Last time we spoke about the Soviet invasion of Manchuria. Following the atomic bombings of Hiroshima and Nagasaki amidst relentless Allied aerial campaigns, chaos engulfed Japan. Prime Minister Suzuki's cabinet debated surrendering to avoid annihilation while fearing for the imperial family's future. Meanwhile, the Soviet Union launched an unexpected invasion of Manchuria, rapidly advancing and catching Japanese forces off guard. As negotiations unfolded, a group of military conspirators, led by Major Hatanaka, attempted a coup to halt the surrender, believing they could rally support. They seized the Imperial Palace but failed to find the Emperor's recorded surrender speech amid the chaos. In a decisive moment, Emperor Hirohito accepted the Potsdam Declaration, stipulating the emperor's continuation, thus sealing Japan's fate. That same day, the world learned of Japan's capitulation, marking the end of the Pacific War. The once powerful nation now lay in ruins, yet the Emperor’s decision bore the weight of a nation saved from further destruction, embodying a fragile hope for the future amidst the horrors of war.

As we previously discussed, the Japanese Empire made the difficult decision to surrender on August 14, amid the turmoil of the Soviet invasion of Manchuria and South Sakhalin. The following day, this decision was announced to the world. However, in Manchuria, General Yamada’s Kwantung Army chose to continue fighting until they received a clear ceasefire order. At this moment, several developments unfolded. General Hongo’s 44th Army was on a forced retreat toward the Hsinking-Mukden line under General Ushiroku's command, leaving their 107th Division trapped behind Soviet lines. Meanwhile, General Iida’s 30th Army was redeploying to Hsinking, which was starting to be evacuated, while General Uemura’s 4th Army had orders to withdraw to Meihokou, taking over positions left by the 30th Army. 

The advance of enemy armored columns in the west was severely hindering the evacuation of Japanese nationals. On the 10th, the Kwantung Army requested the Manchukuoan Government to facilitate the evacuation of Japanese residents in Hainking and its surroundings. They directed the Continental Railway Command to prepare ten trains for this purpose, with the first train scheduled to depart from Hsinking that same day. However, the Manchukuoan Government found it nearly impossible to carry out the withdrawal swiftly. They managed to transport only the families of officers and civilians linked to the army, and these families had to flee with just a few hours’ notice, taking almost nothing but the clothes on their backs. By the 12th, Hsinking was in a state of chaos. The advance of enemy armored units, coupled with the retreat of the main force of the 44th Army, led to the evacuation of the capital by the Kwantung Army General Headquarters. This turmoil coincided with the arrival of the first refugee trains, carrying Japanese evacuees from the western border areas, causing widespread panic among local residents. Many hurried to the already overcrowded train station, desperate to escape the unfolding crisis.

In the face of enemy pressure, the 80th Independent Mixed Brigade and the 119th Division continued to resist assaults at Hailar and Pokotu, respectively. The 123rd Division and the 135th Independent Mixed Brigade were heavily engaged in the fortified regions of Sunwu and Aihun, and the 136th Independent Mixed Brigade was directed to reinforce Tsitsihar, while the 134th Division retreated to Fangcheng. General Shimizu’s 5th Army prepared for a last stand at Mutanchiang, while the isolated 124th Division made plans to withdraw. The 132nd Independent Mixed Brigade had already retreated to Tachienchang, and the 128th Division was getting ready to confront the enemy advance at Lotzokou, with General Murakami’s 3rd Army holding strong in the Tumen fortified region. Meanwhile, the Nanam Divisional District Unit successfully repelled an amphibious invasion in Chongjin, and the 88th Division’s 125th Regiment staunchly defended Furuton on South Sakhalin. In a desperate bid to avoid further disaster, Yamada finally instructed Ushiroku to adhere to their original plan and prepare for a withdrawal to the Hunjen area, even if it meant leaving Japanese citizens and their cities vulnerable to the approaching Soviets. Ushiroku hesitantly agreed to the order but never got the chance to act on it.

