Where was Vincennes during the Revolutionary War?

During the Revolutionary War, Vincennes was a strategic frontier settlement located in the Illinois Country, which was part of the British-controlled territory. It became significant when American forces captured it in 1779 during the Illinois Campaign, led by General George Rogers Clark. This victory helped secure the Northwest Territory for the United States and weakened British influence in the region. Vincennes' location along the Wabash River made it an important point for trade and military operations during the conflict.
