Arctic convoys

My uncle, my Moms brother served in HMS Diadem on the arctic convoys as a boot neck gunner.
He did three runs.
After the war with his steely eyed 1000 yd stare, he committed armed robbery in Manchester and shot at the old bill who pursued him.
It was offered in mitigation that he and his three oppos who were his accomplices and also ex Diadem had gone OTT because of the horrors of the three journeys.
Judge did not seem to agree and all three were ordered to serve life imprisonment and were finally released in 1962.

They only did one run in Diadem.
