Lacking sufficient logistical and artillery support, and hampered further by a blinding snowstorm on 21 March, French forces were unable to take the fort and the siege was called off.

Although the French failed to take the fort itself, their forces did destroy three hundred bateaux and several lightly armed vessels beached on the shore, a saw-mill and numerous outbuildings.

Although starved for information, Monro could do little to respond to the Indian raids or gain intelligence on French movements until sufficient reinforcements arrived.

In June reinforcements finally did arrive when Provincial and militia units from New York, New Jersey and New Hampshire were sent up from Fort Edward by General Daniel Webb.

His plan was to gather all available boats, pack them with approximately 350 men and send them north up the lake into an area controlled by an enemy he knew little about.

It was decided to land Colonel Parker's flotilla of men on Sabbath Day Point situated approximately 20 miles (32 km) north of Fort William Henry on the west side of Lake George.

On 21 July a force of approximately 450 French and Indian men under the command of Ensign de Corbiere departed Fort Carillon to intercept.

[4] In the early morning hours of 23 July Parker's main force approached Sabbath Day Point unaware that the French had intercepted his three lead boats and learned his plan.

[4] Colonel Parker, lucky to escape the onslaught, led what was left of his men through the brush and thick forest back to Fort William Henry.
