WWII German "OST" Sleeve Patch-This was worn by forced labor workers from the east. The Ostarbeiter were the Eastern workers, primarily from Reichskommissariat Ukraine. They were marked with a badge reading "OST" (East, similar to Poles from Kresy) and were subject to even harsher conditions than the civilian workers. They were forced to live in special camps that were fenced with barbed wire and under guard, and were particularly exposed to the arbitrariness of the Gestapo and the commercial industrial plant guards. At the end of the war 5.5 million Ostarbeiter were returned to the USSR. This printed square patch has blue outlined. There is some discoloration and what looks like a few burn marks. Scarce!
