Caledonia, Valiant, , and the hired armed cutter Nimrod. The next day, Piercer captured the French sloop Saint Pierre. Piercer was part of a squadron under Captain James Newman-Newman in when the squadron captured the American vessel Beauty on 1 February 1811. Sibrell died in June and Lieutenant Joshua Kneeshaw assumed command. On 14 August 1811 Piercer captured the chasse marees Marengo and Phillippe, off the Sables d'Olonne. Two weeks later, Piercer was in company with when they captured the Catharina Augusta. In December Piercer witnessed an unfortunate occurrence for the Royal Navy. On the 27th, and sent 120 men in six boats to attack a French convoy sailing along the shore in the Basque Roads. As the boats approached their quarry just south of the Chatillon Reef, the wind shifted, which permitted the convoy's escorts, three gun-brigs, an armed lugger and several pinnaces, to sally out and get between the British boats and their parent vessels.

The French reported capturing 113 men, perhaps including five British sailors who were killed, two who died soon after, and several who were dangerously wounded. When he saw the French attacking, Captain Lord William Stuart of Conquestador signaled Piercer to protect the British boats and sent her a boat with eighteen seamen and marines as reinforcements, but she was unable (or unwilling) to do so.
