War of the American Revolution, 1775-1781
In 1775, an American army under the command of General Robert Montgomery captured Montréal on behalf of the thirteen American colonies. Montgomery joined with General Benedict Arnold to lay siege to Québec city, however the attack ended in failure and by June of 1776 the Americans were driven from Montréal. The colonies issued their Declaration of Independence in 1776 and finally, after years of battle, England acknowledged the independence of the United States by the Treaty of Paris in 1783.
