Johnson exited the melee and was then immediately attacked by three Bf 109s. The closest was 100 yards away. Maintaining a steep, tight, spiralling turn, he dived into cloud and immediately headed for Dover. Coming out of the cloud, Johnson saw a lone Bf 109. Suspecting it to be one of the three that had chased him, he searched for the other two. Seeing nothing, Johnson attacked and shot it down. It was his fourth victory. Johnson ended his month's tally by adding a probable victory on 21 August. But it had been a bad day and month for the Wing. The much loathed Circus and Rhubarb raids had cost Fighter Command 108 fighters. The Germans lost just 18. On 4 September 1941 Johnson was promoted to flight lieutenant and awarded the Distinguished Flying Cross (DFC).
