Switzerland During The World Wars - World War II

World War II

At the outbreak of World War II in 1939, Switzerland immediately began to mobilize for a possible invasion. The entire country was fully mobilized in only three days. The Swiss government began to fortify positions throughout the country. The total strength of the army and militias grew to exactly 498,327 men.

In the course of the war, detailed invasion plans were drawn up by the German military command, such as Operation Tannenbaum, but Switzerland was never attacked. Switzerland was able to remain independent through a combination of military deterrence, economic concessions to Germany, and good fortune as larger events during the war delayed an invasion. Attempts by Switzerland's small Nazi party to affect an Anschluss with Germany failed miserably, largely as a result of Switzerland's multicultural heritage, strong sense of national identity, and long tradition of direct democracy and civil liberties. The Swiss press vigorously criticized the Third Reich, often infuriating its leadership. In turn, Berlin denounced Switzerland as a medieval rudiment and its people renegade Germans. Under General Henri Guisan, a massive mobilization of militia forces was ordered. The Swiss military strategy was changed from one of static defence at the borders, to a strategy of organized long-term attrition and withdrawal to strong, well-stockpiled positions high in the Alps known as the National Redoubt. This controversial strategy was essentially one of deterrence. The idea was to cause huge losses to German forces and render the cost of invading too high. During an invasion, the Swiss Army would cede control of the economic heartland and population centres, but retain control of crucial rail links and passes in the National Redoubt.

Switzerland was an important base for espionage by both sides in the conflict and often mediated communications between the Axis and Allied powers by serving as a protecting power.

Despite the prevailing public and political attitudes in Switzerland, some higher-ranking officers within the Swiss Army had pro-Nazi sympathies: notably Colonel Arthur Fonjallaz and Colonel Eugen Bircher, who led the Schweizerischer Vaterländischer Verband. In Letters with Suzanne (French: Lettres à Suzanne, Lausanne, Switzerland, 1949), the Swiss journalist Léon Savary retrospectively denounced in this sense "the unconscious influence of hitlerism on Swiss people".

Nazi Germany repeatedly violated Swiss airspace. During the Invasion of France, German aircraft violated Swiss airspace at least 197 times. In several air incidents, the Swiss (ironically using 10 Bf-109 D, 80 Bf-109 E fighters bought from Germany prior to the war and some Morane-Saulnier M.S.406s built under license in Switzerland), shot down 11 Luftwaffe planes between 10 May 1940 and 17 June 1940. Germany protested diplomatically on 5 June 1940, and with a second note on 19 June 1940 which contained clear threats. Hitler was especially furious when he saw that German equipment was shooting down German pilots. He said they would respond "in another manner". On 20 June 1940, the Swiss air force was ordered to stop intercepting planes violating Swiss airspace. Swiss fighters began instead to force intruding aircraft to land at Swiss airfields. Anti-aircraft units still operated. Later, Hitler and Hermann Göring sent saboteurs to destroy Swiss airfields, but the sabotage team was captured by the Swiss army before it could cause any damage.

Allied aircraft also intruded on Swiss airspace during the war, mostly Allied bombers returning from raids over Italy and Germany that had been damaged and whose crews preferred internment by the Swiss to becoming prisoners of war. Over a hundred Allied aircraft and their crews were interned. They were subsequently put up in various ski resorts that had been emptied from lack of tourists due to the war and held until it ended.

Switzerland, surrounded by Axis-controlled territory, also suffered from Allied bombings during the war; most notably from the accidental bombing of Schaffhausen by American planes on April 1, 1944. It was mistaken for Ludwigshafen am Rhein, a nearby German town, 40 people were killed and over 50 buildings destroyed, among them a group of small factories producing anti-aircraft shells, ball-bearings, and Bf-109 parts for Germany.

The bombing limited much of the leniency the Swiss had shown toward Allied airspace violations. Eventually, the problem became so bad that they declared a zero-tolerance policy for violation by either Axis or Allied aircraft and authorized attacks on American aircraft. Victims of these mistaken bombings were not limited to Swiss civilians, however, but included the often confused American aircrews, shot down by the Swiss fighters as well as several Swiss fighters shot down by American airmen. In February 1945, 18 civilians were killed by Allied bombs dropped over Stein am Rhein, Vals, and Rafz. Arguably the most notorious incident came on March 4, 1945, when both Basel and Zurich were accidentally bombed by Allied aircraft. The attack on Basel's railway station led to the destruction of a passenger train, but no casualties were reported. However, a B-24 Liberator dropped its bomb load over Zürich, destroying two buildings and killing five civilians. The aircraft's crew believed that they were attacking Freiburg in Germany. As John Helmreich points out, Sincock and Balides, in choosing a target of opportunity, "...missed the marshalling yard they were aiming for, missed the city they were aiming for, and even missed the country they were aiming for."

The Swiss, although somewhat skeptical, reacted by treating these violations of their neutrality as "accidents". The United States was warned that single aircraft would be forced down, and their crews would still be allowed to seek refuge, while bomber formations in violation of airspace would be intercepted. While American politicians and diplomats tried to minimize the political damage caused by these incidents, others took a more hostile view. Some senior commanders argued that, as Switzerland was "full of German sympathizers", it deserved to be bombed. General Henry H. Arnold, Commanding General of the U.S. Army Air Forces, even suggested that it was the Germans themselves who were flying captured Allied planes over Switzerland in an attempt to gain a propaganda victory. However the U.S. eventually apologized for the violations.

Danger from U.S. bombers came not only from accidental bombings, but from the aircraft themselves. In many cases, once a crippled bomber reached Switzerland and was out of enemy territory crews would often bail out, leaving the aircraft to continue until it crashed.

As a neutral state near Germany, Switzerland was easy to reach for refugees from the Nazis. However, Switzerland's refugee laws, especially with respect to Jews fleeing Germany, were strict and have caused controversy since the end of World War II. From 1933 until 1944 asylum for refugees could only be granted to those who were under personal threat owing to their political activities only; it did not include those who were under threat due to race, religion or ethnicity. On the basis of this definition, Switzerland granted asylum to only 644 people between 1933 and 1945; of these, 252 cases were admitted during the war. All other refugees were admitted by the individual cantons and were granted different permits, including a "tolerance permit" that allowed them to live in the canton but not to work. Over the course of the war, Switzerland interned 300,000 refugees. Of these, 104,000 were foreign troops interned according to the Rights and Duties of Neutral Powers outlined in the Hague Conventions. The rest were foreign civilians and were either interned or granted tolerance or residence permits by the cantonal authorities. Refugees were not allowed to hold jobs. Of the refugees, 60,000 were civilians escaping persecution by the Nazis. Of these, 26,000 to 27,000 were Jews. Between 10,000 and 24,000 Jewish civilian refugees were refused entry. Although Switzerland harboured more Jewish refugees than any other country, these refugees were refused entry on the grounds of already dwindling supplies. Of those refused entry, a Swiss government representative said, "Our little lifeboat is full." At the beginning of the war, Switzerland had a Jewish population of between 18,000 and 28,000 and a total population of about 4 million. By the end of the war, there were over 115,000 refuge-seeking people of all categories in Switzerland, representing the maximum number of refugees at any one time.

Switzerland also acted as a refuge for Allied prisoners of war who escaped, including those from Oflag IV-C (Colditz).
