A month after the Battle of Songhu, the Nationalist Air Force suffered all losses, and the Japanese army's air superiority prevailed. Japanese fighters not only effectively supported offensive operations, but also bombed the Nationalist army's transportation lines indiscriminately, and the Yangtze River transportation line from Nanjing to Songhu was hit like never before. The logistical supply of the troops in the theater of operations became a big problem. The water transport line was effectively contained by the Japanese Air Force, and the road transport line became the focus. In order to meet the needs of the battlefield, Jiangxi alone dispatched 15 transport teams and continuously transported military supplies to the war zone.

At this time, the center of gravity of the battlefield was still located in Luodian in the northwest, and the core of the 15th Army's defense was also Luodian. The 11th Division of the Japanese Army launched a fierce offensive against Luodian, and the 67th Division defending Luodian suffered more than half of the casualties in the bloody battle on the 5th, and the 201st Brigade was almost completely lost, and the brigade commander Cai Bingyan was killed. The strategic value of Luodian is very important, and here it is to ensure the absolute security of the entire theater of operations. The purpose of the Japanese army was to take Luodian and encircle the main force of the national army, so the two sides fought fiercely around Luodian.

The 67th Division was no longer able to fight, and Chen Cheng ordered the 108th Division of the 67th Army of the Northwest Army to go into battle. The 67th Army of the Northwest Group Army was Zhang Xueliang's elite, and Wang Yizhe, commander of the 67th Army, received Zhang Xueliang's order and immediately led the 107th, 108th, 117th, and 129th divisions of his headquarters to the Songhu battlefield. Due to the convenience of the Longhai railway line, the 67th Army was the first "miscellaneous force" to rush to the Songhu Theater in addition to the Central Army. After arriving at the theater, the four divisions were immediately assigned to the 15th Group Army and put into the northwestern part of the Songhu theater for operations.

The 108th Division took over the defense of the 67th Division at Luodian and quickly stabilized the Luodian position. The Japanese 11th Division suffered heavy casualties in continuous hard fighting, and Matsui Ishine quickly withdrew the 11th Division according to the battle situation and ordered the 38th Field Division of the Kwantung Army that arrived on the battlefield to go into battle. Due to the changes in the general environment in the northwest, the Northwest Group Army has sufficient soldiers, excellent weapons and equipment, and the combat effectiveness of its soldiers is significantly higher than that of the 67th Division, but it is still difficult to withstand the fierce 38th Division of the Kwantung Army. In the land of Luodian, the battle was even more tragic.

The battle on the battlefield was thick, and in the headquarters of the 67th Army, Army Commander Wang Yizhe put down the phone and said with a majestic expression: "Commander Chen, strictly order us to take back the positions we lost during the day and take advantage of the darkness to recapture." The 108th Division was ordered to recapture positions No. 7, 15, 19, and 25 lost during the day at any cost. Due to the special relationship between the Northwest Group Army and the Shaanxi-Gansu-Ningbo Border Region, it can be said that the Northwest Army was the first to get closer to the water, so it purchased a lot of "advanced" weapons from the Eighth Route Army.

During the day, the heavy artillery of the Japanese army was strong, and the fierceness of the Kwantung Army made it inevitable that the position would change hands. After dark, the Japanese army stopped attacking, but the Japanese army continued to shell non-stop, and the battlefield was not quiet. In front of position No. 7 in Luodian, a company of commandos was in position. In the dark, the soldiers each had a submachine gun, which was a company of the independent regiment of the 108th Division, all hunting submachine guns. The gun is a submachine gun developed in Jiujiang, Jiangxi, this submachine gun has a simple structure and easy operation, especially the price is very cheap.

The gun was named the anti-Japanese submachine gun and went into production in the middle of 36. The disadvantage of this submachine gun is that it is not very accurate, but the density of fire hits makes up for this shortcoming. Another disadvantage of the gun is that the demand for ammunition is too great, so Zhang Xueliang only equipped 4 regiments with the 67th Army, which was under his command. In addition, before the 67th Army set out for the expedition, the Shaanxi-Gansu-Ningbo Border Region provided 100 flying thunder cannons (unconscionable artillery) and 5,000 flying mines. The Flying Thunder Cannon, also known as the Conscienceless Cannon, uses a cylinder to launch a bag of explosives shaped like a disc in the form of a projectile.

