Nicaragua, and Honduras. On 29 May, she rescued the survivors from the foundered Panamanian steamer , which had sunk with the loss of 60 of its 100 passengers and crew. Another period of repairs and upkeep in the late summer of 1911 proceeded the ship's duties off the Pacific coasts of South and Central America. She returned to Mare Island in May 1912, and was decommissioned there for alterations on 15 July. 1913–1919 Recommissioned on 1 April 1913, with Commander George B. Bradshaw in command, Yorktown operated out of San Diego on shakedown into mid-April. She was soon back at Corinto, however, remaining in Nicaragua until 5 June. After a brief period of operations off the coast, she returned to Corinto on 21 June and remained there for over a month before departing on 31 July to coal at Salina Cruz, Mexico. She moved to Mazatlán on 10 August and there picked up mail, delivering it to the port of Topolobampo, Mexico, on the 11th. Yorktown remained there until mid-September. For the remainder of 1913, Yorktown conducted local operations out of San Diego and San Francisco. In January 1914, though, the gunboat returned to Mexican waters and investigated local conditions at Ensenada between 3 and 6 January before moving, in subsequent months, to a succession of Mexican ports: Mazatlán, San Blas, Miramar, Topolobampo, and La Paz. Following an overhaul at Mare Island from 24 June to 2 September 1914, Yorktown served in Mexican waters again into June 1915. From that point until the entry of the United States into World War I in April 1917, Yorktown continued her routine of patrols off Mexican, Nicaraguan, and Honduran ports with occasional repairs at Mare Island and maneuvers out of San Diego. After the United States joined the Allies, Yorktown operated off the coast of Mexico until August 1917, when she paused briefly at San Diego. On 18 July 1917, Yorktown rescued the last surviving members of an abandoned guano mining settlement on Clipperton Island. From a peak population of roughly 100 in 1915, only four women and seven children survived. After her time off the Mexican coast, Yorktown then cruised off the west coasts of Central and South America into 1918. After a refit at Mare Island, Yorktown, sailed for the east coast on 28 April 1918, transiting the Panama Canal en route, and arrived at New York on 20 August. The
