In the face of the demands put forward by the US side, after urgent discussions with the central authorities, Yang Zhen agreed to the US military's request. Pen & Fun & Pavilion www.biquge.info but Yang Zhen resolutely disagreed with the idea put forward by the Americans that the Anti-United Nations would only send out ships and the Americans would take over the war. Instead, they resolutely demanded that the ships participating in the war must be piloted and operated by anti-coalition personnel.

Regarding Yang Zhen's tough attitude, the anxious Americans finally agreed to Yang Zhen's request. Immediately, more than 20 ships were dispatched to Lushun and the gunboat group of the Anti-Japanese Union was rushed to the waters of Iwo Jima. And send a fleet repair ship to provide maintenance support along with it.

Although these small gunboats are flexible, they can only operate in the near sea, because the tonnage is too small and they have no ability to sail long distances. Without the towing of large ships, it is impossible to reach the waters of Iwo Jima on its own. The Americans also knew this, so they sent ships to Port Arthur to meet them.

And Yang Zhen also consciously took this rare opportunity to exercise his small fleet. He basically transferred all the ships that could carry out operations. Even the river gunboats that were withdrawn from the Songhua River were all sent out to participate in the battle.

These small gunboats dealt with the large and medium-sized ships of the Japanese Navy, and they were delivered to the door. But it was quite effective against the odd number of Japanese suicide boats. These small gunboats and gunboats sent by the Anti-Japanese Union just made up for the lack of mobile and flexible small ships of the US fleet on Iwo Jima, and the temporary modification of the landing craft was not efficient because of its poor seakeeping.

Although the gunboat fleet and small gunboats of the Anti-United Nations could only undertake combat defense in one direction due to their numbers, they also greatly reduced the pressure on the US military. In this bloody battle, which lasted for a month and a half, although the gunboat team of the Anti-United Nations only participated in the second half, it sank more than 100 Japanese suicide speedboats, effectively ensuring the safety of the US fleet.

Although it was also attacked by the Japanese Huitianren torpedoes, as well as Zhenyang suicide boats and suicide planes, it lost several gunboats and one gunboat. But through this battle, the troops have been trained and a lot of experience has been learned, and Yang Zhen thinks that this price is still worth it.

This small gunboat flotilla and five gunboats did not return to Arthur immediately after the Battle of Iwo Jima. In the midst of this battle, the commander of the Admiral of the Third Fleet of the United States Navy, who was overwhelmed by the unusually large number of suicide speedboats of the Japanese, did not let this small anti-Union fleet, which was mainly composed of small gunboats, return.

And the Americans did not let go, and Yang Zhen was not in a hurry to transfer this fleet back. This small fleet, which is precisely the gunboat team, followed the US army to participate in the Battle of Okinawa before returning to Lushun at Yang Zhen's repeated requests. When the U.S. admiral returned from this small fleet, he also generously presented five LCM landing craft and two LCT landing craft to the Anti-United Nations as compensation for the loss of several gunboats.

In addition to sending the only fleet to participate in the battle, Yang Zhen basically sat on the mountain and watched the tiger fight during the entire Iwo Jima campaign. It was not until the Battle of Iwo Jima in March had come to an end and the fall of Iwo Jima into the hands of the US military had become a foregone conclusion, that he approved Du Kaishan to launch an offensive on the front line of Jinhua and Cheorwon.

Although Yang Zhen pushed back the time of the campaign for almost a full month. Du Kaishan and Ma Chunsheng organized the forward troops and conducted detailed reconnaissance of the enemy situation in the predetermined combat area on many occasions. And on the front line of Wusheng Mountain, many drills were carried out.

However, after the Jinhua and Tieyuan fronts were fully launched, the progress was not as smooth as Du Kaishan originally imagined. The overall deployment of Du Kaishan is to take Cheorwon as the core, and deploy the strength of one regiment on the north and south sides of Cheorwon, with the Gaotai Mountain, Jinhe Mountain, and the northern highlands of Munhui-ri as the main points of contention.

