The Battle of Bunker Hill was a significant early confrontation in the American Revolutionary War, occurring during the siege of Boston. Although the battle was fought primarily on Breed's Hill, it has been named after Bunker Hill due to its proximity and strategic importance. On June 17, colonial militias fortified positions at the top of the hill in preparation for an imminent British assault. Led by Colonel William Prescott, the colonial forces were determined to defend their territory against a vastly experienced British army. General William Howe commanded the British troops, sending them uphill in multiple waves to dislodge the entrenched Americans.

The confrontation began in the early morning and saw fierce fighting. The British forces faced heavy resistance from the colonial militia, who were instructed to conserve ammunition and fire only when they could see the whites of their enemies' eyes. As the battle progressed, the colonists inflicted significant casualties on the British troops, showcasing their resolve and tactical ingenuity despite being outnumbered and less experienced.

Ultimately, the British succeeded in taking the hill after the Americans ran low on ammunition and were forced to retreat, thus claiming a tactical victory. However, the heavy casualties suffered by the British, with over 1,000 men lost compared to approximately 450 American casualties, signaled that the colonial forces could stand up to the British army. The bravery displayed at Bunker Hill became a rallying point for the colonies and helped to galvanize support for the revolutionary cause.
