The Austrian Colonel Hertwegh was supposed to occupy the next village of Vysokov so as to block the road, but instead, when at 9:00 AM he got to Václavice (Wenzelsberg) he on his own initiative wheeled right to attack the Prussians on the ridge above; the King’s Grenadiers simply mowed his men down. It was now that the superiority of Prussian equipment made itself felt. Their new breech-loading needle guns enabled them to fire three shots to the Austrians’ muzzle-loader's one. The Prussian cavalry now rode forward along the road to stop the Austrians reaching Vysokov, and here a cavalry battle developed.
