British Objective
Capture the fortified Charlestown Heights, eliminate the threat to Boston and restore control over the northern approaches to the occupied town.
Colonial Objective
Occupy and defend the heights overlooking Boston, threaten British positions and strengthen the provincial siege.
Major engagements: Breed’s Hill redoubt, adjoining breastwork, rail fence and Mystic River shoreline.
Terrain: Exposed slopes, fenced pastures, stone walls, shoreline obstacles, earthworks and village buildings.
British figures are widely accepted. The colonial figures follow General Artemas Ward’s orderly-book return; other accounts estimate approximately 140 killed and 280 wounded, with differences in casualty classification.
The British captured the heights but paid a devastating price.
The battle demonstrated that New England troops could withstand repeated assaults by British regulars from prepared positions. Although the colonists withdrew, British losses complicated future offensive planning and strengthened American determination to continue the siege.
Overview
On June 17, 1775, British infantry advanced across the slopes of Breed’s Hill under fire from New England militia entrenched above Charlestown. The defenders, commanded principally by Colonel William Prescott at the redoubt and supported by troops along the rail fence, withheld their fire until the approaching regulars came within effective musket range. The resulting volleys inflicted severe casualties and forced the British to withdraw. A second assault also failed. During a final attack, British troops captured the redoubt after the defenders’ ammunition ran critically low.
The engagement became known as the Battle of Bunker Hill, although the fiercest fighting occurred on neighboring Breed’s Hill. It was the first major pitched battle of the American Revolutionary War and one of the costliest British victories of the conflict.
The British won the battlefield. The Americans did not. However, the extraordinary losses suffered by the attackers revealed the difficulty of defeating entrenched colonial troops through direct assault. The battle’s strategic significance therefore extended beyond the possession of the hills.
Historical Background: The Siege of Boston
After Lexington and Concord
The fighting at Lexington and Concord on April 19, 1775, transformed the constitutional dispute between Great Britain and Massachusetts into armed conflict. Thousands of militiamen assembled around Boston, where General Thomas Gage commanded the British garrison.
Colonial forces established positions in Cambridge, Roxbury and surrounding communities. Their growing encirclement restricted British movement by land, although the Royal Navy continued to control the harbor.
The British Position in Boston
British regulars occupied Boston but faced the strategic disadvantage of being surrounded by hostile territory. Their officers recognized that nearby heights could be used to threaten the town and its harbor approaches.
British planners considered occupying Dorchester Heights to the south and the Charlestown Heights to the north. Control of these positions would improve the garrison’s security and potentially enable offensive operations against the provincial army.
The Provincial Decision to Fortify Charlestown
American leaders learned that British forces intended to seize the heights. The Massachusetts Committee of Safety and military commanders therefore decided to establish defensive works on the Charlestown peninsula.
Colonel William Prescott was assigned to lead a force of approximately 1,000 men on the night of June 16. The detachment included troops from Massachusetts regiments and was accompanied by officers responsible for engineering and supporting operations.
Why Breed’s Hill?
The expedition was associated with orders to fortify Bunker Hill, the higher ground farther inland. Instead, the principal redoubt was constructed on Breed’s Hill, closer to Boston.
The choice placed the colonial fortification in a position capable of threatening British operations but also exposed its defenders to artillery and infantry attack. Historians have debated whether the placement resulted from deliberate tactical judgment, confusion over orders or consultation among the officers on the peninsula.
A Fortification Built Overnight
During the night of June 16–17, soldiers worked with picks and shovels to construct an earthen redoubt approximately 120 feet square. The earthwork included defensive walls roughly four to five feet high.
By morning, the British could see the new fortification from Boston. The provincial army had challenged the garrison’s control of the surrounding heights.
Commanders & Participating Forces
The forces engaged at Bunker Hill consisted of British regular infantry and Royal Marines opposed by provincial soldiers from Massachusetts, Connecticut and New Hampshire. The colonial army had not yet developed the unified command structure later associated with George Washington’s Continental Army.
