In the most flattering account, the Corsicans began the attack, splitting their forces to send 2000 men across the bridge against a much superior force, hence their reputation for bravery. Discovering the foolishness of their choice, they attempted to retreat across the river but for an unknown reason were met by the volley fire of the Prussians. Apparently, the shooters believed they were stopping an unauthorized retreat. Fortifying themselves as best they could, the majority of the 2000 died in the crossfire. Seeing their defeat, the confused troops on the other side retreated in disorder, pursued by the French.
