American Civil War: The Confederates were routed in the Battle of Raymond, a small battle that had an inordinately large impact on the Vicksburg campaign.

The American Civil War was a civil war in the United States between the Union and the Confederacy, which was formed in 1861 by states that had seceded from the Union to preserve slavery in the United States, which they saw as threatened because of the election of Abraham Lincoln and the growing abolitionist movement in the North. The war lasted a little over four years, ending with Union victory, the dissolution of the Confederacy and the abolition of slavery.
