On July 22, 1944, with World War II ongoing, Bukowski was arrested by F.B.I. agents in Philadelphia, Pennsylvania, where he lived at the time, on suspicion of draft evasion. At a time when the United States was at war with Germany and many Germans and German-Americans in the United States were suspected of disloyalty, his German birth troubled the US authorities. He was held for 17 days in Philadelphia's Moyamensing Prison. Sixteen days later, he failed a psychological examination that was part of his mandatory military entrance physical test and was given a Selective Service Classification of 4-F (unfit for military service).
