Though, I suspect there are different versions, below is my understanding of the events.

In 1689 France and England was at war. English colonists in New York heard the news first and convinced their Iroquois allies to attack the French. Most French colonies were unfortified. 1,500 Iroquois attacked Lachine near Montreal, which became known as the Lachine massacre. Of the 375 inhabitants, 24 were killed and 76 others were taken prisoner. Fifty-six of the 77 buildings were razed to the ground.

following the Lachine Massacre, France ordered a retaliatory attack on the Albany in the British colony of New York. This war, the first in the British and French colonies, would come to be known as King William's War.

In February 1690 France, began an invasion. One hundred and sixteen militiamen and 96 Indian allies reached the fort at Schenectady and massacred 60 settlers and burned most of the British colonial settlement.

This led to more back and forth military raids and conflicts, which resulted in (what is now Canada) becoming a British colony.
