The Battle of Fort Niagara was a siege late in the French and Indian War, the North American theatre of the Seven Years' War. The British siege of Fort Niagara in July 1759 was part of a campaign to remove French control of the Great Lakes and Ohio Valley regions, making possible a western invasion of the French province of Canada in conjunction with General James Wolfe's invasion to the east.
