Remarks: Our 5 a/c were on patrol at 1500 meters, I sighted 3 machines off to the right going in and out of clouds. Fired off 7 rds to alert the flight. As the closest a/c I led the climbing turning attack. Fired off a drum and swung right to reload. Spotted Maj Hawker close to e/a heard firing then saw the e/a spin into the ground. About the same time Cpt Knight got his machine too. I saw it spin in. The e/a Mono plane had turn ed and flew off. The flight landed with 2 lt damaged and 1 a/c missing.
