Fireworks today. I was posted as acting flight commander on a 2 a/c Arty spot. We had just finished up and spotted 2 Hun Recon machines. Bang up little fight, we did a lot of slow turns in front of the Huns as our gunners banged away. the followed one Hun down towards his side. His prop stopped and was last seen gliding off to Hunland. On the bad side, We had to cross the lines at 300 meters took 3 hits in the wing and another that killed my gunner. Put down at friendly airfield. Ammo Rpt: Lewis Gun empty. Wing man a/c shot off 62 rds.
