French forces besieging Quebec retreat after the Royal Navy arrives to relieve the British garrison.

The siege of Quebec, also known as the second siege of Quebec, was a 1760 French attempt to retake Quebec City, in New France, which had been captured by Britain the previous year. The siege lasted from 29 April to 15 May, when British ships arrived to relieve the city and compelled the French commander, François Gaston de Lévis, to break off the siege and to retreat. The British launched the Montreal campaign a few months later, which resulted in the city's capture. French resistance ceased, and the British conquest of New France was complete, as was confirmed in 1763 by the Treaty of Paris.

The Royal Navy (RN) is the naval warfare force of the United Kingdom. It is a component of His Majesty's Naval Service, and its officers hold their commissions from the King. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the English Navy of the early 16th century; the oldest of the UK's armed services, it is consequently known as the Senior Service.
