Steele's Greenville expedition

Steele's Greenville expedition took place from April 2 to 25, 1863, during the Vicksburg campaign of the American Civil War. Union forces commanded by Major General Frederick Steele occupied Greenville, Mississippi, and operated in the surrounding area, to divert Confederate attention from a more important movement made in Louisiana by Major General John A. McClernand's corps.
