Boston campaign in the context of "Battle of Bunker Hill"

The New York and New Jersey campaign in 1776 and the winter months of 1777 was a series of American Revolutionary War battles for control of the Port of New York and the state of New Jersey, fought between British forces under General Sir William Howe and the Continental Army under General George Washington. Howe was successful in driving Washington out of New York, but overextended his reach into New Jersey, and ended the New York and New Jersey campaign in January 1777 with only a few outposts near New York City under British control. The British held New York Harbor for the rest of the Revolutionary War, using it as a base for expeditions against other targets.

Landing unopposed on Staten Island on July 3, 1776, Howe had assembled an army that included components that had withdrawn from Boston in March following the British failure to hold that city, combined with additional British troops, and Hessian troops hired from several German principalities. Washington's Continental Army included New England soldiers and regiments from the Thirteen Colonies as far south as the Colony of Virginia. Landing on Long Island in August, Howe defeated Washington in the largest battle of the war in North America, but the Continental Army was able to regroup and make an orderly and covert retreat to Manhattan that night under a cover of darkness and fog. Washington suffered a series of further defeats in Manhattan but prevailed in a skirmish at the Battle of Harlem Heights and eventually withdrew his troops successfully to White Plains, New York. Howe, meanwhile, returned to Manhattan and captured those forces Washington had left on the island.

The Continental Congress was a series of legislative bodies, with some executive function, who acted as the Provisional Government for the Thirteen Colonies of Great Britain in North America, and the newly declared United States before, during, and after the American Revolutionary War. The Continental Congress refers to both the First and Second Congresses of 1774–1781 and at the time, also described the Congress of the Confederation of 1781–1789. The Confederation Congress operated as the first federal government until being replaced following ratification of the U.S. Constitution. Until 1785, the Congress met predominantly at what is today Independence Hall in Philadelphia, though it was relocated temporarily on several occasions during the Revolutionary War and the fall of Philadelphia.

The First Continental Congress convened in Philadelphia in 1774 in response to escalating tensions between the colonies and the British, which culminated in passage of the Intolerable Acts by the British Parliament following the Boston Tea Party. The First Congress met for about six weeks, mainly to try to repair the fraying relationship between Britain and the colonies while asserting the rights of colonists, proclaiming and passing the Continental Association, which was a unified trade embargo against Britain, and successfully building consensus for establishment of a second congress. The Second Continental Congress convened in 1775, soon after hostilities broke out in Massachusetts. Soon after meeting, the Second Congress sent the Olive Branch Petition to King George III, established the Continental Army, and elected George Washington commander of the new army. After the king issued the Proclamation of Rebellion in August 1775 in response to the Battle of Bunker Hill, some members of the Second Congress concluded that peace with Britain would not be forthcoming, and began working towards unifying the colonies into a new nation. The body adopted the Lee Resolution for Independence on July 2, 1776, and the Declaration of Independence two days later, on July 4, 1776, proclaiming that the former colonies were now independent sovereign states.

The southern theater of the American Revolutionary War was the central theater of military operations in the second half of the American Revolutionary War, 1778–1781. It encompassed engagements primarily in Virginia, Georgia, North Carolina, and South Carolina. Tactics consisted of both strategic battles and guerrilla warfare.

During the first three years of the conflict, 1775–1778, the largest military encounters between Continental Army and the British Army had been in the New England and Middle colonies, around Boston, New York, and Philadelphia. After the failure of the Saratoga campaign, the British Army largely abandoned operations in the north and pursued peace through control of the Southern Colonies. Before 1778, these colonies were largely dominated by Patriot-controlled governments and militias, although there was also a Continental Army presence that played a role in the 1776 defense of Charleston, the suppression of Loyalist militias, and attempts to drive the British from strongly Loyalist East Florida.

Major General Nathanael Greene (August 7, 1742 – June 19, 1786) was an American military officer and planter who served in the Continental Army during the Revolutionary War. He emerged from the war with a reputation as one of George Washington's most talented and dependable officers and is known for his successful command in the Southern theater of the conflict.

Born into a prosperous Quaker family in Warwick, Rhode Island, Greene became active in the colonial opposition to British revenue policies in the early 1770s and helped establish the Kentish Guards, a state militia unit. After the April 1775 Battles of Lexington and Concord, the legislature of Rhode Island established an army and appointed Greene to command it. Later in the year, Greene became a general in the newly established Continental Army. Greene served under George Washington in the Boston campaign, the New York and New Jersey campaign, and the Philadelphia campaign before being appointed quartermaster general of the Continental Army in 1778.
