General Jacob Loucks "Jake" Devers (September 8, 1887 – October 15, 1979) was the commander of the Sixth United States Army Group in the European Theatre of World War II. His units were the first United States Army units to reach the Rhine after the Normandy landings.

Early life and education[edit]

Devers was born on September 8, 1887, in York, Pennsylvania, a small industrial town in the southeastern corner of the state. His parents were Philip Devers, a watchmaker and partner in a jewelry store, and Ella Kate Loucks Devers, a homemaker. He was the first of the couple's four children.[1] The Devers, of Irish and German-Alsatian ancestry were strict, hard working and religious. The family were members of the Evangelical Lutheran Church which did not believe in smoking or drinking. While providing a comfortable middle-class life for their children, the couple taught them to value dependability, integrity and industriousness.

Growing up in the heart of Pennsylvania Dutch country, young Jake Devers enjoyed the outdoors: camping, fishing and hunting. He played all the usual boyhood sports and made friends easily with his engaging smile and cheerful personality. In addition to his household chores, he did odd jobs around the neighborhood and worked on his maternal grandfather Jacob Loucks' farm. Devers entered York High School in September, 1901. A popular student, he was elected Class President. He had an excellent academic record earning high marks in mathematics and science. Always competitive though slightly built, the 120-pound 5-foot 10-inch Devers captained the basketball team, played quarterback in football and starred in baseball. After graduating from York high school in May, 1905, Devers accepted a Congressional appointment to the U.S. Military Academy at West Point, New York. He entered the Academy in June with the Class of 1909. Among his classmates were George S. Patton, Jr., William H. Simpson, and Robert L. Eichelberger, all of whom (including Devers) would become four-star generals in World War II. Devers did well in his studies, and he excelled in sports, playing shortstop on the Army baseball team and guard on the Black Knights's basketball squad. He graduated from West Point in June, 1909, ranking 39th in his class of 103, and was commissioned a Second Lieutenant in his specialty branch: Field Artillery.

Military career: between the wars[edit]

Devers' first posting was to the 4th Field Artillery Regiment, 1st Battalion, based at Vancouver Barracks in Washington state. The unit soon moved to Fort David A. Russell, Cheyenne, Wyoming. There Devers commanded a Company of Field Artillery, horse-drawn and pack mule-supplied. On October 11, 1911, Devers married Georgie Hayes Lyon of Arlington, Virginia, visiting niece of his Fort Russell commanding officer.

For his next assignment in December, 1912, Devers was sent back to West Point to teach mathematics. He also managed the baseball program and coached the Cadet basketball team from 1914 to 1916. In April, 1916, Devers was promoted to First Lieutenant. That August Devers was transferred to the newly activated 9th Field Artillery Regiment at Schofield Barracks, Oahu, Territory of Hawaii. The United States entered World War I against Germany April 6, 1917. A disappointed Devers, promoted to Captain in May, did not see action in The Great War. The Devers' only child, daughter Frances Lyon, was born August 2, 1917. Devers was posted to the Army Artillery School at Fort Sill, Oklahoma, in late December to serve as an instructor in the School of Fire. Just weeks before the World War I Armistice, November 11, 1918, he was named Executive Officer of the 9th Field Artillery Regiment, his former unit from Hawaii now at Fort Sill. Devers was made Commanding Officer of the 1st Field Artillery Regiment at Sill in March, 1919. In June Devers was sent on a three-month temporary duty assignment to Europe with the American Army of Occupation. He attended a French artillery school to study guns, ammunition, equipment and tactics used by the Allies and the Germans during the war. Then it was back to West Point for Devers. Promoted to Major in July, he began his second tour of duty at the Academy in August, serving as Senior Field Artillery Instructor and Commander, Field Artillery Detachment. He served on the staff of Academy Commandant Brigadier General Douglas MacArthur.

