Atzerott had a room almost directly over Vice-President Johnson's. He had all the materials to do murder, but lost spirit or opportunity. He ran away so hastily that all his arms and baggage were discovered; a tremendous bowie-knife and a Colt's cavalry revolver were found between the mattresses of his bed. Booth's coat was also found there, showing conspired flight in company, and in it three boxes of cartridges, a map of Maryland, gauntlet for riding, a spur and a handkerchief marked with the name of Booth's mother--a mother's souvenir for a murderer's pocket! Atzerott fled alone, and was found at the house of his uncle in Montgomery county. I do not know that any instrument of murder has ever made me thrill as when I drew this terrible bowie-knife from its sheath. Major O'Bierne, of New-York, was the instigator of Atzerott's discovery and arrest. I come now to the ride out of the city by the chief assassin and his dupe. Harold met Booth immediately after the crime in the next street, and they rode at a gallop past the Patent Office and over Capitol Hill. As they crossed the Eastern branch at Uniontown, Booth gave his proper name to the officer at the bridge. This, which would seem to have been foolish, was, in reality, very shrewd. The officers believed that one of Booth's accomplices had given this name in order to put them out of the real Booth's track. So they made efforts elsewhere, and so Booth got a start. At midnight, precisely, the two horsemen stopped at Surrattsville, Booth remaining on his nag while Harold descended and knocked lustily at the door. Lloyd, the landlord, came down at once, when Harold pushed past him into the bar, and obtained a bottle of whiskey, some of which he gave to Booth immediately. While Booth was drinking, Harold went up stairs and brought down one of the carbines. Lloyd started to get the other, but Harold said: "We don't want it; Booth has broken his leg and can't carry it." So the second carbine remained in the hall, where the officers afterward found it. As the two horsemen started to go off, Booth cried out to Lloyd: "Do you want to hear some news?" "I don't care much about it," cried Lloyd, by his own account. "We have murdered," said Booth, "the President and Secretary of State!" And with this horrible confession, Booth and Harold dashed away in the midnight, across Prince George's county.