British Command
| Commander | Role | Operational Significance |
|---|---|---|
| General Thomas Gage | British commander in Boston | Authorized the operation against the Charlestown Heights |
| Major General William Howe | Field commander | Directed the principal British assault |
| Brigadier General Robert Pigot | British brigade commander | Directed attacks against the redoubt and adjoining positions |
| Brigadier General Henry Clinton | Senior British officer | Crossed to support the operation during the battle |
| Major John Pitcairn | Royal Marines officer | Participated in the assault and was mortally wounded |
| Lieutenant Colonel James Abercrombie | Grenadier commander | Led troops in the attacks and was mortally wounded |
Provincial Command
| Commander | Role | Operational Significance |
|---|---|---|
| General Artemas Ward | Overall provincial commander | Directed the army surrounding Boston |
| Colonel William Prescott | Redoubt commander | Supervised the defense of Breed’s Hill |
| General Israel Putnam | Connecticut general | Associated with fortification, reinforcement and withdrawal efforts |
| Colonel John Stark | New Hampshire commander | Defended the rail fence and Mystic River flank |
| Colonel James Reed | New Hampshire commander | Supported the rail-fence defense |
| Colonel Richard Gridley | Artillery and engineering officer | Helped plan the defensive earthworks |
| Dr. Joseph Warren | Massachusetts Patriot leader | Fought as a volunteer and was killed during the battle |
British Regiments and Formations
The British attack involved grenadiers, light infantry, line regiments and Royal Marines. Units associated with the fighting included the 5th, 38th, 43rd, 47th and 52nd Regiments of Foot, among others.
Grenadiers were selected infantry trained for demanding combat assignments. Light infantry were intended for mobility and operations requiring flexible movement. British officers attempted to employ these formations in coordinated attacks against the provincial defenses.
Massachusetts Provincial Troops
Prescott’s command formed the core of the redoubt’s defense. Other Massachusetts units contributed men to the breastwork, supporting positions and reinforcements.
These formations differed in experience, equipment and organization. Their service reflected the rapid transformation of local militia companies into an army capable of sustained operations around Boston.
New Hampshire Troops
Colonels John Stark and James Reed brought New Hampshire soldiers to the battlefield. Their men helped strengthen the American left flank near the rail fence and Mystic River.
Their arrival was particularly important because the British intended to exploit the open ground near the shoreline to turn the provincial position.
Black and Indigenous Participation
Black and Indigenous soldiers served among the New England forces. Peter Salem and Salem Poor are two of the best-known Black participants associated with the battle.
Their service must be understood within the complicated social conditions of colonial New England, where free and enslaved Black men could serve in military formations even while slavery remained legal.
Battlefield Geography & Terrain
The Charlestown peninsula consisted of hills, fenced agricultural land, roads and shoreline approaches. The British landed on its eastern side and advanced toward defensive positions occupying the higher ground.
Breed’s Hill
The principal American redoubt stood on Breed’s Hill, overlooking the British approaches from the waterfront.
Bunker Hill
Located northwest of Breed’s Hill, Bunker Hill provided higher ground along the provincial line of withdrawal toward Charlestown Neck.
The Redoubt
A roughly square earthen fortification offered protection against musket fire and served as the central defensive position.
The Breastwork
An adjoining defensive extension helped connect the redoubt to positions farther north, although gaps remained in the overall line.
The Rail Fence
Stone walls and wooden rails reinforced with available materials created a defensive position stretching toward the Mystic River.
The Mystic River Shoreline
A narrow beach offered the British a possible route around the American left, but provincial defenders blocked the approach.
Charlestown
Buildings near the southern approaches complicated British operations. Much of the settlement was destroyed by fire during the battle.
Charlestown Neck
The narrow land connection to the mainland was the principal route for reinforcement and retreat, and was exposed to British fire.
The Bunker Hill Monument stands on Breed’s Hill, near the location of the principal redoubt. The modern city bears little resemblance to the fenced agricultural landscape of 1775.
Weapons, Equipment & Logistics
British Infantry Weapons
British regulars primarily carried smoothbore flintlock muskets fitted with socket bayonets. Military drill emphasized formation movement, coordinated firing and the ability to close with an enemy through bayonet assault.
