When Charles Mallison explains Gualdres' reason for enlisting in the fight against Nazi Germany, he includes among the possible reasons the fact that the Germans "were rendering a whole race into fertilizer and lubricating oil" - an odd and perhaps callous way to refer to the Nazi campaign to exterminate the Jews of Europe (255). (Gualdres' actual reason, according to Charles, is that the Germans "had abolished horses from civilized cavalry," 255).
