The Early Republic at War

The wars of the young republic, 1784 to 1845

The half-century between the end of the Revolution and the eve of the Mexican War was not a time of peace for the young United States. Its wars fell into two broad kinds. The first was a second contest with Britain, the War of 1812, fought across the Great Lakes and the Niagara frontier, along the Chesapeake and the coast of Maine, and on the Gulf at New Orleans. The second was a long series of frontier wars with the Native nations whose land the republic was expanding onto: the Northwest Indian War for the Ohio Country, the Creek War in the Old Southwest, the Seminole Wars in Florida, and the Black Hawk War on the upper Mississippi. The engagements gathered here are drawn from the federal battlefield survey and the documented historical record, each tied to a named place and, where the record allows, a date and an outcome.

War of 1812

The War of 1812 was fought between the United States and Britain from 1812 to 1815. Its causes lay in British interference with American trade and shipping during the Napoleonic Wars, the impressment of American sailors, and rising tension on the western frontier. When war came neither side was ready, and the fighting spread across the Great Lakes and the Canadian border, the Atlantic coast, the Chesapeake, and the Gulf. It ended with the Treaty of Ghent and a return to the pre-war boundaries. The course of the fighting is set out below.

Creek War

The Creek War was fought in 1813 and 1814 in the Old Southwest, chiefly across what is now Alabama. It began as a civil conflict within the Creek Nation, between the traditionalist Red Sticks and the Creeks allied with the United States, and widened into war with American militia and volunteers after the Red Stick attack on Fort Mims in August 1813. Through the autumn and winter, American columns under commanders including Andrew Jackson struck the Red Stick towns at Tallushatchee, Talladega and the Holy Ground, and the war was decided in March 1814 at Horseshoe Bend on the Tallapoosa. The settlement that followed is set out below.

Seminole Wars

Between roughly 1816 and 1858, three separate but related conflicts pitted the United States against the Seminoles across Florida, together known as the Seminole Wars or the Florida Wars. Rather than treating them as distinct episodes, the Seminole Tribe of Florida regards this history as a single continuous struggle, since periods without direct fighting against the Army still brought violence from settlers, militias, lawmen, and slavecatchers targeting the Seminole people.

The Seminole nation itself formed in northern Florida in the early eighteenth century, back when Spain still held the territory as a colony. As American settlement expanded following independence, friction developed in the early 1800s between these settlers and the Seminoles, largely because enslaved people kept escaping across the border from Georgia into Spanish-held Florida, which led slaveowners to launch raids into Spanish territory to reclaim them. These border skirmishes escalated into the First Seminole War when Andrew Jackson brought American troops into Florida, ignoring Spanish protests, in order to hunt down the Seminoles. His campaign leveled multiple Seminole, Mikasuki, and Black Seminole settlements, seized San Marcos de Apalache, and led to a temporary occupation of Pensacola before Jackson pulled his forces out in 1818. The following year, Spain and the United States settled Florida's fate through the Adams-Onís Treaty.

Florida formally passed to American control in 1821, after which the Seminoles were pressured through the Treaty of Moultrie Creek into abandoning the panhandle for a sprawling reservation carved out in the peninsula's interior. This arrangement did not last: the Treaty of Payne's Landing in 1832, pushed by President Andrew Jackson's administration, insisted the Seminoles abandon Florida entirely in favor of Indian Territory, present-day Oklahoma, under the terms of the 1830 Indian Removal Act. Those Seminoles who rejected removal fought back, sparking the Second Seminole War, which lasted from 1835 to 1842 and proved far longer and more extensive than either of the other two conflicts. At the outset, a Seminole fighting force numbering under 2,000 relied on guerilla tactics and superior familiarity with the terrain to outmaneuver and wear down an American military and Marine presence that eventually swelled past 30,000 troops. Rather than continuing to chase these elusive bands, U.S. commanders shifted tactics, concentrating instead on locating and destroying concealed Seminole villages and food supplies, a strategy meant to force resisters into surrender through hunger or watch their families suffer the consequences.

By 1842, some 3,612 Seminoles had been forced into Indian Territory, though a small remnant, somewhere between 350 and 500 people, stayed behind in Florida under a fragile and uneasy peace. That calm broke down once again when the Armed Occupation Act of 1842 opened land south of Tampa to new settlement, provoking fresh conflict that ignited the Third Seminole War in 1855. When active combat finally ceased in 1858, the handful of Seminole bands still remaining in Florida had retreated deep into the Everglades, into swampland that held no appeal for American settlers.

