters from German lines, to be attacked almost immediately by the German 749th Regiment. After several hours of defense, the Brigade charged the enemy positions and pushed the Germans back down the slopes of Raduša mountain. The fighting was intense and dramatic, under hard circumstances, and the losses were serious. The report for that day counted 51 killed, 83 wounded, 21 missing and 31 cases of frostbite. On the other side, 3rd Company of the 2nd Battalion fell down to only 8 men. For this success, the 2nd Battalion and its commander Niko Strugar were officially commended by Tito.
During 2 and 3 March brigades were arriving to Prozor and assuming their positions along the line of fire. On 4 March, full-scale Partisan counterattack was launched with all nine brigades. Five brigades were attacking German positions frontally, and the remaining four were trying to circumvent the flanks. The Germans were pushed back all the way to near Bugojno, and they remained there waiting and preparing for defense until 8 March. In the fight on 4 March Partisans captured Major Strecker, Commander of the 3rd Battalion of the 738th Regiment, and in following days used him to propose prisoner exchange and talks on some other subjects to Germans. This led to the famous March negotiations.
Forcing the way over Neretva
The German Command was successfully surprised with the Partisan attack at Gornji Vakuf, and deeply concerned with it. On the assumption of the continuation of Partisan advance towards Bugojno, General Lüters on 6 March ordered to the 369th Division to reinforce German units there, noting in the War diary that "the key error (was) G.Vakuf". However, Tito was not pleased with the prospects of the advance over Bugojno and back to the Vrbas valley, fearing of the possibility of getting encircled by the German reinforcements in the narrow valley. So he ordered a new radical turnaround, the final push over Neretva, this time surprising not only the Germans, but also his closest associates.
The key role in forcing the way over Neretva was assigned to the 2nd Dalmatian Brigade. During the Gornji Vakuf counterattack preparations, 2nd Dalmatian Brigade was left on Neretva as a rearguard. Receiving the defensive task, its commander Ljubo Vučković didn't consider the possibility of the another change of the direction that was to follow. He ordered evacuation of Jablanica, and deployed the Brigade at suitable mountain positions nearby. However, on March 4, Tito summoned him to the meeting to criticize him for leaving Jablanica, and to order him to immediately reoccupy it, to cross Neretva with the Brigade on the following night, to push the Chetniks back from the bank, and to secure a bridgehead.
Reocupation of Jablanica turned out to be easier than it was assumed. It was held with two battalions of the Durmitor Chetnik Brigade. Since the Tank Company was available for the task, it was pushed ahead, in front of the attacking Partisan battalion. After seeing tanks, the Chetniks came out to meet them, assumed that it was the Italian relief column. Tank Company took advantage of the Chetnik confusion, and opened fire on them, causing panic and flight. However, the Brigade spent the whole day on the consideration of various options for crossing the. Since the pioneer detachment did not come until late in the evening, Vučković informed the Supreme Command of the impossibility of crossing Neretva during the same night. On the following day, on 6 March, the Brigade was reinforced with the arrival of the 2nd Proletarian Brigade. When the night fell, the troop of 12 men from the 2nd Company of the 3rd Battalion of the 2nd Dalmatian in the pitch dark climbed over the broken structure of the old bridge in Jablanica. The Chetniks from the bunker on the other side became aware of some activity, and began firing blindly, killing two soldiers. The other ten succeeded to climb up to the other bank and to destroy the Chetnik bunker with hand grenades. After them, the rest of the battalion followed over the broken structure, and after it two battalions from the 2nd Proletarian Brigade. These three battalions on the next day scattered the Chetnik Durmitor Brigade, whose soldiers have fled deep into the rear, spreading panic among other Chetnik units. With this success, the bridgehead was secured, and the pioneers started their work of constructing the new improvised bridge, supported by the broken construction of the old one.
The new Tito's plan of the operation was to push back Germans from Prozor to gain space and time for the manoeuvre, and than to storm over the Neretva at Jablanica as fast as possible. The new attack on Konjic was not intended. Instead of marching along the road through Konjic, the bulk of the Main Operational Group, with the Central Hospital and other non-combat parts, was to cross the slopes of Prenj near Konjc. It was impossible to transport the tanks, trucks and heavy artillery along this route, and it was ordered to be destroyed and abandoned.
