The Western theater of the American Revolutionary War (1775–1783) was the area of conflict west of the Appalachian Mountains, the region which became the Northwest Territory of the United States as well as the states of Kentucky, Tennessee, and Missouri. The western war was fought primarily between American Indians with their British allies in Detroit, and American settlers south and east of the Ohio River.


When the American Revolutionary War began in 1775, the Ohio River marked a tenuous border between the American colonies and the American Indians of the Ohio Country. This border had its origins in the Proclamation of 1763, which forbade British colonists from settling west of the Appalachian Mountains. The British Crown had issued the Proclamation after the French and Indian War (1754–1763) in order to prevent conflict between Indians and colonists in the vast territory newly acquired from France. Settlers and land speculators in Britain and America objected to this restriction, however, and so British officials negotiated two treaties with American Indians in 1768—the Treaty of Fort Stanwix and the Treaty of Hard Labour—which opened up land for settlement south of the Ohio River. Thereafter, tensions between British officials and colonists over western land policy diminished.[2]

Most of the Indians who actually lived and hunted in the Ohio Valley—Shawnees, Mingos, Delawares, and Wyandots—had not been consulted in the 1768 treaties. Angry with the Iroquois for selling their lands to the British, Shawnees began to organize a confederacy of western Indians with the intention of preventing the loss of their lands.[3] British and Iroquois officials worked to diplomatically isolate the Shawnees from other Indian nations, however, and so when Dunmore's War broke out in 1774, Shawnees faced the Virginia militia with few allies. After Virginia's victory in the war, the Shawnees were compelled to accept the Ohio River boundary. Shawnee and Mingo leaders who did not agree with these terms renewed the struggle soon after the American Revolutionary War began in 1775.

1775 to 1776 – Neutrality and small raids[]

Initially, both the British and the Continental Congress sought to keep western American Indians out of the war. At Fort Pitt in October 1775, American and Indian leaders reaffirmed the boundary established by Dunmore's War the previous year. Without British support, Indian leaders such as Chief Blackfish (Shawnee) and Pluggy (Mingo) raided into Kentucky, hoping to drive the settlers out. Governor Patrick Henry of Virginia wanted to retaliate by attacking Pluggy's Town in the Ohio Country, but he canceled the expedition for fear that the militia would be unable to distinguish between neutral and hostile Indians, and thus make enemies of the neutral Delawares and Shawnees. Nevertheless, Shawnees and Delawares became increasingly divided over whether or not to take part in the war. While leaders such as White Eyes (Delaware) and Cornstalk (Shawnee) urged neutrality, Buckongahelas (Delaware) and Blue Jacket (Shawnee) decided to fight against the Americans.

In Kentucky, isolated settlers and hunters became the frequent target of attacks, compelling many to return to the East. By late spring of 1776, fewer than 200 colonists remained in Kentucky, primarily at the fortified settlements of Boonesborough, Harrodsburg, and Logan's Station.[4] In December 1776, Pluggy was killed in an Attack on McClellan's Station,[5] which was located on the site of present Georgetown, Kentucky.[6]

1777 – Escalation[]

In 1777, the British launched a major offensive from Canada. In order to provide a strategic diversion for operations in the Northeast, officials in Detroit began recruiting and arming Indian war parties to raid American settlements.[7] Unknown numbers of American settlers in present Kentucky, West Virginia, and Pennsylvania were killed in these raids. The intensity of the conflict increased after enraged American militiamen murdered Cornstalk, the leading advocate of Shawnee neutrality, in November 1777. Despite the violence, many Ohio Indians still hoped to stay out of the war. This was a difficult task because they were located directly between the British in Detroit and the Americans along the Ohio River.

1778 to 1779 – American advances[]

In the early years of the war, the Virginians had attempted to defend their western border with militiamen garrisoning three forts along the Ohio River—Fort Pitt, Fort Henry, and Fort Randolph. Defending such a long border proved to be futile, however, because American Indians simply bypassed the forts during their raids. In 1778, the Americans decided that offensive operations were necessary to secure their western border.

