Having been able to shift the majority of his Corps westwards to Pilníkov, Glabenz left a regiment from Knebel's brigade behind as rear guard to hold up the Prussians at Burkersdorf.

[1] 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 hamlet of Rudersdorf (today Rubínovice within Trutnov-Starý Rokytník), where he stood poised between the 1st and 2nd Prussian Guard Divisions.

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.
