Acquittal! Life among the Papal Zouaves in Rome!/A Captive in Irons!....... 1870. Large folio, broadside, 40 lines, 570 x 240 mm., minor loss to border and edge tears professionally restored, a very good copy of a rare poster. Surratt had escaped to Canada where he enlisted as a Papal Zouave. He then fled to Egypt where he was arrested and returned to the United States for trial. He was acquitted and released. The broadside assures readers that he "will most positively deliver his lecture in Washington" and will "give a full and truthful account of his thrilling adventures during the Rebellion, his introduction to J. Wilkes Booth, and the plan arranged to kidnap, not murder President Lincoln..." He attacks the judges and the false witnesses in the conspirators' trial and gives an account of his arrest and acquittal. Many historians believe that Surratt was a co-founder of the conspiracy with Booth.
