Booth fled into Maryland after shooting Lincoln and rendezvoused with Herold. Lincoln's Secretary of War, Edwin Stanton, directed the largest manhunt in US history at the time, involving thousands of troops. After a 12-day search, on April 26, Booth and Herold were located at a tobacco farm in King George County, Virginia; Booth was fatally shot by Sergeant Boston Corbett after refusing to surrender. The other conspirators were captured by the end of April 1865, except for John Surratt, who the US captured in Egypt in November 1866. Powell, Herold, Atzerodt, and Mary Surratt were hanged in July 1865, while John Surratt was released after a mistrial in 1867 and never retried.
