"Baron followed his goal to serve with the renowned Robichauld, just as his father did before him, but the bloodshed he has seen now causes him to back away."
— Call of Duty 3 bonus materials section.
Baron, serving as a radio operator under Lt. Robiechauld, is routinely criticized by Robiechauld, who believes him to be a coward for not engaging the Germans directly. Baron argues that his job is to protect the radio- without it, his unit will have no direct link to higher command. Baron receives orders via the radio saying that they are to take an industrial area nearby, but they soon face a major force of German troops that were in the area already.
After the battle at the industrial yard, Baron is sent to Mount Ormel to replace the Polish radio operator who was killed in action. He attempts to argue against being sent away from his unit, but Lieutenant Robiechauld coldly dismisses him, pointing in the direction the Polish are and saying, "Get going!". While there, Baron calls in artillery strikes on the Germantanks as Bohater directs. During an intense firefight with the Germans, Ulan tells him to "Get out of here". Baron refuses, saying "My job is to call artillery strikes". Tired of being accused of cowardice, Baron continues to hold his ground as the Germans advance, despite the Polish soldiers around him arguing that he is running away from bullets, not from his job. Baron is killed by the advancing Germans moments later, but the Polish soldiers take his radio, enabling them to continue calling in badly needed artillery support.
