A significant early battle of the American Revolutionary War where colonial forces, despite eventual defeat, proved their military capability by inflicting heavy casualties on British forces in Charlestown, Massachusetts.

The Battle of Bunker Hill stands as one of the most significant early conflicts of the American Revolutionary War, taking place on June 17, 1775. Though commonly known as the Battle of Bunker Hill, most of the fighting actually occurred on nearby Breed's Hill in Charlestown, Massachusetts.

This pivotal battle marked a crucial turning point in American colonial resistance against British forces. While technically a British victory, the battle demonstrated the colonists' remarkable ability to stand against professional British troops. The heavy casualties inflicted on the British forces - including nearly half of their attacking force - proved that the colonial militia wasn't just a ragtag group of farmers but a force capable of challenging the world's most powerful military.

The Battle of Bunker Hill took place on June 17, 1775, starting at approximately 3:00 PM and lasting for three hours. Colonial forces fortified Breed's Hill on the night of June 16, constructing earthworks under Colonel William Prescott's command.

• Received intelligence of British plans to occupy Dorchester Heights at 9:00 PM
• Deployed 1,200 colonial troops to fortify the peninsula at 10:00 PM
• Constructed a 6-foot-high earthen redoubt on Breed's Hill by dawn
• Built a rail fence defense line stretching to Mystic River

Time	Event	Location
3:00 PM	First British assault begins	Breed's Hill
3:30 PM	First British assault repelled	Eastern slope
4:00 PM	Second British assault begins	Southern front
4:30 PM	Second assault defeated	Redoubt area
5:00 PM	Final British assault launched	All positions

• British naval bombardment commenced at dawn
• Colonial reinforcements arrived at 2:00 PM under Stark & Reed
• Ammunition depletion forced colonial retreat at 5:30 PM
• British secured Charlestown Peninsula by 6:00 PM

The engagement lasted precisely 2 hours 30 minutes from the first British assault to the colonial forces' withdrawal. British General Howe employed three distinct attacks to capture the colonial positions, with the third assault proving successful after the Americans exhausted their ammunition supplies.

The political tension between British forces and American colonists escalated into military action in April 1775. A series of confrontations established the backdrop for the Battle of Bunker Hill.

British military forces maintained strict control over Boston following the Boston Tea Party in December 1773. General Thomas Gage commanded 4,000 British troops who occupied the city with naval support from Admiral Samuel Graves' fleet of warships. The British army restricted movement in Boston through checkpoints, confiscated weapons from residents, and enforced the Coercive Acts passed by Parliament.

Colonial forces surrounded Boston with approximately 15,000 militiamen in May 1775. The Continental Army established defensive positions in Cambridge, Roxbury, and Dorchester Heights to contain British troops within the city. Intelligence reports indicated British plans to seize critical high ground around Boston, prompting the Committee of Safety to order Colonel William Prescott to fortify Bunker Hill with 1,200 men on June 16. The colonial troops constructed a 160-foot long redoubt on nearby Breed's Hill using picks, shovels, and entrenching tools in a single night.

The Battle of Bunker Hill involved distinct command structures on both sides, with experienced British military officers facing colonial militia leaders who demonstrated tactical capabilities despite their relative inexperience in formal warfare.

Major General William Howe led the British forces with 2,200 troops during the main assault. Under his command, Brigadier General Robert Pigot directed the left wing while Brigadier General James Abercrombie managed tactical operations. The British forces included:

• Elite Light Infantry companies specialized in skirmish tactics

• Grenadier units equipped with grenades for close combat

• Four battalions of regular infantry from the 5th, 38th, 43rd, and 52nd Regiments

• Royal Artillery units with six-pound field guns

• Royal Marines providing naval infantry support

• Dr. Joseph Warren serving as a volunteer commanding officer

• Colonel John Stark leading New Hampshire militia units

• Captain Thomas Knowlton directing Connecticut troops

• Israel Putnam coordinating reinforcement efforts

• Artillery Captain Samuel Gridley managing two field pieces

The Battle of Bunker Hill began with strategic movements in the pre-dawn hours of June 17, 1775, setting the stage for one of the Revolutionary War's bloodiest encounters. The conflict demonstrated both colonial determination and British military might through distinct phases of combat.

Colonel William Prescott's 1,200-man colonial force constructed an earthen fortification on Breed's Hill in six hours during the night of June 16-17. The redoubt measured 160 feet long by 80 feet wide with walls rising 6 feet high. The colonists enhanced their defensive position by:

• Building a breastwork extending 100 yards north from the redoubt
• Creating rail fences filled with hay across the peninsula
• Positioning artillery pieces at strategic points along the defensive line
• Establishing firing positions behind stone walls on the beach

The British launched three major assaults on the colonial positions between 3:00 PM and 5:30 PM:

First Assault:

• 1,500 British troops advanced in two columns
• Colonial defenders held fire until British reached 50-yard range
• British retreated with 97 dead and 279 wounded

Second Assault:

• Fresh troops joined the attack at 4:00 PM

• Colonists inflicted heavy casualties on advancing forces

• British artillery set Charlestown ablaze as cover

• British forces mounted successful bayonet charge at 5:30 PM

• Colonial ammunition depleted to less than 40 rounds

• Final casualty count:

Side	Killed	Wounded	Total Casualties
British	226	828	1,054
Colonial	140	271	411

The Battle of Bunker Hill transformed the American Revolution from a colonial uprising into a full-scale war. This pivotal engagement demonstrated the colonial forces' combat capabilities while revealing critical strategic insights for both sides.

The battle's aftermath reshaped the dynamics of the American Revolution in several ways:

• British military leaders recognized the colonists as a legitimate military threat after suffering 1,054 casualties
• Colonial recruitment surged as news of the battle spread throughout the colonies
• The Continental Congress established a formal Continental Army under George Washington's command
• British forces maintained control of Boston but remained cautious about future offensive operations
• American morale increased despite the tactical defeat, proving colonial militia could challenge British regulars

The battle provided valuable military insights that influenced future strategies:

British Tactical Adjustments:

• Abandoned frontal assaults against fortified positions

• Increased emphasis on naval support during coastal operations

• Modified infantry tactics to reduce casualties

• Improved coordination between artillery and infantry units
