The second USS Boston was a 24-gun frigate, launched 3 June 1776 by Stephen and Ralph Cross, Newburyport, Massachusetts, and completed the following year. In American service she captured a number of British vessels. The British captured Boston at the fall of Charleston, South Carolina, renamed her HMS Charlestown (or Charles Town), and took her into service. She was engaged in one major fight with two French frigates, which she survived and which saved the convoy she was protecting. The British sold Charlestown in 1783, immediately after the end of the war.
