The Battle of Fort Oswego was one in a series of early French victories in the North American theatre of the Seven Years' War won in spite of New France's military vulnerability. During the week of August 10, 1756, a force of regulars and Canadian militia under General Montcalm captured and occupied the British fortifications at Fort Oswego, located at the site of present-day Oswego, New York.

In addition to 1,700 prisoners, Montcalm's force seized the fort's 121 cannons. The fall of Fort Oswego effectively interrupted the British presence on Lake Ontario and removed it as a threat to the nearby French-controlled Fort Frontenac. The battle was notable for demonstrating that traditional European siege tactics were viable in North America when applied properly in the right circumstances and terrain.
