On one occasion in 1841, he rode between them at imminent risk to his life and by the sheer force of a stronger will stopped the conflict. On another occasion he rescued 700 American missionaries from Mount Lebanon and took them to Beirut walking himself all the way so that his horse could be available to old women.
