The Invasion of Canada in 1775 was the first major military initiative by the United States during the American Revolutionary War. Two separate expeditions were launched, which joined forces and were defeated at the Battle of Quebec in December 1775. The British then launched a counter-offensive in 1776, driving the Americans back to Fort Ticonderoga. The end of the campaign set the stage for the Saratoga campaign of 1777.
Congress had previously invited French-Canadians to join the American Revolution as the fourteenth colony, but this failed to happen. Therefore, a plan was devised to drive the British Empire from the primarily francophone colony of Quebec (comprising present-day Quebec and Ontario). Two expeditions were undertaken.
Congress authorized General Philip Schuyler, commander of the Northern Department, to mount an invasion to drive British forces from Canada. He sent General Richard Montgomery north with an invasion force. General George Washington also sent Benedict Arnold towards Quebec with a supporting force.
Arnold eventually selected a force of 750 men. Washington was happy to add Daniel Morgan's company and some other riflemen. The frontiersmen, from the Virginia and Pennsylvania wilderness, were better suited to wilderness combat than to a siege.
The plan called for the men to cover the 180 miles from the Kennebec River to Quebec in 20 days. They expected to find relatively light defenses since the British commander, Sir Guy Carleton, would be busy handling Schuyler's forces at Montreal. Arnold sent ahead to Fort Western (present day Maine) to have supplies and bateaux readied for his force. The expedition moved by sea, and spent five days at Fort Western organizing supplies and boats.
The men expected to go up the Kennebec River and then descend the Chaudiere to Quebec. After staying for three days at Colburn's Shipyard in Gardinerston, where Reuben Colburn built the bateaux at Washington's request in just 15 days, they set out from Fort Western on September 25. Their troubles began almost immediately.
The bateaux were built from green, split pine planks, due to a lack of dried lumber at that time of year, and were basically flat bottom rafts that could not be rowed, but poled against the stream. Colburn travelled with the army, repairing the bateaux as they went, but in hauling them upstream and lowering them down the Chaudiere, many supplies and some men were lost. Rain and violent storms ruined more. Lieutenant Colonel Roger Enos turned back with his division, taking 300 men and more of the supplies with him.
The maps the expedition started with were faulty, as the British frequently allowed publication of incorrect maps to deceive future enemies. The journey was 350 miles, not 180. After the expedition ran out of supplies, and began to eat anything, including their dogs, their shoes, cartridge boxes, leather, moss, and tree bark. On November 6, the expedition reached the south shore of the St. Lawrence River; Arnold had 600 of his original 1,100 men.
Arnold thought they could still take the city. The defenders had only about 100 regulars under Lt. Colonel Allen Maclean, supported by several hundred poorly organized militia. If the Americans could scatter the militia with accurate fire, they could overwhelm the outnumbered regulars. When they finally reached the Plains of Abraham on November 14, Arnold sent a negotiator with a white flag to demand their surrender, to no avail. The Americans, with no cannons, faced a fortress city. When the frigate Lizard moved into the river to cut off their rear, they were forced to withdraw to Pointe aux Trembles.
Finally, on December 2, Montgomery came down river from Montreal with 300 troops and brought captured British supplies and winter clothing. The two forces joined and the stage was set for an attack on the city.
Montgomery joined Arnold, and they attacked Quebec City on December 31, but were soundly defeated by Carleton. Montgomery was killed, Arnold was wounded, and many men were taken prisoner, including Daniel Morgan and Ethan Allen. When General John Thomas arrived to take command, he found the army severely weakened by the march north, smallpox, and the harsh Canadian winter. He immediately began a withdrawal.
Carleton then launched his own invasion, and defeated Arnold in the Battle of Valcour Island in October. Arnold fell back to Fort Ticonderoga, where the invasion of Canada had begun. The invasion of Canada ended as a disaster for the Americans, but Arnold's improvised navy on Lake Champlain had the effect of delaying a full-scale British counter thrust until the Saratoga campaign of 1777. Carleton was heavily criticized in London for not pursuing the American retreat from Canada more aggressively, and so command of the 1777 offensive was given to General Burgoyne instead.
