It's just that compared to the current tranquility of the Jizhong battlefield, in the Tianjin battlefield in the north of the entire Jizhong, the current war is in a bitter battle. Previously, Tao Jingfei took into account the characteristics of the Tianjin urban area that was wide from north to south and narrow from east to west, and adopted the attack tactics of advancing from east to west, seizing the bridge over the Haihe River, and dividing the Japanese army into two parts, north and south.

After breaking through the outer defense line of Tianjin, clearing out various Japanese strongholds on the periphery of Tianjin, such as Yangliuqing and Junliangcheng, and successively seizing a series of key points such as Haiguang Temple, West Railway Station, Ditou, and Beiyang University. Tao Jingfei concentrated the strength of four divisions, and with the cooperation of the two tank regiments, they attacked from the West Station and Haiguang Temple in the west of the city, and the Dagong Seventh Factory and the Nitrate Leather Factory in the east of the city.

Adopting the tactics of attacking from east to west, they launched an attack on the Tianjin urban area, and the confluence point of the two divisions was chosen at the Jintang Bridge and the Wanguo Bridge in the Tianjin urban area. At the same time, with the strength of one division, a brigade of the Shanxi-Chahar-Hebei Military Region and two independent regiments of the Bohai Military Region attacked northward from both sides of the lower reaches of the Haihe River, aiming directly at the British and French concessions.

According to Tao Jingfei's assumption, he attacked from the east and west, and at the same time launched an attack from the south to the north with a part of his troops, which could effectively disperse the forces of the Japanese defense. At the same time, in terms of troops, he has a one-to-two advantage. As long as the line between Jintang Bridge and Jingang Bridge is taken, and the Japanese defense forces in Tianjin are cut off, it will not be a problem to take Tianjin in a short time.

But after three days of fierce fighting, the result was completely different from what Tao Jingfei originally envisioned. In the face of the stubborn resistance of the Japanese army, as well as orders from superiors not to use heavy weapons. After three days of fierce fighting, the attacking forces were unable to complete the division of the main force of the Japanese army in Tianjin, except for a part of the attacking force that seized the Italian concession and cut off the Japanese army that was holding on to the former British and French concession and the Japanese army in other parts of the city.

In particular, the Jintang Bridge, Wanguo Bridge and Jingang Bridge, the three most important bridges on the Haihe River in Tianjin City, have been contested many times. The blockade by the heavy artillery fire of the Japanese naval ships and the stubborn resistance of the surrounding defenders were all defeated at any cost. In other words, Tao Jingfei's offensive was thwarted on all fronts after penetrating deep into the inner city.

A regiment that launched an attack on the Jintang Bridge and the front line of the Zizhulin port area was repeatedly attacked by several Japanese light ships and a gunboat on the Haihe River. Especially on the front line of Jintang Bridge, because the Japanese artillery fire was unusually fierce, causing considerable casualties.

Although the two main attack battalions of the regiment, despite the Japanese artillery interception and the extremely ferocious counterattack, at the cost of two-thirds of the casualties, after repeated battles, they captured a series of important targets such as the Fujian-Guangdong Guild Hall, as well as the Tianjin County Government and the Zhangjia Compound. Forcefully pushed the attack line to the Drum Tower line, which was not far from the target Jintang Bridge. But in the end, due to heavy casualties, he lost the ability to continue attacking.

The troops attacking the first line of Jintang Bridge suffered heavy casualties and could only turn to the defense on the front line of the Drum Tower. Although the troops at the Jingang Bridge upstream of the Jintang Bridge successively captured the two bridges of Jinhua Huaqiao and Jinzhong Bridge, the attack on the Jingang Bridge also progressed unusually slowly. After several hard battles, they were unable to make a breakthrough, and they reached a stalemate with the Japanese army on the front line of the engineering college and the bar association.

The attacking forces on the Eastern Front were also in a stalemate with the Japanese east of the Bac Ninh Railway. Although the old dragon head station was captured, the attack on the Wanguo Bridge was also frustrated many times. The troops from all walks of life were in a state of tug-of-war with the Japanese army in the large and small alleys along the Bac Ninh Railway.

