The German Third Army attacked towards Warsaw from East Prussia, but became entangled by the Mlawa fortifications. Panzer Division Kempf and two divisions of the 1st Corps were stopped by the Polish 20th Infantry Division. The Wodrig Corps could not flank the Polish position due to the swampy ground. Along the Ulatkowka river, Polish Uhlan cavalry (elements of 11th Cavalry "Legions'" Regiment) stopped attacks by the German 1st Cavalry Brigade. Rather than a mounted fight, most were dismounted. However, the Poles did stall the German Third Army advance.[1]:43

Sabers (on the Polish side szablas) were used.
