In 1864, General Sterling Price with an army of 12,000 ragtag Confederates invaded Missouri in an effort to wrest it from the United States Army's Department of Missouri. Price hoped his campaign would sway the 1864 presidential election, convincing war-weary Northern voters to cast their ballots for a peace candidate rather than Abraham Lincoln. It was the South's last invasion of Northern territory.

But it was simply too late in the war for the South to achieve such an outcome, and Price grossly mismanaged the campaign, guaranteeing the defeat of his force and of the Confederate States. This book chronicles the Confederacy's desperate, final, ill-fated attempt to win a decisive victory.