After five years at West Point (1919-1924), Devers was selected to attend the Army's Command and General Staff School at Fort Leavenworth, Kansas. He began his studies there in September, 1924, and finished as a Distinguished Graduate in June, 1925. Posted once again to hot and dusty Fort Sill, Devers directed the Field Artillery School's Gunnery Department for four years (1925-1929). During his tour he was credited with making a number of innovative artillery tactical and technical improvements, including advanced fire-support techniques successfully used during World War II.[2] In September, 1929, Devers was ordered to Washington, DC, to serve on the staff of the Army's Chief of Field Artillery (Operations and Training) Lieutenant Colonel Adna R. Chaffee, Jr. Chosen to attend the Army War College in Washington, he began his studies there in August, 1932, and graduated in June, 1933. After a one-year assignment to Fort Hoyle, Maryland, with the 6th Field Artillery Regiment, in June, 1934 Devers, a Lieutenant Colonel since February, was sent to Fort Myer, Virginia, near the District of Columbia, as Commander of the 1st Battalion, 16th Field Artillery Regiment. In 1936 it was back to the Military Academy for the third time for Devers. He remained at the Point for three years (1936-1939) on the Headquarters Staff as Executive of Construction and Graduate Manager of Athletics. Devers was promoted to full Colonel in July, 1938. Named Chief of Staff to Major General Daniel Van Voorhis, Commander of the Panama Canal Department, Devers transferred to the Canal Zone in August, 1939. The invasion of Poland and the subsequent declarations of war by Great Britain and France against Nazi Germany, marked the beginning of World War II.

World War II[edit]

On the recommendation of Army Chief of Staff General George C. Marshall and with the approval of Secretary of War Henry H. Woodring, Devers was advanced in rank to Brigadier General in April, 1940. His promotion over 474 other Colonels made him at age 52 the youngest Brigadier in the Army.[3] In July Devers was recalled to Washington from the Panama Canal Zone to assume command of the District's Provisional Brigade. That September General Marshall, with the approval of new Secretary of War Henry L. Stimson, named Devers Senior U.S. Army representative to the Presidential Board tasked with surveying bases in the Caribbean and Newfoundland to be leased from the British as part of the Destroyers for Bases Agreement.

9th Infantry Division Fort Bragg, NC[edit]

Devers was promoted to two-star Major General in October and sent to command the newly formed 9th Infantry Division at Fort Bragg, Fayetteville, North Carolina. He would supervise training of the 9th while managing Bragg's huge base expansion program. Devers directed basic and advanced infantry training at Bragg for the thousands of troops under his command: Regular Army, National Guard, Reservists and draftees. During Devers' tour Fort Bragg's strength grew from 5,000 to 66,000 soldiers. At the same time, he pushed forward immense construction projects for base housing, training facilities and roads on the overcrowded post. By working closely and cooperatively with engineers, local contractors, quartermasters and staff—and by cutting through red tape—in six months Devers oversaw completion of 2,500 buildings and 93 miles of roads.

Chief of the Armored Force Fort Knox, Kentucky[edit]

In August, 1941, General Marshall named Devers Chief of the Armored Force,[2] which was headquartered at its "Home", Fort Knox, Kentucky. Devers replaced a mechanized cavalry legend, the terminally ill general Adna R. Chaffee, Jr., who just twelve months before had been appointed the first Chief of the newly created Armored Force.[2] Devers would report directly to General Marshall [4] and would be responsible for inspecting, organizing and training the Army's Armored Divisions and separate non-divisional Tank Battalions, including all nontank personnel assigned. Army General Headquarters (GHQ), commanded by General Marshall's Chief of Staff, Lieutenant General Leslie J. McNair, was in tactical charge of all U.S. ground forces. But GHQ specifically did not control the semi-autonomous Armored Force, which was considered "provisional" and would not become a full "Branch" until 1955.[4]

