- In southern Poland the German and Austro-Hungarian commanders believe that the Russians intend to offer serious resistance on the new defensive line they retreated to yesterday.  As such, Mackensen instructs the German 11th Army to prepare a major assault for tomorrow, while the Austro-Hungarian 4th Army on the left flank and the German Army of the Bug on the right flank continue to advance, so as to be in position to support the main attack tomorrow.  While the latter is able to advance at Strzelce and capture a stretch of the road leading to Cholm, the former is unable to win significant ground in a series of sharp battles.
