LAST ACT: The Attack of Dohna's Wing, August 25, 1758 As the title suggests, this is the last act of the bloody drama at Zorndorf. As with any last act worth its salt, it is also the most compelling. It begins with Dohna's infantry command advancing toward the position occupied by the Russian Observation Corps and instead being taken in the flank by Demicoud's cavalry thundering down upon them and being rescued by the timely arrival of dragoons (Plettenberg and Alt-Platen) from the Prussian left. Infantry, cavalry and artillery are very closly intermingled, making for some very desperate and costly fighting.
