ドライゼ銃
Having been ordered by Glabenz to march towards Radec and not knowing the outcome of the fighting at Burkersdorf (Střítež), Colonel Grivicic at 12:00 AM reached the town of Rudersdorf (Rubínovice), where he stood poised between the 1st and 2nd Prussian Guard Divisions. At Rudersdorf Grivicic encountered a Prussian battalion which had been detached as flank protection. Assuming he was faced by an entire division, Grivicic took up a defensive position against the Prussian battalion. By 1:00 PM, having understood his mistake, Grivicic restarted a cautious advance against the Prussian line, which had been reinforced by a second battalion and later by the 4th Guards Brigade. Failing to make headway against the Dreyse needle gun, Grivicic halted the advance and then retreated towards the town, which was then fought over house-to-house. As three new Prussian Guard battalions appeared and turned his right flank, making the brigade collapse and disperse. In all, Grivicic brigade lost 2512 men and was effectively destroyed.
