22 Lancasters were lost, nearly 7% of the Lancaster force. The Mosquitoes were used to drop 'spoof' flares well away from the bombers' route to attract German night fighters.

The raid approached Berlin from the north-east but the marking and bombing were, once again, mostly short of the target. That part of the bombing which did reach Berlin's built-up area fell in residential parts of Charlottenburg and Moabit and in the industrial area called Siemensstadt. Several factories wre hit and suffered serious loss of production and among 'utilities' put out of action were major water and electricity works and one of Berlin's largest breweries. 422 people were listed as killed - 225 civilians, 24 servicemen, 18 men and 2 women of the air-raid services, 123 foreign workers - 92 women and 31 men. 170 further civilians were 'missing'. The Berlin records also mention the deaths of another soldier and 7 'criminal' assistants when the 2 delayed-action bombs on which they were working exploded. The criminals could earn remission of their sentences by volunteering for this work on unexploded and delayed-action bombs.

Minor Operatioins: 32 OTU Wellingtons, 6 Mosquitoes and 6 Halifaxes to an ammunition dump in the Foret de Raismes, near Valenciennes; 44 Stirlings and 12 Halifaxes minelaying off Denmark, in the Frisians and off the Biscay coast; 4 Mosquitoes to Dusseldorf and 7 OUT Whitleys on leaflet raids. 1 Wellington, 1 Stirling and 1 Whitley were lost.

Berlin was attacked by a force of 316 Lancasters, with 4 Mosquitoes as "spoof" markers. The target was ground-marked by Y-type aircraft, the T.Is. mainly W. and N.W. of the aimin point, in an area which had not previously been seriously damaged. Much industrial damage was caused, mostly in the Siemensstadt/Charlottenburg area, including Siemens and Halske A.G. and Siemens Schuchertwerke A.G., electrical engineers, both of which works were severely hit. At least half of the 20 aircraft missing wre shot down by enemy fighters.

The majority of the red T.I.'s appear to have been dropped by the blindmarkers 2 to 5 miles W. to N.W. of the target, but one salvo fell very near the aiming-point and one 2 miles E. The backers-up, which arrived late, probably owin to an inaccurate wind forecast, bombed the red T.I.'s to the W., and a good concentration developed there. The main force, which also arrived late, mainly bombed this concentration, or undershot further W. In consequence most of the bombs fell W. and N.W. of the aiming point, in an area which had not previously been heavily damaged.

Damage was confined almost entirely to the wetern half of the city. Most of the damage appeared to be caused by fire, but several large and many small H.E. incidents were visible.

War industries suffered to a sonsiderable extent. 75% of the buildins of the electro-chemical department of Siemens Schuckertwerks were burnt to the ground, and one-third of the rectifier works of Siemens and Halske was gutted, and much other damage was caused to both works. Many buildings of Askania-Werke A.G. at Mariendorf (one of the foremost manufacturers of optical instruments for aircraft) were destroyed by fire and H.E. In addition at least 40 other electrical and engineering firms were affected, several being totally destroyed.
