Fort Kaskaskia State Historic Site

Fort Kaskaskia State Historic Site is a 200-acre (0.8 km²) park near Chester, Illinois on a blufftop overlooking the Mississippi River. It commemorates the vanished frontier town of Old Kaskaskia and the support it gave to George Rogers Clark in the American Revolution.

An earthen redoubt

The village of Kaskaskia, Illinois was founded at the mouth of the Kaskaskia River as a missionary post by the Jesuits in 1703. Soon afterwards, settlers from the Quebec and Louisiana regions began to trickle towards the rich, alluvial farmland of the central Mississippi Valley. They built a village and agricultural settlement around the location of the Jesuit mission, a half-circle of bottomland cradled by the Kaskaskia River and by an oxbow of the Mississippi.

French-speaking pioneers were noted throughout North America for their comparative fairness towards Native Americans. However, as the Kaskaskia settlement grew throughout the 1700s, the local Indians, members of the Illini Confederacy may have realized that there might not be enough space for everybody. At some point Fort Kaskaskia was raised atop the bluff that looked down upon the frontier village. "Fort Kaskaskia" is not technically a "fort", but an earthen redoubt. Frontier settlers throughout Woodland North America often built such redoubts as defensive moves during times of threat from Native Americans. The Illinois Historic Preservation Agency, which operates Fort Kaskaskia State Historic Site, does not know when the redoubt was raised, but suggests the date was "sometime during the mid-1700s." ^*

In 1763 the French ceded the Illinois country, including Kaskaskia and the redoubt, to Great Britain. The British did not use the redoubt and left Kaskaskia almost defenseless. Kaskaskia continued to exist as a French-speaking village on the Mississippi River frontier.

A key strategic location

In early 1778, George Rogers Clark, eager to defend western Virginia and the Kentucky country from attacks by Native Americans allied to the British, led a tiny force down the Ohio River. Clark hoped to achieve a strategic coup by linking his expeditionary column with the French-speaking settlements of the Mississippi Valley.

Clark and his men marched overland from Fort Massac, near the present-day Metropolis, Illinois, to Kaskaskia. They avoided being sighted by the British or their Native allies and arrived at Kaskaskia on July 4, 1778. Most of the Kaskaskia townspeople welcomed them.

After facing a threat from a British force at Vincennes, Indiana, Clark and his men used Kaskaskia as their jumping-off place to capture Vincennes in early 1779. The Americans controlled Kaskaskia and its redoubt throughout the rest of the war, and won legal control of the territory in the 1783 Treaty of Paris.

Kaskaskia, Illinois

Following the war, Kaskaskia was part of the United States and became slowly Americanized. Lewis and Clark stopped here in 1803 and recruited many of the professional hunters and sharpshooters that accompanied them to the Pacific Ocean in their fateful 1804-06 expedition.

The village served as the only capital of Illinois Territory in 1809-1818, and briefly (1818-1820) as the first capital of the new U.S. state of Illinois following Illinois's admission to the Union on December 3, 1818. Pierre Menard, a wealthy fur trader who lived across the Kaskaskia River from Kaskaskia at the bottom of the Fort Kaskaskia redoubt, was elected the new state's first Lieutenant Governor.

Disaster and new life

During much of the 1800s and especially after the American Civil War, the Mississippi River cut through many of its former oxbows and shortened its channel considerably.

In 1881, during a flood, the moving water of the Mississippi "discovered" a much smaller, parallel riverbed, the mouth of the Kaskaskia. Kaskaskia's bed was a few feet lower than the Mississippi's bed, so the whole river shifted to the new watercourse, cutting across the head of a former oxbow to do so.

For the village of Kaskaskia, the river's new course was disastrous. Their village had been by the waterfront of the much smaller river; now the mighty Mississippi was swallowing the town up. Even the village cemeteries were at risk.

In an emergency operation, 3,000 graves of the departed of Kaskaskia were exhumed and the remains reburied atop the bluff to the east, at the site of old Fort Kaskaskia. The state of Illinois agreed to maintain the site forever as a memorial to the vanished historic village.

The fort today

Fort Kaskaskia is a campsite and picnic area overlooking the Mississippi River. The remains of the 18th-century redoubt can be vaguely traced in the earth. The prominent Kaskaskia cemetery recalls the 1881 flood.
