At this moment, the Japanese army was facing a complete collapse on the battlefield

On the west bank of the Mulberry River, the forward command of the Chinese army

The sound of artillery in the distance was still coming, and from time to time there were groups of warplanes flying in the sky, Zhong Liwei, who was sitting in the office of the headquarters, looked up at the Chinese fighters passing by the window and the columns of smoke rising in the distance, and focused his attention on the notebook in his hand

“…… The pilots who won the title of Chinese Heroes have carried out a lot of training and education work with us, and they have passed on their combat experience to the young pilots who have come to us, and this work has not long yielded remarkable results."

“…… Our 95 fighters fought a fierce air battle with 120 Japanese planes in the skies over the Siberian lord, and many Chinese heroic pilots participated in the air battle, and they taught the Japanese pilots a hard lesson.

"On 26 August, nearly 60 Japanese planes appeared over Lake Sur in the 'Arowana' area and engaged in a fierce and brutal air battle with our fighters.

"In the air battle from August 22 to 26, the Japanese lost a total of 164 planes until September 1, and although the air battle was not as fierce as before, our pilots improved their skills and exercised their will to win through this series of air battles almost every day."

“…… It is with gratitude to the soldiers that I remember these remarkable pilots, who were excellent pilots with great flying skills and great humility, excellent leaders and instructors, and whom all the young pilots genuinely loved."

"It is no accident that the activities of the Japanese aircraft are intensifying, and it is clear from all of us, after analysis, that they are pursuing such an aim: to seriously inflict on our air forces and seize air supremacy in order to ensure the large-scale offensive campaign that their troops will be engaged in, and in order to achieve this goal, the enemy has transferred from Hailar the units originally scheduled to operate within the formation of the 6th Army, which has already begun."

"The Japanese command, which had intended to complete this offensive campaign in the first half of August, in order to conclude all military operations in Siberia before the arrival of autumn, was so sure of the victory of the Japanese that they even invited some foreign reporters and military attachés to the combat area to watch their victorious march, and among the invited guests were German and Italian reporters and military attachés."

"Before dawn on September 3, Colonel Wang Xiaolai went to Bayindagang Mountain to inspect the defense of the 6th Cavalry Division of the Northeast Army, but it was completely unexpected, he found that there were Japanese troops there who secretly crossed the Sangye River at night and were attacking the 6th Cavalry Division of the Northeast Army.

"Considering the danger of the situation, Colonel Wang Xiaolai immediately came to the command post of the army headquarters to report the situation on the Bayinda Gang Mountain, and it was obvious that in this area, the Japanese army could carry out an unhindered surprise attack on the flank and rear of our army's basic group."

"In view of the situation at that time, all our reserves, immediately after receiving the battle alert, were dispatched and ordered to advance without delay in the direction of Mount Baindagang and to attack the enemy, the 1st Tank Brigade was ordered to attack the enemy from the march, the 24th Motorized Rifle Regiment reinforced an artillery battalion, and was ordered to coordinate with the 11th Tank Brigade to attack the enemy, and the 7th Motorized Armored Brigade was ordered to attack the enemy from the south, and the armored battalion of the 8th Cavalry Division of the Northeast Army was also ordered to advance in this direction"

"In the early morning of September 3, I and the generals of the Northeast Army came to the area of Bayindagang Mountain, ordered the heavy artillery battalion of the 185th Artillery Regiment to send an observation post to Bayindagang Mountain, and shelled the Japanese group, and at the same time ordered the artillery of the 9th Brigade, which was located on the east bank of the Sangye River to support the motorized armored brigade, also to shoot at the Japanese troops on Bayindagang Mountain, and our planes all took off after receiving the battle alert."

"At 7 o'clock in the morning, our first batch of bombers and fighters flew to the Bayindagang Mountain and began to bomb and attack the enemy, and before the arrival of our counter-assault reserves, we used aviation attacks and artillery fire to pin down the enemy and stop the enemy at the Bayindagang Mountain, which is very important, and in order to prevent the enemy from continuing to cross the river and concentrate forces in the area of the Bayindagang Mountain, I ordered to intensify the bombardment and artillery bombardment of the Sangye River crossing."

"At about 9 a.m., the vanguard detachment of the 11th Tank Brigade Advance Battalion arrived in the area of Mount Bayindagang"

"Nearly 150 tanks of the heroic 11th Tank Brigade, 154 armored vehicles of the 7th Motorized Armored Brigade, and the 8th Armored Battalion of the Northeast Army equipped with 45-mm cannons were put into battle."

"Therefore, our trump card is the armored tank corps, and we decided that we would immediately use them to annihilate the Japanese troops who had just crossed the river from the march, not allowing the enemy to build fortifications and organize a defense against tanks, and a counter-assault on the enemy must not be delayed? Because, after discovering the arrival of our tank troops, the enemy quickly took defensive measures and began to bombard our tank columns, but the enemy had nowhere to hide, because the surrounding area was completely open for hundreds of miles, and there was not even a bush."

