After preparing a fine dinner for the generals, who dined upstairs, Jean-Marc ate dinner with the Belgian motorcycle couriers assigned to relay French communications: Rocco, Claude, Alex and Henri Defense (Indiana Jones) . When Defense expressed his confusion over the participants in the war, Jean-Marc began illustrating the networks of opposing alliances that led all the major nations of Europe in the war. Using the food and other objects around him, he demonstrated the geography of the continent and showed the Austrian attack on Serbia by sprinkling the salt (representing Austria) onto a small tomato (representing Serbia), and then eating it.
