On December 23, Daejeon fell, the brave Fourth Division once again transferred to Gwangju and retreated to Gwangju, and the 19th Division also gave up Sangju Gimcheon and transferred to Daegu, while the 9th Wing of the 5th Division under the leadership of Suzuki Shoroku basically retreated, from Jecheon to Yeongju Andong and finally to Gyeongju to stabilize its position.

Just when the Wehrmacht was advancing again, the first wave of Japanese reinforcements finally arrived, and the 6th Division, the 3rd Division, and the 9th Division, the elite packhorse division of Ilshui, began to march to various cities from the shore above Busan, and finally formed an absolute defense circle based on the Nakdong River, and also transferred General Yamanashi Hanzo from the position of director of education to serve as the commander of the Samhan Dispatch Army.

In the face of the opponent's dense strength of five and a half divisions, the three divisions of the Seventh Army (two infantry divisions and one quick response division) plus three infantry divisions and one armored division of the Eighth Army must bear heavy casualties, and for the sake of the interests of the stick, the Wehrmacht did not think that it needed to pay the price of more than 10,000 casualties, so in the first month of the 14th year of the Republic, the battle front was basically stable, and the regime of the Republic of Samhan, which built the capital of Seoul, was helpless. Two of the four columns were arranged by the Wehrmacht to spread and defend on the east and west coastlines, that is, to be a guard post, if Japan planned to make a trick of landing at Incheon, at least it would have to drag the Japanese army for more than 24 hours, and the two group armies of the Wehrmacht were stationed in Yeongju, Daejeon, Gwangju, Seoul, Haiju, Gangneung, Hamcheon, Pyongyang and other places.

Although the battle line has stabilized, the small fights between the two sides are still continuous, especially the two compound ** columns on the front line are even more fluttering by the previous results.

The Fourth Column attempted to break the stalemate at Xiaobeishan, west of Mashan in the south; They are also launching a fierce attack on a place jutting out of the Luodong River in the west of Lingshan, trying to find a breakthrough.

One of the divisions, Samhan Fu**, attempted to assist in the attack by crossing Yeongpo on the Goryeong-Daegu road to the south.

To the north and northwest of Daegu, the 3rd Column of Samhan Fu ** launched the main attack, and actually drove the troops of the Japanese 19th Division to a distance of 12 miles from Daegu.

At the same time, two divisions of the Fourth Column broke through the Taibai Mountains on the east coast and launched a flank attack on the 3rd Division, which was fighting the 9th Mechanized Infantry Division of the Wehrmacht 7th Army near Yingde.

A wing of the 3rd Division, which was forced to the sea, had to break out from the sea.

The third column of Samhan Fu ** then occupied Pohang-dong.

Later, under the fire of the Japanese Navy destroyers, they were driven out again.

Samhan's re-** forces have posed a threat to the nearby Yingri airfield, forcing two Japanese fighter squadrons to withdraw from the airfield.

But in the fierce fighting on the critical Northeast Front, the Japanese 6th Division held the front.

By January 20, they drove Samhan Fu** into the mountains northwest of Pohang-dong.

The northern part of the Busan Ring of Defense shrank 15 to 20 miles inward, but not again.

On the line of the Nakdong River, the defensive line was not broken through, despite the fact that the enemy temporarily penetrated into the depths.

However, for a while, the Japanese commanders did fear that they would be breached.

The main reason for the victory of the present Japanese army is that the vital Busan-Gyeongju-Daegu-Pusan railway loop in the defensive circle is working extremely well under the control of the conductors of the army transport troops, which successfully takes on the heavy responsibility of transporting supplies, and finally allows each unit to receive enough weapons and ammunition.

The railway supply system allowed the artillery to storm the assembly sites of Samhan's re-army, and also enabled Admiral Hanzao Yamanashi to quickly move troops from one place in the defensive ring to another in an emergency.

The age-old statement that troops fighting on the inner front are more flexible than those fighting on the outer front is confirmed in the battles of the defensive ring.

The Japanese army was backed by the port of Pusan and had sufficient, even abundant, supplies, that the Wehrmacht could rely on the western route for transportation from the country or by sea from the port of Mupo in Gunsan, while Samhan Fu ** supplies were generally pitiful.

The 3rd Korean Column, which was fighting on the Northeast Mountain Front, was not only forced to return its artillery to the rear because of its lack of ammunition, but also received no supplies at all in early February, forcing the troops to search for food in nearby villages at night.

For the first time, the Busan Defensive Ring gave the Japanese the opportunity to establish a relatively continuous front after several defeats, with troops defending on the left and right flanks and reserves in the rear, which was the linear mode of warfare that the Japanese were familiar with.

The reconstruction of this front has provided timely security for the Japanese officers and men and greatly enhanced the combat effectiveness of the Japanese army.

On the Nakdong River, the tactic adopted by Admiral Hanzo Yamanashi was to establish a series of strongholds on the highest peaks on the east bank of the river.

Standing on these strongholds, the Nakdong River and all the roads from the Nakdong River to the U.S.-controlled area are in full view.

There were not many people defending these strongholds during the day, and they were only used as observation posts.

At night, these strongholds become listening posts and small defensive circles.

The task of the observation post is to act as a forward listening post and a tentative line of defense for the outpost, alerting the commander as soon as an enemy attempts to infiltrate are detected.

The real battle on the front line of the Nakdong River was to be left to the reserve troops a few miles away from the river, who were ready at any moment to launch a counteroffensive against the infiltrating enemy.

