How is Urbain treated differently in military school in the novel, War and Turpentine?

When Urbain enrolls in military school, he is treated with disdain by his French superiors, who deliberately mispronounce his name and are indignant when he attempts to correct them. The treatment continues when Urbain goes off to fight in WWI, where the Flemish soldiers are routinely subject to inferior treatment as a result of their cultural background, and where Urbain is dealt the loss of a medal of valor because of his Flemish background, having been given a false medal instead.
