He had learned desperate arts in the Nazi concentration camp, such as how to use maggots to stop the spread of gangrene, [biographer Daniel M.] Cohen said. Cohen said Rubin told him that the POW camp was "a cakewalk" compared with Mauthausen.

Decades later, when the writer reached one of his camp mates on the phone, "the first words out of his mouth were, 'Rubin saved my life,'" Cohen said.

Ted found himself in the Pukchin POW camp, also known as "Death Valley," and later at Pyoktong, along with hundreds of Americans, Turks, and others. The camps were at first run by the North Koreans, then by the Chinese, whom Ted said treated them slightly better. Nevertheless, life was nightmarish for the prisoners. They were cold and hungry, and disease was rampant. "Healthy men became like babies, helpless," Ted said. "Everything was stink, death, it was terrible, terrible." Thirty to forty a day were dying. "It was hardest on the Americans who were not used to this," Ted said. "But I had a heck of a basic training from the Germans."
Ted used all the experience he had gained as a Holocaust survivor in helping keep himself and other prisoners alive. "I did it because I was an American," Ted told me, "and because it was a mitzvah. Regardless of color or nationality, they were my brothers." Food was vital for survival, so he began to steal rations from the enemy, who had little enough themselves. Fellow POW Sergeant Carl McClendon stated, "every day, when it got dark, and we went to sleep, Rubin was on his way, crawling on his stomach, jumping over fences, breaking in supply houses, while the guns were looking down on him. He tied the bottom of his fatigue pants and filled up anything he could get ahold of. He crawled back and distributed the food that he had stolen and risked his life."
