At noon on 9 February, while cruising independently, Truxtun's men sighted a frigate off the coast of
Nevis. Upon approach it was evident that the vessel was flying American colors, and
Constellation attempted to move closer to investigate. Unknown to Truxtun, the frigate was the French ''L'Insurgente
under Michel-Pierre Barreaut. Nearing the still-unidentified L'Insurgente
, Truxtun attempted to signal her to discern her nationality by displaying first British signals and then American signals. Not knowing the correct reply, L'Insurgente
replaced the American colors with French and fired a gun. As a result of the storm, L'Insurgente
lost her main topmast and was severely damaged, while Constellation'' managed to avoid significant damage and was able to close in on Barreaut. Though Truxtun's ship initially held an advantageous position in the wind known as the
weather gauge, she was over-armed, and as a result her
leeward side
heeled so much that the gunports on that side of the vessel could not be opened. Truxtun decided to cede the weather gauge to the French by sailing around ''L'Insurgente
s leeward side and bringing Constellation'' near the French frigate's
port side. In such a position
Constellation was disadvantaged by the wind, but was able to avoid some of the heeling effect on her guns. With
Constellation approaching his frigate fast, Barreaut tried to communicate with the Americans in order to avoid a fight. The American frigate ignored the French attempt at hailing her and closed to within fifty yards of ''L'Insurgente'' before opening up on her with a
broadside. The
double-shotted American salvo severely damaged the French frigate's
quarterdeck. Barreaut's vessel replied with her own broadsides that damaged ''Constellation's
fore topmast. Midshipman David Porter, stationed in the rigging of Constellations'' damaged mast, managed to relieve pressure from it and prevented its collapse.
Constellation crossed ''L'Insurgente
s bow and raked her with a broadside. Truxtun then maneuvered Constellation
to L'Insurgente
s starboard side and fired further broadsides into the French frigate, but received damage to her rigging in return. Constellation
slipped ahead of L'Insurgente
, again crossing her bow and raking her. Once more Constellation
slipped next to L'Insurgente''s leeward side and fired into her, disabling the French vessel's 18-pounder guns.
Constellation crossed the frigate's bow a third time, but the French ship had by then sustained massive damage. Attempts by Barreaut's crew to repair ''L'Insurgente''s rigging were fruitless and the French captain
struck his colors to surrender the vessel. The engagement had lasted 74 minutes. ==Aftermath==
