British regulars marched from Boston to seize colonial militia supplies at Concord. At Lexington, a small band of Minutemen faced them on the common — 'the shot heard round the world' was fired, scattering the militia. Reaching Concord, the British found little powder, but at the North Bridge they were repulsed by colonial farmers. The march back to Boston became a running gauntlet as thousands of militiamen fired from behind trees, walls, and houses.

April 19, 1775 – March 17, 1776 · Northern Theater

Colonial militia surrounded the British garrison in Boston immediately after Lexington and Concord. Gen. Washington took command of the besieging Continental Army in July 1775 and spent months struggling to organize, supply, and discipline his raw force. The decisive stroke came in February 1776 when Col. Henry Knox arrived with 59 artillery pieces dragged 300 miles by oxen from captured Fort Ticonderoga. Washington secretly fortified Dorchester Heights overnight, placing cannon that commanded both the city and harbor. General Howe, recognizing his position untenable, evacuated Boston with 9,000 troops and 1,000 Loyalists on March 17.

After colonial forces fortified Breed's Hill (adjacent to Bunker Hill) overlooking Boston Harbor, British General Howe ordered three frontal assaults up the slope. Twice the redcoats were driven back with devastating losses. On the third charge, colonial powder ran out and the Patriots were forced from the hill with bayonets. The famous order 'Don't fire until you see the whites of their eyes' epitomized the disciplined American defense.

The largest battle of the entire Revolutionary War. Howe landed 20,000 British and Hessian troops on Long Island in a meticulously planned operation. While an American force held Brooklyn Heights, Howe sent Clinton on a night march through unguarded Jamaica Pass to strike the American left from behind. The encircled American units were destroyed or captured. Only desperate rearguard fighting by Maryland and Delaware troops — 'The Four Hundred' — bought time. On the night of August 29, Washington secretly evacuated 9,000 men across the East River to Manhattan, using every available boat in a thick fog.

With the Continental Army disintegrating from desertion and expiring enlistments, Washington made a desperate gamble. On Christmas night 1776, he led 2,400 soldiers across the ice-choked Delaware River in a blinding sleet storm, marching nine miles to attack the Hessian garrison at Trenton at dawn. The surprised Hessians were overwhelmed in less than an hour. Colonel Rall was mortally wounded; nearly 900 Hessians were captured.

Days after Trenton, Washington slipped away from Cornwallis's larger army at night and struck the British rear guard at Princeton. Washington himself rode forward to rally retreating troops, reportedly to within 30 yards of British muskets, before the redcoats broke. The twin victories of Trenton and Princeton sent British and Hessian forces retreating into winter quarters.

Howe landed his army south of Philadelphia and marched north. Washington chose to defend the Brandywine Creek crossing. As at Long Island, Howe sent Cornwallis on a wide flanking march through an unguarded ford. Local intelligence about the flanking column reached Washington too late and was confused by conflicting reports. Cornwallis struck the American right and rear while the main British force crossed in front. The American army was defeated but retreated in reasonable order — saved in part by a fierce counterattack by General Anthony Wayne.

Burgoyne's army, advancing south from Canada to cut off New England, collided with Gates's Continental forces at Freeman's Farm along the Hudson River. Daniel Morgan's riflemen and Benedict Arnold's aggressive counterattacks inflicted heavy casualties. Despite holding the field, Burgoyne suffered losses he could not replace, far from his supply lines.

October 7, 1777 · Northern Theater

Burgoyne made a final desperate reconnaissance in force, which American forces turned into a decisive defeat. Benedict Arnold, who had been relieved of command by Gates, rode onto the battlefield without orders and led a furious attack that stormed the Breymann Redoubt. Burgoyne's army, surrounded and out of supplies, surrendered 5,895 men on October 17th — the largest British surrender of the entire war.

December 19, 1777 – June 19, 1778 · Middle Theater

Washington's Continental Army spent the brutal winter of 1777–1778 encamped at Valley Forge, Pennsylvania, just 18 miles from British-occupied Philadelphia. Without adequate food, clothing, or shelter, approximately 2,500 soldiers died from disease, exposure, and starvation. Yet the army that emerged was transformed — Prussian drillmaster Baron Friedrich von Steuben trained the ragged troops into a professional fighting force.

When the British evacuated Philadelphia after France entered the war, Washington pursued. General Charles Lee ordered an inexplicable retreat just as battle was joined. Washington rode furiously to the front and, reportedly furious, relieved Lee on the spot and turned the retreat into a battle. The Continental Army fought the British regulars to a standstill in 100-degree heat — the professional army Valley Forge had created proved itself equal to the redcoats. Molly Pitcher legend originates here.

Brigadier General Daniel Morgan devised a tactical masterstroke against the feared Colonel Tarleton. Morgan positioned his militia in two lines in front of his regulars, ordering them to fire two volleys then deliberately fall back — feigning retreat. Tarleton's cavalry charged in pursuit, only to find the Continental regulars waiting. Morgan then executed a double envelopment — the militia rallied, the regulars held, and Tarleton's entire force was destroyed. Tarleton barely escaped with 200 cavalry.

Cornwallis won the field but at catastrophic cost — over 25% of his force. Greene used the same layered defense as Cowpens. Cornwallis fired his artillery into a melee of both armies to halt the American attack — a ruthless decision that shocked even his own officers. Cornwallis won the battle but lost the campaign: his army was too crippled to hold the Carolinas.

September 28 – October 19, 1781 · Southern Theater

Washington and the French General Rochambeau marched their combined armies 400 miles south from New York in secret. The French fleet under de Grasse defeated the British navy at the Battle of the Chesapeake, cutting off Cornwallis by sea. Surrounded by 16,000 Franco-American troops and pounded by French siege artillery, Cornwallis's position became untenable. On October 19, 1781, 8,000 British soldiers marched out to surrender — their band playing 'The World Turned Upside Down.'
