Map Description

Scan of an old map on yellowed paper. A title written between illustrations of trees near the bottom middle reads, "A map of the country on the Ohio & Muskingum Rivers showing the situation of the Indian towns with respect to the Army under the Command of Colonel Bouquet, by Thos. Hutchins Asst. Engineer." Along the top of the map is the southern shore of Lake Erie, and near the middle the Ohio River flows diagonally toward the bottom-left corner. Near the bottom-right corner, the words "Pensilvania," "Maryland," and "Virginia" indicate the relative locations of those states. The map mostly depicts a tangle of river and creek drainages between Lake Erie and the Ohio River. From left to right, some of the major rivers and creeks on the map include the Miamis, Sioto, Hockhocking, and Muskingum Rivers, Big Beaver Creek, and the crooked, convergent drainages of the Allegheny, Monongahela, Yoxhio Geni Rivers. About 20 named towns and forts are sprinkled around the map, represented by clusters of two or three small triangles or single rectangles for forts. Other notes indicate the width of certain streams, and the presence of hills, ridges, and a few roads. Near the top center, the "Cayahoga" River is shown flowing into Lake Erie. Two labeled villages, "Cayahoga T." and "Ottawas T." are shown along the eastern shore of its U-shaped path.

“The western focus was not upon a war of independence from Great Britain as much as a war for the opportunity to gain land.” Historian Jason Edwin Anderson

The American Revolution in the Ohio Country was a complex, multi-sided conflict. To the colonists, the Ohio Country represented opportunity: freedom from British control and a chance to shape a new life. That vision collided with Tribal Nations, whose stewardship traditions clashed with colonial ideals of private ownership and land division. The outcome sped up tribal displacement, led to the creation of the Northwest Territory, and paved the way for Ohio statehood and mass European American settlement. Ultimately, it transformed the landscape. This era marked the beginning of the world we inhabit today. With hindsight, we can acknowledge both the progress and the losses, drawing lessons from history.

This article provides an overview of this extremely complicated and poorly understood period, highlighting key events. Use the many links to deepen your understanding and plan your visit to sites that help tell the story. As you explore, consider why individuals from diverse backgrounds, speaking many languages, were here in this contested land. How did they communicate? Who could they trust? What were they willing to fight and die for?

When and Where

The period of the American Revolution in the Ohio Country starts with the end of the French and Indian War in 1763 and ends with the removal of Native American tribes after the War of 1812. The usual dates given for the American Revolution are 1775–1783. These are centered around the conflict in the Eastern United States. The revolution in the Ohio Country does not fit neatly into this timeline. Large scale battles were few and most of the fighting was skirmishes. The traditional interpretation of the American Revolution is that fighting ended when British Lieutenant General Cornwallis surrenders his army at Yorktown in 1781. However, this was when hostilities in the Western Theater intensified.

Neither does the Ohio Country fit neatly within the existing state borders of Ohio. Instead, the Ohio Country was a large region west of the Appalachian Mountains and south of Lake Erie. It included all of what is now Ohio, and parts of Indiana, Pennsylvania, and West Virginia. The area was difficult for any one group to control due to its vast size and remote location. These factors, along with the many languages of its multi-ethnic population, meant the Ohio Country was slow to receive news and trustworthy information from the East. The Ohio Country was considered a remote backwater of the war. However, the outcome here was critical to the American revolutionaries’ dreams of prosperity and westward expansion.

Competing Interests

The Ohio Country during the period of the American Revolution was shaped by the actions of people driven by diverse interests. American colonists viewed the region as a land of opportunity for settlement and agriculture. For Native American nations, the war was for the survival of their cultures. If the colonists lost, they could retreat east of the Appalachians. If the British lost, they could return to Canada or Great Britain. For Native Americans, defeat meant loss of their communities and forced relocation to lands occupied by other Tribes.

Before the American Revolution, the Native American alliances with Europeans changed frequently as Great Britain and France fought for control of the fur trade and the western lands associated with it. When Great Britain finally won the French and Indian War in 1763, it tried to recoup some of the enormous cost of that war through taxes and tighter control of the western lands. However, the American colonists pushed west into Native American lands. Their actions touched off years of conflict where colonists took from Native Americans, Native Americans responded, colonists retaliated, and the cycle repeated itself.

During the American Revolution, the British tried to reassert control within the Ohio County. They relied on alliances with Native American nations to disrupt colonial expansion. For these Native Americans, the British were a temporary ally against immediate threats, despite posing long-term risks. British forces, stretched thin across an ocean and a mountain range, depended on Native American support to operate in the region. Ultimately, Native Americans bore the greatest cost in this struggle in terms of population loss and forced removal to distant reservations.

Timeline of Events

Use this timeline and its links to explore the key events that impacted the Ohio Country during this period.