If the battle goes well, the two regiments continue to attack southward, trying to advance the front south to the Imjin River. A tank battalion and an infantry battalion were attached to the Gyeongui Railway and launched interspersed operations in the direction of Yeoncheon to cut off the connection between the Japanese troops in front of them and the enemy forces in the area west of the Gyeongui Railway.

A regiment was deployed west of Jinhua, with one howitzer and one heavy mortar. Carry out a company-platoon-level pull-out operation in the hilly area north of Jinhua. The strength of one regiment was used as the general reserve, and the front between Jinhwa and Cheorwon was monitored. At the same time, the troops on both flanks launched a diversionary attack on the line from Heituyunling to Dacheng Mountain east of Shuoning and Jinhua.

For this operation, Du Kaishan specially moved his headquarters from Pyongyang to Pyongkang. Ma Chunsheng, who was in charge of the front-line command, placed the headquarters in the east curtain north of Tieyuan, only a stone's throw away from the battlefield. These two almost took a step-by-step approach to command the campaign.

However, to the surprise of the two people, the North Korean army did not hastily increase its troops after finding out the offensive strength of the Anti-Japanese Alliance, but only relied on a 137th Division on the Cheorwon battlefield to repeatedly fight with the in-person Anti-Japanese Alliance. In the direction of Jinhua, it only relied on the original deployment of the 133rd Brigade and the 1st Independent Brigade, relying on the mountains on the periphery of Jinhua to hold Jinhua.

The only adjustment was to transfer four infantry squadrons from each of the four wings of the 150th Division, which was originally between Pochon and Seoul, to be attached to most of the divisional rapid-fire artillery team, as well as a rocket artillery team, the latest weapon of the Japanese army, and two squadrons of the heavy artillery wing of the 58th Army, to take over the in-depth defense of the 137th Division in the area north of Pocheon.

So that the 137th Division could free up its hands and go all out to deal with the anti-coalition offensive in the Cheorwon direction. However, the main force of the 150th Division still held the line from the Imjin River to Kaesong. However, after the battles of Cheorwon and Kimhwa, the Korean army significantly strengthened the defenses around Seoul.

The 137th Division of the Japanese Army, which was deployed south of Cheorwon, in addition to retaining the two infantry brigades belonging to the 376th Wing, served as mobile forces and reserves. Most of the troops were formed in squadrons and squads, and they were scattered to the hilly terrain south of Cheorwon and on both sides of the Hantan River.

In each of the heights south of Cheorwon, a squad with reinforced firepower was deployed. And around these heights, on each of the main hills, a squadron was deployed with the same increased firepower. In accordance with the characteristics of the entire Cheorwon battlefield, a certain amount of mobile forces have also been deployed between the first-line and second-line, and between the second-line and third-line troops.

At the same time, the 137th Division did not compete with the Anti-Japanese Union, which was unfavorable to the terrain and was conducive to the heavy firepower of the Anti-Japanese Union. Instead, with the support of artillery in depth, the existing fortifications resisted point by point, relying on the surrounding area of Cheorwon and the mountainous areas to the south, and it could almost be said that every inch of land was contested.

Every hill in the entire Cheorwon battlefield had to be fought over and over again before the ownership could be finally determined. Cheorwon, a small town in the mountains, was completely razed to the ground on the first day of fighting. On the battlefield, which is more than 10 kilometers wide from north to south and more than 20 kilometers long from east to west, the two sides fired an average of about 10,000 shells a day.

However, in this operation, although the Japanese army invested in the resistance to the United Nations was limited. Although the major adjustment was not carried out, the firepower was greatly strengthened. Not only the entire artillery of the 137th Division, but also half of the artillery of the 150th Division.

With the development of the battle, nearly one-third of the artillery directly under the DPRK Army and more than 20 large-caliber howitzers were successively put into operation. For the first time, the latest Type 4 203-mm rocket launchers and Type 5 150-mm rocket launchers were also launched.

