The final military engagement in Newfoundland occurred in the fall of 1762 and was the final action in the Anglo-French war of 1756-63 known as
Battle of Signal Hill. British victories at Louisbourg (1758),
Quebec City (1759) and
Montreal (1760) virtually eliminated the French presence in North America and led to the opening of peace negotiations under conditions of great disadvantage to France. Desperate to recover a bargaining counter, the French government dispatched a naval force with 800 troops to attack Newfoundland. Following earlier French-Canadian strategy,
Comte d'Haussonville, the French commander, marched overland on St. John's from a landing in the undefended harbour at
Bay Bulls. The British garrison in Fort William, few in numbers and without well-prepared defences, made no resistance and surrendered on June 17. The British Command in
New York quickly organized a counterstroke. By September, 1500 regular and
New England troops had been convoyed to the
Avalon Peninsula and, on September 13, their commander, Lt. Col.
William Amherst, made a landing at
Torbay eight miles north of St. John's. Marching overland, Amherst drove the French from their outer defences at
Quidi Vidi Pass and on the 15th captured the high ground of
Signal Hill in a surprise dawn assault. With the French force now confined to Fort William, Amherst occupied the following two days bringing up heavy guns to reduce the fortifications: meanwhile the French warships which had convoyed d'Haussonville's force and which remained in St. John's harbour, escaped under cover of a thick fog. Amherst's batteries - one on the lower slope of Signal Hill and another north of the Fort on high ground along King's Bridge Road - were ready by the 17th and began an intensive bombardment of Fort William that day. Surrounded and unsupported, d'Haussonville's force capitulated on September 18. == Demolition ==
