Bombing of Berlin in World War II - Berlin's Defences

Berlin's Defences

The Nazi regime was acutely aware of the political necessity of protecting the Reich capital against devastation from the air. Even before the war, work had begun on an extensive system of public air-raid shelters, but by 1939 only 15% of the planned 2,000 shelters had been built. By 1941, however, the five huge public shelters (Zoo, Anhalt Station, Humboldthain, Friedrichshain and Kleistpark) were complete, offering shelter to 65,000 people. Other shelters were built under government buildings, the best-known being the so-called Führerbunker under the Reich Chancellery building. In addition, many U-Bahn stations were converted into shelters. The rest of the population had to make do with their own cellars.

In 1943, the Germans decided to evacuate non-essential people from Berlin. By 1944 1.2 million people, 790,000 of them women and children, about a quarter of the city's population, had been evacuated to rural areas. An effort was made to evacuate all children from Berlin, but this was resisted by parents, and many evacuees soon made their way back to the city (as was also the case in London in 1940-41). The increasing shortage of manpower as the war dragged on meant that female labour was essential to keep Berlin's war industries going, so the evacuation of all women with children was not possible. At the end of 1944 the city's population began to grow again as refugees fleeing the Red Army's advance in the east began to pour into Berlin. The Ostvertriebene (refugees from the East) were officially denied permission to remain in Berlin for longer than two days and were housed in camps near to the city before being moved on westwards; it is estimated less than 50,000 managed to remain in Berlin. By January 1945 the population was around 2.9 million, although the demands of the German military were such that only 100,000 of these were males aged 18–30. Another 100,000 or so were forced labor, mainly French fremdarbeiter, "foreign workers", and Russian Ostarbeiter "eastern workers".

The key to the Flak area were three huge Flak towers (Flakturm), which provided enormously tough platforms for both searchlights and 128 mm anti-aircraft guns as well as shelters (Hochbunker) for civilians. These towers were at the Berlin Zoo in the Tiergarten, Humboldthain and Friedrichshain. The Flak guns were increasingly manned by the teenagers of the Hitler Youth as older men were drafted to the front. By 1945 the girls of the League of German Girls (BDM) were also operating Flak guns. After 1944 there was little fighter protection from the Luftwaffe, and the Flak defences were increasingly overwhelmed by the scale of the attacks.
