3.183 Fall and Rise of China: The end was near for Changkufeng

Last time we spoke about the second Russian Counter Offensive over the Heights. Night operations opened the action: scouts moved in darkness, wires were cut, and Hill 52 fell before dawn, followed by Shachaofeng as dawn pressed the front. The Russians responded with a heavy counterattack, tanks, aircraft, and sustained artillery, yet the Japanese adapted quickly, shifting guns and reinforcing sectors to hold the crest. By 3–5 August, Japanese and Soviet forces fought in a fragmented front across multiple sectors: Hill 52, Changkufeng, Shachaofeng, the lake. Japanese commanders coordinated between infantry, engineers, and mountain artillery, while seeking long-range support from Kwantung Army. Soviet artillery sought to disrupt lines of communication and press from the Crestline with massed tanks and air strikes. Despite intense bombardments and repeated tank assaults, Japanese regimental guns, antitank teams, and close-quarters defense bore the brunt of the defense, inflicting heavy Soviet losses. Yet in the end the Japanese had yet again repelled the enemy from the heights.

While the front-line fighting raged on 6 August, Tokyo moved to supply the 19th Division with the coveted long-range artillery and antiaircraft support. In the evening, the Korea Army officially learned from the AGS that, by Imperial order, the Kwantung Army would add the strength already informally approved: four 7.5-centimeter field guns, two 15-centimeter cannons, two 10-centimeter railway guns, and two 7.5-centimeter antiaircraft guns. The North China Area Army would also provide mobile antiaircraft units. The Korea Army estimated that the field and heavy artillery reinforcements would reach the town of Tumen on 7–8 August. The new guns were expected to ease the division’s pressure in due course. The fighting continued on the 7th. The 75th Infantry observed that, despite the Russians’ vigorous attacks aimed at capturing Hill 52 and Changkufeng on 6 August, they failed at both objectives and were repelled with heavy losses. Because of the Soviets’ ignominious defeat at Changkufeng, they seemed determined to seize Hill 52 on 7 August.

Most of the shallow and isolated Japanese positions at Hill 52 had been shattered by bombardments. Some men retrieved Japanese corpses still piled atop one another; the wounded were to proceed to the rear by themselves. Many had not eaten since the morning of 6 August, yet morale remained high. It was decided to knock out the Soviets’ advancing tanks under the cover of darkness, employing infantry and engineers. At 03:00, these elements moved against the armor 150 meters behind the Russian wire, killed some advancing infantry, and destroyed two tanks. The infantry platoon leader, Warrant Officer Kanaoka, jumped aboard a tank, pried open the turret, and fought with his blade as blood dripped from the blade. The eastern sky brightened as he stood there smiling and holding his bloodied sword; at that moment, Private First Class Kimura exploded a grenade inside the tank, which promptly blew up. The assault force returned safely at dawn.

At dawn, from heavy-weapon positions 200–300 meters in front, the Soviets opened fire, exploiting gaps between the smashed armor. Since 04:00, sixty Russian tanks had been moving south on the far side of Khasan. By daybreak, more than ten machines could be seen in the dip northeast of Hill 52, with several dozen other tanks newly active along Hill 29 Crestline as infantry deployed in gullies. At 05:30, Russian artillery began firing from all directions. In addition to shelling from Gaho, Hill 29, and Maanshan, the Soviets directed flank fire against Hill 52, using two rapid-fire guns 700 meters northeast and three mountain guns on the slope of Changkufeng. As the works at Hill 52 were progressively pulverized, K. Sato dispatched reinforcements from the 76th Regiment there. Near 11:00, the Russian barrage intensified and became more accurate; positions were destroyed one by one, and casualties rose. A new apex of fury occurred between 13:30 and 14:30, when a pall of smoke blanketed the region, producing a ghastly impression. Russian planes bombed and strafed Hill 52 from 11:00; a raid by twelve bombers against the western slope at 13:30 was particularly fierce, though many bombs fell harmlessly into the Tumen.

