Fighter Command suffered badly in 1941. Losses were about 2 percent aircraft per sortie while 2 Group Bomber Command suffered 7.68 percent casualties. From 14 June 1941, Fighter Command reported 411 fighters over the Channel; 14 on the last "Circus" of the year. The British claimed 731 German aircraft destroyed though only 103 German fighters were lost. A post-war survey concluded by the Air Ministry asserted that the RAF lost 2.5 pilots for every German fighter downed. The German "geschwader", in contrast, destroyed four for every one they lost. Their percent remained at one percent. Among the most successful pilots to emerge were Josef Priller, who claimed 19 in 26 days from 16 June. On 5 December 1941 Galland was appointed "General der Jagdflieger" after the death of Mölders. Schöpfel replaced him.