"At 9:15, we met with the commander of the 11th Tank Brigade, Major General Jiang Dengxuan, who advanced with the main force of the avant-garde battalion, commanded the actions of the battalion, analyzed the situation at that time, and decided to call all aviation, plus the movement of tanks and artillery, to launch an attack on the enemy no later than 10:45 The main force of the 11th Tank Brigade was launched, and launched an attack on the Japanese from the march"

"Here is what a Japanese soldier Nakamura wrote in his diary about the events of September 3:"

"Dozens of tanks suddenly rushed towards us, and we were panicked; The horses neighed and dragged the artillery carts around; Cars were also flying in all directions, and two planes of our army were shot down in the air, and the officers and men were all terrified, and the words that became more and more common in our mouths were: 'terrible,' 'pathetic,' 'terrified,' and 'thrilling.'"

"On September 4th, the fighting continued day and night, until 3 a.m. on the 5th, when the enemy's resistance was finally crushed, and the Japanese began to retreat to the ferry in panic, but their own sappers, fearing the breakthrough of our tanks, had blown up the ferry, and the Japanese officers jumped into the water in full armor, and our tank crews saw them drowned in the water."

"The remnants of the Japanese army that occupied the Bayindagang Mountain were all annihilated, on the eastern slope of the Bayindagang Mountain on the Sangye River, thousands of corpses, a large number of horses killed, piles of destroyed artillery, mortars, machine guns and vehicles covered the Bayindagang Mountain, and in the air battles of the past few days, the Japanese lost 145 aircraft, including 60 dive bombers"

The commander of the 23rd Division of the Japanese Army, Michitaro Komatsubara, saw that the war was not going well, and on the night of September 3, he led the combat group to retreat to the other side of the river.

"General Michitaro Komatsubara's car drove forward slowly and cautiously, the moon illuminated the plain as if it were day, the night was quiet and tense, like our group, the moonlight shone on the river, the river reflected the light of the flares dropped by the enemy, what a terrible night scene, we finally found the bridge and crossed the river smoothly, it is said that our troops are surrounded by a large number of enemy tanks, and we must be very vigilant in the danger of annihilation."

"On the morning of September 5, the battle in this area of the Bayindagang Mountain and the west bank of the Sangye River was no longer gunshot, and the battle ended with the crushing of the main Japanese group, which was a model of active defensive action of the Red Army, and after this battle, the Japanese army no longer dared to venture across the Sangye River."

"At this time, the battle on the east bank of the Samye River was still going on intensely, and the enemy, who had been routed at Mount Bayindagang, moved the remnants of his troops to the east bank of the river in an attempt to support the Yasuoka troops, who were tasked with pinning down, and this force also suffered heavy losses and did not make any progress."

"These two victories greatly boosted the morale of our army, and the officers and men of the unit sincerely and warmly congratulated us on our victory."

"The 11th Tank Brigade, the 7th Motorized Armored Brigade, the 8th Armored Battalion of the Northeast Army, and the artillery units that fought in concert with the above-mentioned units played an important role in the battle of Bayindagang Mountain, and the combat experience of the Air Force in Baindagang Mountain shows that a tank and motorized mechanized unit that is good at fighting in conjunction with the Air Force and mobile artillery is a decisive weapon for carrying out rapid combat operations with resolute objectives."

"Now the enemy is limited to combat reconnaissance operations; However, on August 12, an infantry regiment reinforced with artillery, armored vehicles and some tanks, supported by 22 bombers, attacked the 22nd Cavalry Regiment of the Northeast Army and occupied the Dasha Heights at the southern end of the front."

"The enemy actively built up defenses along the entire line: bringing in timber, digging trenches, building shelters, carrying out engineering operations to strengthen positions, etc., the enemy's air force, after suffering heavy losses, shot down 116 aircraft from September 23 to August 4, limited to reconnaissance flights and small-scale bombardment of our central crossings, artillery positions and reserves"

"The command of our troops carefully carried out preparations for a general offensive, which was expected to take place no later than August 20 and aimed at finally crushing the Japanese troops who had invaded the territory of Siberia"

"In order to carry out the general offensive, in accordance with the requirements of the Military Council of the 1st Army Group, two additional infantry divisions, one tank brigade, two artillery regiments and other units were transferred from the country to this line, and bomber aviation and fighter aviation were strengthened"

"In order to carry out this extremely complex campaign, we also had to transport a large amount of supplies from the supply depot along a 650-kilometer dirt road to the Sangye River, and it would take 3,500 trucks and 1,400 tankers to get these supplies before the campaign began, while the army group had only 2,724 trucks and 1,912 tankers until after August 14, when another 2,250 trucks and 1,375 tankers were transferred from the country, but there were still several hundred of these two vehicles."