On of the necessary preconditions was the firm blockade of Konjic. After the 1st Proletarian Brigade had left Ivan sedlo to participate in the Gornji Vakuf counterattack, the bulk of the 718th Division, together with the Headquarters, arrived to Konjic. These forces were pressuring Partisan rearguards in the first days of March, and succeeded to push them over Neretvica, some 10 km to the west. On 5 March, the 3rd Partisan Division Commander Pero Ćetković received and orger to push the Germans back to Konjic, and to close them firmly there. In fighting from 5 to 9 March, the Germans were thrown back to Konjic, and the Partisans reclaimed Ostrožac and other positions on Neretva.
The final push over Neretva was to be carried out in this formation:
- 3rd Division on the left flank, with the task of blocking Konjic,
- 2nd Division reinforced with 1st Proletarian Brigade, as the central column, had the main task to force its way over Neretva at Jablanica, and to penetrate over the northern slopes of Prenj to the upper Neretva at Ulog and Obalj,
- 7th Division with its two brigades was deployed on the right flank, with the task to, after crossing the Neretva at Jablanica, to circumvent Prenj from the south, and to block the paths from Mostar at Zijemlje
- 1st Division with the 7th Krajina brigade instead of the 1st Proletarian, had a task, as a rearguard, to slow down the German advance from Bugojno towards Jablanica, and to secure the crossing over the Neretva at Jablanica,
- 9th Division had a task to close the access to Neretva from the south and south-west.
In order to counter this strategic "checkmate", the Partisan commander, Josip Broz Tito, prepared an elaborate deception. He ordered his sappers to actually blow up all the bridges on the river. When air reconnaissance brought this information to the German command, they concluded that the Partisans must be preparing a final dash north of their current position (along the western shore of the Neretva), and had blown up the bridge to prevent desertion as well as attack by Chetnik forces from the other side of the river. They thus began a redeployment of troops in the area to block the anticipated movement.
This redeployment gave the Partisan engineers precious time needed to sufficiently repair the bridge and to eliminate the Chetnik troops defending its far side. The Germans, characteristically, quickly caught on, but were unable to correct their mistake and prepare a serious attack in time, because of their previous redeployment orders. With their rearguard fighting off an increasingly powerful German advance, the Partisans crossed the river under intense air bombardment (the Axis deployed large Luftwaffe formations), but the mountainous landscape prevented accurate destruction of the makeshift bridge. After the escape was complete, the weak bridge was finally rendered useless to prevent pursuit. The humiliating strategic defeat was amplified by Tito being able to keep his well known pledge not to leave the wounded behind, as they faced certain execution at the hands of the Axis (which later actually happened in the aftermath of the Battle of the Sutjeska).
The operation marked the "high point of Chetnik collaboration with the Axis powers". In order to ensure the operation's success, Draža Mihailović relocated from Montenegro to Kalinovik where Zaharije Ostojić, commander of operations in Herzegovina, was situated. On 9 March, Mihailović informed Colonel Bajo Stanišić:
"I manage the whole operation through Branko [Zaharije Ostojić]. No action is ordered without my approval. Branko is keeping me informed of even the smallest details. All his proposals are reviewed, studied, approved or corrected. In this we follow these principles: we work for ourselves alone and for no one else; we are concerned only with the interests of the Serbs and of future Yugoslavia; for the achievement of our objectives we use one enemy against another, precisely as do all our enemies with exception, and achieve our objectives with the least sacrifice, but are prepared even for the greatest sacrifices if this is necessary in the general interest, and to safeguard the people from all unnecessary exposure to danger in their homes."
By the end of March, the Germans claimed to had killed about 11,915 Partisans, executed 616, and captured 2,506. Despite these heavy losses and a tactical victory for the Axis powers, the partisan formations secured their command and the hospital, and were able to continue operations. In fact, once they reached the eastern parts of Bosnia and Herzegovina, the Partisans had to face only the Chetniks, and in turn almost entirely incapacitated them in the area west of the Drina river.
The next major operation in Yugoslavia was Operation Schwarz.

In popular culture
Alistair MacLean's 1968 thriller novel Force 10 From Navarone, subsequently filmed, also brings forth the fight of outnumbered Partisans against Germans and Chetniks, and the blowing up of the Neretva bridge. But the actual historical events are not in play, and the story is entirely fictional.
