The Concorde Class frigates were fifth-rate, 32-guns, fast and maneuverable ships. They were armed with twentysix 12-pounder long guns on the main battery and lighter pieces of artillery – four 6-pounder guns on the forecastle and two on the poop deck – and were designed for a crew of 280. The Sirena 1793 was a frigate of the Spanish Armada that had previously served in the French Navy under the name Elene. Captured in May 1793 by frigates Santa Casilda and Perla, it returned to active service with the fleet based in Havana, doing mostly escorting service. In 1807, it was wrecked on the coast of Campeche (Mexico).
