Oswego Fortification System

Many historic references to Fort Oswego actually refer to other forts. The terrain at the site explains this. The original fort was built around the trading post on the lower ground on the south east side of the river. This was convient to canoe and bateaux traffic. A Stone Blockhouse was added in 1727, and was called Fort Burnet. A triangular stone wall, ten feet high and three feet wide was added in 1741, and the entire enclusure was called Fort Pepperrell. Besides these expansions, Fort Ontario as built on the high ground on the north side of the river, and Fort George was added to the bluff located a half mile to the southwest.

The French and Indian War

During the French and Indian War, the French commander, General Montcalm, arrived in August with 3,000 men. His force included 3 regiments of regulars, several companies of Canadian militia, and numerous Indians. He first captured Fort Ontario, then began the assault on Fort Oswego. Oswego was the stronger fortification, but it was now down hill from 120 cannons in the abandoned Fort Ontario. Montcalm swept the fort with cannon fire, killing the British commander, Colonel Mercer, in the bombardment. British forces were forced to surrender on August 15, 1756.

Montcalm gave much of the British supplies to his Indian allies, and destroyed the fort. He returned to Quebec in triumph with 1,700 prisoners. His actions made a very strong impression on the Indian allies of the British, and caused te Onieda and the Senecca tribes to switch to the french side.