The Japanese troops in the Tianjin battlefield, although they lost considerable strength on the periphery. In addition to the part of the Japanese army that was holding on to Tanggu, there were only two wings of the 27th Division and Regiment that were used to hold the inner city, plus the 15th Brigade and Regiment that were independently mixed into the 15th Brigade and other miscellaneous troops, and the total strength was only more than 30,000 people.

Even with the more than 3,000 armed expatriates urgently mobilized, as well as some puppet troops and puppet police, the total strength is less than 40,000. This is compared to the six divisions and two brigades invested by the Anti-Japanese Alliance, as well as the two independent regiments of the Bohai Naval Region operating south of Tianjin. In terms of troop strength, only half of the troops invested by the Anti-Japanese Union are invested.

However, after the Anti-Japanese Federation entered the urban area to attack fortified operations, the regulations restricting the use of heavy firepower made the front-line attack troops very different from the Japanese army in terms of firepower. In particular, the Japanese army could also receive fire support from Japanese naval ships stationed downstream of the Jintang Bridge and in the Zizhulin port area, and the difference in firepower between the two sides was even greater.

Even after the Anti-Japanese Federation broke into the inner city, it invested more than 100 tanks in two regiments. However, the large and small alleys in Tianjin also restricted the use of tanks. The tank troops could only charge along the main street, and the Japanese army used the houses on both sides of the street to set up anti-tank preset positions, which brought considerable losses to the tank troops of the Anti-United Nations.

After three days of hard fighting, except for the Jinhua Bridge and the Admiralty Bridge, which are not of great practical strategic significance. The Haihe River, which is truly strategically important and divides the main urban area of Tianjin into east and west, and the large and small bridges on the river section below the Zeng Gong Ancestral Hall, have only been captured.

Somewhat ironically, however, the bridge was built after the Japanese occupation of Tianjin, and was built as a wooden bridge connecting the former Japanese Concession with Hebei. Privately, the people call it Shimbashi, but the official name of this wooden bridge is Nihonbashi.

It's just that this bridge, which is mainly made of wood, was burned down by the Japanese naval ships at the Zizhulin Wharf downstream with incendiary bombs fired by naval guns within a short period of time after it was captured. Not only did it fail to play the role that Tao Jing did not expect, but on the contrary, it caused the Hedong troops to cross the river and attack a battalion in the former Japanese concession of Tianjin, which was re-blocked because of the open breakthrough and was cut off from Hedong.

In order to prevent the Anti-Japanese Union from using the frozen section of the Haihe River to cross the river, and to facilitate the activities of its own ships. Before the battle began, a large number of explosives were planted on the surface of the Haihe River in Tianjin. After the anti-union attack was launched, all the frozen river surfaces were blown up from the river below the Zeng Gong Temple to the Yufeng Yarn Factory.

After the only bridge was destroyed, the ice floes on the river were blown up, and the ice could not be used to cross the river. The troops who launched an attack from Haiguang Temple to the Japanese concession in Tianjin were blocked by the Japanese army and could not get close to the former Japanese consulate and the East Asian Hospital. The battalion, which crossed the river east of the river, fell into a situation of isolation and helplessness.

At present, the offensive and defensive battle of Tianjin has fallen into such a bitter battle, in addition to the Japanese artillery in Tianjin City opening fire with all their strength to intercept it, it is the few ships deployed in the section of the river below the Haihe Zeng Gong Ancestral Hall. With its own mobility and the coordination of a large number of naval guns and ground artillery, it inflicted huge casualties on the anti-United Nations attack forces.

Although these naval ships are mainly light ships, the oldest gunboat with the largest tonnage has a full load displacement of only more than 1,000 tons. But the caliber of the main guns is not small. Most ships of more than 100 tons are equipped with high-level dual-purpose guns of 120 mm caliber.

On the battlefield, with the cooperation of two icebreakers, these ships continued to move up and down quickly along the surface of the Haihe River, which had been blown up. The naval guns have a large caliber and a long range, and their power far exceeds those of the ground artillery. Almost every ship is equivalent to a mobile artillery battery.

