In July 1808, the master of an American brig claimed the protection of a convoy from Jamaica, which was being escorted by the 64-gun HMS "Veteran". The American traveled with the convoy for part of its journey, but twenty four hours after leaving its protection, he betrayed the strength and course of the convoy to the French. The French privateer cutter "Peraty", under the command of M. Maurison, took up position in the convoy's path, hoping to capture some of the ships. "Guerrière" surprised and captured the privateer after a chase lasting 24 hours. The privateer was found to be the former HMS "Barbara", which the French privateer "General Ernouf" had captured on 17 September 1807. The prize crew had sailed "Barbara" to Charlestown, where she had been refitted. As "Peraty", she had sailed again on 10 September, having been furnished with supplies and provisions for three months of raiding. "Peraty" was armed with twelve 18-pounder carronades and had a crew of 80 men.
