Napoleon Bonaparte was the political leader of the French military and one of the early masters of the Minions in early 19th century.
After the accidental death of the Count Dracula, the Minions found another master to serve for, and they joined the troop of Napoleon's. At the winter in 1812, Napoleon led his army and the Minions to invade Russia. After hearing the order, one of the Minions lit a cannon while another Minions stands on it. The weight caused the cannon to lean and points to Napoleon, who stood in front of the troop.
The cannon fired soon, hit Napoleon and throws his toward. The French soldiers started to chase the Minions, and they fled successfully while the soldiers were stranded because the snowy weather hid everything around. Later, the Minions found an icy cave so they established their own civilation there.
