U.S.S. President Lincoln
Before becoming a transport ship for the Navy in April 1917, the U.S.S. President Lincoln was a German passenger ship of the Hamburg-American line. On May 31, 1918, while returning from her fifth voyage carrying troops to France, the President Lincoln was torpedoed by a German submarine, U-90. She sank in less than half an hour, killing 26 of the more than 700 people on board. One officer, Lieutenant Eduard Isaacs, was captured.
