Sometimes, to understand the present you have to eavesdrop on the past. Men and women from the U.S. Army’s 318th psychological operations unit based at Jefferson Barracks spent Sunday morning listening to 80-year-old Ben Fainer turn the pages of his life story. Fainer was a young boy in Poland when Hitler’s Nazis invaded in 1939. “When they came in, I was a little less than 9 years old and they rounded up all the jews is a day or two, ” recalls Fainer. He was immediately separated from his family. He and his father were sent to a hard labor camp while his mother, brother and two sisters were sent to the Auschwitz death camp. Though just 9, he had to grow up fast.