The Russian lines were built up gradually, and all types of Soviet weapons were employed. From 14:30, about 100 Russians approached, led by four tanks, and penetrated the defense positions. Close-quarter counterattacks were launched by elements of three Japanese infantry companies, a machine-gun platoon, and an engineer platoon. One officer recalled “It was tough and costly fighting. Men were overrun by tanks, some losing limbs.” Nine engineers linked up with the infantry, placing explosives under tank turrets and blowing up two machines. During the crisis, with tanks and infantry overrunning his lines. From the right wing, in the Eleventh Company sector, the Japanese fought fiercely against Soviet heavy weapons and infantry who had advanced to point-blank range. Master Sergeant Suzuki, acting company commander, on his own initiative ordered the main force to counterattack. Through coordinated action, the Japanese knocked out four tanks that had penetrated their positions. Two enemy battalions that had “come close bravely” were nearly wiped out. Total Soviet strength committed in this sector amounted to three battalions and forty tanks. Japanese losses on the Hill 52 front were heavy indeed: seventy-four had been killed and eighty-five wounded, one hundred fifty-nine out of three hundred twenty-eight men in action. The remnants of one infantry company were commanded by a superior private; sergeants led two other infantry and two machine-gun companies. Seven of thirteen heavy weapons were inoperable. 

Meanwhile 9th Company elements defended Noguchi Hill, 800 meters southeast of Changkufeng. By 05:00 on 7 August, Soviet troops facing the hill numbered 200 infantry, five tanks, and two rapid-fire guns. From positions set up the previous night along the lake, the Russians opened fire at dawn while 50 soldiers moved to attack with the tanks in support. Captain Noguchi’s men poured fire on the enemy and inflicted heavy losses. But the Russians, who possessed superior supporting fire, fought their way forward until, after 40 minutes, they got within 70 meters. The Soviet tanks disappeared into a dead angle near the lakeshore. When the fog lifted at 06:00, the Russians on the southeast slope of Changkufeng fired down at Noguchi Hill with four heavy machine guns. Seven tanks, advancing anew from the gully northeast of Hill 52, came as close as 80 to 200 meters, deployed to encircle, and opened fire. By now, eight Japanese had been killed and five wounded; most of the light machine guns and grenade dischargers had been crippled and all three heavy weapons were out of action. The Russians attacked again at 08:00, hurling grenades and shouting. A dozen tanks operated in support of two infantry companies. The Japanese responded with grenades; yellow and black smoke masked the heights, and the scene was extremely impressive. Desperate hand-to-hand combat raged along the sector for a half-hour until the Soviets fell back after suffering enormous losses. 

At 10:40, the Russians assaulted with infantry from the southeast front and from the Changkufeng direction, aided by tanks from the zone between. Captain Noguchi sortied with his remnant, charged the Russians, and drove them off. In this fighting, however, he was shot in the chest and most of his subordinates were killed or wounded. Somehow the captain stayed on his feet. He and six survivors threw grenades at the Russians, who were now behind the Japanese, and then he led a last charge back to the highest positions. Once the enemy had been evicted, Captain Noguchi collapsed. Only three or four soldiers were in fighting condition. The captain begged them to report to Sato, but, refusing to abandon him, the men managed to help him down to the rear. It was 11:30. Captain Noguchi’s unit, which had fought bravely since the first combat on 6 August, had been destroyed. Of 78 officers and men, 40 lay killed and another 31 wounded. The hill had been lost.

