9. The Battle of St. Louis
The Battle of St. Louis, fought on May 26, 1780, stands as the sole battle of the American Revolutionary War to occur west of the Mississippi River. Positioned in the strategic location of St. Louis, this engagement saw Spanish colonial forces and local militia defending against British-led Native American and Loyalist attackers.
Despite being outnumbered, the defenders, led by Spanish Lieutenant Governor Fernando de Leyba, successfully fortified the city with an earthen wall, repelling the assault and preserving St. Louis from British control. This victory not only secured Spanish territorial claims but also demonstrated international support for the American cause, highlighting St. Louis’s importance in the broader geopolitical landscape of the time.
