Professor John D. Hosler’s fascinating book on the siege of Acre during the Third Crusade provides a brief, but interesting, consideration of the interactions that sometimes took place between combatants during the siege. Regardless of the violence of the siege, Hosler notes that “the spaces between the ramparts…were not necessarily a zone of death.” The shared experience that Muslim and Christians troops who took part in the lengthy and bloody siege (lasting from 1189-1191) could sometimes lead to “noticeable expressions of respect, and even an adversarial camaraderie.” Hosler describes two examples found in the sources.