Meanwhile, Soviet bombardment of the Hill 52 district had been heavy, and phone contact with the regiment was severed. Suddenly, the indomitable Captain Noguchi appeared at headquarters, and the regiment finally learned that the foe had penetrated the defenses. The bleeding captain pleaded for a counterattack and kept trying to return to the fight; K. Sato had to restrain him by ordering him to leave for the rear. It was true that the position Captain Noguchi had occupied was the key point connecting Hill 52 and Changkufeng. But Sato reasoned that if they held solidly to the latter hills, their defenses would never be in danger, and it would be easy to retake Noguchi Hill at any time by concentrating fire from all the high ground and by employing artillery, once strength could be spared. Around sunset, however, Sato received an order from the brigade, and a report came from Changkufeng that “our troops’ brave fighting has tied us over the crisis.” Reassured, Sato proceeded to Hill 52, cheered on Kojima and the soldiers, and examined the condition of the wounded and the heaped-up corpses. 

The 75th Infantry estimated that there had been 900 Russian casualties in the right sector and that more than ten tanks and three heavy machine guns had been put out of action. The regiment itself had lost four officers killed and had four wounded. In the entire right sector which included 1,332 men in action, 140 had been killed and 180 wounded. Seven soldiers of the 75th Infantry were also listed as missing in action but presumed dead. Total casualties including the missing, as a percentage of those listed as engaged, amounted to 25 percent for the right sector unit. On the 7th, the unit had lost 19 machine guns and 11 grenade dischargers.

As of 18:00 on 7 August, Japanese intelligence estimated that the Russians had committed a grand total of 25 infantry battalions, up six from 6 August, 80 artillery pieces, up 10, and 200 tanks . Situation maps showed one Soviet infantry battalion east of Changkufeng, another north of Hill 52, armor and infantry in unknown strength east of that hill, and artillery positions from northeast to southeast of Khasan. On the 7th, spotters also observed seven large steamers entering Posyet and Khansi, as well as one 10,000-ton vessel at Yangomudy. At least 200 or 300 enemy soldiers in the Karanchin sector were working to strengthen positions. Units moving south from Novokievsk included 350 trucks, 60 tanks, and 400 troops. Heading north from the region of the battlefield were 100 trucks and 150 horsemen. Meanwhile, on the front in eastern Manchuria, elements of the Kwantung Army’s 8th Division had forcibly ousted a small party of Soviet border trespassers.

The “punch” had gone out of the Russians in the Hill 52 sector after their thorough defeat on 6 and 7 August, but they continued to build up firepower, deploying heavy weapons and artillery observation posts. The bombardments grew more accurate; even regiment and brigade headquarters lost their last dead angles. By daylight on the 8th, two Soviet infantry battalions plus tanks were deployed on the Hill 52 front. Their main forces were distributed along a line 800 meters from the Japanese, and snipers and machine gunners held positions 200 to 300 meters away. “Each time they detected movement, they sniped at us and interfered with our observation.” From 09:00, the Japanese sustained scattered artillery fire. At 13:30 there was a bombing raid by 15 planes, but no casualties were incurred. Soviet guns pounded Hill 52 around 18:30, and the Japanese suffered four or five casualties, but morale was generally high, and they sought to strengthen and repair their positions throughout the night.

On the Changkufeng front, which had drawn rather serious attention, Russian heavy guns opened slow fire after 05:00 from east of Khasan and from Maanshan. Through the night of 7–8 August, Soviet infantry had assembled near the lake crossing. Russian troop strength increased beyond one-and-a-half battalions. The defenders ran out of grenades and had to resort to rocks, but by 10:00 the Soviet assault waves began to weaken after five hours of fierce resistance. Supporting the Japanese lines had been barrages by grenade launchers, flank fire by a heavy-machine-gun platoon at Chiangchunfeng, and supported by the mountain artillery. Around 10:30, the attackers fled to Khasan. The battlefield quieted, but enemy snipers dug foxholes 300 meters away and kept up persistent fire, and infantry mounted repeated attacks in varying strength. 

