Harris was awarded the American Legion of Merit on 30 January 1945. The most controversial raid of the war took place in the late evening of 13 February 1945. The bombing of Dresden by the RAF and USAAF resulting in a lethal firestorm which killed a large number of civilians. Estimates vary but the city authorities at the time estimated no more than 25,000 victims, a figure which subsequent investigations, including one commissioned by the city council in 2010, support. Raids such as that on Pforzheim late in the war as Germany was falling have been criticised for causing high civilian casualties for little apparent military value. The culmination of Bomber Command's offensive occurred in March 1945 when the RAF dropped the highest monthly weight of ordnance in the entire war. The last raid on Berlin took place on the night of 21/22 April, just before the Soviets entered the city centre. After that, most of the rest of the attacks made by the RAF were tactical missions. The last big strategic raid was the destruction of the oil refinery in Tønsberg in southern Norway by a large group of Lancasters on the night of 25/26 April.
