The first German attacks began almost immediately and employed different tactics from the morning mission. The lead wing was attacked continuously in head-on attacks by both Messerschmitt Bf 109 and Focke-Wulf Fw 190 fighters, and although the RAF escorts claimed eight victories they were forced to return to base early in the engagement. The two groups of P-47s (88 aircraft) arrived five and eight minutes late, and despite some individual combats, they too were forced to break off virtually as soon as they arrived.
