Input (English): One of the losing generals in this battle was drunk, and his withdrawal was strongly covered by Kienmayer until he too was forced to retreat. This battle was preceded by the capture of General Mack and his army, which provided the advantage the victor needed, and the actions of Bxhowden during it didn't help. After a forced march that covered 80 miles in 50 hours, the III Corps under Davout arrived, allowing the IV Corps under Soult to take a position that the victor of this battle had feigned conceding, the Pratzen Heights. For 10 points, name this battle, in which Napoleon I decisively routed Alexander I and Francis II on December 2, 1805.
Output (English): History