Taken together, these conflicts stand as both the lengthiest and the costliest of all the American Indian Wars.

Black Hawk War

The Black Hawk War pitted the United States against Native Americans under Black Hawk, a Sauk leader, in a conflict rooted in disputed land claims. Fighting began when Black Hawk led a mixed group of Sauks, Meskwakis (Fox), and Kickapoos, called the "British Band," across the Mississippi from Iowa Indian Territory into Illinois during April 1832. Historians remain uncertain of his exact intentions, though he seems to have wanted to recover territory the United States had absorbed through the contested Treaty of St. Louis in 1804.

Believing the British Band posed a genuine threat, American officials called up frontier militia forces, who fired on a Native American delegation on May 14, 1832. Black Hawk retaliated with a decisive strike against the militia at Stillman's Run. Afterward he withdrew his followers to a defensible position in what is today southern Wisconsin, drawing U.S. troops in pursuit. With the militia occupied elsewhere, other Native groups launched raids on poorly defended forts and settlements. Some warriors from the Ho-Chunk and Potawatomi joined these attacks, though most members of those tribes stayed out of the fighting. The Menominee and Dakota, already rivals of the Sauks and Meskwakis, sided with the Americans.

General Henry Atkinson directed the American pursuit of the British Band. On July 21, Colonel Henry Dodge's militia overtook the group and won the Battle of Wisconsin Heights. Starvation, mounting deaths, and desertions had by then depleted Black Hawk's forces, pushing many surviving Native Americans back toward the Mississippi. When U.S. troops caught up with what remained of the British Band on August 2, they struck at the Battle of Bad Axe, killing large numbers and taking most of the survivors prisoner. Though Black Hawk and several other leaders managed to flee, they eventually gave themselves up and spent a year in confinement.

Among the war's lasting footnotes is Abraham Lincoln's brief stint in uniform, though he never engaged in battle. Others who fought and later gained wider recognition include Winfield Scott, Zachary Taylor, Jefferson Davis, and James Clyman. The conflict subsequently served as justification for the government's Indian removal policy, under which Native American nations were compelled to cede their lands and relocate west of the Mississippi River.

Northwest Indian War

Control over the Northwest Territory sparked a prolonged military struggle between the United States and an alliance of Native American peoples who identified themselves as the United Indian Nations, a group now more commonly recognized as the Northwestern Confederacy. Within the annals kept by the United States Army, this clash stands as the earliest of what would become known as the American Indian Wars.

The territory in question had long been contested ground, with Native Americans and European powers vying for dominance there over many generations. That struggle shifted decisively when Great Britain handed over the lands of the Northwest Territory to the newly established United States through the Treaty of Paris in 1783. This agreement set the Great Lakes as the dividing line separating British North America from American soil, granting the United States authority over the Ohio Country and Illinois Country, regions that had previously been closed off to European settlers. Once American settlers began pushing into this territory, they encountered fierce opposition from the Native peoples already living there. In response, a confederacy led by the Wyandot took shape in 1785, aiming to push back against the American advance onto their homelands.

The confederacy had existed for four years when the newly ratified Constitution took effect, bringing George Washington into office as president and, with that role, command over every branch of American military power. Washington then instructed the Army to assert American authority throughout the Northwest Territory. Composed largely of inexperienced soldiers supplemented by militia volunteers, the Army suffered repeated humiliating losses during this effort, among them the failed Harmar campaign of 1790 and the catastrophe known as St. Clair's defeat the following year, both of which rank among the most severe setbacks the Army has ever endured.

The devastation at St. Clair's defeat left the bulk of the Army in ruins and exposed frontier settlers to further danger. In response, Washington turned to General Anthony Wayne to rebuild the shattered force. Wayne restructured the Army into what became known as the Legion of the United States in 1792, devoting an entire year to training the men and ensuring they were properly equipped. From there, he guided a deliberate, carefully planned advance through the Great Miami and Maumee river valleys within the Ohio Country, culminating in a crushing triumph at the Battle of Fallen Timbers near Lake Erie in 1794. Following this victory, Wayne established Fort Wayne at Kekionga, the Miami capital, and the beaten confederacy found itself compelled to surrender vast stretches of land, including much of what is now Ohio, under the terms of the Treaty of Greenville signed in 1795. This conflict secured American dominance over the Northwest Territory for a time, though British troops would return to invade the region during the War of 1812.