Although smoothbore muskets were capable of inflicting substantial casualties at close range, their effectiveness depended upon distance, visibility, training and the circumstances of firing.
Provincial Weapons
New England soldiers carried a mixture of military muskets and privately owned firearms. Their equipment varied, and not every defender possessed a bayonet.
The popular image of all American soldiers fighting with long rifles is misleading. Smoothbore muskets were widely used by the provincial forces.
Artillery
British artillery aboard ships and on land attempted to suppress the colonial defenses. However, terrain, firing angles and the construction of the redoubt limited the effectiveness of some bombardment.
Provincial artillery support was comparatively limited. The defenders depended primarily upon infantry fire and their earthworks.
The Ammunition Problem
One of the decisive weaknesses of the colonial position was its limited ammunition supply. The defenders had worked through the night and remained in position while British troops assembled for the assault.
After repelling repeated attacks, many soldiers had little powder or ammunition remaining. During the final British assault, the shortage greatly reduced the defenders’ ability to maintain effective fire.
Bayonets and Close Combat
British soldiers possessed a significant advantage when they reached the redoubt. Their bayonets enabled them to assault the works at close quarters, while some provincial soldiers lacked comparable weapons.
As British troops entered the fortification, the defenders were forced into a confused withdrawal, and fighting continued around the earthworks.
Intelligence & Operational Planning
British Plans to Break the Siege
General Gage and his senior officers recognized the danger posed by provincial forces occupying ground around Boston. British planning called for securing commanding heights and restoring freedom of movement outside the town.
The Provincial Preemptive Movement
Colonial leaders learned of the intended British movement and decided to fortify the Charlestown Heights first. Prescott’s detachment marched onto the peninsula during the night of June 16.
The British Discover the Redoubt
At daylight on June 17, British observers discovered the newly constructed earthwork. The garrison’s commanders met to consider their response and selected an amphibious movement followed by an infantry attack.
Howe’s Operational Plan
Howe intended to land troops at Moulton’s Point and advance against the provincial defenses. A movement along the Mystic River shoreline offered the possibility of turning the American left flank.
The plan became more difficult when New Hampshire troops reinforced the rail fence and blocked the shoreline approach.
The Colonial Command Problem
The provincial army lacked a fully integrated command structure. Prescott exercised authority at the redoubt, while Stark, Reed and other officers directed separate formations.
Reinforcements arrived unevenly. Some troops were exposed to artillery fire while attempting to cross Charlestown Neck, and communication among officers remained imperfect.
British officers knew the Americans occupied the heights but did not fully appreciate the strength of the newly reinforced northern defenses. Colonial commanders, meanwhile, could not predict the exact British assault plan or ensure that sufficient ammunition and reinforcements reached every position.

Expand each entry to follow the construction of the redoubt, the British landings, the successive assaults and the final American withdrawal. Times are approximate.
June 16, 1775
Evening — Prescott receives orders to fortify the heights
Colonel William Prescott assembles a detachment of provincial soldiers and prepares to march toward the Charlestown peninsula.
The expedition is intended to establish defensive works before British troops can occupy the strategically important ground.
Late Night — Colonial troops reach the peninsula
Prescott’s soldiers, accompanied by officers including Israel Putnam and Richard Gridley, reach the heights and begin preparing defensive works.
The principal fortification is established on Breed’s Hill rather than the higher Bunker Hill farther inland.
June 17, 1775
Approximately 12:30 a.m. — Construction begins
Provincial soldiers begin digging the redoubt with picks and shovels. The work continues through the night.
The fortification is approximately 120 feet square, with earthen walls intended to protect the defenders from infantry fire.
Daybreak — British troops discover the works
British observers in Boston identify the new colonial fortification. Naval guns begin bombarding the position.
The bombardment does not destroy the redoubt or force its defenders to abandon the hill.
Approximately 9:00 a.m. — British commanders meet
General Gage and senior officers consider how to remove the provincial forces from the heights.
Major General William Howe is assigned to command the attack. Troops begin preparing for transportation across the harbor.
