The Battle of the Delaware Capes or the 3rd Battle of Delaware Bay was a naval engagement that was fought off the Delaware River towards the end of the American Revolutionary War. The battle took place on the 20th and the 21st December 1782, some three weeks after the signing of the preliminary articles of peace between Great Britain and the former American colonies, and was an engagement between three British Royal navy frigates HMS Diomede, Quebec and Astraea on the one side, and the South Carolina Navy's 40-gun frigate South Carolina, the brigs Hope and Constance, and the schooner Seagrove on the other. The British were victorious with only Seagrove escaping capture.
