On 19 January, Kuropatkin issued orders for the Second Manchurian Army to attack in a maneuver to outflank General Oku's Japanese Second Army and to drive it back across the Taitzu River before Nogi's Third Army could arrive. However, Gripenberg was not allowed to commit all of his forces – Kuropatkin limited him to three divisions plus the 1st East Siberian Army Corps and cavalry. The Japanese were aware of these plans, causing Ōyama to reinforce his left flank. Kuropatkin afterwards blamed premature moves by Gripenberg for alerting the Japanese.
