Cambrian captured the French privateer schooner Mathilde on 3 July 1805, after a chase of 22 hours.

[b] She surrendered in shoal water and if not for the efforts of Lieutenant Pigot in one of Cambrian's boats, Mathilde's entire crew might have been lost.

[3] Pigot engaged the vessels for an hour, and after Matilda had grounded, took his crew in her boats and captured Golden Grove.

[3] Pigot was unable to extricate himself and his prizes from the river until 21 July, but during the entire period he remained in command except when he was getting his wounds dressed.

For his efforts Pigot received a promotion to commander, and the Lloyd's Patriotic Fund awarded him a medal and a plate worth £50.
