Broadsides from Foudroyant caused significant damage and after engaging about three-quarters of an hour, Foudroyant boarded Pégase, and compelled her commander Chevalier de Sillans to surrender.
In the morning of the 21st some of the squadron again joined company and with the disabled state of Pégase and the continuation of a strong gale with heavy seas induced Captain Jervis to the signal for immediate assistance.
