Valeureuse took part in the Atlantic campaign of 1806 in Willaumez's squadron. The French squadron left Brest on 14 December 1805. On 9 March 1806 the squadron was at -15.3667°N -38°W, some 150 leagues west of Saint Helena.[1]
On the cruise Valeureuse visited São Salvador, Guyane, and Fort-de-France.
On 14 August 1806 Valeureuse captured and sank the merchantman Hebe, Teuton, master, which had been sailing from Trinidad to Bermuda.[2]
In August 1806, a storm caused Valeureuse to separate from the fleet. She took refuge on 31 August in Delaware Bay, where she arrived dismasted.[3] Valeureuse was in such a bad state that she had to be sold.
On 24 October Lloyd's List reported that Valeureuse had gone into Philadelphia.[2] She was condemned at Philadelphia,[4] and was sold at Marcus Hook, Pennsylvania.
Her officers and crew, and stores were put aboard the American ship George Washington.[4] On 15 January 1807 HMS Blanche intercepted George Washington off Bordeaux. The British found that she was carrying Captain Kargarian (Kergariou), the former commander of Valeureuse, and 306 of his officers and men, but no stores from Valeureuse. The British took the Frenchmen aboard Blanche as prisoners and then sent George Washington to England. George Washington arrived at Portsmouth on 2 February.[4]
