July is like fire, Nanjing is one of China's "four major fire cities" (Nanjing, Chongqing, Wuhan, Changsha), at this time the temperature has been close to 40 degrees Celsius, rain and heat at the same time, accompanied by high temperature, is quite abundant rainfall, which is about to start the Nanjing Campaign, both China and Japan are uncomfortable.

Summer rain is often accompanied by thunder and lightning, and as long as there is thunder, planes cannot take off and cannot deliver air strikes on areas covered by thunder. To tell the truth, although the Chinese Air Force has a certain advantage in the performance of fighter aircraft, it is subject to the current situation of the general low cultural quality of the whole people and the low degree of industrialization, and the combat effectiveness of the Air Force is irretrievably declining by a large margin. A few months ago, the Air Force had a total of more than 600 fighters on duty, and on the battlefield at that time, the combined air force of the Japanese Army and Navy could not take advantage of anything, but now they have an increasingly large advantage, and the air supremacy of the Chinese army in East and North China is gradually being lost.

Therefore, the thunderstorm makes it impossible for all the planes to be dispatched, which is more advantageous for the Chinese army. In the Battle of Songhu, the Air Force's QL-2 Stuka bombers had a high sortie rate, both in terms of combat results and losses, and the bomber pilots who survived the battle could almost be called trump cards. After learning that Liu Cuigang and Le Yiqin crashed, in order to keep more pilots, Dongfang Yunming ordered all QL-2s of the East China Air Force to be transferred back to the Air Force Aviation University as advanced training aircraft, and all the dive bomber pilots who participated in the Battle of Songhu became instructors of the aviation school, and then the Air Force General Headquarters issued an order: All ace fighter pilots who flew more than 1,500 hours or shot down more than 6 enemy planes were all transferred from the front line, or served as instructors at the Air Force Aviation University. Either go to a middle and high military school for further training and become a commander of an aviation unit.

Since 1934, when Dongfang Yunming single-handedly established the Air Force, it has been facing the problems of scarcity of excellent pilots, insufficient aircraft research and development strength, and low industrial production capacity. In order to allow the air force to play its greatest role in the shortest possible time, Dongfang Yunming decided to give priority to the development of fighter and transport planes, and to postpone the development of bombers and attack planes.

So far, in the ground attack force of the Chinese Air Force, there are only more than 120 medium bombers left in the 32 aviation division of the 3-4-3 formation of medium bombers QL-3 (3 in 1 squadron, 3 squadrons under the jurisdiction of one brigade, a total of 10 commanders in the increased brigade, 4 brigades in one regiment, and 3 regiments in the 32 aviation division), and there was no further replenishment after the battle damage, with less than 150 QL-2 bombers left, and 66 BH-2 fighter aircraft were produced and then discontinued. Contrary to bombers and attack aircraft, the size of the transport aircraft force of the Air Force has also developed to more than 600 units in 5 aviation divisions, the earliest 24 Ju-52 have been refitted, and now they have become the advanced trainer aircraft of the Aviation University, with a load of about 4 tons of XW-1 series There are 84 aircraft, most of which are used as experimental platforms by the Academy of Defense Sciences and flight design institutes, the number of XW-2 series with a load capacity of 8 tons is not much, about 40 aircraft, as the absolute main force of transport aircraft is the XW-3 series, with a load capacity of 15 tons, Mass-produced by Airbus in 1936, it is a standard military transport aircraft with a single-wing configuration, a rather stout landing gear and four high-power air-cooled engines that allow it to take off and land on non-hard runways at front-line airfields. Because it is a transport aircraft, the Western powers have very loose control over its import and export trade, and 400 of the 600 Xuanwu-3 transport planes of the Air Force are produced and assembled in North America.

A huge fleet of transport planes traveled between southwest and east China, bringing many urgently needed supplies from Chengdu, Chongqing and other places to the front. The Japanese army attacking Nanjing also understood this situation, but there was no way to intercept it, the Chinese XW-3 has advanced radio navigation equipment, Nanjing's airport not only has a radio navigation base station, but also creatively uses the Fresnel lens principle to engage in an "optical landing system", transport aircraft pilots do not need to pay attention to the runway when landing at night, only need to stare at the lens, ensure that all they see is green light to ensure that they can land properly and accurately on the runway, After all, this thing can guide jet carrier-based aircraft to accurately land on aircraft carriers in later generations.

