East Coast operations
Pacific Ocean deployment
For the next three years, she sailed out of San Diego and San Diego, California, carrying supplies, provisions and passengers along the California coast, and towing lighters, targets, and disabled ships. Cardinal was redesignated as AM-6 on 17 July 1920.
From 8 February – 16 April 1923, Cardinal sailed to the Panama Canal to provide tug services during fleet battle practice. She returned to San Pedro to prepare for duty in Alaskan waters, and on 23 May sailed for Port Angeles, Washington, where she called from 30 May – 1 June.
While bound for Dutch Harbor on 6 June, she was grounded on a reef off the east coast of Chirikof Island, and heavy flooding began immediately. Some of her men were landed on the island, where they were later taken off by a United States Coast and Geodetic Survey ship. The rest were rescued from the battered Cardinal on 7 June by the oiler Cuyama, who also took off salvageable material and stores. The remaining hulk sank soon thereafter.
