A national redoubt or national fortress is a general term for an area to which the (remnant) forces of a nation can be withdrawn if the main battle has been lost—or even beforehand if defeat is considered inevitable. Typically a region is chosen with a geography favouring defence, such as a mountainous area or a peninsula, in order to function as a final hold-out to preserve national independence and host an effective resistance movement for the duration of the conflict.

Western Europe[edit]


In 1940 Brittany was briefly considered as such in the last stages of the Fall of France, but proved impractical.

In 1944, at the opposite corner of l'Hexagone, there was an attempt to jumpstart the liberation by Free French Maquis du Vercors establishing a "Free Republic" on the Vercors Plateau.


Major Dutch defence lines in 1940

Until 1920, the "Fortress Amsterdam" was that of the Netherlands. Between 1920 and 1940 Fortress Amsterdam was extended to Fortress Holland, to include a larger part of the country's heartland. In neither case did any "redoubt" prove defensible — even though the Dutch Water Line, a precursor in the Netherlands, did manage to stop the advances of the French troops in the Rampjaar 1672, providing the Dutch with much-needed time to eventually gain the upper hand.


From the middle of the 19th century until 1914 the fortress city of Antwerp was the official National Redoubt of Antwerp in Belgium.

Fortress Antwerp was a defensive belt of fortifications built in two rings to defend Antwerp. Antwerp was designated to be a national reduit (Réduit national (French) or De versterkte stelling Antwerpen (Dutch)) in case Belgium was attacked. It was built in the period 1859–1914. In total it encompasses a belt of fortifications of 95 km.

German-speaking Europe[edit]


The Alpine Fortress (German: Alpenfestung) was the World War II national redoubt planned by Heinrich Himmler in November/December 1943[a] for Germany's government and armed forces to retreat to an area from "southern Bavaria across western Austria to northern Italy".[b] The plan was never fully endorsed by Hitler and no serious attempt was made to put the plan into operation.

In the six months following the D-Day landings in Normandy in June 1944, the American and British armies advanced to the Rhine and seemed poised to strike into the heart of Germany, while the Soviet Army, advancing from the east through Poland, reached the Oder. It seemed likely that Berlin would soon fall and Germany be cut in half. In these circumstances, it occurred both to some leading figures in the German regime and to the Allies that the logical thing for the Germans to do would be to move the government to the mountainous areas of southern Germany and Austria, where a relatively small number of determined troops could hold out for some time.

A number of intelligence reports to the Supreme Headquarters of the Allied Expeditionary Forces (SHAEF) identified the area held stores of foodstuffs and military supplies built up over the preceding six months, and could even be harbouring armaments production facilities. Within this fortified terrain, they said, Hitler would be able to evade the Allies and cause tremendous difficulties for the occupying Allied forces throughout Germany.

The final operations of the Western Allied armies in Germany between 19 April and 7 May 1945

The Nazi Germany minister for propaganda, Joseph Goebbels, set up a special unit to invent and spread rumours about an Alpenfestung. Goebbels also sent out rumours to neutral governments, thus keeping the Redoubt myth alive and its state of readiness unclear. He enlisted the assistance of the intelligence service of the SS, the SD, to produce faked blueprints and reports on construction supplies, armament production and troop transfers to the Redoubt. This successful and utter deception of allied military intelligence is considered to be one of the greatest feats of the German Abwehr during the entire war.

Although Adolf Hitler never endorsed the plan, he issued an order on 24 April 1945 for the evacuation of remaining government personnel from Berlin to the Redoubt; he made it clear that he would not leave Berlin himself, even if it fell to the Soviets, as it did on 2 May 1945 (see Battle of Berlin). When the American armies penetrated Bavaria and western Austria at the end of April, they met little serious resistance, and the National Redoubt was shown to have been a myth.[1]

Nevertheless the National Redoubt had serious military and political consequences. Once the Anglo-American armies had crossed the Rhine and advanced into western Germany, they had to decide whether to advance on a narrow front towards Berlin, or on a broad front, with a view to securing both the North Sea coast and southern Germany before advancing further. The American commander of the southern force, General George S. Patton, had consistently advocated a narrow front ever since D-Day,[c] and did so again at this point. But the Allied commander in chief, U.S. General Dwight Eisenhower, took a more cautious view, and the broad front strategy prevailed.

Goebbels' deception plan over the Redoubt was one of the great successes of German intelligence during World War II, albeit one that came too late to alter the outcome of the war. The Allied intelligence services were completely fooled by Goebbels' false trail of rumours.

The Alpine Fortress was one of three reasons associated with SHAEF's movement of forces towards southern Germany rather than towards Berlin (cf. Berlin was planned to be in the Soviet Zone of Occupation and the Battle of Berlin would entail unacceptably high Western Allied casualties).

