U. S. President James Polk requests 2 million dollars to purchase land from Mexico following the Mexican-American War. David Wilmot of Pennsylvania attaches the "Wilmot Proviso" to this bill. It passes in the House but is tabled in the Senate.
General John McClernand [US] defeats Brigadier General T. J. Churchill [CS] at Fort Hindman or Arkansas Post. Defending the outpost on the Arkansas River, 5,000 Confederates are surrounded by a force of 50,000 Union troops, and a U. S. Naval squadron under the command of Admiral David Porter. The Navy silenced the Confederate artillery and McClernand attacked, gaining the outer walls. The Confederates then surrendered.
Political general John McClernand served as a Democratic Representative from Illinois from 1843 until 1850 and again from 1859 until 1862. He was well acquainted with Abraham Lincoln. He was one of only three northern representatives to vote against the original Wilmot Proviso.