 

Since morning, the mountain gun and the two battalion guns at Fangchuanting had engaged infantry and machine guns that appeared on the middle of the Changkufeng crest as well as in the Hill 52 area. The timely fire from these guns caused severe losses, especially to Russian observation posts. But Lieutenant Maeoka, who commanded the mountain platoon from Changkufeng, was wounded badly at 10:30. The mountain battalion also fired at targets in the Changkufeng sector from the Korean side of the Tumen. At 13:20, the Russians pressed new attacks against Changkufeng from three sides, using a total of two companies and three tanks. Although they got close and attacked persistently, they were driven off each time; these afternoon efforts were not very vigorous. Fighters strafed at low altitude and more than ten bombers attacked near 15:00, igniting fires in the village of Fangchuanting. The raids by planes and guns caused frequent cuts in signal lines again. At 06:50 on the 8th, Soviet forces in the left sector resumed their efforts until they were pinned down at 100 meters and had to dig in. Excepting spotter posts, everyone must enter shelters from warning till all-clear. Meanwhile, T. Sato estimated that although enemy attacks were aimed mainly against Changkufeng, there existed some danger that hostile forces would cross the Tumen near Yangkuanping and launch a sudden attack against our left rear, as actions in that area had become pronounced. He accordingly issued an order at 17:00: all of us, superiors as well as subordinates, must overcome exhaustion, make nighttime guardings rigorous, and leave the foe not the slightest opening between friendly battalions or from the shores of the Tumen River. 

Suetaka estimated in the morning of the 8th that the Russians were trying to generate propaganda advantageous to them at home and abroad by staking their honor and seizing Changkufeng quickly. From the standpoint of overall political tactics, it was imperative to thwart their intentions. The enemy relied consistently on elements that remained on the Crestline southeast of Changkufeng and served as a base; they must be deprived of that attack base. If his assault plans were to be successful, the 37th Brigade would require reinforcement. The first battalion-size elements of Cho’s infantry were arriving. As an initial step, Hanyu’s battalion should cross the Tumen and join the brigade, while the main body of the regiment, due that afternoon, should be ready to enter the lines. The division chief of staff issued an order in the name of Suetaka, stipulating that the division would secure its positions while adhering to the great policy of nonexpansion. At 22:30 Morimoto speculated that the Russians were hoping for the good fortune of retaking Changkufeng. Strict guard measures were enjoined. Eventually, before midnight, Suetaka met Cho at Seikaku station.

To implement Suetaka’s request that the Russian foothold southeast of Changkufeng be wiped out soon, Morimoto decided in the morning to employ the new battalion from Cho’s regiment. But since Hanyu’s unit was delayed by enemy fire, Morimoto had to turn to the reserve 76th Regiment. At 16:00 Okido was told to prepare an attack, using one infantry battalion and an engineer squad. The mission was to take advantage of darkness to expel the foe remaining on Changkufeng, secure the heights in concert with the elements on the hill, and smash any serious attack at night. At 17:00 Okido issued his detailed order. Enemy elements were located near the cliff close to the northern top of Changkufeng. Apparently hostile bases existed in scattered fashion on the southern slopes as well, as well as a rather large base on the middle of Akahage “Red Bald” Hill, formerly held by Captain Noguchi’s company. The regiment was to drive those forces north of Hill 52. The 3rd Battalion commander, Major Hashimoto Seishiro, was to direct both companies’ assaults, and, once the foe had been ousted, secure the locations until dawn, after which he would return to the reserve unit. 

