Later she was rebuilt for a second time by John Naish of Portsmouth but using Chatham Dockyard from 1714, relaunching on 3 September 1719. She was laid up after her re-launch and saw no service at all until she was reduced to an 84-gun Second rate ship in 1756.[2] One year later, she was part of an unsuccessful expedition against Rochefort led by AdmiralSir Edward Hawke. Her squadron, under Vice-Admiral Charles Knowles, attacked the Île-d'Aix and forced her garrison to surrender.[6] In 1758 she participated in Boscawen's and Wolfe'sattack on the French Fortress of Louisbourg (Nova Scotia) and an indecisive skirmish with a French squadron.[7] The following year Royal William returned to Canada under the command of Captain Hugh Pigot to join the attack on Quebec. After the Battle of the Plains of Abraham and the capture of Quebec she sailed back to England with the body of General Wolfe.[8] In 1760 Royal William was Boscawen's flagship when he took command of the fleet in Quiberon Bay. However, after a severe gale he was forced to return and shift his flag to HMS Namur.[9] During the expedition against Belle Île of 1761 she was detached with several other ships to cruise off Brest and prevent a French counter-attack from there.[10]
The Seven Years' War seems to be the last time that Royal William played an active role. She was broken up in 1813.[2]