1760 – France surrenders its military posts in the Great Lakes.

The French and Indian War in North America is part of Europe’s Seven Years’ War. As the conflict winds down in the Ohio Country, the British replace the French as controllers of the fur trade and trading goods, with both the French and their Native American allies losing. The British begin withholding knives, guns, powder, razors, and other trade goods from Native Americans in this region.

1763 – French and Indian War officially ends.

On February 10, the Treaty of Paris ends the French and Indian War in North America and the Seven Years’ War in Europe. France gives up its claims to mainland North America, east of the Mississippi, excluding New Orleans. Great Britain becomes the only colonial power.

In spring, the Resistance of 1763 begins. Also called Pontiac’s Rebellion, this is an attempt by Native Americans to drive the British off their land and retain control of the Ohio Country.

On October 7, the British issue the Proclamation of 1763 to stop colonists from expanding west of the Appalachian Mountains. They have two main goals. The first is to reduce conflict with Tribes in the Ohio Country. Second, the British want to keep colonists along the eastern seaboard where they can be taxed to pay for British debt from the French and Indian War.

1768 – Treaty of Fort Stanwix

On November 5, the Treaty of Fort Stanwix is signed. The Iroquois Confederacy (a league of six Native American nations also known as the Haudenosaunee) sell the Ohio Valley to the British. None of the Tribes living in the Ohio Valley are consulted.

1774 – Lord Dunmore’s War

Lord Dunmore’s War is started by the Virginian militia, led by Virginia’s last royal governor. It ends on October 10 in the Battle of Point Pleasant. This takes place along the Ohio River in what is now western West Virginia. After furious combat, allied Native American fighters led by Shawnee Chief Cornstalk are forced to retreat.

1775 – American Revolution begins.

Many Tribes in the Ohio Country ally with the British during the American Revolution, hoping to drive out the colonists.

1777 – British plan western diversions.

On March 26, the British War Office instructs Henry Hamilton, lieutenant governor of Detroit, to use Native American allies to make diversionary actions on the frontier without harming inhabitants of the Ohio Country. Their objective is to bring war to the Ohio Valley and ultimately capture Fort Pitt.

1777 – Congress responds.

On November 20, the Continental Congress receives a letter from the Vice-President of the Commonwealth of Pennsylvania. It concerns threats in the west from the British at Detroit that are stirring up unrest through the region. Congress sends representatives to the area to investigate the problems and tries to meet with the Shawnee and Lenape (Delaware) chiefs.

1778 – Fort Laurens is established.

In early December, American troops establish Fort Laurens on the west bank of the Tuscarawas River near Bolivar, Ohio. The fort will be the staging point for an expedition against Fort Detroit, the headquarters for British military operations in the west.

1779 – Fort Laurens is under siege.

From February 22 to March 20, a few British soldiers and 180 Wyandot, Cayuga, Seneca, Munsee, and Lenape (Delaware) warriors lay siege to Fort Laurens. The garrison is reduced to near starvation. The besieging forces also suffer privation. The siege is lifted three days before an American relief expedition arrives from Fort Pitt.

1779 – Fort Laurens is abandoned.

On August 2, the last Continental Army troops leave Fort Laurens. With their departure, colonists in eastern Ohio and western Pennsylvania must rely on local militiamen for defense.

1780 and 1781 – Attacks and reprisals increase.

Violence escalates between colonial militias and Tribes in the Ohio Country. The cycle of attacks and reprisals causes tensions to reach a boiling point.

1782 – Gnadenhutten Massacre

On March 8, militiamen from Pennsylvania kill more than 90 pacifist Christian Lenape at the Moravian mission in Gnadenhutten, Ohio. A third are children. A few escape to rejoin the main group. The Gnadenhutten Massacre unifies a diverse group of Tribes against the American revolutionaries. Several years later, members of this Christian Lenape group overwinter at Pilgerruh in Cuyahoga Valley.

1783 – Treaty of Paris

This treaty officially ends the war between Great Britain and the American colonists. The British cede the Ohio Country to the United States, leaving its Native American occupants in limbo. Considering the Ohio Country as spoils of war, colonists from Pennsylvania and Virginia begin moving into Indian territory.

For years there had been attacks by colonists and native peoples on each other both north and south of the Ohio River. After the war, Governor Arthur St. Clair determines to lead a punitive expedition into the Shawnee and Miami lands. He says this is retaliation for the killings of American settlers and travelers on the contested frontier, and to deter the Tribes from further attacks.

1785 – Treaty of Fort McIntosh

On January 21, the Treaty of Fort McIntosh is signed by the United States and Wyandot, Lenape (Delaware), Chippewa, and Ottawa representatives. The treaty makes the lower Cuyahoga River, the Portage Path, and the Tuscarawas River part of the western boundary of the United States. Other Tribal members dispute the treaty, saying that some signers did not have the authority to do so.

