At Gefrees, the Austrians under Kienmayer had 2 regiments of regular Grenzer troops (about 5,300 men) and several hundred irregular Landwehr militia. The Black Brunswickers remained to the north guarding against any move by Jérôme and were not engaged at Gefrees. The French under Junot, on the other hand, had 2 regular line infantry regiments (about 6,000 men), a Bavarian depot battalion (about 1,000 men), and a dragoon regiment (about 500 men and horses). However, Junot's Corps of Observation of the Elbe were mainly conscripts who were poorly trained in comparison to the Austrian Grenzers. In particular, Junot's cavalry was not able charge effectively, therefore failing to exploit the lack of Austrian cavalry, and allowing the Austrians to remain in line formation. This meant the Austrians were able to deliver heavy and sustained volley fire throughout and by the end of the day, most of the French infantry had fled the field of battle. The Austrians had only suffered minimal casualties, whilst inflicting a substantial blow against the French. Junot's pursuit was not only stopped, but he was forced to retreat to Amberg.