On the 8th, at 19:30, Hashimoto proceeded with his battalion staff to the foot of Changkufeng and conferred with Major Sato and Captain Shimomura, the majors commanding the units with which he was to cooperate. The assault units moved out from Chiangchunfeng, but their timing was thrown off by a half-hour of artillery checking fire from northeast of the lake. At 20:50, Captain Iwai’s 10th Company, supported by a machine-gun platoon, attacked the rock corner on the east side of Changkufeng. After cutting down Soviet sentries, the Japanese rushed in; 40–50 Russian soldiers retreated toward Akahage. On that hill there had been only 20–30 Soviet troops to begin with, but their strength had been built up to two companies plus tanks and infantry guns. The Russians laid down violent small-arms fire, causing 17 Japanese casualties in a short period, after which 30–40 enemy soldiers sought to counterattack. The Japanese drove back this effort, readied their own offensive, and continued to launch close assaults against the heavy-machine-gun nest at the rock corner. Simultaneously, Captain Shidara’s 7th Company jumped off with five attached demolition engineers. The 1st Platoon broke through the entanglements and cut down lookouts while the 2nd Platoon proceeded to mop up footholds on the north side—about ten Russian soldiers who dotted the slope at four locations. In the process, the company ran into the positions Iwai had been attacking. Terrain and enemy fire dictated a detour south of the ridgeline. Shidara’s men moved up behind Iwai on the right, joining Hashimoto’s command. The battalion commander consolidated his lines and directed reconnaissance preparatory to an attack against Akahage. Hours passed; Okido, at the command post, decided it might be wiser to wait till daybreak and call for artillery support. Hashimoto then issued his own instructions from the eastern salient, cautioning his men to dig in well. Near 04:00 the redeployments were completed, but construction did not progress due to the rocky terrain; soldiers were barely able to scoop knee-high firing trenches by daybreak.

Total Russian losses on the 8th were estimated to exceed 1,500. More than 100 tanks were claimed publicly, and it was “confirmed” that since the 1st, six planes had been shot down, two of which had fallen behind Japanese lines. In Tokyo, the war ministry and the Gaimusho denied categorically that the Russians had retaken Changkufeng. Soviet troops had attempted to rush positions 600 feet from the crest at 1400 hours; after two and a half hours of furious hand-to-hand fighting, they were beaten off with presumably heavy casualties on both sides. Soviet tanks were reported moving north from Posyet Bay, though it remained unclear whether this indicated withdrawal or strategic movement. Right sector casualties were relatively light on 8 August: eight killed and 41 wounded, the 75th Infantry suffering five and 38 of these respectively. Officer casualties were proportionately high: two wounded in the 75th Regiment, one in the 76th Regiment, and a fourth in the mountain artillery. Personnel rosters of the 75th Regiment, as of 30 July and 8 August, showed a reduction from 1,403 to 826, down 41 percent. The cumulative effect of Japanese losses and the scale of Soviet commitment troubled the Korea Army. Suetaka reported Japanese casualties as: through 2 August, 45 killed, 120 wounded; from 3-5 August, 25 killed, 60 wounded; since 6 August, killed unknown, 200 wounded. Remarkably, the same casualty totals were released publicly by the war ministry on the night of the 8th.

Throughout 9 August at 15:20 the Japanese were hit by a very intense barrage from Hill 29. The mountain gun was damaged by shellfire and had to be moved to the foot of Fangchuanting. Tanaka had ordered his artillery to conduct long-range artillery neutralization and communications-cutoff fire, and short-range neutralization as well as checking fire. The accuracy of our artillery elements had improved, and the power of our guns had been enhanced greatly. On the left, from 05:30, T. Sato dispatched an antitank platoon, under cover of mist, to finish off immobilized Soviet tanks whose main armament was still operational and which had done some severe firing the day before. As the day wore on, spirits rose, for the men heard the roar of friendly 15-cm cannon laying down mighty neutralization fire against enemy artillery. Near 14:15, Russian troops were detected creeping forward in the woods 400 meters away on the right. Supporting mountain artillery wiped out this threat in short order. Suetaka decided to move his division headquarters to Seikaku and his combat command post to the Matsu’otsuho message center. Anxiety about the Wuchiatzu sector to the north had diminished greatly; in addition, the entire strength of the division had already been brought to the front. Lastly, dealings with the Seoul and Tokyo levels had by now become rather secondary in importance. Suetaka could discern the steady, disturbing exhaustion of his front-line troops. On the other hand, newly arrived Cho was raring to go. After receiving authorization from Suetaka, Cho allowed Nakajima’s battalion to cross the river at Matsu’otsuho but kept Osuga’s battalion on the Korean bank as division reserve.

