Richard Montgomery in the context of "Fort Detroit"

The invasion of Quebec (June 1775 – October 1776, French: Invasion du Québec) was the first major military initiative by the newly formed Continental Army during the American Revolutionary War. The objective of the campaign was to seize the Province of Quebec (part of modern-day Canada) from Great Britain, and persuade French-speaking Canadiens to join the revolution on the side of the Thirteen Colonies. One expedition left Fort Ticonderoga under Richard Montgomery, besieged and captured Fort Saint-Jean, and very nearly captured British General Guy Carleton when taking Montreal. The other expedition, under Benedict Arnold, left Cambridge, Massachusetts, and traveled with great difficulty through the wilderness of Maine to Quebec City. The two forces joined there, but were defeated at the Battle of Quebec in December 1775.

Montgomery's expedition set out from Fort Ticonderoga in late August, and in mid-September began besieging Fort St. Johns, the main defensive point south of Montreal. After the fort was captured in November, Carleton abandoned Montreal, fleeing to Quebec City. Montgomery took control of Montreal before heading for Quebec, his army much-reduced by expiring enlistments. There he joined Arnold, who had left Cambridge in early September on an arduous trek through the wilderness that left his surviving troops starving and lacking supplies and equipment.

Montgomery is the capital city of the U.S. state of Alabama and the seat of Montgomery County. It was named for Continental Army Major-General Richard Montgomery and stands beside the Alabama River on the Gulf Coastal Plain.

The population was 200,603 at the 2020 census. It is the third-most populous city in the state, after Huntsville and Birmingham, and the 133rd-most populous in the United States. The Montgomery metropolitan area's population in 2022 was 385,460; it is the fourth-largest in the state and 142nd among U.S. metropolitan areas.

The Battle of Quebec (French: Bataille de Québec) was fought on December 31, 1775, between American Continental Army forces and the British defenders of Quebec City as part of the invasion of Quebec of the American Revolutionary War. The battle was the first major defeat of the war for the Americans, and it came with heavy losses. General Richard Montgomery was killed, Benedict Arnold was wounded, and Daniel Morgan and more than 400 men were taken prisoner. The city's garrison, a motley assortment of regular troops and militia led by Quebec's provincial governor, General Guy Carleton, suffered a small number of casualties.

Montgomery's army had captured Montreal on November 13, and early in December they became one force that was led by Arnold, whose men had made an arduous trek through the wilderness of northern New England. Governor Carleton had escaped from Montreal to Quebec, the Americans' next objective, and last-minute reinforcements arrived to bolster the city's limited defenses before the attacking force's arrival. Concerned that expiring enlistments would reduce his force, Montgomery made the end-of-year attack in a blinding snowstorm to conceal his army's movements. The plan was for separate forces led by Montgomery and Arnold to converge in the lower city before scaling the walls protecting the upper city. Montgomery's force turned back after he was killed by cannon fire early in the battle, but Arnold's force penetrated further into the lower city. Arnold was injured early in the attack, and Morgan led the assault in his place before he became trapped in the lower city and was forced to surrender. Arnold and the Americans maintained an ineffectual blockade of the city until spring, when British reinforcements arrived.

The siege of Fort St. Jean (September 17 – November 3, 1775 French: Siège du Fort Saint-Jean) was conducted by American Brigadier General Richard Montgomery on the town and fort of Saint-Jean, also called St. John, St. Johns, or St. John's, in the British province of Quebec during the American Revolutionary War. The siege lasted from September 17 to November 3, 1775.

After several false starts in early September, the Continental Army established a siege around Fort St. Jean. Beset by illness, bad weather, and logistical problems, they established mortar batteries that were able to penetrate into the interior of the fort, but the defenders, who were well-supplied with munitions, but not food and other supplies, persisted in their defence, believing the siege would be broken by forces from Montreal under General Guy Carleton. On October 18, the nearby Fort Chambly fell, and on October 30, an attempt at relief by Carleton was thwarted. When word of this made its way to St. Jean's defenders, combined with a new battery opening fire on the fort, the fort's defenders capitulated, surrendering on November 3.