……

The 158th Division of the 78th Army met the 13th Division of the Japanese Chinese Dispatch Army in the Changshu area, and the enemies were very angry when they met.

Because of the continuous rainfall, this area has long been muddy, Yang Hanyu was quite prescient, the 78th Army left the artillery brigade in Nanjing before the dispatch, only carrying mortars as artillery support, he judged, with the marching speed of the 13th Division, they even want to bring 75mm field artillery, the 78th Army faced the enemy's largest caliber artillery is the 94 type 75mm mountain artillery, whether it is range or shell power, the 94 type mountain artillery is not as good as China's PP-34A 120mm heavy mortar.

The 13th Brigade of the 58th Wing of the Vanguard of the 13th Division launched seven attacks on the troops of the 3rd Battalion of the 591st Regiment of the 158th Division, the forward of the 78th Army, but was never able to overcome the temporary position of this battalion. The Japanese attack was actually quite rigid, first the artillery bombardment, then the artillery fire was extended, and finally the infantry charged, the standard was like a textbook, at most the infantry attacked with a few tanks or armored vehicles.

Attacking the position of the Southwest Army, the Japanese army always felt awkward, and the sense of rhythm of attacking the Central Army could not be found here at all, when the offensive began, the infantry was still assembling, and the Type 92 infantry guns and 81mm mortars to which the brigade belonged opened fire to bombard the positions of the Chinese army, and in less than 3 minutes, the 60mm mortar shells from the anticline of the opposite position fell into the Japanese artillery positions, and the small-caliber mortar shells were not enough to destroy the structure of the Type 92 infantry guns, However, the Japanese artillery suffered heavy casualties from the shrapnel flying everywhere. The artillery coverage was forced to be interrupted, let alone extended, and the little devils had to disperse the artillery and arrange it, but in this way, the artillery fire lost its unified command, and each gun needed to independently calculate its own firing parameters, which was quite large, and the supply of shells was also very troublesome, and it was impossible to form a firepower advantage over the Chinese army.

After about ten minutes of artillery fighting between the two sides, there was really no way, and the devil's infantry began to charge, still feeling that the rhythm was not right. With the quality of personnel and weapons of the 78 th Army, the entire 591 Regiment has 450 people in the three battalions, the width of the defense surface is nearly two kilometers, and the depth is 800 meters. Therefore, even if the Japanese army shelled normally, with such a sparse distribution of soldiers, the lethality of artillery fire was very limited.

However, the sparse personnel does not mean that the firepower is also weak, the devil infantry began to charge a few steps, the opposite position of the depth of the more than a dozen M2 heavy machine guns began to shoot a single shot, this is a 12.7mm heavy machine gun, was hit by its bullets, that is really called a dead body, at this distance, the Japanese army's Type 92 heavy machine guns can not play a firepower, not to mention that from time to time there are one or two mortar shells to hit over. Desperately fighting for huge casualties, the vanguard of the Japanese army couldn't gnaw at this hard bone in front of them at all. The last time, after repelling the attack of the devils, a battalion of the defending Chinese army also drew a company from the reserve behind the position, followed the footsteps of the devils to counterattack, and at the same time the mortar fire extended to the rear of the Japanese army, almost reaching the brigade headquarters, if it were not for the three major teams of the 58th Wing to arrive in time for reinforcements, the front of this large group of devils may have collapsed.

The 78th Army and the 13th Division continued to increase troops here, the 78th Army was originally a battalion here, 3 hours later another battalion came, 8 hours later the strength increased to two regiments, 24 hours later, the entire 158th Division appeared in Changshu, appeared on the battlefield, the 13th Division of the devil also spared no effort to increase troops, 58 Wing, 104 Wing, 116 Wing in place. Unable to break through the front, the Ogizhou troops could only sacrifice the most usual detour tactics used by the Japanese army, and sent the 65th Wing to make a detour from the junction of Changshu and Xinzhuang in the south, preparing to outflank the 158th Division from the rear.

In addition, the Ogizhou soldiers constantly urged the division and regiment heavy artillery wing that fell into the mud on the march to speed up, this thunder and lightning ghost weather, the aviation could not be dispatched, the only heavy firepower that the Ogizhou soldiers could count on was the 105mm 91-type field artillery of the heavy artillery wing, without bombers and artillery, the Ogizhou soldiers did not know how to quickly tear apart the defense line of the Chinese army, but what he knew was that if the 78th Army of the national army was blocked in the Wuxi-Changshu area and could not make a breakthrough, the 13th division and the naval fleet cooperated to attack JiangyinThe coastal defense heavy artillery in the Jiangyin fortress will pose a huge threat to the light cruisers and destroyers of the Japanese navy sent by China, and if Jiangyin cannot be taken, the navy will not be able to support the operation against Nanjing.

