Medieval wars killed infidels rather than converting them

Evidence

The anonymous author claims that converting Saracens to Christianity is easy and that he himself has baptized “a good thousand.” William of Tripoli concluded his Notitia de Machometo with dire semiapocalyptic predictions of the demise of Islam largely through military conquest: a third of the Saracens will perish by the sword, a third will perish in the desert, and a third will flee to Christianity. The anonymous author of De statu indeed includes this same prediction; yet he concludes his tract with the assertion that preaching the word of God will suffice to bring Saracens to the Christian truth, explicitly rejecting the twin strategies of military crusade and philosophical argument. — John V.

Roger Bacon was one of the most avid readers of the Itinerary of his fellow Franciscan William of Rubruck. Bacon attempts to turn William’s debating strategy into a veritable science of religion, bent on converting the infidel through rational argumentation. … For Bacon, the fruits of centuries of crusade and mission were scant: “there are few Christians; the whole breadth of the world is occupied by unbelievers, and there is no one to show them the truth.” No one, that is, until Roger Bacon came along. War does not win converts; it kills infidels and sends them to hell, making the survivors all the more hostile to Christianity. More often than not, crusades fail to meet their military goals, as the expedition of Louis IX so painfully illustrated. Bacon is not a complete pacifist; military defense of the Holy Land is legitimate, and he even suggests the use of high-tech mirrors to create fires in the enemy camp. But it is preaching and philosophical argument, not war, that will win converts to Christianity. — John V. Tolan, Saracens, 1144 (#contradicts, via linked claim)
