That month, Alonzo was off Bognor when a three-day long gale resulted in her losing her masts and rudder, springing a dangerous leak, and coming close to being lost.

Midshipman James Hervey Price managed to get ashore with dispatches on the third day and convey them to a signal station, which transmitted news of Alonzo's plight to Portsmouth.

[6] On 2 April Alonzo sailed from Deal with a British squadron that was to escort some "stone ship' to Boulogne where they were to be scuttled to block the harbour.

[8] In July 1804 Commander James Watson replaced Impey, with Alonzo serving on the Downs station.

[2] In 1809 the ship James, Gregg, master, ran aground in the Great Belt whilst on a voyage from Liverpool, Lancashire to Stockholm, Sweden.

The gunboats (Husaren, Løberen, and Flink) sought refuge in Grenå, on eastern Jutland, where a company of soldiers and their field guns could provide cover.

However, the British mounted a cutting out expedition of some 200 men in ten ships’ boats after midnight on 7 July, capturing the three gunboats.

[2] Alonzo, Gorgon, Victory, and the gun-brig Martial shared in the proceeds of the capture on 24 October 1810 of the brig Hoppet.

[17] Between September and March 1815 Alonzo was at Woolwich undergoing fitting for service as a hospital ship for convicts.
