2.2 The American Revolution & Independence (1775–1783)

Outbreak of Hostilities and the Early War Effort (1775–1776)

The imperial crisis turned military on April 19, 1775, when British troops marched from Boston toward Lexington and Concord to seize colonial military stores and arrest rebel leaders Samuel Adams and John Hancock. Alerted by riders including Paul Revere, local Minutemen assembled on Lexington Green. An unknown shot—immortalized by Ralph Waldo Emerson as the 'shot heard 'round the world'—triggered a skirmish that left eight colonists dead. As the British retreated to Boston, thousands of militia harassed them along the road, inflicting heavy casualties.

In May 1775, the Second Continental Congress convened in Philadelphia. Acting as a provisional national government, Congress assumed responsibility for the war effort:

• Established the Continental Army and unanimously appointed George Washington of Virginia as Commander-in-Chief.
• Authorized the issuance of paper money (Continental currency) to finance military supplies.
• Drafted the Olive Branch Petition (written by John Dickinson) in July 1775 as a final effort at reconciliation, pledging loyalty to King George III and requesting an end to hostilities.

King George III refused to read the Olive Branch Petition. Instead, he issued the Proclamation of Rebellion (August 1775) and signed the Prohibitory Act (December 1775), declaring all American ships in a state of open rebellion and imposing a naval blockade. Meanwhile, colonial forces suffered severe casualties at the Battle of Bunker Hill (June 1775) near Boston, though they demonstrated that untrained militia could stand against professional British regulars.

Ideological Foundations: Common Sense and Jefferson's Declaration

At the start of 1776, many colonists still sought reconciliation while blaming Parliament rather than the King. This ideological hesitation was shattered in January 1776 by the publication of Thomas Paine's pamphlet, Common Sense.

Writing in lucid, vigorous prose accessible to ordinary citizens, Paine attacked the very institution of hereditary monarchy and royal privilege. He argued that it was absurd for a continent to be perpetually governed by an island, and that America had a moral obligation to destroy tyranny and establish a democratic republic. Common Sense sold over 120,000 copies within months, converting broad public sentiment toward absolute separation.

On June 7, 1776, Virginia delegate Richard Henry Lee introduced a resolution to Congress declaring 'that these United Colonies are, and of right ought to be, free and independent States.' Congress appointed a 'Committee of Five'—consisting of Thomas Jefferson, John Adams, Benjamin Franklin, Roger Sherman, and Robert R. Livingston—to draft a formal manifesto.

Drafted primarily by Thomas Jefferson, the Declaration of Independence was formally adopted on July 4, 1776. The document synthesized Enlightenment political theory, drawing heavily on John Locke's Second Treatise of Government:

1. Natural Rights: Asserted that all individuals possess 'unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.'
2. Social Contract & Popular Sovereignty: Maintained that governments derive their 'just powers from the consent of the governed.'
3. Right of Revolution: Held that when a government becomes destructive of these ends, it is the right of the people to alter or abolish it.
4. Grievances Against the Crown: Listed 27 explicit charges against King George III—including quartering troops, cutting off trade, and imposing taxes without consent—to justify cutting ties with Great Britain.

Tactical Turning Points: From Trenton to Saratoga

The early campaigns were perilous for Washington's army. After losing the Battle of Long Island (August 1776), British General William Howe forced Continental troops to evacuate New York City, retreating through New Jersey into Pennsylvania. With enlistments expiring and morale plummeting, Washington executed a daring counterstroke.

On Christmas night 1776, Washington led his troops across the ice-choked Delaware River, launching a surprise attack on Hessian mercenaries at the Battle of Trenton (December 26, 1776). Days later, Washington outmaneuvered British reinforcements at the Battle of Princeton (January 1777). These unexpected victories restored military confidence and saved the revolutionary cause from collapse.

The strategic turning point of the war occurred in upstate New York during the autumn of 1777. British General John Burgoyne spearheaded a three-pronged campaign to isolate New England from the rest of the colonies. However, poor coordination and fierce resistance from American forces under Generals Horatio Gates and Benedict Arnold trapped Burgoyne's army at Saratoga. On October 17, 1777, Burgoyne surrendered his entire army of nearly 6,000 men at the Battle of Saratoga.

The French Alliance and the Road to Yorktown (1778–1781)

The American victory at Saratoga had immediate international ramifications. Benjamin Franklin, serving as American ambassador in Paris, capitalized on the news to convince French Foreign Minister Comte de Vergennes that the Americans possessed the military capability to defeat Great Britain.

In February 1778, France signed two historic treaties with the United States:

• Treaty of Amity and Commerce: Recognized American independence and established trading ties.
• Treaty of Alliance: Formed a permanent defensive alliance, stipulating that neither nation would lay down arms until American independence was secured, and guaranteeing French military support.

France provided invaluable financial loans, military supplies, land forces under the Comte de Rochambeau, and naval fleets under the Comte de Grasse. Spain (1779) and the Dutch Republic (1780) subsequently entered the war against Great Britain, transforming a colonial insurrection into a global conflict that strained British resources worldwide.

During the harsh winter of 1777–1778 at Valley Forge, Pennsylvania, Washington's troops endured starvation, disease, and freezing conditions. However, Prussian officer Baron von Steuben instituted rigorous European military drill and sanitation standards, forging the Continental Army into a disciplined, professional fighting force.

Faced with deadlock in the North, Britain shifted to a Southern Strategy in 1778, hoping to leverage Loyalist support in the Carolinas and Georgia. Despite initial British victories at Charleston and Camden, American Nathanael Greene executed a war of attrition, exhausting British forces under General Charles Cornwallis.

In late 1781, Cornwallis marched his army to the Virginia peninsula at Yorktown to resupply. Washington swiftly coordinated a joint land and naval offensive. Rochambeau's army joined Washington's forces on land, while Admiral de Grasse's French fleet defeated the British navy at the Battle of the Capes, trapping Cornwallis by sea. After a three-week siege, Cornwallis surrendered on October 19, 1781, effectively ending major military operations in North America.

The Treaty of Paris (1783)

Negotiated in Paris by American commissioners John Adams, Benjamin Franklin, and John Jay, the Treaty of Paris (1783) formally concluded the Revolutionary War. Demonstrating astute diplomacy, the American envoys negotiated directly with Great Britain, bypassing French influence to secure exceptionally favorable terms:

1. Recognition of Sovereignty: Great Britain formally recognized the United States as an independent and sovereign nation.
2. Territorial Boundaries: Set expansive borders—extending north to the Great Lakes and St. Lawrence River, west to the Mississippi River, and south to the 31st parallel (the border of Spanish Florida).
3. Fisheries Rights: Granted American fishermen rights to fish off the coast of Newfoundland and Nova Scotia.
4. Debts & Loyalist Claims: Recommended that individual states restore confiscated Loyalist property and permitted British creditors to collect legitimate pre-war debts.