At the time Devers took command, the Armored Force had just two operational Armored Divisions: the 1st at Fort Polk, Louisiana, and the 2nd at Fort Knox.[2] Both participated in the large-scale two-phase corps vs. corps GHQ 1941 Maneuvers. These war games, the so-called Louisiana Maneuvers, were held in Louisiana in September and the Carolinas in September. Despite some successes, the maneuvers revealed armored unit and equipment operational deficiencies, plus a general lack of combat readiness.[2] In particular, post-maneuver reports showed a vulnerability of U.S. tanks to antitank fire. This bolstered the pro-antitank philosophy strongly held by General McNair. Devers differed, countering that the number of tank "kills" credited to antitank gunners was unrealistic and biased.[5] General McNair continued to push for an independent "tank destroyer force". Devers argued that the best weapon against a tank was a better tank. Nevertheless, in November General Marshall authorized creation of such a force. Battlefield experience would prove that Devers was right. In combat tank destroyers were mainly used as mobile artillery support. At the end of the war, the Tank Destroyer Force was disbanded.[6]

A new medium tank was beginning to come off the production line: the M3 Grant. But Devers lobbied, sometimes against the views of his superiors, for a still more heavily armored and better armed medium tank, the M4 Sherman. Devers played an important role in the M4's design, development and manufacturing, particularly its engine and armament.[2] The Detroit Tank Arsenal began turning out Shermans in the Fall. The reliable, versatile, low-cost M4 and its variants would prove to be the most-produced tank in the U.S. Army during World War II. Throughout his tour as Chief of the Armored Force Devers worked closely with the Ordnance Department, manufacturers and the Armored Force Board at Knox on the research and testing of tanks, guns, armored vehicles and ammunition. After the GHQ Maneuvers, the Army expected to have a period of "remedial training" to fix problems. The Japanese attack on Pearl Harbor December 7, 1941, shattered those expectations and plunged a not fully prepared United States into the war.[7]

At the beginning of 1942, two Armored Divisions were operational, five were in training and two more scheduled to be activated in February. Army planners called for the eventual formation of 16 armored divisions and 54 Tank Battalions.[2] Activity at Knox accelerated. The Armored Force Replacement Training Center (RTC) gave arriving soldiers twelve (later 17) weeks of training before they were sent on to armor units. The Armored Force School provided advanced individual training in specific areas such as gunnery, field tactics, communications and maintenance. And the Armored Force Officer Candidate School prepared selectees to serve as Commissioned Officers in Armor.[2] With so many men undergoing training existing bases were overwhelmed. Devers had to oversee a massive construction of barracks, facilities and infrastructure, particularly at Fort Knox.[8] A large maneuver area where soldiers could train for desert warfare was sorely needed. Devers sent General Patton, now commander of I Armored Corps which included the 2nd Armored Division, to set up the Desert Training Center (DTC) in the California-Arizona Mojave Desert.[2]

Devers was an articulate proponent of the Army's now-emerging tactical doctrine of combined arms: Infantry-Artillery-Armor-Close Air Support.[2] At his direction an updated, comprehensive (460 pages) Armed Force Field Manual: Tactics and Technique FM 17-10 was written, published and distributed in March, 1942.[9] Also in March, a major reorganization of Army Headquarters was ordered by General Marshall. General McNair was named Commander of a new component, Army Ground Forces (AGF), which replaced GHQ.[4] Relations between GHQ/AGF and the Armored Force were distant and lines of authority and responsibility were often unclear. General McNair seemed to prefer leaving Devers alone.[10] Under a new Table of Organization and Equipment (TO&E) originally proposed by Devers, Armored Divisions were downsized. For all but the 2nd and 3rd Armored Divisions, the number of regiments was cut from six to three: two tank and one armored infantry.[2] In a first, at Devers' insistence, a flight of light aircraft to be used for artillery spotting, recon and liaison were included in the new TO&E for each division.

