When World War I started, four friars from this community were selected for military service in the Italian army. At that time, Padre Pio was a teacher at the seminary and a spiritual director. When one more friar was called into service, Pio was put in charge of the community. On 15 November 1915, he was drafted and on December 6, assigned to the 10th Medical Corps in Naples. Due to poor health, he was continually discharged and recalled until on 16 March 1918, he was declared unfit for service and discharged completely.
