I heard this from an old guy who heard it first hand from a vet, and he thought that it wouldn’t be recorded anywhere. I’m writing it into the ether for posterity, on the off chance a historian finds it in years to come and finds it interesting.
‘They used to carry people back and forth from the front line trenches to the behind lines rest area’s in old London buses. Rather than sit quietly, they would always run up to the top deck, and run from side to side trying to topple the bus”
Whether this was insanity, fun, or a desire to stay on the front line wasn’t explained.
