The third 'USS ''Hancock'' (AP-3)' was built in 1879 by J. Elder & Co.,
Glasgow,
Scotland. Formerly ''Arizona'', she was purchased by the
War Department during the
Spanish-American War and transferred to the Navy
8 November 1902. She was commissioned
20 November 1902, Lt. Comdr. F. W. Coffin, USN, in command.
''Hancock'' sailed from
San Francisco for the East Coast 14 December 1902 via
Valparaiso,
Chile;
Montevideo,
Uruguay; and
Bahia,
Brazil. She arrived
New York Navy Yard 21 February 1903 and decommissioned 9 March for fitting out. Recommissioned 21 September, she served as receiving ship at the New York Navy Yard until relieved by Washington
6 August 1913.
''Hancock'' departed New York 15 September and arrived at the
Philadelphia Navy Yard the following day to be fitted out as a
Marine transport. She sailed for the
Gulf of Mexico 4 January 1914 having embarked the 1st Regiment, Advance Base Brigade of Marines. She landed the Marines at
Vera Cruz,
Mexico, to assist in the occupation of that city resulting from the arrest of the crew of a whaleboat of
''Dolphin'' (PG-24) by soldiers of
General Huerta, aspirant to the Mexican presidency. During the tense months that followed, ''Hancock'' transported refugees uprooted by the
Mexican Revolution between the coast of Mexico and
Galveston, Texas, as she delivered supplies for the United States Expeditionary Force in Mexico. Other trouble spots erupted in the Americas. Both
Haiti and the
Dominican Republic were going through a series of violent revolutions endangering the lives and property of foreigners and inviting foreign intervention. This situation demanded a buildup of American strength in the area. As a result as the diplomatic crisis with Mexico eased, ''Hancock'' embarked a battalion of Marines from Vera Cruz and transported them to
Guantanamo,
Cuba. She returned to
Norfolk 25 July 1914 to embark the
5th Marine Regiment and got underway 30 July to cruise in waters off Haiti and
Santo Domingo to be on hand to protect American interests against any eventuality. She returned to Norfolk 23 December for a general overhaul.
''Hancock'' resumed duty cruising in the
Caribbean. She continued to transport Marines, stores, provisions, mail, and other cargo to forces ashore in Mexico, Haiti, and Santo Domingo. From 12 to
30 September 1916 she assisted in the salvage of material from
''Memphis'' (CA-10) after the cruiser was driven ashore by a tidal wave in the harbor of Santo Domingo. ''Hancock'' carried the ill-fated ship's crew, stores, fittings, and ammunition to the
Norfolk Navy Yard.
''Hancock'' was at
Guantanamo Bay 27 March 1917 when ordered to proceed to
St. Thomas in the
Danish West Indies, where the Danish Government was to transfer the islands to the United States. She sailed the next day, embarking a Marine Detachment at Santo Domingo before arrival at St. Thomas,
30 March 1917. On 31 March, ''Hancock's'' captain, Comdr.
Edwin T. Pollock, USN, took over the islands in the name of the United States of America. At 1600 when the transfer became effective, Commander Pollock assumed the position of Acting Governor of the Virgin Islands. When the United States declared war on
Germany six days later, Hancock took possession of German steamers ''Wasgenwald'' and ''Calabria'' interned there.
''Hancock'' arrived at
San Juan, Puerto Rico,
18 May 1917 to take possession of two more interned German
steamships, SS ''Praesident'' and ''Odenwald''. She embarked 29 German prisoners of war 23 May, and stood out of San Juan harbor that afternoon to tow ''Odenwald'' to the
Philadelphia Navy Yard where she arrived 1 June.
''Hancock'' was assigned to the U.S. Cruiser and Transport Force to embark troops of the
1st American Expeditionary Force 13 June. She got underway 17 June as
Flagship of Troop Convoy Number 4 and arrived without mishap at
St. Nazaire,
France, 2 July. Returning to Philadelphia 22 July, her principal service until September 1919 was transportation of Marine passengers and military stores to ports in the
West Indies and the
Gulf of Mexico. She returned to Philadelphia 3 September and decommissioned
18 October 1919.
''Hancock'' recommissioned
15 March 1920 and departed Philadelphia 2 April for
Rosyth,
Scotland, to man and fit out former German warships
SMS ''Ostfriesland'' and
''Frankfurt'' which had been allocated to the United States as spoils of war. She returned to New York with the vessels 9 August. After repairs at Philadelphia, she resumed transport duties between the East coast and the West Indies,
5 October 1920. She got underway from Philadelphia
5 March 1921 for
Mare Island,
California, and entered
San Francisco Bay 20 April. The ship then sailed for the
Hawaiian Islands 5 May arriving
Honolulu 14 May, and served as
receiving ship at
Pearl Harbor until 1925. She was towed from Pearl Harbor 9 July 1925 arrived at the
Mare Island Navy Yard 25 July, placed out of commission 1 September 1925, struck from the
Navy List and sold
21 May 1926.