The 65th Wing, which was tasked with a roundabout outflanking mission, had just crossed Xinzhuang and ran into Liu Yuanxuan's 161st Division head-on. Yang Hanyu had long expected that the frontal battle was unfavorable, the Japanese army would definitely have to detour from the side, the north was the Yangtze River, then it must only go to the south, with the combat power of the 158th Division, there was no problem in withstanding the attack of the 3 infantry wings of the 13th Devil Division head-on, so vacate a 161st Division, Yang Hanyu's idea was that since the number of troops is 10,000 more than your Ogizhou troops, then I will return the favor to the other side in the other way, and I will also outflank him from the side, not only eating your troops to my rear, but also cutting off the logistics supply line of your 13th Division, Trapped you in Changshu, anyway, it was you who were in a hurry to attack, not me, Yang Hanyu.

An infantry wing encountered a motorized infantry division, and the result was predictable, as the 161st Division surrounded and annihilated the 65th Wing in two days, and then continued its march to the enemy's rear. Ogisu immediately sent a telegram to the headquarters of the Chinese Dispatch Army asking for help, and in the face of the encirclement of more than 30,000 people of the entire army of the Southwest Army, he was not sure that he could break through without foreign aid.

The closest to the 13th Division was Fujita's 3rd Division, which was also part of Okamura Ninji's 11th Army, but he could not fully rescue the 13th Division, because at this time, Wang Jingjiu's 87th Division and Sun Yuanliang's 88th Division launched an attack on Suzhou at the same time.

Sun Yuanliang is a good hand at fighting the kind of high-flying battle, and he is quite brave (but whenever the above is ready to retreat, he is the first to run, and the troops can be left alone), although the 87th and 88th divisions suffered heavy losses on the Songhu battlefield, but after all, they are the foundation of the German armament division, and they are still quite effective after replenishing the equipment and reorganizing into the 71st Army. Wang Jingjiu concentrated all the artillery of the whole army and launched a fierce attack on the city of Suzhou, forcing Fujita to leave at least one wing to meet in the city, and one wing and the divisional field artillery wing had not yet arrived in Suzhou, and only two wings could be drawn out to support the 13th Division.

In order to open up Jiangyin as soon as possible, Okamura Ninji ordered Yoshizumi Ryosuke's 9th Division, Yamamuro Sotake's 11th Division, and Ito Masaki's 101st Division to rush to the aid of the 13th Division and the 3rd Division, and unite the forces of 4 Division A and 1 Division C to defeat the Chinese 78th Army and 71st Army in front of them. In addition, the Chinese Dispatch Army Command also ordered Yanagawa Heisuke's 10th Army (under the jurisdiction of the 6th, 18th, and 114th Divisions and the Guoqi Detachment) to seize the time to advance to Nanjing from the south, and the 105th, 107th, 110th, and 114th Divisions to attack from the north and blockade the Yangtze River.

In charge of the defense of the south of Nanjing was Xu Yuanquan's 2nd Army, Yu Jishi's 74th Army, He Zhizhong's 103rd Division and Huo Shouyi's 112th Division, behind them was Gui Yongqing's Central Military Academy Teaching Corps, in the rear of the 71st Army and the 78th Army was covering and supporting Ye Zhao's 66th Army, and there were also 4 military police regiments of Xiao Shanling in Nanjing who were responsible for evacuating the people and consolidating the city defense. The East China Theater Command ordered that every street and house in Nanjing be turned into a firepower point in preparation for the final street battle with the Japanese army.

In the areas occupied by the Japanese army, fighting also broke out at every moment, and guerrillas of the New Fourth Army sprung up like mushrooms after a rain in Kunshan, Wuzhong, Taihu Lake, Jiaxing, and other places; for a time, almost all the roads leading from Shanghai to Nanjing were attacked by guerrillas, and even a large number of guerrillas appeared on Taihu Lake, and the equipment and materials transported by the Japanese army to the front line suffered serious losses. The Japanese army has always paid little attention to logistics, so in less than half a month, the 10th Army, the 11th Army and several other divisions and brigades on the front line have begun to run out of ammunition, the 11th Army is okay, relying on the Yangtze River, can accept supplies from the water, the positions of the 71st and 78th armies are slowly retreating, but the situation of the 10th Army is very bad.