With the approval of U.S. President Franklin D. Roosevelt and British Prime Minister Winston Churchill, during April the Combined Chiefs of Staff (CCS) reached agreement on Operation ROUNDUP which called for cross-Channel landings by the Allies on Continental Europe in 1943.[11] In May the CCS agreed to Operation BOLERO, a plan to transport and base 1,000,000 U.S. soldiers and airmen and their equipment in the British Isles to support ROUNDUP.[12] Operation TORCH, an Anglo-American invasion of French Vichy-held Northwest Africa planned for Fall and backed by Prime Minister Churchill was reluctantly agreed to by President Roosevelt in June.[13] ROUNDUP had to be put on hold. In August, Lieutenant General Dwight D. Eisenhower, Commanding General European Theater of Operations U.S. Army (ETOUSA), was named Commander-in-Chief Allied Force Headquarters (AFHQ) to lead the TORCH landings, planned for late Fall.[13] The 1st and 2nd Armored Divisions were assigned to the Operation.

Increased pressure was on Devers, promoted to three-star Lieutenant General (equal in rank to General McNair) in September,[2] to push more armored units through the pipeline even faster. Training was sometimes neglected because of the pressing need to get units ready for overseas deployment. Despite obstacles such as lack of personnel trained in critical Military Occupational Specialties (MOS) and a persistent shortage of tank engines [14] the Armored Force Chief succeeded in getting divisions and battalions to their Ports of Embarkation (POE) on time. American and British forces went ashore at Casablanca, Oran and Algiers on November 8, 1942, as Operation TORCH was launched.[13] So far during the year seven more Armored Divisions had been activated. At peak strength, some 225,000 soldiers were either trainers or in training under Dever's command. On a battlefield inspection tour, Devers flew to the United Kingdom in mid-December. He continued to North Africa in January, 1943. Returning to Fort Knox at month-end, he supervised implementation of ideas for making armor training more realistic, reflecting actual combat experience.[15] The 20th Armored Division was activated March 15. Only one more, the 16th, remained to be organized.[2]

On May 3, while on an aerial inspection tour, Army Air Forces Lieutenant General Frank M. Andrews, ETOUSA Commander since replacing General Eisenhower in February,[16] was killed in an aircraft crash in Iceland. With the approval of President Roosevelt, four days later General Marshall named Devers to take command of ETOUSA.[17]

European Theater of Operations U.S. Army (ETOUSA)[edit]

Devers arrived at ETOUSA Headquarters, 2 Grosvenor Square, London, May 10, 1943. As Commanding General and the ranking American officer in the European Theater, his wide range of duties would include everything from overseeing preparation of detailed planning and estimates of men and materials needed for Operation OVERLORD (formerly ROUNDUP), to making public appearances at ceremonial and morale-building events.

ETOUSA exercised operational and administrative control over all U.S. Army units and installations in the United Kingdom and Iceland. Its territorial boundaries were all of Western Europe (including Germany)from the North Atlantic to North Africa. Three major subordinate commands made up ETOUSA: the V Corps (Army Ground Forces); the Eighth Air Force (Army Air Forces); and, the Services of Supply (service forces). By then the number of American soldiers and airmen in the U.K. serving under Devers totalled 110,818.[18]

The Eighth Air Force, under the command of Brigadier General Ira C. Eaker since January, had been flying bombardment missions (55) against the enemy for almost a year. It was the only U.S. Army organization carrying the war from England to the Germans in Occupied Europe. Commanded by Lieutenant General Leonard T. Gerow, V Corps was functioning in a training role. It managed the tens of thousands of American ground troops arriving in the British Isles stationed in staging areas to the south. The Services of Supply (SOS) had recently been consolidated under Lieutenant General John C.H. Lee, who also served as Deputy Commander, ETOUSA.

The Combined Chiefs of Staff (CCS) had directed that the Commanding General of ETOUSA, should be considered the direct representative of the U.S. Chiefs of Staff and that as such he should be consulted on all plans involving American troops.[11] The previous month the CCS had appointed British Lieutenant General Frederick E. Morgan Chief of Staff to the Supreme Allied Commander (designate), or COSSAC as it was called, an Anglo-American planning group tasked with making preparations for OVERLORD.[11] COSSAC included ETOUSA staff members on its committees and Morgan's proposals were referred to Devers for comment. Devers was awarded his first Army Distinguished Service Medal November 11, 1943, for "his untiring efforts in the rapid expansion, direction and training of the Armored Force."

