The successful pilots succeeded because they did not open fire until they were close to the target.
We were all flying around up and down the coast near Dunkirk looking for enemy aircraft which seemed also to be milling around with no particular cohesion.
Like the Spitfire it was immensely strong: a pilot had no need to fear the danger of pulling the wings off, no matter how desperate the situation became.
I then realized my appearance was a bit odd. My right leg was no longer with me. It had caught somewhere in the top of the cockpit as I tried to leave my Spitfire.
The sea from Dunkirk to Dover during these days of the evacuation looked like any coastal road in England on a bank holiday. It was solid with shipping.
