The Battle of Cape Girardeau was a military demonstration of the American Civil War, occurring on April 26, 1863 in Cape Girardeau, Missouri. The conflict was part of the pursuit of US Brigadier General John McNeil through Southeast Missouri by Confederate Brigadier General John S. Marmaduke. Though the conflict to this day is known as a battle, it was a relatively small engagement whose primary importance was as the turning point that brought General Marmaduke's second Missouri raid to an end.
