In the aftermath of the failed Concord expedition, the thousands of militiamen that had converged on Boston remained. Over the next few days, more arrived from further afield, including companies from New Hampshire, Connecticut, and Rhode Island. Under the command of "Artemas Ward, they surrounded the city, blocking its land approaches and putting the occupied "city under siege. The British regulars fortified the high points in the city.
Need for supplies
While the British were able to resupply the city by sea, supplies in Boston were short. Troops were sent out to some of the islands in "Boston Harbor to raid farmers for supplies. In response, the colonials began clearing those islands of supplies useful to the British. One of these actions was contested by the British in the "Battle of Chelsea Creek, but it resulted in the loss of two British soldiers and the British ship Diana. The need for building materials and other supplies led Admiral "Samuel Graves to authorize a "Loyalist merchant to send his ships from Boston to "Machias in the "District of Maine, accompanied by a Royal Navy schooner. The Machias townspeople rose up, seizing the merchant vessels and then the schooner "after a short battle in which its commander was killed. Their resistance and that of "other coastal communities led Graves to authorize an expedition of reprisal in October whose sole significant act was the "Burning of Falmouth. The outrage in the colonies over this action contributed to the passing of legislation by the "Second Continental Congress that established the "Continental Navy.
The colonial army also had issues with supply, and with command. Its diverse militias needed to be organized, fed, clothed, and armed, and command needed to be coordinated, as each militia leader was responsible to his province's congress.
Late in May, General Gage received by sea about 2,000 reinforcements and a trio of generals who would play a vital role in the war: "William Howe, "John Burgoyne, and "Henry Clinton. They formulated a plan to break out of the city, which was finalized on June 12. Reports of these plans made their way to the commanders of the besieging forces, who decided that additional defensive steps were necessary.
On the night of June 16–17, 1775, a detachment of the colonial army stealthily marched onto the Charlestown peninsula, which the British had abandoned in April, and fortified Bunker Hill and "Breed's Hill. On June 17, British forces under General Howe attacked and seized the Charlestown peninsula in the "Battle of Bunker Hill. This battle was technically a British victory, but losses (about 1/3 the attacking forces killed or wounded, including a significant fraction of the entire British officer corps in all of North America) were so heavy that the attack was not followed up. The siege was not broken, and General Gage was recalled to England in September and replaced by General Howe as the British commander-in-chief.
Formation of the Continental Army
The "Second Continental Congress, meeting in "Philadelphia, had received reports of the situation outside Boston when it began to meet in May 1775. In response to the confusion over command in the camps there, and in response to the May 10 "capture of Fort Ticonderoga, the need for unified military organization became clear. Congress officially adopted the forces outside Boston as the "Continental Army on May 26, and named "George Washington its commander-in-chief on June 15. Washington left Philadelphia for Boston on June 21, but did not learn of the action at Bunker Hill until he reached "New York City.
Following the Battle of Bunker Hill, the siege was effectively stalemated, as neither side had either a clearly dominant position, or the will and materiel to significantly alter its position. When Washington took command of the army in July, he determined that its size had reduced from 20,000 to about 13,000 men fit for duty. He also established that the battle had severely depleted the army's "powder stock, which was eventually alleviated by powder shipments from Philadelphia. The British were also busy bringing in reinforcements; by the time of Washington's arrival the British had more than 10,000 men in the city.
Throughout the summer and fall of 1775, both sides dug in, with occasional skirmishes, but neither side chose to take any significant action. Congress, seeking to take some initiative and to capitalize on the capture of Ticonderoga, authorized an "invasion of Canada, after several "letters to the inhabitants of Canada were rejected by the French-speaking and British colonists there. In September, "Benedict Arnold led 1,100 troops on an "expedition through the wilderness of Maine, which was drawn from the army assembled outside Boston.
Washington faced a personnel crisis toward the end of 1775, as most of the troops in the army had enlistments that expired at the end of 1775. He introduced a number of recruitment incentives and was able to keep the army sufficiently large to maintain the siege, although it was by then smaller than the besieged forces.
By early March 1776, heavy cannons that had been captured at Fort Ticonderoga "were moved to Boston, a difficult feat engineered by "Henry Knox. When the guns were "placed on Dorchester Heights in the course of one day, overlooking the British positions, the British situation became untenable. While General Howe planned an attack to reclaim the high ground, a snowstorm prevented its execution. The British, after threatening to burn the city if their departure was hindered, "evacuated the city on March 17, 1776 and sailed for temporary refuge in "Halifax, "Nova Scotia. The local militias dispersed and, in April, General Washington took most of the "Continental Army to fortify "New York City and the start of the "New York and New Jersey campaign.
The British were essentially driven from New England as a result of this campaign, although there (as elsewhere in the colonies) they continued to receive support from local "Loyalists, especially in "Newport, Rhode Island, from which they drove most of the local "Patriots. The campaign, as well as the final result of the war as a whole, were a significant blow to British prestige and confidence in its military. The senior military leaders of the campaign were criticized for their actions (Clinton, for example, while he went on to command the British forces in North America, would take much of the blame for the British loss of the war), and others either saw no more action in the war (Gage), or were ultimately disgraced (Burgoyne, who surrendered his army at "Saratoga). While the British continued to control the seas, and had military successes on the ground (notably in "New York, New Jersey, and "Pennsylvania), their actions that led to these conflicts had the effect of uniting the Thirteen Colonies in opposition to the crown. As a result, they were never able to marshal enough support from Loyalists to regain meaningful political control of the colonies.
The colonies, in spite of their differences, united themselves as a consequence of these events, granting the "Second Continental Congress (predecessor to the modern "U.S. Congress) sufficient authority and funding to conduct the revolution as a unified whole, including funding and outfitting the military forces that formed as a result of this campaign.
