The German city of Konstanz used lights to trick the Allies into not bombing it during WWII

Air raids were a frequent event during World War II, with cities across Europe facing nighttime bombings intended to catch their military forces off guard. Remarkably, the German city of Konstanz managed to stay relatively untouched by Allied attacks, due to some clever use of lighting.

Konstanz is a historic city

Konstanz is located in southern Germany, in the state of Baden-Württemberg. It sits at the edge of the Swiss Alps, along Lake Constance. Its closest neighbor is the Swiss municipality of Kreuzlingen — in fact, the border between Switzerland and Germany runs right through the city’s center.

Konstanz dates back to the late Stone Age. Its name is believed to have been coined during the Roman Empire, and it was home to a Roman Catholic principality for over 1,200 years. It was also the location of the Council of Constance in the early 1400s, which called for the end to the Great Schism.

The city officially became part of the German Empire in 1871, during the country’s unification. Upon the conclusion of World War I, it existed within the Republic of Baden, which was part of the Weimar Republic.

Air raids during World War II

Also known as strategic bombings, air raids were experienced by many cities within Europe during the Second World War. They targeted key locations, including highly populated cities, transportation hubs and production factories, and aimed to cripple the opposing forces.

These attacks typically occurred at night and were paired with ground forces to ensure the most damage was inflicted. The overall goal was to disrupt the enemy as much as possible. They were fairly effective, and as the war progressed, such bombings occurred with more frequency.

The Germans’ primary focus was England, where they targeted London and port cities. The Allies caused much more damage in Germany, and their air raids decimated such cities as Hamburg and Dresden. This was due to the fact their aircraft were able to carry more bombs than their Luftwaffe counterparts.

Konstanz refuses to go dark

To protect themselves from air raids, many cities enforced nightly blackouts. Residents were prohibited from lighting candles indoors and were instructed to cover their windows with curtains or black paint. Streetlights were turned off, and vehicles were barred from using headlights.

This approach was intended to make it harder for attacking forces to locate and strike their targets. By doing so, essential services and facilities had a better chance of surviving the bombings, and civilian safety was prioritized.

While most German cities followed these blackout measures, Konstanz did not. Instead, it chose to keep its lights on, inspired by its Swiss neighbors in Kreuzlingen, who could remain lit due to the country’s neutrality. The idea was straightforward: by keeping the lights on, they hoped the Allies would assume Konstanz was part of Switzerland.

This strategy proved successful. American pilots flying above mistook Konstanz for a Swiss city and refrained from bombing. As a result, Konstanz preserved much of its original architecture, eventually fostering a flourishing tourism industry in the post-war years.

Konstanz contributed to the war effort in Germany

Looking back, the Allies probably wished they hadn’t been fooled by the tactic, as Konstanz played an active role in the German war effort. The city produced parts for the German arsenal, all of which were used against the Allies.

Konstanz manufactured radar parts for German submarines, as well as for guns. Schwarzwald Flugzeugbau GmbH developed its flying torpedoes at a facility in the city, while aircraft manufacturer Dornier transferred a portion of its production there after the bombing of Friedrichshafen.

As well, Konstanz actively participated in the deportation of Jewish citizens from Germany. In October 1940, the last were sent to the Gurs internment camp in southwestern France. Those still alive in August 1943 are believed to have died at either Auschwitz or Sobibór.