Since Tanaka had surmised that the Russians’ intention was to direct their main offensive effort against the Japanese right wing, it seemed best to transfer the mountain guns to strengthen the right sector positions. The brigade order of 17:30 endorsed Tanaka’s shift of defensive emphasis, particularly with regard to the artillery and the new elements from Cho’s regiment. Morimoto added that the core of the Soviet assault force southeast of Changkufeng amounted to two infantry battalions. T. Sato accordingly ordered Obo’s battalion to integrate its heavy firepower and deliver swift fire in timely fashion. Soon afterward, Obo discerned a massed battalion of Russian infantry, who had been hauled up by trucks, on the northeastern skirt of Changkufeng. He unleashed every available weapon, organic and attached, at 19:30. The Soviets seemed taken completely by surprise; they showed extreme bewilderment and dispersed in an instant. The right sector unit estimated that on 9 August it had caused 450 casualties, stopped five tanks, and knocked out one light artillery piece and seven heavy machine guns. Japanese casualties in the right sector had amounted to 28 killed and 43 wounded. Ammunition expenditures were considerably higher than on the 8th. 

During the night of 9–10 August, the 74th Infantry reinforcements crossed the Tumen steadily. In the early hours, Okido concluded that Soviet attack designs had been frustrated for the time being. The Hill 52 front was relatively calm. Soviet automatic weapons and riflemen were still deployed 200 to 300 meters from Japanese positions, where they sniped selectively. Russian artillery was quiet, apparently as the result of the movement of the main Japanese artillery force to the right wing and the arrival of long-range guns. The 75th Regiment command post at Fangchuanting was the focal point of Japanese artillery activity. Firing began at 07:10, when four battalion guns engaged and smashed two Soviet mountain pieces. 

As for Soviet ground assaults, one company attacked at Changkufeng as early as 05:20 under cover of fog but was driven off after 40 minutes. The Russians struck again from three directions in formidable strength between 09:00 and 10:00. Morimoto, growing concerned about the danger of irruptions through gaps between Changkufeng and Shachaofeng, sent elements of Nakajima’s battalion to Chiangchunfeng. Since the right wing of the Russians atop Changkufeng was spilling onto the western slopes, at 10:30 Nakajima had his heavy machine guns and battalion guns lay down strong fire from the peak of Chiangchunfeng. Meanwhile, heavy weapons from the left sector were also contributing to the repulse of the morning assaults. A battalion of Soviet infantry attacked Changkufeng all afternoon. Fierce gunfire by the 75th Regiment at 14:00 routed troops massing on the slopes facing the red flag. Considerable losses were inflicted on 75 Russians sighted northeast of Hill 52. An enemy company on the Khasan shore and another two east of Akahage Hill were attempting to occupy positions from which to strike Fangchuanting with the support of two rapid-fire guns. By 17:00 the Russians had been repulsed by the energetic fire of Japanese small arms, battalion guns, and artillery. Soviet forces dispersed toward the lakeshore and Hill 52, leaving many corpses behind. The last important firing by Japanese battalion guns at Fangchuanting on the 10th was a mission against the eastern slopes of Changkufeng at 18:00. Thereafter, the battle zone grew still. 

