The remaining conspirators were arrested by month's endexcept for John Surratt, who fled to Quebec where Roman Catholic priests hid him. In September, he boarded a ship to Liverpool, England, staying in the Catholic Church of the Holy Cross there. From there, he moved furtively through Europe until joining the Pontifical Zouaves in the Papal States. A friend from his school days recognized him there in early 1866 and alerted the U.S. government. Surratt was arrested by the Papal authorities but managed to escape under suspicious circumstances. He was finally captured by an agent of the United States in Egypt in November 1866.
