A bit of info on him:
At this time, another Briton, Thomas Haller Cooper (who used the German version of Cooper – Boettcher – as his last name), arrived at the camp. Cooper, unable to obtain public service employment in Britain due to his mother's German nationality, joined the BUF. During a visit to Germany in 1939, he became trapped there by the war and joined the Waffen-SS. He was posted to the SS Leibstandarte Adolf Hitler (LAH), where he eventually transferred to the infamous SS "Totenkopf" infantry training battalion. He became a machine-gun instructor with the 5th Totenkopf Regiment and was made an NCO. Following the German invasion of the Soviet Union, he was assigned to the Wachbattaillon Oranienburg outside Kraków, Poland, where he allegedly told BFC men that he committed atrocities against Soviet POWs, Polish civilians, and Jewish prisoners. Later, he served as transport driver in the SS-Polizei-Division, which was posted to Schablinov, a town on the Leningrad front, replacing the mangled forces of the Spanish Blue Division. When Soviets attacked the division on 13 February 1943, Cooper was hit in the legs by shell splinters, evacuated, and awarded the Wound Badge in Silver, becoming the only Englishman to obtain a German combat decoration.
