The keel of HMS Undaunted was laid down in April 1806 under the supervision of naval constructor Edward Sison. This vessel belonged to a class of sixteen ships based on a design dating from 1799 by William Rule, the Surveyor of the Navy.
Thomas Ussher remained under command of HMS Undaunted off Marseille on the evening of the 24th of April 1814 when Napoleon and his followers boarded the ship. The vessel arrived at Elba on the 30th of April and Napoleon disembarked on the 3rd of May 1814 to formally take possession of the island before Ussher relinquished command on the 29th of June 1814.
On the 1st of February 1834 the Undaunted ran aground off Selsey Bill in West Sussex. She was subsequently put out of commission later that year and laid up at Portsmouth for many years until she was used as a target during testing of molten-iron filled shells on the 24th of November 1859.
The total cost for building this fifth-rate 38-gun sailing frigate reached £36,967. These figures represented a significant investment during the height of the Napoleonic Wars.
HMS Undaunted sank using conventional shot after an iron shell test caused catastrophic damage on the 24th of November 1859. The ship was finally broken up in 1860 following her destruction which marked the conclusion of a long service history spanning over fifty years from construction to sinking.
