On the far-right flank of First Army, the Polish 45th Landwehr Infantry Division would support the advance of the 24th Infantry Division to its left while maintaining contact with Fourth Army’s 4th Infantry Division to its right. When both of those divisions moved forward, the Landwehr outfit did so as well, attacking across the narrow Por Brook to drive back the Russian reservists who had just entered the front line.

The Poles stormed across the stream, to be met by heavy rifle and machine-gun fire. They gained a lodgment but Russian counter-attacks tossed them back over Por Brook. X Corps commander Gen. Hugo Meixner von Zweienstamm dispatched reinforcements in the form of a cavalry division and a Landsturm brigade. Before they could make their presence felt the Russians withdrew on their own, to keep aligned with the division to their own left which had been pushed back by the Austrian Fourth Army’s attacks.
