The Battle of Restigouche was a naval battle fought between the British Royal Navy and the French Navy on the Restigouche River in 1760 amid the French and Indian War.
Even after Quebec City's fall to the British in September 1759, large numbers of French forces remained in New France, although the prospect of reinforcements was made difficult because of the French Navy's destruction at the Battle of Quiberon Bay in November 1759. In April 1760, a French frigate escorted five merchant ships from Bordeaux to Canada, carrying Francois-Gabriel d'Angeac's 400 reinforcement troops. By 15 May 1760, three of the French ships made it to the Gulf of St. Lawrence, two others having been seized and one run aground in the Azores. The surviving French ships anchored in the estuary of the Restigouche River and enlisted the help of Mikmaq villagers and Acadian refugees. A Royal Navy flotilla led by Captain John Byron sailed from Louisbourg to intercept the French, attacking on 28 June.
1,500 Acadian and Mikmaq militiamen on schooners and small boats fired on the British flotilla, which maneuvered beyond a chain of sunken ships and fired on a French battery. Skirmishing continued from 28 June to 3 July, when the British overcame Pointe-a-la-Batterie and burned its village. The militias created a new blockade and two new batteries, but Byron overcame these new batteries after three tries and heavy damage. Ultimately, all of the French ships and most of the Acadian boats were sunk, but the British were unable to make a landing due to fierce resistance. The Acadian settlers were forced to relocate, while the Mikmaq made peace with Britain by the end of the following year. The loss of the supply convoy sealed the fate of Montreal, which fell to the British on 8 September.