Evacuations to the Alpine Fortress[edit]

  • February/early March 1945, SHAEF received reports that German military, government and Nazi Party offices and their staffs were leaving Berlin for the area around Berchtesgaden, the site of Hitler's retreat in the Bavarian Alps.
  • In February 1945, the SS evacuated V-2 rocket scientists from the Peenemünde Army Research Center to the Alpine Fortress.
  • SS Generalleutnant Gottlob Berger claimed Hitler had signed a 22 April 1945 order to evacuate 35,000 prisoners to the Alpine Fortress as hostages, but Berger did not carry out the order[2] (many evacuated locations also failed to obey Hitler's order requiring Demolitions on Reich Territory, e.g., Mittelwerk).

Post-war claims[edit]

Post-war claims regarding the Alpine Fortress include:

  • The Alpine Fortress "grew into so exaggerated a scheme that I am astonished we could have believed it as innocently as we did. But while it persisted, this legend of the Redoubt was too ominous a threat to be ignored." (General Omar Bradley)[3]
  • Allied assessments of the Alpine Fortress were "the worst intelligence reports of all time, but no one knew that in March of 1945, and few even suspected it." (author Stephen E. Ambrose)[4]


Plan of the Defence lines of the Swiss National Redoubt

Swiss National Redoubt (Schweizer Alpenfestung or Réduit suisse) was a defensive plan developed by the Swiss government during World War II to respond to a possible German invasion, which had been planned but was never carried out.

The plan was in three stages: first, to hold an invading army on the border; second, if that failed, to launch a delaying war that would allow the bulk of Swiss forces to withdraw to a defensible perimeter in the Swiss Alps; and third, to defend that mountain stronghold.[5]


During the Cold War, Austria developed a similar plan called Raumverteidigung (area defence). The plan was primarily directed against Hungary and Czechoslovakia (and later the Warsaw Pact) but it also included plans against an attack by NATO forces. The Austrian Armed Forces would retreat into key zones situated in the alpine region and defend it. They would also employ guerilla warfare behind enemy lines and delay the enemy advance in the area's security zones.[6][7]

Other regions[edit]


The Chinese Nationalists relocated to the island of Taiwan after the Civil War.

During the Second Sino-Japanese War in World War II, the city of Kunming was prepared as a national redoubt in case the temporary capital in Chongqing fell, an elaborate system of underground caves to serve as offices, barracks and factories was prepared but never utilized.

Kunming was again to have served in this role in the renewed Chinese civil war, but the Nationalist garrison changed sides and joined the Communists. Instead, Taiwan became the last redoubt and home of the Nationalist government, a role which continues to this day.[8]


According to the "Total National Resistance" defense doctrine of the second Yugoslavia, a rugged highland area focused on central Bosnia (roughly, the Lašva Valley) was to function as a redoubt to which the Yugoslav People's Army would retreat in case of a Soviet or NATO invasion. Defense of the rest of the country was to be left to the guerrilla-warfare efforts of the Territorial Defense forces. A network of industrial zones and fortified bases was developed in anticipation, including factories in boom cities like Zenica and an underground air force base at Željava and a command bunker complex intended for the use of Marshal Josip Broz Tito.

Palestine / Israel[edit]

As Nazi Afrika Korps forces proceeded eastward towards Egypt in World War II, the Jewish community in Palestine considered retreating into fortified positions at Haifa and the Mount Carmel region, were the Nazi advance to reach them. The Palestine Post Occupation Scheme was a short-lived 1942 collaboration between the Jewish underground Palmach and the British Special Operations Executive, with training for the plan centered at the kibbutz Mishmar HaEmek, and Moshe Dayan to be put in charge of managing a clandestine radio network.

In Jewish underground circles, the plan was also variously called the "Plan for the North", "Masada on the Carmel", "Haifa-Tobruk", "Haifa-Masada-Musa-Dagh", or "Haifa Stronghold". The planners on the Palmach side were Yohanan Ratner and Yitzhak Sadeh. David Shaltiel (commander in Haifa at the time) and Yitzhak Gruenbaum were vocal supporters of a Masada-like stand, while Yigal Allon and others were skeptical of its usefulness. The evacuation of women and children to Cyprus was also considered.

The decisive British victory at the Second Battle of El Alamein soon afterward rendered the plan moot.


During the 1930s and 1940s, assuming that Poland was only attacked by the Germans, the Polish forces were to make the last stand in the area of the Romanian Bridgehead. After the Battle of Bzura was over and even after the Soviet invasion of Poland, many Polish divisions kept on heading towards the Romanian Bridgehead. Mr. Colonel/Minister Beck's proposal to establish Lviv as the temporary capital of Poland, in the case of the German attack, was rejected; possibly because Lviv was west from the very bridgehead.
