The arrival of a British naval squadron at Quebec City on 6 May 1776 constitutes one of the decisive operational episodes of the American Revolutionary War's northern theatre. Following the failed American assault of 31 December 1775 and the protracted, disease-ridden investment that followed under Brigadier General Benedict Arnold and, subsequently, Major General John Thomas, the besieged garrison under Lieutenant General Sir Guy Carleton had passed the winter in a state of siege punctuated by sporadic exchanges of artillery fire. The thawing of the St. Lawrence in late April permitted the resumption of maritime traffic to Quebec, and with it the possibility of relief from the Atlantic.

In the early days of April 1776, with the siege of Boston freshly won and the British fleet vanishing over the Atlantic horizon, General George Washington turned his attention southward. New York would almost certainly be the next theater of war, and Washington knew he had to reach it before the enemy did. But the overland route from New England to Manhattan was more than a line on a map. It was a living corridor of towns, taverns, and communities whose support for the revolutionary cause could not be taken for granted. Washington understood, perhaps better than any man alive, that this journey would serve two purposes at once: military preparation and political persuasion.

Early 1776, the city of Boston had become the focal point of agrinding strategic stalemate between the Continental Army and the British garrison under General William Howe. Since the battles of Lexington and Concord in April 1775, American forces had maintained a loose but effective siege around the city, bottling up roughly 6,000 British regulars and severalthousand Loyalist civilians within a narrow peninsula connected to the mainland by a single, fortified neck. Neither side possessed the decisive advantage needed to break the deadlock. That is until the Americans received the heavy artillery and a well-defended position.

On the night of March 4–5, 1776, George Washington executed one of the most audacious maneuvers of the entire war: the overnight fortification of Dorchester Heights. Dorchester Heights was a series of elevated hills on a peninsula to the south of Boston, overlooking both the city and its harbor. Military leaders on both sides understood the significance of this ground. Whoever controlled it could place artillery in a position to rain fire down on the town and the British ships anchored below.

On February 27, 1776, nearly five months before the Declaration of Independence was signed in Philadelphia, a brief but consequential clash of arms took placein the pine forests of southeastern North Carolina. The Battle of Moore’s Creek Bridge, fought roughly eighteen miles northwest of Wilmington near the present-day community of Currie, lasted barely three minutes. Yet its impact on the course of the American Revolution was far out of proportion to its brevity.

In January 1776, a relatively unknown English immigrant published a pamphlet that would alter the course of human history. Common Sense by Thomas Paine became the most influential political document of the American Revolution, transforming scattered colonial grievances into a unified cry for independence.

The final hours of 1775 witnessed one of the most audacious and ill-fated military operations of the American Revolution. As snow swirled through the narrow streets of Quebec City and temperatures plunged well below freezing, a ragged army of American soldiers launched a desperate assault against the fortified capital of British Canada. The attack would end in catastrophe, claiming the life of one of America's most promising generals and effectively dooming the colonial invasion of Canada.

In the early months of the American Revolution, the Southern colonies experienced violent struggles as Patriots and Loyalists clashed over the future of British rule. One such engagement, the Battle of Great Cane Brake, took place on December 22,1775, in the backcountry of South Carolina.

On December 9, 1775, an engagement at Great Bridge, Virginia, unfolded that effectively ended British royal authority in the oldest American colony. The Battle of Great Bridge, though modest in scale compared to later Revolutionary War clashes, delivered a decisive blow to Governor Lord Dunmore's efforts to maintain Crown control over Virginia and emboldened the patriot cause throughout the Southern colonies.

On a cold December day along the frozen banks of the St. Lawrence River, two weary American commanders finally met at the small village of Point-aux-Trembles, roughly twenty miles southwest of Quebec City. General Richard Montgomery, fresh from his successful capture of Montreal, arrived to find Colonel Benedict Arnold and the ragged survivors of one of the most punishing military expeditions in American history. Their handshake that day marked the beginning of a new chapter in the American invasion of Canada, transforming two struggling operations into a unified force that would soon march on the last major British stronghold in the province.
