In 1647, St. Vincent de Paul sent Father Jean Le Vacher to do missionary work among the Catholics enslaved by the Barbary Coast’s Muslim corsairs and he arrived in Tunis during an epidemic of the plague and did much to comfort the captives. Upon the death of the French consul, the Bey appointed Father Le Vacher as his replacement.
