I say, Smashing good patrol wot ? Our 3 a/c section was doing a bombardment over Bertaincourt AF. When I spotted 3 e/a in a V formation so I scooted on over. They must have been looking ahead because I was able to fly under and in front of their # 3. My Back Seater fired off 68 rds and got the motor or and Oil line Black smoke everywhere the he slanted left and nosed down for Hunland. By then we were totally lost so crossed and landed at a friendly AF for directions home.
