Lewis and Clark are two names that almost every American and many people across the world know, who are known for their historic expedition across the continental US. However, the expedition the Corps of Discovery set out on most likely would not have been possible without one man: William Clark’s big brother, George Rogers Clark.
Into the Wilderness
It’s 1779, and 130 men set off through freezing rain and flooded plains. For over two weeks, they slogged through waist-deep water, broke ice to make camp, and went days without food. The land turned against them, endless bogs, swollen creeks, and prairie rivers that had swallowed their banks. Clark waded alongside them, never asking a man to go where he wouldn’t. The rivers were swollen and black. The wind ripped through the trees like musket shot. And out of the flooded Illinois wilderness marched a gaunt, half-frozen column of men, faces hollow, clothes ragged, rifles held above their heads to keep them dry. Their target is Fort Sackville at Vincennes, Indiana (present-day Vincennes). At the front of this month’s crew strode the man who had led the fighting on the frontier since 1777. He was a tall, sharp-eyed Virginian with a hunter’s gait and a commanding presence.
A Frontiersman then a Gentleman
George Rogers Clark wasn’t a polished general like many of his fellow Virginia officers fighting in the east, under Washington. He was a frontiersman, molded by the raw country and years on the frontier. Born in Virginia in 1752, Clark had traded civilization for Kentucky, which at the time was the frontier. Kentucky, Ohio, Illinois, and the surrounding states at the time were characterized by vast forests, rich resources, and the presence of native tribes. In these immense forests and river valleys, he learned how to track, endure brutal conditions, and lead men. Those expenses and his insight into the frontier helped him see its vast potential. By the time the Revolution broke out, he understood something most in Congress didn’t: if America wanted to be more than a narrow strip of coast, it would have to win the West.
The British Grip on the Old Northwest
The British and their Native allies safely held the Old Northwest, from strongholds like Detroit, Kaskaskia, and Vincennes. They sent war parties to burn American cabins and cut down settlers. Due to the Continental Army being tied to the northern colonies to fight the main force of the British army, there really was no one to send West to counter this British presence. And so, Clark proposed to the Governor of Virginia, Patrick Henry, that we would march into the Old Northwest with a militia made up of Virginians and other frontiersmen to strike the British where they least expected, and take the West for Virginia and the cause of liberty.
Lightning Raids and Winning Allies
In 1778, with somewhere between 120 and 175 men and a few flatboats, Clark drifted down the Ohio River. His targets were the outposts of Kaskaskia and Cahokia, French towns loyal to the British through fear, not love. Clark landed under the cover of night, stormed Kaskaskia without a shot, and stunned the locals with bold diplomacy instead of bloodshed. He won them over not by the sword, but by convincing them that the American cause would bring freedom, not more war. It worked. French militias joined his cause, and word of his success spread like wildfire.
A Brutal Winter and a Daring Plan
However, Clark’s most legendary feat occurred the following winter.
Vincennes, a strategic fort on the Wabash River, had fallen back into British hands under the cold grip of Governor Henry Hamilton, a man Americans called the “Hair Buyer” for paying bounties on settler scalps. Clark learned that Hamilton had sent most of his force north for the winter. It was a window. A dangerous one. But it might be the only chance he’d get to take the Fort and to capture or kill Hamilton.
The Ghosts from the Swamps
Now, back to where our story began. With Clark leading from the front, they trudged through the swamps. His men wrapped wet powder in deerskin to keep it dry. They roasted bits of leather and bark to stay alive. At one crossing, the water came up to their necks. Clark ordered a drummer boy to play a march to keep morale from drowning in the mud. And then, like ghosts rising from the mist, they arrived at Vincennes.
A Mad Man with a Mad Plan
Hamilton never saw them coming. Clark ringed the town and opened fire with what few muskets and cannons he had. He ordered constant volleys, his men moved from place to place, making it seem as though an army surrounded the Fort. The goal was also to keep the Brits on their feet and start to deprive them of sleep.
Then his men captured several Native scouts allied to the British. In full view of the Fort’s defenders, Clark ordered them executed swiftly and brutally. Using the tactics the natives had employed on the frontier during his years, he sent a message. Clark was no longer asking for surrender. He was demanding it anyway; if they would not surrender, he would kill every single one of them. Hamilton was shocked by the sudden attack, unnerved by the “Hannibal of the West” as Clark would become known ruthlessness. Lacking the numbers to fight, Fort Sackville surrendered on February 25. Without reinforcements. Without supplies. Without winter gear. Clark had just pulled off one of the most daring victories of the entire war.
Securing the American West
His brutality was not arbitrary; it was calculated and deliberate. In the unforgiving wilderness, where mercy could mean the death of villages, families, and entire settlements, Clark fought a war as merciless as the one waged against him. His tactics were scorched-earth, win over who you can, crush the rest with speed, terror, and resolve. Those tactics would keep the Redcoats from ever really securing the frontier for the remainder of the war. When the war ended and the 1783 Treaty of Paris was signed, it compelled the British to acknowledge the claims of the young nation and cede all the land west of the Appalachians to the Mississippi River. None of this would have been possible without Clark taking charge in the West and leading the fight. Without him, there might never have been a Lewis and Clark Expedition, and America might look much smaller.