In particular, in the Iwo Jima operation, it cooperated with 240mm howitzers, posing a serious threat to the US forces on the beachhead. Although the firing range is somewhat short, the launch device is extremely simple, and the Type 4 203 rocket launcher that can change places with one shot has also brought great trouble to Du Kaishan's offensive in Tieyuan.

In addition to the artillery, which was equipped with the latest equipment, the infantry was in addition to light and heavy machine guns and imitations of German Iron Fist rocket launchers. During the Battle of Cheorwon, in order to deal with the tanks of the Anti-Japanese Alliance, the Japanese army also put the latest four-type 90-millimeter rocket launcher into the Cheorwon battlefield.

This latest anti-tank rocket launcher of the Japanese army, in terms of range and power, is not comparable to the imitation German iron fist bazooka originally used by the Japanese army. These rocket launchers are deployed along the Gyeongui Railway, as well as along the Cheorwon-Chipuri Highway. Brought great losses to a tank battalion invested by Du Kaishan.

The tank troops put in by Du Kaishan only advanced less than ten kilometers south along the Gyeongui line. Under the intensive anti-tank fire of the Japanese army, coupled with a large number of rocket launchers, nearly half of the tanks were lost. An infantry battalion that served as cover also suffered heavy casualties under the crossfire of Japanese troops in the mountains on both sides and had to retreat to the starting point.

At the same time, during the forward attack operations, Ma Chunsheng organized many small-scale roundabout interspersed operations, and most of them ended in failure under the strict defense of the Japanese army in front of him. The 137th Division, which was in front of it, obviously carefully studied the tactics of the Anti-Japanese Union in the eastern battlefield of Kaiyuan during the period of the South Manchurian operation, and adopted targeted arrangements.

The 137th Division's early preparations made Ma Chunsheng's interspersed operations almost all defeated, and he could only push hard from the front. However, the continuous mountains south of Tieyuan made the progress of Ma Chunsheng's frontal attack unusually slow. After three days of fierce fighting, the attacking troops on the front line of Cheorwon failed to complete the planned operational objectives of seizing Gaotai Mountain and Munhuiri.

The attacking troops paid a great price, capturing only a few heights south of Cheorwon and Jizo Peak. In the area east of the Hantan River, only the highlands north of Munhye-ri were seized. On the Jinhua battlefield, although the first line of Shaguli was captured, when advancing to the front line of Fugui Mountain, it was met with extremely stubborn resistance.

The continuous attack paid a lot of price, but the progress was unusually slow, which made Du Kaishan quite dissatisfied. But he was not satisfied, but he tried to intersperse failures many times within three days, allowing him to repeatedly stabilize Ma Chunsheng's mood, which was obviously a little impatient. Considering that the losses of the participating troops were not light after the three-day attack, Du Kaishan was urgently transferred as a regiment of the 10th Division of the General Reserve of the Central Korean Battlefield to the north of Cheorwon and stood by.

And after gritting his teeth, Du Kaishan also transferred the artillery reserves, trying to concentrate the artillery group to first destroy the Japanese rocket artillery that had a short range but was not very powerful. At the same time, Du Kaishan demanded that the covering troops on both flanks change from a feint attack to a real attack and increase the intensity of the attack.

For Du Kaishan, who was obviously a little impatient, Yang Zhen repeatedly replied to ask him to stabilize, and the general reserve team in his hand was easily not allowed to be transferred. At the same time, Yang Zhen resolutely stopped Du Kaishan from transferring another brigade to the central front from the units left behind by the Korean Independence Army and being reorganized, and he was transferring an armored unit to strengthen the request in the direction of Cheorwon.

Although they were no less surprised by the new tactics adopted by the Japanese army. However, after careful consideration, Yang Zhen replied to Du Kaishan's repeated requests: "Attack with the existing forces and find a way to deal with the new tactics of the Japanese army in the battle." Don't be too impatient, be sure to stabilize your emotions. Attention should be paid to the new tactics adopted by the Japanese army, and more local adjustments should be made in the specific deployment of front-line troops. ”