A few words of verbose, the unconscionable cannon is the product of the liberation war in later generations. At that time, during the Huaihai Campaign, the number of artillery pieces of the People's Liberation Army was very small, but in the face of brutal offensive operations, the 4th Column of the Jinlu-Henan Field Army invented this artillery. At the beginning, the conditions were poor, and only gasoline barrels could be used as barrels to transport "flying thunder" explosive packets, and the range of flying thunder could reach 150 to 200 meters. For the unconscionable cannon,. Ouyang Jian is naturally familiar with it, and in order to deal with the Japanese army, he ordered the Weapons Research Institute to develop a flying thunder cannon in early 36.

Due to the fact that the Flying Thunder Powder used TNT explosives, the explosion was violent. Therefore, the flying thunder cannon developed by Jiujiang has a barrel half smaller than that of a gasoline barrel, with better sealing performance and greater explosive power. Due to the good sealing performance and the standardized performance of the propellant, the firing range of the flying thunder cannon can reach 300 meters. To get back to the point, the Japanese troops in position 7 discovered the counterattack force, and suddenly the Japanese heavy machine guns began to form a crossfire blockade, and the soldiers scattered their lines to attack, attracting the attention of the Japanese army.

At this time, a pair of figures carrying flying thunder barrels and "explosive packs" on their shoulders quietly approached the No. 7 position. If the target of the flying thunder artillery was too large during the day, it was impossible to approach the Japanese position, and the dark night played a good role in covering. Position No. 7 was defended by about two squadrons of Japanese troops, and the attacking force followed the attack in addition to a submachine gun company and an infantry company. At this time, the Japanese support artillery fire was overwhelming, and the counterattacking troops were suppressed.

At this time, 10 flying thunder cannons fired a salvo, and 10 flying mines flew towards the Japanese defensive position. It can be said that the power of the explosion was like the heavy artillery fired by the Japanese army, and the Japanese defensive positions were shrouded in deafening explosion fire. At a Japanese heavy machine gun position, a thunder shell fell 10 meters on the side and exploded, and the air wave of the explosion quickly overturned the Japanese machine gunners and heavy machine guns. It was the first time that the Japanese soldiers had been hit by such a blow and began to hide in all directions. However, when the second round of flying thunder came, the Japanese soldiers couldn't stand it anymore. He actually jumped out of the trench and launched a counter-charge below.

The Japanese defenders were ready to use white-knuckle combat to counter the attack of the Nationalist army. However, the Japanese soldiers did not expect that it was the submachine gun company that rushed to the front. With the heavy rain of bullets, the Japanese soldiers could not get close at all and were knocked to the ground by the dense rain of bullets. Seeing this, the Japanese commander immediately ordered a retreat. Two squadrons of Japanese troops were reimbursed by at least one squadron, and position No. 7 was successfully recaptured. Why are the Japanese soldiers known as devils, as long as they do not fall into a desperate situation, they will not use desperate tactics.

However, this time it was different, and overnight the 4-made position was not only successfully recaptured by the national army, but also lost 3 squadrons of soldiers. For the Japanese army, fighting the national army had never paid such a heavy price. During the daytime the next day, the Japanese intensified their artillery attacks and launched a retaliatory assault, in which the infantry companies defending the four positions suffered heavy casualties and the positions changed hands again. At night, the four positions were recaptured by the 108th Division again, and the Japanese army had no good way to deal with it for a while.

However, in the face of the Japanese long-range heavy artillery, the battle loss rate of the 108th Division far exceeded that of the Japanese army. However, the Japanese army also continued to pay the price of casualties, and the morale of the soldiers of the national army was greatly boosted. Therefore, the tragic battle of Luodian has become dramatic, the day is the world of the Japanese army, and the night has become a one-man show of the national army, so the use of night to launch a battle has become the national army's specialty. In particular, submachine guns and flying thunder cannons showed their might and became a nightmare for the Japanese army.