Problems at Fort Pitt[]

The first American expedition into the Ohio Country was a debacle. In February 1778, General Edward Hand led 500 Pennsylvania militiamen from Fort Pitt on a surprise winter march towards Mingo towns on the Cuyahoga River, where the British stored military supplies which they distributed to Indian raiding parties. Adverse weather conditions prevented the expedition from reaching its objective, however. On the return march, some of Hand's men attacked peaceful Delaware Indians, killing one man and a few women and children, including relatives of the Delaware chief Captain Pipe. Because only non-combatants had been killed, the expedition became derisively known as the "squaw campaign".[8]

Besides unruly militia, Loyalist sentiment around Pittsburgh also contributed to Hand's problems. In March 1778, three men with close ties to the British and American Indians left Pittsburgh, defecting to the British and Indian side. They were Simon Girty, an interpreter who had guided the "squaw campaign", Matthew Elliot, a local trader, and Alexander McKee, an agent for the British Indian Department.[9] All three would prove to be valuable British operatives in the war. Amid much criticism, and facing a congressional investigation for allowing the men to defect, Hand resigned in May 1778.[10]

Treaty making and fort building[]

Following the escalation of the war in 1777, Americans on the western frontier appealed to the Continental Congress for protection. After an investigation, a Congressional commission recommended in early 1778 that two regiments of the Continental Army be stationed in the West. Furthermore, because a defensive line of forts had little effect on Indian raids into the American settlements, the commissioners called for a fort to be built on the Indian side of the Ohio River, the first in a line of forts which would enable the Americans, it was hoped, to mount an expedition against Detroit.

Hollidays Cove Fort was a Revolutionary War fortification constructed in 1774 by soldiers from Ft. Pitt. It was located in what is now downtown Weirton, West Virginia, along Harmons Creek (named for Harmon Greathouse), about three miles from its mouth on the Ohio River. It was commanded by Colonel Andrew Van Swearingen (1741–1793) and later by his son-in-law, Captain Samuel Brady (1756–1795), the famous leader of Brady's Rangers. In 1779, over 28 militia were garrisoned at Hollidays Cove. Two years earlier, Colonel Van Swearingen led a dozen soldiers by longboat down the Ohio to help rescue the inhabitants of Ft. Henry in Wheeling in a siege by the British and Indian tribes in 1777. That mission was memorialized in a WPA-era mural painted on the wall of the Cove Post Office by Charles S. Chapman (1879–1962). The mural features Col. John Bilderback, who later gained infamy as the leader of the massacre of the Moravian Indians in Gnadenhutten in 1782.[11]

In order to build a fort in the Ohio Country, the Americans sought the approval of the Delaware Indians. In September 1778, Americans negotiated the Treaty of Fort Pitt with the Delawares, which resulted in the building of Fort Laurens along the Tuscarawas River. American plans soon went awry, however. White Eyes, the Delaware leader who had negotiated the treaty, was apparently murdered in 1778 by American militiamen. His rival, Captain Pipe, eventually abandoned the American alliance and moved west to the Sandusky River, where he began receiving support from the British in Detroit.[12] Furthermore, because of intense warfare in eastern Pennsylvania and upstate New York, Congress was unable to provide the manpower for operations against Detroit. Fort Laurens was abandoned in 1779.

Clark's Illinois campaign[]

In late 1778, George Rogers Clark, a young Virginia militia officer, launched a campaign to seize the sparsely garrisoned Illinois Country from the British. With a company of volunteers, Clark captured Kaskaskia, the chief post in the Illinois Country, on July 4, 1778, and later secured the submission of Vincennes. Vincennes was recaptured by General Henry Hamilton, the British commander at Detroit. In February 1779, Clark marched to Vincennes in a surprise winter march and captured Hamilton himself.

