SS Prinz Eitel Friedrich was a

auxiliary cruiser of the Imperial German Navy. Though largely overlooked, Prinz Eitel Friedrich was, after SS Kronprinz Wilhelm
, the most successful of Germany’s first wave of auxiliary cruisers. She was able to remain at large for seven months, from August 1914 to March 1915, and sank 11 ships, for a total tonnage of 33,000 GRT.

Early career

Prinz Eitel Friedrich was built for the

Stettin, in 1904. For the ten years prior to the First World War she served on NDL routes in the Far East. On the eve of war in August 1914 she was at Shanghai, with orders to proceed to the German naval base at Qingdao for conversion as an auxiliary cruiser (Hilfskreuzer).[2]

Service history

At Qingdao Prinz Eitel Friedrich was equipped for her role as a

commerce raider, receiving the armaments and crews of the aging gunboats Luchs, and Tiger. KK
Max Therichens, of Luchs, took command.

She was commissioned on 5 August 1914 and sailed from Qingdao the same day to join company with

, and Prinz Eitel Friedrich arrived there on 12 August.

On 13 August she was detached for independent operations with a remit to attack and destroy allied commerce. She sailed south to start this mission along the coast of Australia.[2]: 72 

In the following seven months she operated in the

South Atlantic, sinking 11 vessels, mostly sailing ships, for a total of 33,423 gross register tons

In March 1915, with her bunkers nearly empty and her engines worn out, Prinz Eitel Friedrich headed for the neutral United States, and on 11 March 1915 sailed into Newport News harbour.[2]: 82

Internment and United States flag

Prinz Eitel Friedrich failed to leave the neutral port in the time prescribed by international law and was interned on 9 April 1915. The ship, still under the German flag, was moved to the

Philadelphia Navy Yard where, upon the United States declaration of war with Germany on 6 April 1917, she was seized by U.S. Customs officials and then transferred to the Navy.[5]

U.S. Naval service

Reconditioned and refitted as a troop transport and given the identification number (Id.No.) 3010, she was renamed and commissioned USS DeKalb (ID-3010) at the Philadelphia Navy Yard on 12 May 1917. DeKalb served for the remainder of the war as a troopship on the trans Atlantic route.[5]

Immigrant ship

The ship was acquired by

United American Line of New York.[7] Mount Clay made the initial voyage as an immigrant ship on Christmas Day 1920 (Marine Review) or 26 December (DANFS).[6][5]

Mount Clay made the last westbound voyage from Hamburg to New York on 15 October 1925 and was laid up until scrapped in 1934.[5]
