That's weird, but mostly correct! My maternal Grandfather, having emigrated to Canada in 1913, returned to England in 1915 to enter the war.
He told me that he didn't know if he was going to fight the 'Huns' or the 'Frogs', and that it didn't matter - he didn't like either of them!
His exploits in the war were memorable. Upon dis-embarking in France, he was pushed off the gangplank, broke his leg, and the same ship took him back to Old-Blighty.
He got a large medal for serving ..................................................... FRegards
