He broke open the hatch on the catamaran, retrieved the string and stepped into his gig as he pulled it. Twenty-five seconds later the vessel exploded but the explosion did no damage except remove the praam's bowsprit. When Jackson returned to the Downs he was invited to dine with Prime Minister William Pitt, Lord Harrowby, and Lord Melville. Melville promised to promote Jackson, but Melville left office before he could make good on his promise. (Jackson received promotion to post-captain in 1807, after he had left "Autumn".) Commander Thomas Searle assumed command "Autumn" in October 1804. "Autumn" shared with the gun-brigs , , and , in the salvage money for "George" which they retook in February 1805. It was believed that "George" had been sailing from Bristol to London when a French privateer had captured her and taken her into Boulogne, where her cargo was landed. "Autumn" and the brigs recaptured "George" as she was on her way to Calais and they sent her into Dover. In October 1805, "Autumn" was at Portsmouth where she underwent fitting as a receiving ship. In October 1809 Commander Corbet James d'Auvergne recommissioned her. Between December 1810 and May 1811, "Autumn" was refitted at Portsmouth as a bomb vessel. On 15 February 1811 she was renamed "Strombolo". Commander Samuel Grove recommissioned her in March. On 11 December he sailed her for the Mediterranean. During 1812 she came under the command of Commander Thomas Hichens, Commander John Stoddard on 3 July, then Grove again, and Commander John Smith in August. By June 1813 Commander John Stoddart had again assumed command of "Strombolo". Between 3 and 7 June 1813, "Strombolo", Captain Stoddard, participated in an Army-Navy operation that captured Fort St Philippe in the Coll de Balanguer that controlled the pass on the road between Tortosa to Tarragona. The naval force consisted of , , "Brune", "Strombolo", and , and eight gunboats. Lieutenant James, RMA, landed two 8" mortars from "Strombolo" and commenced to fire on the fort while guns from squadron were being landed to establish a breaching battery. After the mortar shells blew up the fort's magazine, the garrison surrendered though the battery had not yet commenced fire.
