The Battle of Yazoo City (March 5, 1864) was an engagement in Mississippi during a month-long Union expedition up the Yazoo River in the American Civil War. The Union force commanded by Colonel James Henry Coates repulsed an attack led by Confederate Brigadier General Lawrence Sullivan Ross. The Union force suffered greater losses and withdrew down the river the next day with a large amount of cotton seized or bought from plantations along the river. The expedition was undertaken in cooperation with Major General William Tecumseh Sherman's Meridian campaign.
