On the 19th of July 1805, the French frigate Topaze (40), and corvettes Départment des Landes (22), Torche (18), and Faune (16) captured the HMS Blanche off the coast of Puerto Rico. The Blanche was subsequently burned.

On the 19th of July 1806, the newly named HMS Blanche, formally the Spanish ship Amfitrite, captured the Guerrière. Blanche, having 46 guns, spotted the French ship of 50 guns, and closed on her without the French ship taking action. At 0015, Blanche fired two broadsides at Guerrière, followed by an intense engagement. While the French frigate focused on Blanche’s sails and rigging, hoping to cripple the British frigate sufficiently to escape, Blanche severely pounded the Guerrière, which eventually struck colors at 0130.
