These were great propaganda raids which—much as the Doolittle Raid on the Japanese home islands had done for boosting American morale in April 1942—were a severe embarrassment for the German leadership. April 20, 1943 was Hitler's 54th birthday. Bomber Command decided that they had to mark the occasion with a raid on Berlin, and it was decided that the Mosquito was the right aircraft for the job. Accordingly, No. 105 Squadron was dispatched to the German capital, successfully reaching the city with the loss of only one aircraft. The first raid of the battle occurred on November 18–19, 1943. Berlin was the main target, and was attacked by 440 Avro Lancasters aided by four Mosquitos. The city was under cloud and the damage was not severe. The second major raid was on the night of November 22–23, 1943. This was the most effective raid by the RAF on Berlin. The raid caused extensive damage to the residential areas west of the centre, Tiergarten and Charlottenburg, Schöneberg and Spandau. Because of the dry weather conditions, several firestorms ignited.

On February 15–16, important war industries were hit, including the large Siemensstadt area, with the centre and south-western districts sustaining most of the damage.

The November 22, 1943 raid killed 2,000 Berliners and rendered 175,000 homeless. The following night, 1,000 were killed and 100,000 made homeless. During December and January regular raids killed hundreds of people each night and rendered between 20,000 and 80,000 homeless each time. Overall nearly
