Price's Missouri Expedition, also known as Price's Raid, is a Confederate raid through the states of Missouri and Kansas in the Trans-Mississippi Theater of the American Civil War during the autumn of 1864.
Led by Confederate Major General Sterling Price, the campaign's intention is to recapture Missouri and renew the Confederate initiative in the larger conflict.
Despite winning several early victories, Price is ultimately defeated at the Battle of Westport by Union forces under Maj. Gen. Samuel R. Curtis in late October.
He suffers subsequent reverses at the hands of Union cavalry under Maj. Gen. Alfred Pleasonton at the Battle of Mine Creek, Kansas, forcing him to retreat back into Arkansas
Price's Raid proves to be the last significant Southern operation west of the Mississippi River.
Its failure bolsters confidence in an ultimate Union victory in the war, thereby contributing to President Abraham Lincoln's re-election
It also cements Federal control over the hotly-contested border state of Missouri.