On December 7, 1943, President Roosevelt with the approval of Prime Minister Churchill named General Eisenhower Supreme Allied Commander Headquarters Allied Expeditionary Forces (SHAEF) for OVERLORD. General Eisenhower was then serving as Commanding General Mediterranean Theater of Operations (MTO).[19] As part of an ongoing swap of top commanders and staff between the ETO and the MTO, on December 31 General Marshall named Devers Commander North African Theater of Operations U.S. Army (NATOUSA) and Deputy Commander MTO. General Eisenhower replaced Devers as Commander ETOUSA.

North African (NATOUSA) and Mediterranean Theater of Operations (MTO)[edit]

At the beginning of 1944, Allied ground forces in Italy remained bogged down in front of the German's Winter Line which stretched coast to coast south of Rome. This chain of strong defensive positions in mountainous terrain was anchored in the middle by the Gustav Line at Monte Cassino. Facing the Germans were, from west to east, the British X Corps under Lieutenant General Richard McCreery; the U.S. Fifth Army led by General Mark W. Clark; and, the British Eighth Army commanded by Lieutenant General Oliver Leese.

Devers arrived in Algiers, Algeria, January 3, 1944, to take command of NATOUSA, a logistical administrative organization which included General Clark's Fifth Army, the U.S. Twelfth Air Force led by Lieutenant General John K. Cannon; and, the Services of Supply headed by Lieutenant General Thomas B. Larkin. Some 600,000 American soldiers and airmen were serving in NATOUSA, which stretched from French Morocco to the Balkans.

British General Henry Maitland (Jumbo) Wilson, now Supreme Allied Commander Mediterranean Theater of Operations (MTO), headed Allied Forces Headquarters (AFHQ) and was responsible for directing all operations in the Theater. Devers was named Deputy Supreme Allied Commander Mediterranean Theater of Operations.[20] Devers' NATOUSA functioned simultaneously as a U.S. Army headquarters and as the American component of AFHQ, which directed the activities of Allied Ground Forces in Italy (AAI) headed by British General Harold Alexander; Mediterranean Allied Air Forces (MAAF) commanded by General Eaker (who had also been transferred from the ETO to the MTO); and, Mediterranean Allied Naval Forces led by British Admiral Sir John Cunningham.

Operation SHINGLE, General Clark's plan for a surprise end run to outflank the German Winter Line, called for Allied landings at Anzio-Nettuno on Italy's west coast thirty miles south of Rome. SHINGLE was to take place in less than three weeks. Devers, who had nothing to do with planning the Operation, quickly immersed himself in studying its details, particularly its logistical supply needs. SHINGLE began January 22 as some 36,000 American (3rd Infantry Division) soldiers and British troops of VI Corps under the overall command of U.S. Major General John P. Lucas came ashore unopposed at the seaside villages of Anzio-Nettuno. In coming days the Allies pushed their 20-mile beachhead three to four miles inland against steadily growing opposition. Reinforcements (the 45th Infantry Division and CCA of the 1st Armored Division) landed at the port January 25. General Lucas launched a two-pronged assault January 30 aimed at taking Caserta and Campoleone. But the defenders, reinforced by General Albert Kesselring the skilled German commander in Italy, beat back both attacks inflicting heavy losses on the attackers. Instead of the hoped-for quick breakout from the beachhead into the Alban Hills beyond, General Lucas ordered his troops to fall back and dig in.

At Monte Cassino the historic abbey overlooked Allied positions below. Ground commanders were sure the Monastery was being used by the Germans as an observation post. Major General Bernard C. Freyberg, Commander of the Provisional New Zealand Corps preparing for a new assault on the hill, had repeatedly requested that the abbey be bombed. Devers and General Eaker flew low over the monastery February 13, 1944, and reported seeing enemy soldiers moving in and out. General Wilson reluctantly agreed to its bombing. On February 15 waves of American bombers leveled the monastery. But follow-up attacks that day and for the next eight days failed to take the high ground.

