At the beginning of World War I the ship was in New York and was interned by the United States. She was seized when that country entered the conflict in 1917 and converted to a troop transport. As the USS Pocohantas, she carried 24,573 servicemen to Europe, and after the war returned 23,296 servicemen to the United States. Decommissioned by the US Navy, the United States Shipping Board sold her back to the North German Lloyd line, where she saw mercantile service until being broken up in 1932.