To American frontiersmen, Hamilton was known as "the Hair-buyer General" because, they believed, he encouraged Indians to kill and scalp American civilians. For this reason, Governor Thomas Jefferson brought Hamilton to Williamsburg, Virginia, to be tried as a war criminal. After British officials threatened to retaliate against American prisoners of war, Jefferson relented, and Hamilton was exchanged for an American prisoner in 1781.[13]

1780 – Major British and Indian offensive[]

Battle of Saint Louis (1780)

Over the next several years of the war, both sides launched raids against each other, usually targeting settlements. In 1780, hundreds of Kentucky settlers were killed or captured in a British-Indian expedition into Kentucky.[14] George Rogers Clark responded by leading an expedition in August 1780 which destroyed two Shawnee towns along the Mad River, but doing little damage to the Indian war effort.[15]

In late May Spanish-held St. Louis was attacked by a British force mostly made up of Indians and was successfully defended by the mixed Spanish and French creole force. Fort San Carlos, a stone tower in modern downtown St Louis, was the center of this defense.[16]

In the Illinois territory, French officer Augustin de La Balme assembled a militia force of French residents in an effort to take Fort Detroit. The force was destroyed in November by the Miami under Chief Little Turtle. At the same time, the nearly abandoned Fort St. Joseph was raided by Americans from Cahokia. On their return trip, however, they were overtaken by British loyalists and Indians near Petit fort.


Spanish Governor Francisco Cruzat, in St. Louis, sent a force of about 140 Spanish soldiers and American Indians under Captain Eugenio Pourré to capture Fort St. Joseph.[17] It was captured and plundered on February 12, 1781.[18]

Joseph Brant's attack on Col. Lochry (1781) ended George Rogers Clark's plans to attack Detroit.

In late 1780, Clark traveled east to consult with Thomas Jefferson, the governor of Virginia, about an expedition in 1781. Jefferson devised a plan which called for Clark to lead 2,000 men against Detroit. Recruiting enough men was a problem, however. In time of war, most militiamen preferred to stay close to their homes rather than go on extended campaigns. Furthermore, Colonel Daniel Brodhead refused to detach the men because he was staging his own expedition against the Delawares, who had recently entered the war against the Americans.[19] Brodhead marched into the Ohio Country and destroyed the Delaware Indian capital of Coshocton in April 1781, but this only made the Delawares more determined enemies and deprived Clark of badly needed men and supplies for the Detroit campaign.[20] Most of the Delawares fled to the militant towns on the Sandusky River.[21]

When Clark finally left Fort Pitt in August 1781, he was accompanied by only 400 men. On August 24, 1781, a detachment of one hundred of his men was ambushed near the Ohio River by Indians led by Joseph Brant, a Mohawk leader temporarily in the west. Brant's victory ended Clark's efforts to move against Detroit.

Between the combatants on the Sandusky River and the Americans at Fort Pitt were several villages of Christian Delawares. The villages were administered by the Moravian missionaries David Zeisberger and John Heckewelder. Although non-combatants, the missionaries favored the American cause and kept American officials at Fort Pitt informed about hostile British and Indian activity. In response, in September 1781, Wyandots and Delawares from Sandusky forcibly removed the Christian Delawares and the missionaries to a new village (Captive Town) on the Sandusky River.[22]

1782 – "The Year of Blood"[]

In March 1782, 160 Pennsylvania militiamen under Lieutenant Colonel David Williamson rode into the Ohio Country, hoping to find the Indian warriors who were responsible for ongoing raids against Pennsylvania settlers. Enraged by the gruesome murder by Indians of a white woman and her baby,[23] Williamson's men detained about 100 Christian Delawares at the village of Gnadenhütten. The Christian Delawares had returned to Gnadenhütten from Captive Town in order to harvest the crops that they had been forced to leave behind. Accusing the Christian Indians of having aided Indian raiding parties, the Pennsylvanians killed the 100 Christian Indians—mostly women and children—with hammer blows to the head.[24]

Colonel William Crawford of the Continental Army came out of retirement to lead 480 volunteer militiamen, mostly from Pennsylvania, deep into American Indian territory, with the intention of surprising the Indians. The Indians and their British allies from Detroit had learned about the expedition in advance, however, and brought about 440 men to the Sandusky to oppose the Americans. After a day of indecisive fighting, the Americans found themselves surrounded and attempted to retreat. The retreat turned into a route, but most of the Americans managed to find their way back to Pennsylvania. About 70 Americans were killed; Indian and British losses were minimal.