Late Morning — Provincial reinforcements move toward Charlestown
Additional New England soldiers attempt to reach the peninsula. British naval and artillery fire complicates movement along the narrow approach.
Some units arrive to reinforce the defensive line, while others remain behind or become separated from the principal fighting.
Midday — British infantry land at Moulton’s Point
British troops cross from Boston in boats and land on the eastern side of Charlestown.
Howe organizes his infantry for an assault against the provincial defenses. The operation requires troops to advance uphill across exposed and uneven ground.
Early Afternoon — Stark and Reed strengthen the American left
New Hampshire troops under Colonels John Stark and James Reed occupy positions near the rail fence and Mystic River.
They strengthen the defensive line with available fencing, stone walls and other materials.
Their deployment helps block the British plan to advance along the shoreline and turn the provincial flank.
Approximately 3:30 p.m. — The first British assault
British infantry begin advancing against the American defenses. One force approaches the rail fence and Mystic River shoreline while other troops threaten the redoubt and breastwork.
The provincial defenders hold their fire until the attackers reach effective range.
Concentrated musket volleys inflict heavy casualties among the advancing regulars. British formations lose cohesion and withdraw to reorganize.
Mid-Afternoon — The second British assault
Howe’s troops regroup and renew their attack. The British again advance against the entrenched provincial line.
The Americans maintain their defensive positions and deliver destructive fire at close range.
The second assault also fails to dislodge the defenders. British casualties continue to mount, including substantial losses among officers.
Later Afternoon — The final assault begins
British commanders reorganize their forces and concentrate greater effort against the redoubt and adjoining works.
By this stage, many provincial defenders have exhausted much of their ammunition.
The British advance under fire, close with the redoubt and prepare to attack with bayonets.
Final Assault — British troops enter the redoubt
British infantry reach the earthworks and force their way into the defensive position.
The defenders, increasingly unable to maintain effective musket fire, attempt to resist the assault but cannot hold against the advancing regulars.
Fighting develops at close quarters. Prescott’s men begin withdrawing from the redoubt.
Late Afternoon — Joseph Warren is killed
Dr. Joseph Warren, a leading Massachusetts Patriot who had recently received a major general’s commission, is killed during the final fighting.
Warren had chosen to serve as a volunteer rather than exercise senior command at the redoubt.
His death becomes one of the most widely remembered individual losses of the battle.
Late Afternoon — Provincial forces withdraw
After the redoubt falls, the defenders retreat across the Charlestown peninsula.
Troops from the rail-fence positions help cover the withdrawal, limiting the British ability to turn the retreat into a complete destruction of the provincial force.
Evening — British troops occupy the heights
The British secure Breed’s Hill and Bunker Hill. The provincial army withdraws to positions beyond the peninsula.
The British have captured their objective but suffered exceptionally heavy losses.
After the Battle
June 18 — Both armies assess the losses
British commanders confront the consequences of the costly assault. The provincial army remains intact outside Boston.
The British victory has not broken the siege.
July 3 — George Washington assumes command
General George Washington formally assumes command of the American army at Cambridge.
The provincial forces begin a gradual process of organizational consolidation under Continental leadership.
March 17, 1776 — British forces evacuate Boston
After American artillery occupies Dorchester Heights, British commanders decide to evacuate Boston.
The Siege of Boston ends with the departure of British troops and Loyalist civilians.
Tactical Analysis & Command Decisions
Why the British Attacked Uphill
The British command sought to remove the provincial forces from ground overlooking Boston. An infantry assault offered the possibility of rapidly restoring control of the heights.
However, the attack required soldiers to cross uneven terrain under fire from protected defenders. Fences, slopes and obstacles disrupted movement and reduced the ability of the attackers to maintain perfectly aligned formations.
The Advantage of the Redoubt
The earthen walls on Breed’s Hill gave the defenders substantial protection against incoming musket fire. The British, by contrast, had to advance across open ground before they could bring their bayonets to bear.
This imbalance favored the defenders as long as they possessed sufficient ammunition and could maintain their positions.
