Over Britain... This is Adlertag (Eagle Day) which is to mark the beginning of the all-out Luftwaffe offensive against the RAF. The German objective is to cripple the British defenses and clear the sky over southern England within four days and, then, to eliminate RAF resistance completely within four weeks. The events of Eagle Day go strongly in favor of the RAF. The Germans fly about 1500 sorties, 1000 by fighters, and the British about 700 exclusively by fighters. The Germans lose 45 planes, the British only 13 and from these six pilots are able to return to their units and new machines.
