On this day 250 years ago in the Delaware River, the 13 row galleys of the Pennsylvania Navy each carrying a single cannon continued their engagement with the British warships HMS Roebuck with 48 guns and Liverpool with 28 guns, plus their tenders and prizes. Although the Patriots were significantly outgunned by the British ships, they were able to push the British fleet downstream below New Castle, Delaware. The Americans reported no casualties but the British lost one man killed and ten or so men wounded.