On August 15, Marshal Vasilevsky’s offensive advanced much like the previous days, facing an enemy that continued to resist fiercely. To counter this, orders came to intensify the assault to gain control of key operational and strategic points as quickly as possible. In Marshal Malinovsky’s Transbaikal Front, General Pliyev’s cavalry-mechanized units encountered heavy opposition from the Inner Mongolian 3rd, 5th, and 7th Cavalry Divisions at Kanbao. Meanwhile, General Danilov’s 17th Army pressed toward Chihfeng but was hindered by water shortages, intense heat, and challenging sandy terrain. General Managarov’s 53rd Army began its advance toward Kailu, while General Kravchenko’s 6th Guards Tank Army continued its march along two fronts. The 7th Guards Mechanized Corps moved east toward Changchun, while both the 9th Guards Mechanized Corps and the 5th Guards Tank Corps advanced southeast toward Mukden. Notably, General Lyudnikov’s 39th Army finally captured Tepossi and Wangyemiao. 

Heavy Japanese resistance persisted in the sector of the 36th Army, notably in the Hailar Fortified Region and along the road and rail line through the Grand Khingan Mountains leading to Pokotu. The Japanese 119th Infantry Division put up a determined defense of Pokotu, successfully delaying the Soviet forces of the 2nd Rifle Corps from August 15 to 17, despite heavy rainfall. Meanwhile, in the rear of the 36th Army, the fighting in Hailar remained intense. The 86th Rifle Corps employed heavy artillery to systematically dismantle enemy strongholds in the hills to the northwest and southwest of the city. Position after position fell to relentless artillery bombardments, combined with sapper and infantry assaults. Ultimately, the Soviets extinguished the last vestiges of Japanese resistance in Hailar on August 18 when the remaining garrison of 3,827 men surrendered. Concurrently, in Marshal Meretskov’s 1st Far Eastern Front, forward detachments of General Zakhvatayev’s 35th Army secured Poli. General Beloborodov’s 1st Red Banner Army broke through the frontline of the 135th Division and initiated an assault on the last Japanese positions just outside Yehho. Meanwhile, General Krylov’s 5th Army, having successfully breached the Ssutaoling heights the previous evening, launched attacks against the 126th Division’s positions at Aiho but was ultimately repelled by the defenders. In light of these developments, Generals Kita and Shimizu decided to order a withdrawal toward Hengtaohotzu, which they executed successfully after sunset, leaving behind some units to cover the retreat.

Further south, General Chistyakov’s 25th Army split into two columns at Heitosai. The 17th Rifle Corps and the 72nd Mechanized Brigade advanced west toward the Taipingling Pass, while the 39th Rifle Corps, along with the 72nd and 257th Tank Brigades, headed southwest toward Wangching. The 17th Rifle Corps effectively breached the main defenses of the Japanese 128th Division, forcing it to retreat to second-line positions southwest of Taipingling. On the morning of August 15, enemy air activity against Army Headquarters intensified significantly. Meanwhile, the Army Commander and several staff officers set out via Pataohotzu to inspect the defenses in the Hoeryong area, where the 101st Regiment was retreating from the Chonghak sector. At noon, while at the headquarters of the 127th Division in Pataohotzu, General Murakami and his accompanying staff listened to the Emperor's broadcast announcing the termination of the war. Opinions among the officers were divided regarding the veracity of this broadcast. After a brief discussion, they decided to continue military operations as per existing instructions until they received a formal cessation order. Later that night, a formal order arrived from First Area Army Headquarters, directing that all active resistance be halted, though self-defense measures were still to be implemented if necessary. Around the same time, a report came in from the 1st Mobile Brigade indicating that their positions in the Wangching area, about 25 miles northeast of Army Headquarters at Yenchi, were under attack by a sizable Soviet tank force. In response, a counterattack force was hastily assembled, consisting of two infantry battalions from the 127th Division. They were directed to advance to Wangching along the Yenchi-Chiulungping road to confront the enemy tanks. These battalions likely included the 3rd Battalion of the 280th Regiment and the 3rd Battalion of the 281st Regiment.

Additionally, the 88th Rifle Corps took control of Hunchun and crossed the Inanho River, where they en
