British soldiers and Provincial militiamen repulse the American assault at Sault-au-Matelot, Canada, December 1775

Three weeks after the siege of Boston began, the Green Mountain Boys, a group of militia volunteers led by Ethan Allen and Benedict Arnold, captured Fort Ticonderoga, a strategically important point on Lake Champlain between New York and the Province of Quebec. After that action they also raided Fort St. John's, not far from Montreal, which alarmed the population and the authorities there. In response, Quebec's governor Guy Carleton began fortifying St. John's, and opened negotiations with the Iroquois and other Native American tribes for their support. These actions, combined with lobbying by both Allen and Arnold and the fear of a British attack from the north, persuaded the Congress, on June 27, 1775, to authorize an invasion of Quebec, with the goal of driving the British military from that province. (Quebec was then frequently referred to as Canada, as most of its territory included the former French Province of Canada.)^[49]
Two Quebec-bound expeditions were undertaken. On September 28, 1775, Brigadier General Richard Montgomery marched north from Fort Ticonderoga with about 1,700 militiamen, besieging and capturing Fort St. Jean on November 2 and then Montreal on November 13. General Carleton escaped to Quebec City and began preparing that city for an attack. The second expedition, led by Colonel Arnold, went through the wilderness of what is now northern Maine. Logistics were difficult, with 300 men turning back, and another 200 perishing due to the harsh conditions. By the time Arnold reached Quebec City in early November, he had but 600 of his original 1,100 men. Montgomery's force joined Arnold's, and they attacked Quebec City on December 31, but were defeated by Carleton in a battle that ended with Montgomery dead, Arnold wounded, and over 400 Americans taken prisoner.^[50] The remaining Americans held on outside Quebec City until the spring of 1776, suffering from poor camp conditions and smallpox, and then withdrew when a squadron of British ships under Captain Charles Douglas arrived to relieve the siege.^[51]
Another attempt was made by the Americans to push back towards Quebec, but they failed at Trois-Rivières on June 8, 1776. Carleton then launched his own invasion and defeated Arnold at the Battle of Valcour Island in October. Arnold fell back to Fort Ticonderoga, where the invasion had begun. While the invasion ended as a disaster for the Americans, Arnold's efforts in 1776 delayed any full-scale British counteroffensive until the Saratoga campaign of 1777.
The invasion cost the Americans their base of support in British public opinion, "So that the violent measures towards America are freely adopted and countenanced by a majority of individuals of all ranks, professions, or occupations, in this country."^[52] It gained them at best limited support in the population of Quebec, which, while somewhat supportive early in the invasion, became less so later during the occupation, when American policies against suspected Loyalists became harsher, and the army's hard currency ran out. Two small regiments of Canadiens were recruited during the operation, and they were with the army on its retreat back to Ticonderoga.^[53] Even after their retreat, the Patriots continued to view Quebec as a part of their cause and made specific provisions for it to join the U.S. under the 1777 Articles of Confederation.

Expelling the royal officials

At the onset of war, the British had a significant force only in Boston, though this force would evacuate by the signing of the Declaration of Independence in 1776. Patriots in all 13 colonies were quick to establish new revolutionary governments based around various committees and conventions that they had created in 1774 and early 1775. Royal governors and officials found themselves powerless to stop the rebellion and in many places were forced to flee. In many places the Patriots were energetic and were backed by angry mobs while the Loyalists were too intimidated or poorly organized to be effective without the British army. The term "lynching" originated when Virginia Patriots held informal courts and arrested Loyalists (the term did not suggest execution)