1786 – Connecticut’s Western Reserve

As part of the ratification of the US Constitution, Connecticut cedes most of its lands west of the Appalachian Mountains. These had been granted by its royal charter in 1662. Connecticut retains its Western Reserve, a 120-mile strip in what is now Northeast Ohio. It stretches along the Lake Erie shoreline from Pennsylvania in the east to Sandusky Bay in the west. Western Reserve land west of the lower Cuyahoga River is outside the US boundary set by the controversial Treaty of Fort McIntosh.

1786 – Pilgerruh is established.

Fleeing intolerance and the terror of the Gnadenhutten Massacre, 95 Christian Lenape and six Moravian-German missionaries build a temporary village in Cuyahoga Valley. It is later called Pilgerruh, meaning “Pilgrim’s Rest.” After a harvest, they overwinter and continue on, searching for a safe haven.

1787 – Northwest Ordinance

On July 13, Congress establishes the Old Northwest Territory. It creates a path to statehood for a region northwest of the Ohio River that includes what is now Illinois, Indiana, Michigan, Ohio, Wisconsin, and part of Minnesota. White settlement goes slowly because Native Americans still occupy the area and do not want to leave. The Northwest Ordinance states that tribal lands shall not be taken without consent and never be invaded or disturbed. However, during the following years, the United States signs four treaties to make the process easier for colonists. With each treaty, Native American resentment grows. Colonists repeatedly breach the treaty lines. This fuels a cycle of back-and-forth violence.

1790 – Harmar Expedition

On September 26, US General Josiah Harmar’s army of more than 1400 men departs Fort Washinton in present day Cincinnati, Ohio. It includes militia from Kentucky and Pennsylvania, and 320 regular army soldiers. They begin to march north along the Little Miami and then the Great Miami rivers. The aim is to challenge Native American power on the western frontier. By October 22, Harmar and his men are outmaneuvered by Miami Chief Little Turtle, with militiamen fleeing and high casualties. It becomes known as Harmar’s Defeat.

1791 – St. Clair’s Defeat (Battle of the Wabash)

On November 4, US General Arthur St. Clair leads 1000 US army soldiers against 1000 Miami, Shawnee, Delaware, and Potowatomi warriors led by Little Turtle, Blue Jacket, and Buckongahelas. The Native fighters make a surprise attack at dawn, completely routing St. Clair’s army at what is now Fort Recovery, Ohio. Only 24 soldiers escape unharmed. Note that in both Harmar and St. Clair’s advances, they burn and destroy Native villages and food sources. This leaves Tribes without food or permanent shelter.

1792 – The Firelands

The state of Connecticut grants 500,000 acres of its Western Reserve to 1,870 families whose homes were burned by Great Britain during the American Revolution. Many “fire sufferers” sell their Firelands property to land speculators and never emigrate to this western-most section of the Western Reserve.

1794 – Battle of Fallen Timbers

On August 20, the Battle of Fallen Timbers culminates years of fighting between the US Army and a federation of Shawnee, Miami, Wyandot, and other Native nations. US Major General Anthony Wayne commands a decisive victory near present day Toledo, Ohio. This leads to the Treaty of Greenville.

1795 – Treaty of Greenville

On August 3, following a major defeat in the Battle of Fallen Timbers (1794), 12 Native American nations cede all their lands east of the Cuyahoga River. The Treaty of Greenville creates a temporary, uneasy peace. Connecticut sells most of its Western Reserve property, incorrectly thought to be 3 million acres, to the Connecticut Land Company. The company plans to survey and sell the portion of this land that is east of the Cuyahoga River.

1796 – First Western Reserve survey party

On July 22, Moses Cleaveland arrives at the mouth of the Cuyahoga River. He leads a group of surveyors who begin mapping out land tracts in the newly ceded Western Reserve. By October, the town site of Cleaveland (later spelled Cleveland) is laid out.

1797 – Second Western Reserve survey party

Western Reserve surveyors such as Amzi Atwater continue their work for the Connecticut Land Company. They divide the land east of the Cuyahoga River into five-mile-square townships.

1800 – Western Reserve settlement begins slowly.

Settlement by New Englanders in the Western Reserve proceeds slowly. There are only 1000 people living east of the Cuyahoga River, and only three men living in Cleveland itself. The lack of safe and reliable transportation plus “Indian worries” deters settlers.

1803 – Ohio becomes a state.

On March 1, Ohio is admitted to the union as the 17th state of the United States. It was formed from part of the Old Northwest Territory. During this period, most Native Americans have been displaced from their homelands. Some live in towns with refugees from different nations. Some move west to Indiana, Missouri, and Kansas seeking peace and safety. Some rally around strong leaders to resist.

