September 13, 1861
- The siege of Lexington, also known as the Battle of First Lexington, was a minor conflict of the American Civil War. The siege took place from September 13 to 20, 1861 between the Union Army and the pro-Confederate Missouri State Guard in Lexington, county seat of Lafayette County, Missouri. The victory won by the Missouri Guard bolstered the considerable Southern sentiment in the area, and briefly consolidated Missouri State Guard control of the Missouri River Valley in the western part of the state. Confederate Sterling Price, with 18,000 men, faced a federal force of 3.600 under Colonel James Mulligan. After fighting intensified on September 19, Mulligan surrendered on the 20th.
- Entering Confederate-controlled Pensacola harbor, Lt. John Henry Russell destroys the privateer Judah, marking the first naval action of the Civil War.
