US frigate 'Alliance' captures HMSs 'Atalanta' & 'Trepassy' off Nova Scotia

At first dawn, the unknown ships hoisted British colors and prepared for battle. Although all three ships were almost completely becalmed, the American drifted within hailing distance of the largest British vessel about an hour before noon; Barry learned that it was the sloop of war HMS Atalanta. Her smaller consort proved to be Trepassey, also a sloop of war. The American captain then identified his own vessel and invited Atalanta's commanding officer to surrender. A few moments later, Barry opened the inevitable battle with a broadside. The sloops immediately pulled out of field of fire of the frigate's broadsides and took positions aft of their foe where their guns could pound her with near impunity In the motionless air, Alliance – too large to be propelled by sweeps – was powerless to maneuver.
A grapeshot hit Barry's left shoulder, seriously wounding him, but he continued to direct the fighting until loss of blood almost robbed him of consciousness. Lieutenant Hoystead Hacker, the frigate's executive officer, took command as Barry was carried to the cockpit for treatment. Hacker fought the ship with valor and determination until her inability to maneuver out of her relatively defenseless position prompted him to seek Barry's permission to surrender. Indignantly, Barry refused to allow this and asked to be brought back on deck to resume command.
Inspired by Barry's zeal, Hacker returned to the fray. Then a wind sprang up and restored Alliance's steerage way, enabling her to bring her battery back into action. Two devastating broadsides knocked Trepassey out of the fight. Another broadside forced Atalanta to strike, ending the bloody affair. The next day, while carpenters labored to repair all three ships, Barry transferred all of his prisoners to Trepassey which – as a cartel ship – would carry them to St. John's, Newfoundland, to be exchanged for American prisoners. HMS Charlestown recaptured Atalanta in June and sent her into Halifax.