The Germans' 100,000 men, facing General Lucas' 76,400, exploded against the Anzio beachhead February 16. Fierce enemy counterattacks were halted three days later after heavy losses on both sides. The stalemate continued. General Clark, with the concurrence of Devers and General Alexander, relieved a weary General Lucas February 22. He was replaced as VI Corps Commander by Major General Lucian K. Truscott, Jr., former head of the 3rd Infantry Division. Twelfth Air Force mediums and Fifteenth Air Force heavies obliterated the town of Cassino March 15, 1944, kicking off a renewed Allied offensive to crack the Gustav Line. General Freyberg's New Zealanders, backed by U.S. 1st Armored Division CCB tanks, advanced into the city. Street-to-street fighting with German paratroops amidst the rubble went on for the next ten days. As Devers had warned, the massive bombardment did not result in a breakthrough.

The continuing failure to advance in Italy prompted the CCS decision March 20 to hold up on executing Operation ANVIL, the on-again-off-again proposal for Allied landings along the coast of southern France coinciding with OVERLORD. But planning for ANVIL, begun in mid-January by AFHQ's covernamed "Force 163" Detachment based in Algiers went on.

AFHQ's Seventh Army, commanded by General Clark since General Patton was transferred to the U.K in January, was being held in reserve with no combat units and only a small headquarters on Sicily. The Seventh, whose troops had carried out the very successful campaign to capture that island the previous summer, was designated as the landing force to carry out ANVIL. On March 2, Major General Alexander (Sandy) M. Patch was named by General Marshall with the approval of Devers to be the new Seventh's Commander. General Patch had recently been transferred to the MTO from the U.S. along with his IV Corps staff. A combat veteran, he had led Army and Marine forces in the final months of the Guadalcanal Campaign in the Pacific. General Patch with a newly formed Seventh Army staff took over ANVIL detailed operational planning as well as the work of Force 163. Devers continued to oversee the ongoing supply buildup for the Operation.

Ground fighting at Anzio and Cassino quieted during April, 1944, as the Allies regrouped for a new offensive. Operation DIADEM was to be launched as soon as the spring rains ended. In the air an interdiction program appropriately named Operation STRANGLE was begun by MAATF. Objective was "...to reduce the enemy's flow of supplies to a level which will make it impracticable for him to maintain and operate his forces in Central Italy."[21]

Early in April the CCS had been forced to postpone ANVIL from coinciding with OVERLORD. The southern France landings were rescheduled for July 15, 1944, because of an anticipated shortage of critical LSTs (Landing Ship-Tank). A few weeks later, due to the continuing holdup in Italy, the CCS set ANVIL back once again, this time to August 1, 1944. DIADEM kicked off May 12, 1944, as four Corps of Allied troops at Cassino began still another attempt to take the high ground and open up the Liri Valley, the main route to Rome. By the 19th, the town and Abbey had been taken and the Gustav Line was cracked. In the days following, the Germans—closely pursued by Allied forces—retreated northward. At Anzio, VI Corps broke out on the 23rd and advanced to the east and north. On the 25th, General Truscott's soldiers linked up with U.S. II Corps units moving northwest from Cassino. On the evening of June 4, 1944, American troops entered Rome, undefended by the fleeing Germans.

Old differences between the Allies about what strategy to follow in the Mediterranean resurfaced. The British CCS and Prime Minister Churchill continued to favor pushing north in Italy for a possible drive into the Balkans. The Americans still backed ANVIL, the option strongly urged by General Marshall, General Eisenhower and Devers, who pointed out that only ANVIL could quickly open the vital Mediterranean ports of Toulon and Marsailles; help OVERLORD more directly by drawing off more German defenders to southern France; and, make the most effective use of substantial numbers of American-equipped French forces. The final decision was up to the two heads of State. On July 1, 1944, Prime Minister Churchill, at President Roosevelt's insistence and Soviet Union Premier Joseph Stalin's strong backing, unhappily agreed to ANVIL. The next day the CCS directed General Wilson to the launch the Operation August 15, 1944. After six months of uncertainty, ANVIL was more or less a firm commitment, just six weeks before it was to be carried out.