This was an excellent system, as it allowed the Japanese to concentrate their forces to the maximum extent possible to attack wherever they were in danger.

Artillery and mortars deployed behind the river bank can fire at proven and other crossings, or they can be concentrated in a limited area.

Japanese machine guns could fire at a channel that the Koreans could use, and artillery could be used to bombard.

The most important weapon was the howitzer, and the Japanese army quickly became a supporter of artillery doctrine at the expense of the artillery of the Chinese Defense Forces.

Along the Nakdong River, with several heavy artillery clusters of the Wehrmacht not yet in place and few supplies, Japanese artillery had quickly regained its traditional dominance of warfare.

By February 5, Samhan's troops had crossed the Nakdong River three times.

The second time was from the defense area of Sanhan Jing** north of Wakan, and the third time was 30 miles south of Wakan, where it was directly opposite Lingshan and was the defense area of the Ninth Division.

The last crossing of the river was extremely dangerous and posed a threat to the entire defensive circle.

If the enemy broke through to Yeongsan, it would be possible to cut off the Japanese army north of the Nakdong Gangwan and the 4th Division around Masan, and it would also be possible for Fu ** to break through from the east of Yeongsan into Miryang, thus cutting off the main railway and road from Daegu to Seoul, with disastrous consequences for the supply of the Japanese army.

The attack was launched by the 4th Division of the 3rd Column, which had been well known at the time, and which, together with the 3rd Division, pursued the Japanese along the Hanbu Highway.

The offensive target of this division was the so-called "Nakdong River River"

, 3 miles north of the confluence of the Namgang and Nakdong rivers, was defended by the 34th Wing.

At midnight on February 5, Samhan's army launched an offensive without prior artillery preparations.

They crossed the river on rafts, or simply took off their clothes and crossed shoulder-deep water to the east of the bay on a 2.5-mile-long north-south ridge.

The ridge is about 3 miles away from the river bank and is called the "Alfalfa Leaf Highland"

From the south, it is called "Wufengli Ridge"

Between the two highlands is a low pass, and there is a path leading to Lingshan.

Several battalions of the 4th Division all crossed the river, and the artillery and baggage of the troops crossed the river with the help of underwater bridges.

This is the Soviets in World War II had frequently used this kind of bridge, and later the volunteers also used it in Samhan, obviously Wu Chenxuan brought this technology to the Wehrmacht, and the Wehrmacht selflessly taught the Samhan Fu ** people this bridge building technology, in addition to preventing air raids, it is also very good for the advance route of the concealed troops.

Samhan Bok** widely used such underwater bridges on the Nakdong River, they are made of sandbags, stones and logs.

The foundation of the bridge is laid on the riverbed, about 1 foot above the water.

Japanese artillery observers had difficulty navigating the muddy river bridges, and the soldiers and cars of the Korean army, who were often stunned, were gliding across the Guò River, so they played a large role in transporting artillery and baggage.

On 11 February, an attack by a battalion of the 19th Regiment and the 21st Regiment of the 3rd Division, which had just arrived, failed to drive the enemy troops away from the Alfalfa Heights and Wufengli Ridge, and the attack failed.

At the same time, Samhan Fu** took action around the main battlefield of Jiangwan and opened artillery fire on Yeongsan, 5 miles east of Jiangwan.

Some of the soldiers also infiltrated the eastern part of Lingshan and set up a strong barricade on the road to Miryang.

To the south of Yeongsan, Wehrmacht troops took out a Japanese patrol defending a bridge over the Nakdong River by surprise at Namji-ri.

If Samhan Fu ** is not driven away, the 19th Division south of the Nakdong River will fall into an isolated and helpless situation.

Faced with this critical situation, Admiral Hanzo Yamanashi ordered Masan's reserves, the 45th Wing of the 9th Division, to attack north and recapture the Minamijiri Bridge.

The 45th Wing took the bridge in one fell swoop and dispersed about 2,000 Samhan Fu** infantry in the course of the attack.

At the same time, the 9th Division sent troops to break through the barricades east of Miryang; A temporary squadron of orderlies, baggage officers and staff officers formed by the headquarters of the 6th Division marched westward to prevent further penetration of the Korean army into the rear of the division headquarters.

The next day, three Japanese troops, the 45th Wing, a brigade of the 9th Division, and a brigade of the 5th Wing of the 5th Division, which had just arrived from Miryang, met in front of the barricades set up by the enemy on the east side of Lingshan.

The attack drove away the defenders there, some of whom were killed, while the rest scattered and fled.

General Yamanashi Hanzo took decisive action and quickly mobilized men and horses from several places to eliminate the danger of Samhan Fu** infiltrating into Miryang, and the Japanese troops of the two divisions were able to force the advancing Samhan Fourth Column back to the other side of the Nakdong River.

The heavy casualties of the three Han Fu ** only changed less than 30 square kilometers of territory, and the Wehrmacht rarely provided air support in addition to providing artillery support, such as Jin Jiu, Zheng Bongjoon and others have already been somewhat aware that the Chinese Defense Forces are deliberately letting the Fu ** and the Japanese army fight for attrition, and some generals with independent ideas have expressed their disappointment in front of the Japanese defense line. Maybe the meaning of the Celestial Empire is to let those guys who don't know the height of the sky understand that it was not them who destroyed the Japanese garrison some time ago, but the National Defense Force, and it is better to have a clear position.
