Benjamin Franklin and Father John Carroll, SJ became friends on an ill-fated mission to Canada in 1776 during the opening stages of the Revolutionary War. The Continental Congress sent Franklin, Charles Carroll of Carrollton, Samuel Chase, and Father John Carroll on a mission to try to persuade the Canadians to join in the rebellion. Franklin was already ill when the trip began, and his condition worsened. He chose to leave Canada early when it was obvious that the mission would not succeed, so Father John Carroll decided to accompany him to help nurse him on the voyage. Franklin credited Carroll's ministrations with saving his life, and he never forgot Carroll's kindness and care. Because of this friendship, when Ben Franklin was the American ambassador to France, and the Church was looking to establish a hierarchy in the new American nation, he was in a position to put in a good word for Carroll. In 1784 Carroll was named "Superior of the Missions," and then in 1789 he was named the first bishop of Baltimore. He became archbishop of Baltimore in 1808, and died in 1815