Seventh Army's Headquarters, which had remained on Sicily as a deception, had been closed in May and transferred to Oran and Algiers where Task Force 163 Army, Navy and Air Force planners from various levels were based. On July 4 both organizations were moved to Naples to make final ANVIL preparations as a united staff.[22] AFHQ shifted to Caserta. Over the next 30 days General Truscott's three veteran divisions of VI Corps were relieved from Fifth Army and reassigned to the Seventh. Troops were pulled out of the line and sent to camps at Pozzuoli (3rd Division) and Salerno (36th and 45th Divisions) to rest, refit and undergo amphibious assault training arranged by Devers' NATOUSA staff for ANVIL. The four French Expeditionary Corps divisions of II Corps were also relieved from combat in Italy and sent to staging areas around Naples. Three other French divisions in Algeria (I Corps) were moved to camps around Oran, likewise reassigned to Seventh Army under General de Lattre's command, reporting to General Patch.

Fascist sympathizers and Luftwaffe reconnaissance aircraft quickly reported Allied troop, ship and plane movements to German Intelligence. German field commanders were well aware of Allied strength massing for an assault, their general strategic intentions and the probable date of the Operation. It would later be said that ANVIL was "The Worst-Kept Secret of World War II."

By July 15 virtually all the material needed for the assault and support of American and French forces in southern France through D-Day plus 90 was on hand, on the way, or promised, thanks to Devers' efforts to "freeze" ANVIL supplies even after the Operation was in doubt.

Devers, the primary mover and proponent of ANVIL, got his long-awaited opportunity to lead troops in combat. On July 16, with the concurrence of General Marshall and General Eisenhower, General Wilson named him Commander of a newly activated Sixth Army Group made up of Seventh Army and French Army "B". Sixth Army Group Headquarters, covernamed "Advanced Detachment AFHQ", was activated the 29th at Bastia, Corsica. It would serve as a liaison organization between AFHQ, Fifth Army and Seventh Army with no ANVIL operational authority or responsibility. And it would recommend priorities for air and naval support between Allied armies in Italy and those in southern France. General Wilson would retain overall command of ANVIL until the advancing Seventh Army forces driving north up the Rhone River valley from their Riviera beachhead linked up with those from OVERLORD driving eastward. At that time Sixth Army Group under Devers would become operational, reassigned from the MTO to the ETO under General Eisenhower and SHAEF.

ANVIL was renamed DRAGOON by the CCS August 1, 1944. Prime Minister Churchill had suggested the new codename saying he had been "dragooned" into going along with it. Field Order No. 1 issued August 5 instructed Seventh Army under General Patch to launch the often-delayed Operation.

France and Germany 1944-1945[edit]

In September 1944, Devers assumed command of the 6th Army Group which included General Alexander Patch's 7th Army and the French 1st Army of General Jean de Lattre de Tassigny. The later force was the largest French Force ever amassed under any foreign military leader.

Devers' Allied forces helped create a diversionary invasion of Southern France seventy days after the Normandy invasion. Their successes provided the vital supply and relief forces needed to bolster the Allied push into Germany in March 1945.[3]

Retirement and post-military career[edit]

After the war, Devers commanded the Army Ground Forces which was re-designated as Army Field Forces in 1948.

Devers retired in September, 1949. He subsequently began a business career as assistant to the president of Fairchild Aircraft.

From 1960 to 1969 Devers was chairman of the American Battle Monuments Commission.

Death and burial[edit]

In his later years Devers resided in the Washington, D.C. area. He died in Washington on October 15, 1979, and was buried at Arlington National Cemetery, Section 1, Site 149-F.
