Throughout the siege of Louisbourg, the fleet actively supported the British Army and the fortress finally surrendered on 26 July.

In February 1759, the frigate sailed from Spithead as part of the fleet destined for the expedition against Québec under command of Vice-Admiral Charles Saunders.

On 23 June, Saunders' fleet made a junction with a squadron led by Commodore Philip Durell at Île-aux-Coudres.

On 26 June, the whole British fleet of Vice-Admiral Saunders was anchored safely off the southern shore of Île d'Orléans, a few kilometres below Québec without losing a single ship.

At the end of October 1759, Vice-Admiral Saunders fired his farewell salute and departed the St. Lawrence River with his fleet to return to Great Britain.
