On the Russian side, the overall direction of the battle was first exercised by General Nadein, and then by General Fok. On 24 May 1904, during a heavy thunderstorm, the Japanese Fourth Division under the command of Lieutenant General
Ogawa Mataji attacked the walled town of Chinchou (modern-day
Jinzhou District 金州), just north of Nanzan hill. Despite being defended by no more than 400 men with antiquated artillery, the Fourth Division failed on two attempts to breach its gates. Two battalions from the First Division attacked independently at 05:30 on 25 May 1904, finally breaching the defenses and taking the town. With his flank thus secure, General Oku could then commence the main assault on the entrenched Russian forces on Nanshan Hill. The assault was postponed a day due to the weather. On 26 May 1904, Oku began with prolonged artillery barrage from Japanese gunboats offshore, followed by
infantry assaults by all three of his divisions. The Russians, with
mines,
Maxim machine guns and
barbed wire obstacles, inflicted heavy losses on the Japanese during repeated assaults. By 18:00, after nine attempts, the Japanese had failed to overrun the firmly entrenched Russian positions. Oku had committed all of his reserves, and both sides had used up most of their artillery ammunition. Finding his calls for reinforcement unanswered, Colonel Tretyakov was amazed to find that the uncommitted reserve regiments were in full retreat: in the midst of battle Nadein ordered 2 battalions from reserve to occupy the empty trenches of the left flank, but for some reason only 2 companies were sent in. Tretyakov's remaining ammunition reserves had been blown up under orders of General Fok. Fok, paranoid of a possible Japanese landing between his position and the safety of Port Arthur, was panicked by a flanking attack by the decimated Japanese Fourth Division along the west coast. In his rush to flee the battle, Fok had neglected to tell Tretyakov of the order to retreat, and Tretyakov thus found himself in the precarious position of being encircled, with no ammunition and no reserve force available for a counter-attack. Tretyakov had no choice but to order his troops to fall back to the second defensive line. By 19:20, the
Japanese flag flew from the summit of Nanshan Hill. Tretyakov, who had fought well and who had lost only 400 men during the battle, lost 650 more men in his poorly supported retreat back to the main defensive lines around Port Arthur. ==Results==