Controlled Fire at Close Range
The provincial defenders were instructed to conserve ammunition and avoid ineffective long-range firing.
By allowing the British to approach within effective musket range, the Americans increased the destructive effect of their volleys.
The familiar command to wait until the whites of the enemy’s eyes were visible expresses this principle, although its exact wording and attribution remain disputed.
The diagram illustrates the British approach toward the American redoubt. It is not a measured reconstruction of troop positions or assault distances.
The Failed Flanking Movement
Howe’s plan included an effort to advance along the Mystic River shoreline and turn the provincial left.
The arrival of Stark’s and Reed’s troops prevented the British from exploiting this route. Their defensive fire inflicted severe casualties and forced the attacking light infantry to withdraw.
The Second Assault
The second attack repeated many of the difficulties of the first. British troops faced concentrated fire from the redoubt and rail fence, while the defenders retained the advantage of cover.
Heavy officer casualties further complicated command and coordination.
Why the Third Assault Succeeded
The final British attack concentrated more directly against the redoubt. The defenders’ dwindling ammunition supply sharply reduced their ability to maintain effective resistance.
Once British infantry reached the earthworks, bayonets and superior close-combat equipment gave the attackers a decisive advantage.
Why the British Could Not Exploit the Victory
The British captured the heights, but the losses suffered during the assaults weakened their immediate capacity for further offensive action.
The provincial army withdrew rather than being destroyed. The British therefore achieved a local tactical victory without breaking the wider siege of Boston.
The Soldier’s Experience
Provincial Soldiers in the Redoubt
The defenders spent the night of June 16 digging earthworks and preparing for battle. Many had little opportunity to rest before British artillery began firing at daybreak.
As the British infantry advanced, the provincial soldiers faced the difficult task of conserving ammunition while remaining exposed to artillery fire and the threat of bayonet assault.
During the final attack, soldiers who had successfully repelled earlier assaults found themselves unable to maintain their fire. The withdrawal from the redoubt was therefore a consequence of both enemy pressure and exhausted supplies.
British Regulars Advancing Uphill
British infantry crossed the harbor by boat, formed for battle and advanced through difficult terrain toward fortified positions.
They encountered intense musket fire from defenders who were partly protected by earthworks and fences. Casualties were especially severe among officers and soldiers attempting to maintain formation under fire.
For the British troops, the battle combined disciplined advance, repeated withdrawal, reorganization and eventual close-quarters combat.
Peter Salem
Peter Salem was a Black soldier whose Revolutionary War service included the Battle of Bunker Hill. Later historical traditions credit him with shooting Major John Pitcairn, but the identification of the individual who fired that shot is not conclusively established by contemporary evidence.
Salem’s documented military service is important independently of the disputed attribution.

Salem Poor
Salem Poor, a formerly enslaved man who had purchased his freedom, served in the provincial forces at Bunker Hill.
His conduct attracted the attention of fellow officers, who later petitioned the Massachusetts legislature to recognize his distinguished behavior during the battle.
The petition provides unusually direct contemporary evidence of a Black soldier receiving recognition from military witnesses.
Related biography: Salem Poor.
Joseph Warren
Dr. Joseph Warren had played an important role in the Massachusetts resistance movement and had recently been appointed a major general.
Rather than assume command of the provincial forces at Breed’s Hill, he joined the defenders as a volunteer.
He was killed during the final stages of the battle. His death became an important symbol of sacrifice in Patriot accounts of the Revolution.
Related biography: Joseph Warren.
The Civilian Experience
Charlestown was heavily damaged by British artillery and fire during the battle. Homes and businesses were destroyed, and residents were displaced.
The destruction of the town illustrates the consequences of military operations for civilians who lived near the battlefield.
Where Was Your Ancestor’s Unit?
Family historians researching Bunker Hill must distinguish service in the Siege of Boston from participation in the battle on June 17, 1775.
A soldier may have served in the provincial army around Boston without having fought on Breed’s Hill, at the rail fence or during the withdrawal.

