The latter therefore had to stand fast in the face of the Russian Eastern Detachment, which was three days' march at most from Feng-hwang-cheng and could be supported in three more days by Kuropatkin's main body, whereas the pressure of Oku's advance would not begin to be felt by the Russian Southern Detachment until the twelfth day at earliest.
In fact, Oku's march began on June 13th, Kuroki's on June 24th; the moves of the intermediate forces at various dates within this time.
Oku's 2nd Army (4 divisions or 60,000 combatants) was about Port Adams. This last was the objective of the attack of Stakelberg's 35,000.
But Oku's 2nd Army was now at a standstill at Kaiping, and until he was further advanced the 1st Army could not press forward.
Reorganizing his southern defences on a shorter front, so as to regain possession of the reserves that he had so liberally given away to his subordinates, he began to collect large bodies of troops opposite Kuroki, while Stakelberg and Zarubayev, before withdrawing silently into the lines or rather the fortress of Liao-Yang, again repulsed Oku's determined attacks on the south side.
Nogi landed on the 1st of June, and his army (1st and 11th divisions) gradually separated itself from Oku's and got into position for the advance on Port Arthur.
He wished to inflict a severe blow before the enemy could be reinforced by the late besiegers of Port Arthur, and sent Grippenberg with seven divisions against Oku's two on the Japanese left.