During the retreat, Colonel Crawford and an unknown number of his men were captured. The Indians executed many of these captives in retaliation for the Gnadenhütten massacre earlier in the year, in which about 100 Indian civilians were murdered by Pennsylvania militiamen. Crawford's execution was particularly brutal: he was tortured for at least two hours before being burned at the stake. The failure of the Crawford expedition caused alarm along the American frontier, as many Americans feared that the Indians would be emboldened by their victory and launch a new series of raids.[25] Even more defeats for the Americans were yet to come, and so for Americans west of the Appalachian Mountains, 1782 became known as the "Bloody Year".[26] On July 13, 1782, the Mingo leader Guyasuta led about 100 Indians and several British volunteers into Pennsylvania, destroying Hannastown and killing nine and capturing twelve settlers.[27] It was the hardest blow dealt by Indians in Western Pennsylvania during the war.[28]

In Kentucky, the Americans went on the defensive while Caldwell, Elliott, and McKee with their Indian allies prepared a major offensive. Fort Estill was attacked by Wyandot Indians in March 1782. Colonel Benjamin Logan, commanding officer of the region, and stationed at Logan's Station, learned that the Wyandot warriors were in the area on warpath. The Indians, aided by the British in Detroit, had raided from Boonsborough past Estill's Station along the Kentucky River. Logan dispatched 15 men to Captain Estill at Estill's Station with orders to increase his force by 25 more men and reconnoiter the country to the north and east. Following orders, Captain Estill reached the Kentucky River a few miles below the mouth of Station Camp Creek and camped that night at Sweet Lick, now known as Estill Springs. On the day after they left Estill's Station, a body of Indians appeared there at dawn on March 20, they raided the fort, scalped and killed a Miss Innes in sight of the fortification and took Monk, a slave of Captain Estill, and killed all the cattle. As soon as the Indians retreated, Samuel South and Peter Hackett, both young men, were dispatched to take the trail of the men and inform them of the news. The boys found them near the mouth of Drowning Creek and Red River early on the morning of March 21.[29] Of the 40 men, approximately 20 had left families within the fort. They returned with the boys to Estill's Station. The remainder crossed the Kentucky river and found the Indian trail. Captain Estill organized a company of 25 men, followed the Indians, and suffered what is known as Estill's Defeat, later known as the Battle of Little Mountain (March 22, 1782) in Montgomery Co.

In July 1782, more than 1,000 Indians gathered at Wapatomica, but the expedition was called off after scouts reported that George Rogers Clark was preparing to invade the Ohio Country from Kentucky. The reports turned out to be false, but Caldwell still managed to lead 300 Indians into Kentucky and deliver a devastating blow at the Battle of Blue Licks in August. With peace negotiations between the United States and Great Britain making progress, Caldwell was ordered to cease further operations.[30] Similarly, General Irvine had gotten permission for a Continental Army expedition into the Ohio Country, but this was cancelled. In November, George Rogers Clark delivered the final blow in the Ohio Country, destroying several Shawnee towns, but inflicting little damage on the inhabitants.[31]

Peace and legacy[]

The war in the Northwest, in the words of historian David Curtis Scaggs, "ended in a stalemate".[1] In the war's final years, each side could destroy enemy settlements, but could not stay and hold the territory. For the Shawnees, the war was a loss: the Americans had successfully defended Kentucky and increased settlement there, so that prime hunting ground was now lost.[32] Although the Indians had been pushed back from the Ohio River and were now settled primarily in the Lake Erie basin, the Americans could not occupy the abandoned lands for fear of Indian raids.[1]

News of the pending peace treaty arrived late in 1782. In the final treaty, the Ohio Country was signed away by Great Britain to the United States, even though "not a single American soldier was north of the Ohio River when the treaty was signed".[1] Great Britain had not consulted the Indians in the peace process, and the Indians were nowhere mentioned in treaty's terms.[33] For the Indians, the struggle would soon continue as the Northwest Indian War, though this time without the explicit support of the British.[34]
