Myth vs. what happened

The myth

The Battle of Bunker Hill was fought on Bunker Hill.

What happened

It was mostly fought on Breed's Hill. The plan was to fortify Bunker Hill, the higher hill further back from the water, but the colonists built their main position on Breed's Hill instead. It was lower, but closer to Boston, which made it more threatening to the British and more dangerous for the colonists.

The myth

A commander shouted, "Don't fire until you see the whites of their eyes."

What happened

Whether those exact words were said that way is debated. The idea was real, though. The colonists had very little ammunition and could not afford to shoot early, so they waited until the British were close and made every shot count.

The myth

The British marched straight uphill because they were foolish.

What happened

It was not random stupidity. European armies often fought in tight formations, which helped commanders control troops, concentrate firepower and keep soldiers organized in chaos. The trouble was using that approach uphill, across exposed ground, against defenders behind earthworks.

The myth

Britain won, so it was a British success.

What happened

The British took the hill, but it cost them around a thousand casualties, many of them officers, against around 450 colonial losses. Armies can replace muskets and uniforms, but experienced officers are much harder to replace. It was a terrible bargain.

The myth

The colonists lost because the militia could not fight.

What happened

They broke two British assaults. By the third, they were nearly out of ammunition and many had no bayonets, so the fight turned into close combat and the defense collapsed. They lost because they ran out of ways to shoot back, not because they lost their nerve.

Why it mattered

For Britain, Bunker Hill was a warning that this rebellion would not end with one clean victory. For the colonists, it was proof that citizen soldiers could stand against British regulars, and that the siege of Boston was serious. George Washington would soon arrive to take command of the Continental Army, and the road from Bunker Hill leads toward independence.

Who's who

Colonel William Prescott: Led the work on the hill overnight and was the main officer holding Breed's Hill.
Israel Putnam: Involved in the broader defense and one of the names closely tied to the battle.
Dr. Joseph Warren: A doctor and one of the most respected Patriot leaders in Boston. He held a high rank but fought as a volunteer, and was killed during the retreat.
General Thomas Gage: The British commander in Boston.
General William Howe: Led the British attack, with professional soldiers, naval support and artillery.
