Escort an American daylight bomber group toward the trainworks at Mainz, Germany as part of the new long-range strategic bombing campaign against distant military and industrial targets. Travel as far as your fuel will allow. Enter combat only with enemy aircraft that pose a direct threat to the bombers. Because you lack sufficient range, your fighters must break off and return to base before the bombers reach the target. The bombers are heavily armed, however, and the Americans claim that they should be able to defend themselves.
You have four Spitfire IXe fighters under your command. You will escort six B-17 Flying Fortress heavy bombers.
