The 'Battle of Yalu River', (Japanese: 鴨緑江会戦, ''ŌryokkŠKaisen'')
30 April to
1 May 1904, was the first major land battle during the
Russo-Japanese War. It was fought near Wiju (modern village of
Uiju,
North Korea on the lower reaches of the
Yalu River, at the border between
Korea and
China.
The Russian Situation
The
Russian commander in the Far East,
General Alexei Kuropatkin's strategy was to only engage the Japanese in defense stalling actions, while waiting for enough reinforcements to be brought up to the front via the single-track
Trans-Siberian Railway to take the offensive. He had estimated that it would take at least 6 months to build his forces up to suitable levels. He also had received strict orders not to hinder the Japanese progress through Korea from
Viceroy Yevgeny Alexeiev, but to hold the line at the Yalu River to prevent the Japanese from crossing into
Manchuria.
On
22 April 1904, Kuropatkin dispatched the “Eastern Detachment†under the command of
Lieutenant-General M.I.
Zasulitch with 16,000
infantry, 5,000
cavalry and some 62
artillery pieces to fight a static delaying action at north bank of the river. However, this force was spread out piecemeal over a 170 mile front, whereas the Japanese Army could concentrate its efforts on any single point of its choosing. Furthermore, General Zasulitch did not hold the
Japanese in a very high regard.
The Japanese Situation
After the success of the
Imperial Japanese Navy at the
Battle of Chemulpo Bay on
9 February 1904, the way was clear for the
Imperial Japanese Army to deploy the 2nd, the 12th, and the Guards Divisions of the
Japanese 1st Army, commanded by
Major-General Baron Tamemoto Kuroki, into
Korea. The total strength of Japanese force was about 42,500 men. The Japanese 1st Army advanced quickly northwards from
Chemulpo (modern
Incheon), with advance units entering
Pyongyang on
21 February 1904 and
Anju by
18 March 1904. Learning their lessons in logistics and transport from the
Sino-Japanese War, the Japanese army hired some 10,000 local laborers at wages well above the local norms, and paid also for any food and supplies procured locally. This contrasted greatly with the behavior of the Russian troops previously in northern Korea.
By seizing the port of Chinampo (modern
Nampo, North Korea)at the mouth of the
Taedong River outside of Pyongyang with the spring thaw, the Japanese were able to land the remaining components of the 1st Army by
29 March 1904.
The Japanese knew the exact locations of the Russians deployment from intelligence by forward scouts disguised as Korean fishermen, as the Russians made no effort to conceal their positions. By
21 April 1904 the Japanese 1st Army was concentrated and hidden south of Wiju. The Japanese were in the same positions on the southern bank of the Yalu River that they had been in August 1894.
Prelude

The prelude to major action took place at 2145 on the night of
25 April 1904, when two battalions of the Japanese 2nd Division seized two islands in the Yalu River without opposition. After reinforcement at 0400 on
26 April 1904 by units from the Guards Division and a brief firefight, the forward Russian observation post withdrew to the main Russian lines on the north shore. In full view of Russian positions, the Japanese began constructing a
causeway across the Yalu River, which was immediately targeted by two Russian batteries. With the Russians so engaged, the Japanese prepared nine other bridges that could quickly be moved into position for a rapid assault across the river at other locations.
Once the midstream islands were secured, General Kuroki ordered a feint on the lower Yalu River when Japanese gunboats engaged
Cossack detachments at the river mouth. This convinced General Zasulitch that the main Japanese attack would fall on the vicinity of the town of
Antung, and he concentrated his forces there.
Kuroki was thus able to maneuver against the weak Russian left, and deployed the 12th Division and Guards Division across the Yalu River at a fordable point at
Chukyuri. The Russians observed these movements with trepidation, and the local commander informed Zasulitch that the Japanese were about to assault the position in force and his position was in danger of being flanked. Zasulitch chose to ignore the reports, thinking that the attack was only a feint redeployed a single battalion with four guns. Zasulitch remained convinced that the main Japanese attack would fall at Antung, and kept his main force as well as his reserves at that location.

Japanese Troops Crossing the Yalu River
The Japanese main attack began in the early morning hours of
27 April 1904. By 0300, the balance of the 12th Division had crossed the river and was advancing in three columns. While the Japanese 12th Division advancing on the right, the Guards Division was moving into position in the center. By 0400, the artillery of the Guards Division was within range of the exposed Russian lines. The Japanese First Army continued its three-pronged advance and was across the Yalu by midnight of the
29 April 1904 with very little opposition. Limited visibility masked the Japanese movements from Russian observation. When the fog finally lifted about 0500, the Japanese
artillery opened up on the Russian formations.
The 2nd Division took its position on the center, advancing on the newly erected causeways leading from the town of Wiju and thus catching the Russians in a pincer movement at the hamlet of
Chuliengcheng, on the Manchurian-side of the Yalu River opposite Wiju. By 1000, the Russians were in full retreat, with a Japanese attempt to block their escape towards
Fenghuangcheng to the north.
The Japanese had a number of 4.7 inch
howitzers, custom-made by
Krupp, which they used with devastating effect on the exposed Russians. In light of these developments, General Zasulitch was strongly encouraged by his staff to pull back to a more defensible position. However, the general stubbornly refused to concede, even sending a telegram to the
Tsar in
Saint Petersburg informing that victory was soon certain. He chose to ignore General Kuropatkin's phased withdrawal orders (as confirmed by Kuropatkin's chief of staff, General V.V. Sakarov).
General Kuroki had planned to continue the advance of 12th Division to envelope the Russian left. However, now that enemy artillery had been neutralized, he decided to engage the Guards and the 2nd Division in a simultaneous assault. It was at this point the Japanese encountered the first serious resistance from the Russian lines. The advance of the 2nd Division was disrupted for a time, and had any of the Russian artillery survived, the outcome might have been different. The Russians were driven from their lines with severe losses, and the survivors fell back to the position that Zasulitch’s advisors had unsuccessfully encouraged him to fall back to earlier. During the retreat, a counterattack was made by elements of the Russian
12th East Siberian Rifle Regiment, which was cut to pieces and opened further the breaks in the Russian lines.
The Russian position now became wholly untenable, and remaining formations now were in danger of being encircled. At the appearance of the Japanese 12th Division the Russian left flank panicked and collapsed.
This development was initially unknown to central command on the Russian right flank. General Zasulitch and his command staff with what remained of the his army was forced into a narrow gorge, where upon the advance of the Guard Division and 2nd Divisions, coupled with arrival of 12th Division, the Russians found themselves penned.
At 1730 on
1 May 1904, the remnants of the Russian Eastern Detachment surrendered and the Battle for the Yalu River came to an end.
Outcome
The Battle of the Yalu River ended in victory for Japan. The combat had cost the Japanese 1036 dead and wounded out of the total 1st Army strength of 42,500 (although it is possible that the total Japanese casualties were deliberately deflated for propaganda purposes). The Russian Eastern Detachment suffered some 2700 casualties overall, including about 1,400 killed in action and 600 prisoners and the loss of 21 of 24 field guns.
Importance
The Battle of the Yalu River was the first major land campaign of the Russo-Japanese War. The destruction of the Russian Eastern Detachment removed the perception that the Japanese would be an easy enemy, that the war would be short, and that Russia would be the overwhelming victor.