After five days of bloody fighting, the 108th Division suffered heavy casualties, and two-thirds of the guards regiments of its division headquarters hunting submachine guns suffered losses. Army commander Wang Yizhe was forced to withdraw the 108th Division and ordered the 117th Division to go into battle. Eight days later, the 38th Division of the Kwantung Army, which was formidable, also paid a heavy price and was forced to withdraw from the battle, and the 52nd Division of the Kwantung Army was immediately put into battle. The 67th Army became the main force defending Luodian, and the battle line was stabilized in Luodian, but the bloody fighting scene continued, and the purpose of the two sides began to change, intending to kill and injure the opponent's living forces.

The Japanese Marine Corps Command in Songhu became the Command of the East Japan Dispatch Army at this time. At this time, the commander of the headquarters, Matsui Ishone, had a grim face, although the Japanese army provoked a full-scale war of aggression against China, but the uncertainty of the war still made the powerful Japanese army cautious. It has been more than a month since the start of the Songhu War, but the national army actually concentrated millions of troops to fight a decisive battle in the land of Songhu, and this kind of courage made the Japanese army change its strategy at the same time, and had to go all out to fight.

In particular, the national army was able to resist stubbornly on the Songhu battlefield for more than a month, and the battle situation entered a state of anxiety, not to mention that the commander Matsui Shigen could not have imagined, and the Japanese army base camp, including the Japanese government, did not expect it. The protracted war caused an uproar in Japan, so Matsui Ishone, as the supreme commander of the Songhu Theater, was under tremendous pressure. Just as Ouyang Jian expected, due to the butterfly effect, the Japanese army completely abandoned the northward battle plan and secretly signed a bilateral agreement with Soviet Russia: the two sides were in the border area, each reducing its troops to avoid causing a military conflict.

At this time, the strategic center of gravity of Soviet Russia was in Europe, and in order to abide by the agreement, Soviet Russia quickly seized the Chinese anti-Japanese armed forces in Soviet Russia in accordance with the Japanese demands. Under such circumstances, the base camp of the Japanese army calmly requisitioned and transferred the Kwantung Army to fight in the south. In addition, the Japanese army did not send troops from North China to requisition troops because of the changes in western China. At present, the western part of China has undergone significant changes due to the railway line leading to Lanzhou.

The Japanese know very well what the railway line means, and the railway line continues to extend westward. A major railway artery has emerged in the west, especially the huge natural salt lake in Qinghai, which is naturally coveted by the Japanese. Therefore, the Japanese army must ensure a strong westward assault force, and must occupy the strategic points of Shaanxi and Shanxi in the northwest, and then control the entire northwest, including Xinjiang. With such an attractive strategy, how could the Japanese army give up. However, China is too big, and the big one makes the Japanese depressed. Therefore, the Japanese clamored for the destruction of China in three months, in order to get the Nationalist Government to surrender.

However, in the small Songhu area, the Nationalist Government actually concentrated the most elite troops to carry out a decisive battle, which greatly surprised the Japanese base camp. However, the Japanese army also secretly rejoiced that if the main force of the Chinese army was eliminated in the Songhu area, the war in China would end in half a year at the earliest. However, a month has passed since the tragic battle, and the powerful Japanese troops have actually been blocked in the land of Songhu projectiles, which makes the commander Matsui Ishine very unhappy. And Luodian's battle made him depressed.

"Your Excellency, the Chinese army has a new weapon, a grenade (in fact, a rocket), a short-range parabolic artillery with great power. These two weapons provide combat power for enemy defense and offense. At present, the key points of Luodian have formed a state of anxiety as the enemy's follow-up troops have arrived one after another. "An operational staff officer analyzes the battle situation. Matsui Ishine hesitated for a moment and said decisively: "Order the chariot troops to attack in the direction of the big field, and be sure to occupy the strategic points of the big field as soon as possible." ”
