She then conveyed Sir Neil Campbell to Sierra Leone in August 1826, being present in the aftermath of the Katamanso War at Cape Coast Castle in September.

[4][5] The class was based on the lines of the captured French 38-gun frigate Hébé, a design by Jacques-Noël Sané vaunted as an all-rounder.

The naval historian Robert Gardiner argues that the key characteristic of the design, leading to its adoption by the Royal Navy, was its "unspectacular excellence".

[1] This meant she was moored in harbour with her guns, stores, and upper masts removed, manned by a small group of warrant officers.

[14] Upon her completion plans had initially been made to commission Lively; in May Captain Frederick Aylmer had taken the frigate under control in preparation for this, but the orders were cancelled.

With troops under his command Miguel started arresting his enemies, one of whom was Manuel Inácio Martins Pamplona Corte Real, 1st Count of Subserra.

Looking to assist Subserra in escaping Miguel, the French and British ambassadors, Jean-Guillaume, baron Hyde de Neuville and Sir Edward Thornton, organised for him to go on board Lively.

[16] Fearing that John was also at risk of arrest by Miguel, de Neuville tried to organise for the French 80-gun ship of the line Santi Pietri to take him from Lisbon.

Santi Pietri never arrived from Cadiz and Thornton instead convinced John to board the 98-gun ship of the line HMS Windsor Castle, which was already present with Lively.

[25] Lively afterwards served off the coast of North America, where Spanish attempts to reconquer Mexico were underway at San Juan de Ulúa Castle in Veracruz.

Mexican forces captured the castle from the Spanish in November, and Lively returned to Britain with despatches announcing the loss.

Departing from Spithead on 20 July, Campbell arrived at Sierra Leone on 26 August and then had Lively take him to Cape Coast Castle.

Reaching there on 22 September, Campbell learned that the Ashanti Empire had attacked Cape Coast and been defeated in the Katamanso War on 7 August.