When Lieutenant General Yanagawa Heisuke arrived in Huyang, he received a report that the heavy artillery brigade assigned to the 10th Army by the Dispatch Army Headquarters had been attacked in Huzhou, and almost all the Type 96 150mm heavy cannons and tractors were destroyed after being planted with explosives, and almost all the combat personnel of the heavy artillery brigade were wiped out, and most of them did not die from shooting, but cyanide poisoning!

Obviously, this is no longer something that the guerrillas of the New Fourth Army can do, and this is the masterpiece of the wolf's teeth. Upon learning that the only heavy artillery brigade of the Dispatch Army had been destroyed, Okamura Ninji once again remembered the mysterious unit that had been wandering around the four eastern provinces for a month five years ago, they attacked the castle of Chuma, attacked many airports of the Kwantung Army, hijacked bombers and bombed the puppet Manchurian palace, robbed more than a dozen Japanese banks, swept away more than a dozen tons of gold and silver, and finally even provoked a conflict between the Soviet Union and the Kwantung Army (although there was no evidence and clues, Okamura Ninji's intuition told him that it must have been the incident provoked by the small army called "Wolf Fang").

What happened was that Xu Erhang received a notice from the East China Theater Command, so he sent the second and third squadrons under the Langya Special Brigade and the three special commandos of Baihong, Phantom, and Thunderbolt (this Thunderbolt is not the same team as the original Thunderbolt) to parachute and infiltrate behind enemy lines, attack the Japanese army's logistics units together with the New Fourth Army, and wait for an opportunity to behead the Japanese army's headquarters at and above the brigade level.

When the heavy artillery wing entered Huzhou, it was discovered by the Taihu guerrillas of the New Fourth Army (it is impossible for such a big cannon not to be discovered), this important situation was immediately reported to the military headquarters of the New Fourth Army, and the commander Ye Ting directly informed Tan Xiaolin, the commander of the theater, that the threat of the heavy artillery brigade to Nanjing City is quite large, Tan Xiaolin immediately telegraphed to the thunderbolt commando closest to Huzhou, and found a way to eliminate the heavy artillery brigade, because the QL-2 dive bombers have all been transferred back to Chongqing, and the QL-3 bombers are fighting with the Zhongshan aircraft carrier strike fleet in Guangzhou, The elimination of heavy artillery brigades could only rely on special forces and guerrillas of the New Fourth Army behind enemy lines.

The strength of the thunderbolt commando alone is obviously not enough, the Phantom and Baihong two commandos also quickly came to Huzhou after getting the news, and the Taihu guerrillas of the New Fourth Army also got in touch with the wolf's teeth, and found through a day's reconnaissance that the entire brigade of more than 4,000 people were all stationed together, including a garrison wing of 1,500 people and a baggage wing of 1,500 people, a total of 36 150mm heavy cannons and the same number of special tractors, all artillery was on the march, and the ammunition was carried by vehicles. The food supply of the heavy artillery brigade was separate, and in response to this, Lieutenant Colonel Huang Zhifei, the leader of the Baihong commando, decided to kill the guards of the heavy artillery brigade by poisoning and destroying the heavy artillery with explosives.

The night before the operation, an XW-3 transport plane dropped 100kg of C4 plastic explosives and more than 50 pieces to them. At half past five o'clock in the afternoon, the little devils of the guard wing enjoyed a sumptuous dinner without noticing, and at about 7 o'clock in the evening, the time was almost up, and the Baihong commando team infiltrated the station of the heavy artillery brigade, and after the devils standing guard and patrolling inside were indeed poisoned and died, they sent a signal to notify the large troops on the periphery.

Half of the fighters of the Taihu guerrillas helped to place each shell weighing more than 50 kilograms from the ammunition box under the artillery, and then entered the barracks to clean up the little devils who were not yet dead, and the special forces put the prepared C4 explosives on the shells, connected to signal receivers and electric detonators.

20 minutes later, everything was ready, everyone withdrew from the station of the heavy artillery brigade, Huang Zhifei took out a square box about the size of a brick, pulled out the antenna, pressed the red button in the middle of the box, all the C4 explosives exploded at the same time, the detonation wave detonated the charge of the large-caliber shell, and the explosives equivalent to dozens of kilograms of TNT under each cannon exploded, and all the Type 96 cannons were blown into parts.
