The Battle of Fort Bull is a French attack on the British-held Fort Bull on March 27, 1756, early in the French and Indian War.

The fort had been built to defend a portion of the waterway connecting Albany, New York to Lake Ontario via the Mohawk River.

Lt. Gaspard-Joseph Chaussegros de Léry leads his command consisting of forces from the Troupes de la Marine, Canadien militia, and Indian allies on an attack against Fort Bull on March 27, 1756.

Shielded by trees, they sneak up to within one hundred yards (ninety-one meters) of the fort.

Léry orders a charge at the fort with bayonets.

The attackers stick their muskets into the narrow openings in the fort and shoot the defenders.

Léry repeatedly asks for their surrender.

Finally, the gate is breached and the French and Indians swarm  in, killing everyone they see.

The French soldiers loot what they can and set the powder magazines on fire.

The fort is burned to the ground.
