My dad related this story to me when he was quite old, never said an awful lot about his WW2 days.

He was on the beach at Dunkirk for four days, didn't like the Stukas unsurprisingly. On one of the days him and a buddy were told to take a truck and go to pick up some wounded from a barn a way back from the beach, they had a BrenGun carrier with them. They got there safely although he did say they could see German tanks in the fields on the way.

As the were loading the troops a German armoured car and a motorbike+sidecar with a MG mounted on it came into the farmyard. First shot from the armoured car took out the bren gun, truck took off with the armoured car chasing it and machine gunning the guys in the back. My dad was in the front passenger seat with someone sitting on his lap, that dude got a bullet in the head and was killed outright.

The road they were on had high hedges and they couldn't get off it, eventually they came to a gate and the driver crashed through it....straight into the middle of a squad of German tanks. Luckily the crews were outside of them cooking a meal, drove straight past them to a canal at the edge of the field and jumped into it, dad and his buddy spent the next eight hours up to their necks in the water hiding from the searching Germans and eventually made it back to the beach. Lucky man, survived N.Africa and Monte Cassino afterwards, didn't have a lot to say about that apart from MC being hell on earth.
