Posted to Escort a Dfw on a Recon mission. Our flight had 5 of the 8 pilots left in the Jasta and all the fuel since none has come up from the rear area. Over the lines, we spotted a flight of camels high and coming down. I flew over and warned the 2 Seat to flee. However , I was low and slow so missed the fight. The flight claimed 1 destroyed for 1 lost and 2 damaged by enemy fire.
