April 1942 – British Air Operations in Europe 

RAF Bomber Command attacks continue to increase in intensity this month. There are also almost daily offensive fighter sweeps over occupied France.

Bomber Command’s range of targets includes industrial areas in Germany and France and several Atlantic ports in France and Norway. Cologne, Hamburg and Rostock are all heavily hit. Rostock was chosen for its easy-to-find position on the Baltic coast. Despite being attacked four times during the month, industry in Rostock is soon back at full production.
