About four o'clock on the morning following the Lincoln assassination two men on horseback arrived at the Mudd farm near Bryantown. The men, it turned out, were John Wilkes Booth--in severe pain with a badly fractured leg that he received from his fall to the stage after shooting the President--and David Herold. Mudd welcomed the men into his house, first placing Booth on his sofa, then later carrying him upstairs to a bed where he dressed the limb.
After daybreak, Mudd made arrangements with a nearby carpenter to construct a pair of crutches for Booth and tried, unsuccessfully, to secure a carriage for his two visitors. Booth (after having shaved off his moustache in Mudd's home) and Herold left later on the fifteenth, after Mudd pointed the route to their next destination, Parson Wilmer's.
When a military investigator tracking Booth's escape route, Lt. Alexander Lovett, reached Mudd's home on April 18, Mudd claimed that the man whose leg he fixed "was a stranger to him."
Lovett returned to the Mudd home three days later to conduct a search of Mudd's home. When Lovett told of his intentions, Mudd's wife, Sarah, brought down from upstairs a boot that had been cut off the visitor's leg three days earlier [see above photo]. Lovett turned down the top of the left-foot riding boot and "saw the name J Wilkes written in it." Mudd told Lovett that he had not noticed the writing. Shown a photo of Booth, Mudd still claimed not to recognize him.
