Breath frosted in the frozen morning as students grunted and groaned as they pushed the onager into position. The onager had taken a month to construct by the physics students, who would operate it.
Alex’s class had been divided equally to help the physics students with historical accuracy, right down to the correct rope to provide torsional power to the catapult. The other half of his students lay up ahead behind the snow wall that took up half the campus quad. The goal was to replicate part of Julius Caesar’s siege of Alesia. The Roman fortifications were made of snow instead of wood, but it would help the architecture students understand load bearing and exceptional stresses on structures.
