The Town the River Took

There is a place in southern Illinois where the Mississippi River changed its mind.

For 178 years, the Kaskaskia River flowed parallel to the Mississippi for several miles before joining it, and between them lay an island of rich bottomland where the French built their most important Illinois settlement in 1703. The town grew. By the 1770s it had 500 residents, a substantial church with a bell presented by King Louis XV, a British fort, and a network of merchants, priests, and farmers who formed the social fabric of the entire Illinois Country. George Rogers Clark captured it on the night of July 4, 1778. In 1818, it became the first capital of the state of Illinois. The Kaskaskia Bell rang for Clark's victory and rang again for statehood.

Then the river decided otherwise. In the spring floods of 1881, the Mississippi carved a new channel directly through the neck of land between the two rivers. Overnight — almost literally overnight — the Kaskaskia River became a backwater and the Mississippi claimed the island. Subsequent floods eroded the bank. The town site slipped into the water. The church where Father Gibault had preached, the fort where Rocheblave was captured, the streets where Clark had assembled the French Creole residents and offered them a choice — all of it went into the river.

What remains is very little. The Kaskaskia Bell survived because someone had the foresight to remove it. It sits now in a small brick chapel on what is left of Kaskaskia Island, accessible by a bridge from Missouri when the water is low enough. The island is technically part of Illinois — the only piece of Illinois west of the Mississippi — but it is difficult to reach, largely uninhabited, and subject to flooding whenever the river rises. You can stand on it and know you are standing where Clark stood on the morning of July 5, 1778. You cannot see much else that connects to that moment.

The Pierre Menard Home survives a few miles away, a beautiful example of French Creole architecture from the early 19th century, its long gallery overlooking the river bottom. Fort de Chartres, the old French stone fort from the 1750s, has been partially reconstructed a few miles north. These are fragments. The center — the town itself, the island, the confluence where two rivers met and a colonial capital stood — is gone.

There is something instructive about this loss. Most of the Revolutionary War sites that shaped the country's founding have been preserved, commemorated, sometimes over-commemorated. Valley Forge has a memorial arch. Yorktown has a battlefield park. Even sites where relatively little happened have markers, plaques, visitors' centers. Kaskaskia, where Clark won an area that became six states, where American sovereignty over the Northwest Territory was first established, where the French Creoles of the Illinois Country made a choice that shaped the entire American midwest — Kaskaskia is underwater.

The historical amnesia is partly geographic. Kaskaskia sits in a corner of southern Illinois that most Americans never visit, far from interstates and population centers. The relevant interpretive site — the George Rogers Clark National Historical Park — is in Vincennes, Indiana, which emphasizes the final dramatic episode (the winter march, Hamilton's capture) over the initial capture of Kaskaskia. The story of July 4, 1778 is not unknown, but it is not well known.

It deserves to be better known. The capture of Kaskaskia was not a great battle — it was a bloodless night operation, an act of intelligence and discipline and surprise. The securing of the Illinois Country was not won by overwhelming force but by cultural intelligence, by Clark's understanding that the French Creole population could be won over rather than subdued. The Northwest Territory was not conquered; it was argued for, diplomatically and militarily, by a 26-year-old Virginian with 175 men and a theory about what the people of Kaskaskia actually wanted.

That theory turned out to be correct. The bell rang. The river took the town. But the consequence — six states, the framework for American expansion across the continent, the legal basis for the Northwest Ordinance — that remains. The town is gone. What the town made possible is all around us.
