What a waste. My Kette of 4 a/c was to target cover / Ground attacker's for 4 He 111's bombing some kind of tall towers at the limit of our range. Over the Area we circled at 18000 as the He 111's came in. I was Bingo on fuel so headed back on less power ,but slanting down to maintain speed. I did notice 3 e/a low going inland,but low on fuel I kept headed for France. I landed at the 1st AF as I was down to 18 % Fuel. The other 3 a/c never came back. Fuel ? Flack ? E/a ?.
