Zuiderdijk was in commercial operation with the Holland-America Line in 1918 when the need of the United States for ships to transport men & material to the front in Europe during World War 1 forced seizure of Dutch ships in American ports. Customs officials at San Juan, Puerto Rico, took possession of the vessel on 21 March 1918 & turned her over to the US Navy, which placed her in commission on 23 March 1918 under Lieutenant W. F. Reefer USNRF. On 21 July 1919 she was decommissioned & returned to her former owners.
June 1940 Edera was laid up La Coruna. In December 1943 she was requistioned by the Italian Government for Allied service.