How to Verify Participation
Begin with the soldier’s town, company, regiment, commanding officer and dates of service. Compare pension declarations with contemporary muster rolls, pay abstracts and casualty returns.
When a pension declaration states that a soldier served at Bunker Hill, determine whether the testimony identifies the June 17 battle or refers more generally to service during the Siege of Boston.
Service in Massachusetts during June 1775 does not automatically establish participation in the Battle of Bunker Hill. The original record must support the specific battlefield claim.
Battle Outcome & Casualties
British Losses
British returns recorded 226 killed and 828 wounded, for 1,054 casualties. These losses represented a remarkably high proportion of the approximately 2,400 British soldiers and Marines engaged.
The losses included numerous officers, weakening the leadership of several units and contributing to the battle’s reputation as an exceptionally costly victory.
Provincial Losses
A contemporary return preserved in General Artemas Ward’s orderly book listed 115 killed, 305 wounded and 30 captured, totaling 450.
Other historical reconstructions identify approximately 140 killed and 280 wounded. Differences reflect the treatment of missing soldiers, prisoners and men who died after the battle.
| Force | Killed | Wounded | Captured | Total |
|---|---|---|---|---|
| British regulars and Marines | 226 | 828 | — | 1,054 |
| Provincial forces — Ward’s return | 115 | 305 | 30 | 450 |
The Death of Joseph Warren
Warren was among the most prominent American casualties. His death received considerable attention because of his political leadership and prominent role in the resistance movement.
British Officer Casualties
Major John Pitcairn and Lieutenant Colonel James Abercrombie were among the British officers mortally wounded. Other officers were killed or wounded during the repeated assaults.
Assessing the Result
The British captured Breed’s Hill and Bunker Hill, forcing the provincial defenders to withdraw. By the conventional standard of possession of the battlefield, the British achieved a tactical victory.
However, the British did not destroy the provincial army or break the siege of Boston. The losses suffered during the assault discouraged an immediate continuation of large-scale offensive operations against entrenched American positions.
Strategic Significance & Aftermath
A Victory Too Expensive
The Battle of Bunker Hill demonstrated the extraordinary cost of attacking prepared defenses without first neutralizing them.
British commanders gained the ground but lost more than a thousand soldiers killed or wounded. The casualties imposed a significant burden upon a garrison already confronting a large provincial army.
The Provincial Army Remains Intact
Despite losing the heights, the New England forces continued to surround Boston. The battle did not restore British freedom of movement through the Massachusetts countryside.
Washington Takes Command
On July 3, 1775, George Washington formally assumed command of the American army at Cambridge.
His arrival marked an important stage in transforming the assembled provincial forces into a more unified Continental Army.
The Siege Continues
The British retained Boston throughout the remainder of 1775. The Americans maintained the siege while attempting to improve their organization, supply system and artillery strength.
British Evacuation of Boston
In March 1776, American artillery occupied Dorchester Heights. The new position threatened British control of the harbor and contributed to the decision to evacuate Boston on March 17.
The Memory of Bunker Hill
The battle became a powerful symbol of American resistance. The death of Joseph Warren, the determination of the provincial defenders and the heavy British losses shaped later public memory.
The Bunker Hill Monument, completed and dedicated in 1843, stands on Breed’s Hill near the location of the principal redoubt.
Historical Significance
Bunker Hill established that the American rebellion would not be suppressed easily. British regulars had demonstrated their ability to capture a fortified position, but provincial soldiers had demonstrated that disciplined defensive fire could inflict severe losses upon one of Europe’s professional armies.
The battle was therefore both a British military victory and an important early demonstration of American military capability.

Research Limitations
Precise provincial troop strengths, individual regimental assignments, the movements of Israel Putnam, the origin of the famous close-range firing command and the identification of the soldier who shot Major Pitcairn remain subjects of historical discussion.
Some published casualty returns also differ in their treatment of missing men, prisoners and deaths occurring after the battle.
Documented service in the Siege of Boston, participation in the June 17 battle and presence at a particular defensive position are distinct historical claims. Individual soldier biographies should preserve these distinctions and identify the records supporting each claim.
