Corinto, Nicaragua
From 13 December 1909 to 27 March 1910, "Yorktown" operated off Corinto, Nicaragua, with the Nicaraguan Expeditionary Squadron. She then pursued a schedule of exercises and maneuvers, operating between California and British Columbia through June and July. She returned to a posture of readiness off Corinto and San Juan del Sur between 13 August and 7 September. She then operated off Ecuadorian, Colombian, and Peruvian ports, with the United States Consul General at Large embarked, between 19 September and 16 October before putting into Panama for coal and stores. She subsequently patrolled at Amapala, Honduras, and the familiar Corinto for most of November and December. She spent Christmas at Corinto before shifting to Amapala, en route to San Francisco and Mare Island. From March to July 1911, "Yorktown" cruised off the west coasts of Mexico, 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.
