Bomber Command Losses Vol 5. W R. Chorley.

From the Bomber Command War Diaries:

28/29 January 1944

Berlin: 677 aircraft - 432 Lancasters, 241 Halifaxes, 4 Mosquitos. Part of the German fighter force was drawn up by the early diversions and the bomber approach route over Northern Denmark proved too distant for some of the other German fighters. The German controller was, however, able to concentrate his fighters over the target and many aircraft were shot down there. 46 aircraft - 26 Halifaxes, 20 Lancasters - lost, 6.8 per cent of the force. The cloud over Berlin was broken and some ground-marking was possible but the Bomber Command claim that this was the most concentrated attack of this period is not quite fully confirmed by German records. The western and southern districts were hit but so too were 77 places outside the city.

Hope this helps
