When he learned of the assassination, Surratt fled to
Montreal,
Canada East, arriving on April 17, 1865. He then went to
St. Liboire, where a Catholic priest, Father Charles Boucher, gave him sanctuary. Surratt remained there while his mother was arrested, tried, and hanged in the United States for conspiracy. Aided by ex-Confederate agents Beverly Tucker and Edwin Lee, Surratt, disguised, booked passage to England under a false name. He landed at
Liverpool in September, where he lodged in the oratory at the Church of the Holy Cross. Surratt later served for a time in the Ninth Company of the Pontifical Zouaves, in the
Papal States, under the name John Watson. An old friend, Henri Beaumont de Sainte-Marie, recognized Surratt and notified papal officials and the
US minister in Rome,
Rufus King. On November 7, 1866, Surratt was arrested and sent to the
Velletri prison. He escaped and lived with the supporters of
Garibaldi, who gave him safe passage. Surratt traveled to the
Kingdom of Italy and posed as a Canadian citizen named Walters. He booked passage to
Alexandria, Egypt, but was arrested there by US officials on November 23, 1866, still in his Pontifical Zouaves uniform. He returned to the US on the
USS Swatara to the
Washington Navy Yard in early 1867. ==Trial==