"The main burden of transportation is borne by the cars of the troops and the vehicles of the platoon, including artillery tractors, and we have decided to take this measure of last resort because, firstly, there is no other way out, and secondly, we are convinced that the defense of our army is quite strong"

"Our warriors, the drivers of the cars, have done something practically impossible, a trip of 1,200 to 1,300 kilometers in scorching hot conditions takes five days!"

"The Mongolian Military Region has given us great help in organizing, transporting, and logistical work, and without their help, we would certainly not have been able to build up a reserve of materials, technology, and equipment needed for the campaign in a very short period of time."

"We believe that the suddenness of the tactics of the campaign is the decisive factor in determining the victory or defeat of this campaign, and we will act suddenly so that the enemy can neither resist our annihilating assault nor counterattack, and at that time we particularly noted that the Japanese army did not have good tank corps and motorized mechanized units, and could not quickly transfer troops from secondary areas and from depth to resist our assault clusters, and the actions of our assault clusters were to assault both flanks of the enemy's defensive positions in order to achieve the purpose of encircling the 6th Army"...,

"In order to conceal our actions and keep them absolutely secret, the Military Council of Army Group drew up a plan for deceiving the enemy in terms of campaign tactics while drawing up a campaign plan, which included:

- covert transport and concentration of troops transferred from within the country for the purpose of reinforcing army groups;

-- covert mobilization of troops and weapons for defense on the east bank of the Mulberry River;

-- Troops and material reserves covertly crossed the Mulberry River;

- Conduct on-site surveys of the area of departure, the area and direction of the troops' operations;

-- Increase the number of troops in this campaign to conduct special covert drills in various subjects;

-- Covertly carrying out supplementary reconnaissance by all branches of the armed forces;

-- Disseminating false information to deceive the enemy so that he cannot understand our true intentions."

"By the above-mentioned measures, we have tried to give the impression to the enemy as if we have no preparatory measures of an offensive nature, so that the enemy thinks that we are carrying out a great deal of work for the purpose of organizing the defense, and only for the purpose of organizing the defense, and in order to deceive the enemy, it has been decided that all movements, concentrations, and dispositions should be carried out only at night, because the enemy's aerial reconnaissance and visual observation are greatly limited at night."

"Until 17-18 August, it was strictly forbidden for troops to enter the area of departure and launch a surprise attack from that area, and the commanders who intended to make the troops advance to the flanks and rear of the enemy group to conduct field reconnaissance were required to wear army soldier clothing and travel only in cargo trucks"

"We knew that the enemy would conduct radio reconnaissance and eavesdrop on telephones, and in order to create false information, we had prepared a full set of radio and telephone talk plans, which involved only the establishment of defenses and the preparation of defenses for the autumn-winter campaign, and radio calls mainly used easily decipherable codes"

"We printed thousands of leaflets and a number of soldiers' defense instructions, and threw them at enemy positions so that the enemy could see what the focus of our army was"

"The concentration of our troops' flank assault clusters and their entry into the area of departure of the offensive are scheduled for the night of August 19, and before dawn on the 20th, all the troops should covertly enter the pre-constructed concealed fortifications in the trees along the coast, and the artillery, mortars, towing tools, and various technical equipment should be carefully covered with camouflage nets made of convenient equipment, and the tank units should enter the departure area in small groups from different directions before the preparation of artillery fire and aviation fire preparations, and the tank units should proceed quickly and thus allow them to do so."

"The night movements of the troops are carried out by all kinds of noisy sound planes, and the firing of artillery, mortars, machine guns and guns of all kinds covers the various noisy sounds of the units in strict accordance with the schedule drawn up in accordance with the mobilization plan."

"In order to camouflage the movement of the troops, we also used all kinds of sound equipment, which can realistically simulate the sound of piling, aircraft flight, tank movement, etc., 12 to 15 days before the assault group began to move, we began to simulate all kinds of sound, so that the enemy is accustomed to it, at first the Japanese army took this simulated sound as the sound of the real movement of the troops, so they fired at the place where the sound was generated; But then, maybe they got used to it, maybe they knew what was going on, and they stopped paying attention to any voice, and that was extremely important when we really changed our deployment and focused."

"In order to prevent the news of our offensive campaign from leaking out, in the headquarters of the army group, the commander, the chief of staff, and the chief of operations will personally draw up the plan for the general offensive, and the commander of each branch of the armed forces and the chief of logistics will draw up the relevant plans separately according to the plan approved by the commander, and only one typist will be responsible for printing the campaign plan, orders, battle orders, and other operational documents" (to be continued)
