GGGG grandfather was a German mercenary employed by the British, American revolution. Not sure how well known it is but....the British hired 30,000 mercenaries to fight in the war.

A number of Indian wars, mostly on the plains, USA and Canada, both sides.

My Grandfather WW1 and WW2, wounded in the 1st, (1st Canadian mounted rifles) nearly died there, he was only 17.
He lived to lie his way into WW2, I have all his discharge papers from both wars.

My uncle was a royal rifle, spent 4 yrs in a Japanese prison camp (hong kong), enough said.
I had a picture of him in the camp, but it was lost in the computer..

My Dad also served and was stationed in Germany after the war.
