In reference to the search for Lincoln's killers as it took to the Maryland swamps: "The method of searching the swamps is simple yet arduous. First, the troops assemble on the edge of bogs with names like Allen’s Creek, Scrub Swamp, and Atchall’s Swamp, standing at loose attention in the shade of a thick forest of beech, dogwood, and gum trees. Then they form two lines and march straight forward, from one side to the other.

Incredibly, eighty-seven of these brave men will drown in their painstaking weeklong search for the killers.
