The Yazoo Pass expedition was a joint operation of Major General Ulysses S. Grant's Army of the Tennessee and Rear Admiral David D. Porter's Mississippi River Squadron in the Vicksburg campaign of the American Civil War. Grant's objective was to get his troops into a flanking position against the Rebel defenders. The expedition was an effort to bypass the Confederate defenses on the bluffs near the city by using the backwaters of the Mississippi Delta as a route from the Mississippi River to the Yazoo River. Once on the Yazoo, the Army would be able to cross the river unopposed and thus achieve their goal. The operation would require a deep penetration into enemy territory that was dominated by water, so cooperation between the two services was necessary. The Army was led by Brigadier General Leonard F. Ross. Naval commander was Lieutenant Commander Watson Smith, who was in extremely poor health; his health was an important factor in the ultimate failure of the expedition.

In February and March 1863, she was part of the Yazoo Pass Expedition, and she fought with Confederates at river landings later in the year to help isolate Vicksburg, Mississippi, during the Vicksburg campaign.
