Camillus joined the Venetian army while still only a youth. After his regiment was disbanded in 1574 Camillus worked in a hospital for uncurables, however his aggressive nature and excessive gambling led to his dismissal. He rejoined the Venetian army and fought in the war against the Turks in 1569. After the war he later returned to the hospital in Rome from which he had been dismissed, he became a nurse and later director of the hospital.
