Despite Kildare's strict orders for his men to shoot Italian deserters on sight, the Canadians take kindly to a pair of buffoonish Italian deserters, more notable for their culinary skills than military prowess. Impetuously, Kildare orders the Canadians to execute the Italians. The Canadians are caught between the obligation to follow orders and the sense that executing the two Italians in cold blood is ethically unjustifiable—not to mention it being a violation of the Geneva Convention. The brutal execution of the two Italians forces the Canadians to confront the ethics of warfare, now that "the enemy" is no longer a distant and faceless target. Major Bunny Bazin, the most battle-hardened and philosophical of the Canadians, voices the novel's central theme when he states that "execution is... the ultimate degradation of man." Here the term "execution" works both literally (the killing of the Italians as a brutal act) and as a metaphor (war as a form of mass execution).