And even if it is a small-caliber naval gun, although it is not very powerful. But there is a considerable advantage, and that is the fast rate of fire. At the same time, in the case of a comparable caliber, the firing range of naval guns is much longer than that of ground guns. The power of artillery shells is generally greater than that of artillery of the same caliber on the ground.

The main reason for the failure of the attack on these strategic-level bridges was that these warships were desperately firing to support the Japanese defenders in the middle of the battle. The explosion points of its shells were accurate and ruthless, and a dense wall of fire was created along the path of the attacking troops. The interspersed troops of the Anti-Japanese Federation caused extremely heavy casualties.

Although the anti-coalition air force that participated in the battle, the two squadrons of attack planes transferred from the Tanggu battlefield braved the anti-aircraft fire of the Japanese ships and the surrounding area to adopt the tactics of low-altitude surprise attacks, blowing up and sinking some Japanese ships, and weakening the threat of Japanese naval guns to a certain extent.

However, the remaining Japanese ships had no way out. However, despite the air threat of the Anti-United Nations, they continued to cooperate with the army's defense with naval artillery firepower. Even the Japanese Navy soldiers, whose ships were sunk by the bombing, were issued with rifle machine guns and incorporated into the army to participate in ground defense operations.

In order to protect the safety of the people in the city, the Anti-Japanese Federation did not even use artillery in the street fighting, let alone use aircraft? Therefore, it is very clear that in the deployment of anti-aircraft firepower, the Japanese army should focus on what position it should focus on, and the main anti-aircraft weapons in their hands will be deployed on both sides of the Haihe River.

In addition, the large number of anti-aircraft guns and anti-aircraft machine guns that were urgently installed on the Japanese ships and transferred from the warehouses of the Japanese Navy in Tianjin posed a huge threat to the attack aircraft group of the United Nations. Anyway, these warships only fought on a limited section of the river, and the Japanese did not consider the carrying capacity of the ships at all.

As long as there are vacant seats on the warship, anti-aircraft machine guns and single-barreled or multi-barreled 25-mm machine guns are installed. It was armed with a 25-mm anti-aircraft gun and a 13-mm machine gun, although its performance was very ordinary. However, the narrow river surface also restricts the route for the anti-United Nations attack aircraft group to enter, so that these anti-aircraft guns and anti-aircraft machine guns, which are not very good in performance, can also exert great power.

The Japanese army used the antiaircraft firepower of these ships, together with the army's antiaircraft artillery groups on both sides of the riverbank, to form a dense anti-aircraft fire network over the Haihe River to ensure the safety of the ships on the Haihe River. Despite the narrow river, the maneuverability of the Japanese ships was also limited. The Japanese ships could only maneuver up and down, unable to effectively avoid the air raids of the Anti-United Nations.

However, its dense ground anti-aircraft firepower made the anti-United Nations attack aircraft group participating in the war pay an unusually heavy price. In addition, only ordinary high-explosive aerial bombs and airborne rockets can be used for low-altitude dive attacks, and the means of attack are relatively simple. As a result, the results of the battle were not satisfactory, and the threat of Japanese ships could not be completely resolved.

Although the anti-coalition air forces that participated in the war braved the dense ground fire of the Japanese army to desperately assault. During the attack, they also destroyed one-third of the Japanese ships deployed on the Haihe River, as well as a large number of small gunboats converted by the Japanese army with civilian barges and 92 infantry guns. It even sank the entire flagship of the Japanese Navy's fleet deployed in Tianjin, and the destroyer Asahon with the largest tonnage.

The entire Japanese navy was deployed in the fleet in Tianjin, which was originally presented to the puppet state of Manchukuo by the Japanese navy. Later, he felt that it was not cost-effective to come back, and he was equipped with three 120-millimeter naval guns, and among the ships on the entire Tianjin battlefield, the destroyer with the strongest firepower was also sunk by the anti-United Nations air force.

However, during the air raids, more than 20 of the more than 30 attack planes deployed by the Anti-Union were shot down and more than 10 attack planes were damaged. This loss can basically be said to have reached the point of breaking bones for the air force, which was already the focus of deployment and was not on the battlefield in Tianjin. The aviation units that had lost almost all of the attack aircraft groups were no longer able to cooperate with the ground forces and had to withdraw from the battlefield altogether.
