The 1759 Battle of Ticonderoga is a minor confrontation at Fort Carillon (later renamed Fort Ticonderoga) on July 26 and 27, 1759, during the French and Indian War.

A British military force of more than eleven thousand men under the command of General Sir Jeffery Amherst moves artillery to high ground overlooking the fort, which is defended by a garrison of four hundred Frenchmen under the command of Brigadier General François-Charles de Bourlamaque.

Rather than defend the fort, de Bourlamaque, operating under instructions from General Louis-Joseph de Montcalm and New France's governor, the Marquis de Vaudreuil, withdraws his forces, and attempts to blow up the fort.

The fort's powder magazine is destroyed, but its walls are not severely damaged.

he British then occupy the fort, which is afterwards known by the name Fort Ticonderoga.

They embark  on a series of improvements to the area and begin construction of a fleet to conduct military operations on Lake Champlain.

The French tactics are sufficient to prevent Amherst's army from joining James Wolfe at the Battle of the Plains of Abraham.

However, they also tie up three thousand of their own troops that are not able to assist in Quebec's defense.

The capture of the fort, which had previously repulsed a large British army a year earlier, contributes to the Annus Mirabilis of 1759.
