She then returned home by way of Suez Canal and Mediterranean ports reached Boston 17 September 1920, and became a unit of the Special Service Squadron watching over American interests in waters ranging to the Panama Canal and down the West Coast of the Central American States to Corinto, Nicaragua. On 8 August 1921 she was reclassified CL-19. She also intermittently patrolled in the Gulf of Mexico with periodic calls at ports of Florida, Texas, Alabama, and Louisiana.
