Lieutenant Colonel [[George Rogers Clark|George R. Clark]], Captain Leonard Helm, and others created a plan to capture the French forts that the British occupied after Louisiana was ceded. After Kaskaskia was captured by Clark, Lieutenant Governor [[Henry Hamilton (governor)|Henry Hamilton]] sent British soldiers and reinforcements from Detroit to Fort Vincennes and helped to rebuild the fort.{{citation needed|date=November 2020}}

The [[Italians|Italian]] merchant and Patriot [[Francis Vigo]] found Clark and informed the British presence at the fort. Vigo served with the Patriots, ordered war supplies from the Spanish to help, and acted as a secret agent for the Patriots. Clark rounded up enough men to outnumber the British and planned a surprise attack on Fort Vincennes in the heart of winter, a horrible time when no armies were expected to be able to attack due to illness, lack of food, and the flood waters that were high during this time. The Patriots won the Battle of Vincennes on February 23–24, 1779. Hamilton thought of Vincennes as "a refuge for debtors and Vagabonds from Canada." [[George Rogers Clark]] recaptured Fort Sackville in the [[Battle of Vincennes]] without losing a single soldier.{{citation needed|date=November 2020}}