1805 – Treat of Fort Industry

On July 4, in the Treaty of Fort Industry, Tribes cede all lands in the Western Reserve to white settlers. David Hudson, George Darrow, William Walker, and Joshua Stow are among those who settled here earlier under the Treaty of Greenville.

1805 – Rise of Tenskwatawa

Tenskwatawa, also known as “The Prophet,” is brother to Tecumseh, the Shawnee War Chief who is unifying Indian political and military power. Tenskwatawa has a vision that asks for the Shawnee to give up liquor and return to traditional ways. Many Lenape (Delaware) and Wyandot join this movement.

1806 – Early Western Reserve settlers in Cuyahoga Valley

James Stanford, Alfred Wolcott, and Samuel Ewart have settled in what would become Boston Township in the heart of Ohio’s Cuyahoga Valley. Early settlers tell of an Ottawa (Odawa) village north of Boston.

1810 – Jonathan Hale arrives in Cuyahoga Valley

Jonathan Hale settles in what is now Bath, Ohio. His family encounters Seneca and Cayugas from a village near his land.

1812 – War of 1812 begins.

The War of 1812 between America and the United Kingdom of Great Britain and Ireland begins.

1813 – Key battles in the region

On January 18 and January 22, the first and second Battle at the River Raisin (also called the Battle of Frenchtown) are fought between American and allied British and Native American forces. This occurs in Michigan territory, south of Detroit. The battles culminate in a surprise counterattack that routes American forces. Many American prisoners, including some wounded, are killed in the following days. This is in retaliation for the treatment of Native Americans. Following this, American troops rally around the cry to “Remember the Raisin!”

On September 10, the US Navy defeats the more powerful British Royal Navy in the Battle of Lake Erie. The victory, led by Master Commandant Oliver Hazard Perry, allows the United States to control Lake Erie.

On October 5, the decisive Battle of the Thames (also known as the Battle of Moraviantown) is fought near Thamesville, Ontario. The US military defeats the American Indian Confederacy and their allies, the British. Shawnee leader Tecumseh is killed. This breaks the back of unified Tribal resistance, although small skirmishes continue throughout the Old Northwest Territory until the War of 1812 ends. Following the battle, the US Army burns the Moravian Delaware community of Fairfield. New Fairfield, later called Moraviantown, is rebuilt south of the river over the following two years.

1815 – War of 1812 ends.

The War of 1812 finishes in a stalemate. The Treaty of Ghent is signed on December 24, 1814, and fully ratified in February 1815. The remaining Native Americans, whose populations are scattered and diminished, have their lands overtaken by European Americans. Food is scarce as most game has been hunted out.

1817 – Treaty of Fort Meigs

On September 29, the US signs this treaty with representatives of Wyandot, Seneca, Lenape (Delaware), Shawnee, Potawatomi, Ottawa (Odawa), and Chippewa (Ojibwe). These Tribes cede their claims to 4.6 million acres in northwestern Ohio, northeastern Indiana, and southern Michigan. The treaty sets up Ohio reservations for the Wyandot in Upper Sandusky, for the Seneca along the Sandusky River, and for the Shawnee in three locations.

1830 – Indian Removal Act

On May 28, President Andrew Jackson signs the Indian Removal Act. This allows the President to grant lands west of the Mississippi in exchange for Indian lands within existing state borders. Jackson appoints Lewis Cass as Secretary of War to implement the Indian Removal Act and James B. Gardiner to negotiate with tribes in Ohio. A few Tribes go peacefully. Many resist relocation.

1832 – Shawnee and Seneca leave Ohio.

The US forces the Shawnee to leave their Ohio reservations and march to Kansas. The Mixed Band from Lewiston are joined by the Seneca who have been living with them. Journals kept by the men overseeing the removals document the hardships. When the Mixed Band arrives on December 18, they learn that the tract they were given is actually owned by the Cherokee who object to their settlement.

1839 – Ottawa leave Ohio.

During the 1830s, the US removes 349 Ottawa (Odawa) from Ohio to Kansas in three trips. Au-to-kee, a grandson of Pontiac, leads the last journey from July 25 to August 30, 1839, with 107 people. Their route by boat takes them through the Cuyahoga Valley via the Ohio & Erie Canal. Within a few years, about half of the roughly 500 Ottawa from Ohio die of illness, malnutrition, and exposure in Kansas.

1843 – Indian removal finishes in Ohio.

Starting on July 11, the US removes the last Tribe in Ohio, the Wyandot, from Upper Sandusky and resettles them in Kansas. Their arduous journey is made on foot with their goods in wagons and then by steamboat. Later, the tribe splits. Some Wyandot stay in Kansas and others move to Oklahoma, becoming the Wyandotte Nation.
