The period that would eventually be designated the Battle of Britain was now drawing to a close. But in late October the Germans were still conducting fighter sweeps across southern England and RAF fighter squadrons were still meeting them. One Spitfire pilot describes how he was detached from his flight to investigate enemy aircraft and then returned to join his colleagues above south East London. Moments later he realised he had mistakenly joined a patrol of enemy Me 109s and was weaving between enemy aircraft:
When I realized what I was doing I got a pretty fair shock. I went in to attack double quick. One Messerschmitt did a barrel roll to the left. I fired at him as he did so, and he dropped back. I was then engaged from astern, and lost a bit of ground. By the time we got to Hastings I had caught up the rest of them again, and knocked bits off one. Another was half a mile or more below and behind the others as they crossed the coast. He was dropping back rapidly, and I was hoping to finish him off when six more Messerschmitt 109’s came down at me from over the Channel in line abreast.
They went into line astern and circled round me at about 30-yards intervals. But number six was about 100 yards behind number five, so I went for him. He climbed steeply in a close turn. I had about 300 miles an hour on the clock, so I pulled up almost vertically and gave him a burst flat into his feet from beneath. He rolled over and went straight down. By this time number one was on my tail, so I went down behind number six, who was still going straight down in a slow aileron turn at 10,000 feet. But number one was still worrying me, so I went into a steep left-hand turn—and blacked out. On recovering from my black-out there were no more enemy in sight, so I climbed up again and went home.
