Oreo I’m not insinuating they were trucked up costly sage, nor that they didn’t take part in combat, but like others, I did wonder why they were sent to England en masse rather than on the front line with us and our other allies?
The answer to your question, is no, I don’t know how many were killed whilst over here. But I can google and easily discover this.
For the obvious reason that by then, Britain was the only country in Europe that wasn't occupied by enemy forces.
Where the USA could land, refuel and re-arm its bomber planes.
Where the US could safely land its troop carrier planes, offload American troops then train them
in how to be landed into an enemy occupied country ( by
sea from a boat, or from a plane by parachute.)
They couldn't fly bombers from USA across 3000 miles of atlantic, bomb Germany, and have enough fuel to fly back to USA.