In the left sector, T. Sato concluded that, to secure Changkufeng, it would be best to reinforce flank fire instead of concentrating on the direct attack or defense of the Changkufeng district. He therefore made arrangements with Okido to borrow one machine-gun platoon and assign it to Obo. As of 05:30, enemy troops were still holding a line 300 meters from the positions of Obo’s right battalion and 800 to 1,000 meters ahead of Takenouchi’s left battalion. Shortly afterward, good news was received at the left sector command post: the last battalion of the 73rd Regiment was to have left Nanam at 16:00 on 9 August and would arrive in the near future. On the right wing of the left sector, the Russians facing Kadokura’s company began to operate energetically from 09:00, advancing in two lines, 150 meters apart, with a total strength of one company: two platoons up, one platoon back. They were supported by forces on the high ground north of Khasan and on Akahage. Kadokura waited for the enemy to close to 200 meters before ordering his men to open fire; particularly effective was the flanking fire by the machine-gun company and by elements of Okuda’s company. Many heavy artillery shells were hitting the Japanese lines now, but defensive fire pinned down the attacking infantry for a while, 100 meters from the breastworks. Then 30 or 40 Soviet soldiers, covered by firepower, worked forward as close as 30 meters, hurling grenades and giving every indication of mounting a charge. The Japanese responded with grenades. At the same time, the left-flank squad of Kadokura’s company was being annihilated. Thus encouraged, Russian assault troops plunged close, whereupon Kadokura assembled his available men, a dozen or so, from the command teams and runners—and grappled with the foe at point-blank range. An ammunition man joined in the melee and broke up the Soviet assault by expert use of hand grenades. The second echelon gradually fell back around 10:30, in the face of heavy fire laid down by the machine guns and Okuda’s company. The Russians appeared to be adjusting their deployment but made no further efforts to close. At Changkufeng, meanwhile, two or three enemy companies were approaching the crest. Left sector raiding fire caused the Russians to flee.

Japanese casualties in the old right sector had been nine killed and 22 wounded on 10 August. It was estimated that Soviet casualties amounted to 600 killed or wounded, with five heavy machine guns knocked out. By this time, the Soviets had committed their maximum infantry and artillery strength: 27 battalions and 100 guns, the same as on 9 August but up 17 battalions and 60 units since 3 August. Higher headquarters reported no tanks at the front, though 75th Infantry situation maps indicated some Soviet armor still faced Hill 52 sector. Although Japanese officers insisted that Changkufeng Hill remained in Japanese possession, they acknowledged increased casualties due to the accuracy of Soviet shelling. Losses were not as severe as might have been expected because the enemy did not time their charges with their bombardments; Japanese troops lay in trenches and met the attackers with grenades.

Every combat unit of the 19th Division had been committed. Nevertheless, the maimed and the fresh battalions had amounted to a combined maximum strength of only 12 infantry battalions and 37 artillery pieces, primarily 75-mm mountain guns, without armor or aircraft. These forces had to cope with 27 enemy infantry battalions and 100 artillery pieces, including many long-range guns, as well as sizable tank and aerial units. Every echelon, regiment, division, and army, had voiced the need for troop replacements and reinforcements. 

By evening of 10 August, the situation had deteriorated to the point that the division chief of staff sent Seoul a very long and painful message that ended with: “There is danger of radical change in combat situation in few days if matters go on. It is estimated that this division has only one or two days left in which it can retain definite freedom of action,initiative to advance or retreat. Even if overall situation should develop to our advantage in next three or four days, we ought to be patient from broader standpoint, and be satisfied with our achievement, that Japanese Army has manifested its strength against enemy till now. While we do retain freedom of action, it would be appropriate to solve incident now through speedy diplomatic negotiations. Such measures are entirely up to Korea Army and high command but, so far as division is concerned, there is no other way except of course to make desperate efforts to maintain occupation line for sake of mission. Please take these matters into sympathetic consideration and conduct appropriate measures urgently”.

Night raids and artillery opened the fight, with Hill 52 and Changkufeng changing hands amid intense Soviet tank and air assaults. Japanese forces, aided by engineers, infantry, and mountain guns, mounted tenacious defense, repelling repeated Soviet breakthroughs though suffering heavy casualties. By August 10, Japanese divisions faced mounting exhaustion and warnings of potential strategic shifts, while both sides suffered substantial casualties and material losses.
