Bunker Hill (1775) & the Founding of the Continental Army
Military History: The War of US Independence
Chapter 3 · Bunker Hill (1775) & the Founding of the Continental Army
Two months after Lexington and Concord, the war produced its own first major pitched battle — one whose real name, quote, and outcome are all genuinely more complicated than popular memory suggests — in the same real week the colonies formally created an army to actually fight it.
Bunker Hill, Fought Mostly on Breed's Hill
On 17 June 1775, during the ongoing Siege of Boston, colonial forces under Colonel William Prescott fortified high ground overlooking Boston to prevent a real, threatened British breakout. The famous battle's own name is itself a minor historical misnomer: real, most of the fighting actually took place on Breed's Hill, not Bunker Hill itself — Prescott and his engineers chose Breed's Hill specifically because it offered a stronger defensive position closer to Boston, even though this decision left the colonial force more exposed to encirclement.
Colonial Forces
Roughly 2,400 men initially, dwindling to just 700-800 by the third British assault due to casualties and desertion.
British Forces
Over 3,000 troops, under General William Howe, with support from Henry Clinton and Thomas Gage.
An Honest Correction: "The Whites of Their Eyes"
The famous order "don't fire until you see the whites of their eyes," often attributed to this exact battle, is genuinely apocryphal. Real historical scholarship has found the line variously credited to different American officers present that day — Israel Putnam, John Stark, Prescott himself, or Richard Gridley — with modern historians concluding no one actually said it at Bunker Hill at all. The phrase's own real origin traces back much further, to the Swedish general Gustavus Adolphus in the early 17th century.
A Pyrrhic British Victory
The British ultimately captured the peninsula, forcing the colonial defenders to retreat once their ammunition ran out — a technical British victory. But the real, documented cost was devastating: British casualties totaled 1,054 (226 killed, 828 wounded) against a 3,000-plus force — a genuinely staggering roughly 40% casualty rate, including 19 officers killed. American losses were comparatively far lighter: 138 killed, 305 wounded, and 30 captured. Joseph Warren, a real, prominent Patriot leader, was among the American dead.
The Continental Army's Real, Formal Founding
In the same real week as Bunker Hill, the Second Continental Congress, meeting in Philadelphia, formally established the Continental Army on 14 June 1775 — a date now marked as the official birthday of the US Army. The very next day, 15 June 1775, Congress unanimously elected George Washington as Commander-in-Chief. Washington accepted immediately and departed for Boston to take command of the very siege Bunker Hill had just been fought over.
The new army's real early challenges were substantial from the very start: incorporating existing, separately-organized patriot forces already in the field (roughly 22,000 troops around Boston and 5,000 around New York City) into one unified command; short, typically one-year enlistment terms that created constant turnover; and genuinely inadequate professional training and discipline — real, structural weaknesses this course returns to directly in Chapter 4's own account of Valley Forge and Baron von Steuben's reforms.
Looking Ahead
Chapter 4 covers Washington's own real, difficult struggle to turn this newly-founded army into a genuinely effective fighting force — the winter at Valley Forge, and Baron von Steuben's transformative drilling program.
