At the beginning of the Second World War, an anti-aircraft position was built on the island of Neuwerk to defend against air attacks and air-supported mine-laying in the mouth of the Elbe. Their positions can be identified on corresponding aerial photographs, and there are also photographs of the northern position, but unfortunately these are not available. The anti-aircraft battery on the island was always referred to in combat reports as l. Flak Neuwerk, which belonged to the 6./ M.FLA.A 214 Cuxhaven. From 1940, the Neuwerk anti-aircraft gun was equipped with two 20 mm Flak 30s. The position was briefly reinforced at the beginning of 1940 by the Hamburg air force battery "von Kuck", but this withdrew after just a few weeks. From July 6, 1940, a 4 cm SK/L 55 was also installed to reinforce it against air attacks. From the end of 1944, the Neuwerk light anti-aircraft gun was also responsible for protecting the construction site of the coastal artillery position "von Stosch". Further deployment of light anti-aircraft guns during the course of the war is likely. Source: MB, G.Wildfang/Cuxhaven.
