An officer in the Canadian Army during World War I and part of Xavier and Elijah’s unit. The men in Xavier and Elijah’s unit refer to Lieutenant Breech as “Bastard Breech,” as he is exceedingly unpleasant and racist. He scolds Xavier on the ship on the way to Europe when Xavier is forced to kill two wounded and suffering horses. “You will never become an officer,” Breech says to Xavier. Breech claims that Xavier and Elijah’s “Indian blood” is “closer to that of an animal than that of a man,” and he frequently sends them out ahead of the unit to scout for danger before sending in the other soldiers. He repeatedly refuses to give Elijah and Xavier credit for their kills as snipers because they are Indians and can’t be trusted. Lieutenant Breech makes Elijah and Xavier miserable for much of the war, and Elijah later kills Breech by clubbing him over the head when Breech finds out that Elijah has been scalping his kills and is addicted to morphine. Lieutenant Breech represents the widespread racism and hostility that Indigenous people must endure in broader society.
