On the western front, 150,000 Liang troops, 200,000 Yuke, 100,000 Yan troops, 100,000 Sun Guo, and 50,000 Wei Guo entered the territory of Changsun, but there was no actual action for a long time, and they were still waiting for the Qi, Chen, and Xu countries to prepare a new army to go to Changsun to join the division.

At the end of May, all the enemies in Jinye County were cleared, and the coalition forces continued to advance west and north after a few days of repair.

At the same time, bad news came from the Jin Kingdom, the Jin King Ji Jun died of illness, the crown prince Ji Jian ascended the throne to inherit the throne, Xiang Guo Fan Tao continued to serve as the Xiang State, the Jin State ushered in a political combination that was not embarrassing or embarrassing, and Wang Li had to return to China to preside over the state affairs.

He then left Gaoji to continue to negotiate with Xianguo, and Xianguo sent Taiwei Zhang You to the Jin State to mourn and inspect the economic situation of the Jin State.

In early June, the navy again broke out in a naval battle northwest of Boyang County, and more than 360 warships of the main armpit fleet arrived in the battlefield area under the cover of 27 iron canning ships.

A large-scale naval battle broke out on the 8th day of July, and the Xian army concentrated all its naval ships and torpedo boats to launch an offensive in two sea areas.

In July, when the typhoon season in the North Sea was in full swing and the weather was bad and the waves were raging, half of the warships of the Xian army benefited from the installation of two or three six-cylinder deflagration diesel engines, and their engine power was greatly increased, and the installation and use of new torpedoes and launchers greatly enhanced the decisive strength of the Xian army.

At the same time, the investment of the eight airships has helped to expand the horizon of the navy, and in order to solve the problem of wireless communication, the airboats are equipped with six three-color large strong lights, which provide great convenience for night light navigation and daytime combat situation transmission.

The naval battle lasted for two months, with five fierce battles, from the southern seas to the island chain of the northeastern outer islands, sinking 227 ships, including 15 ironclad canned ships, damaging 69 ships, including 4 ironclad canned ships, capturing 31 ships, including two ironclad canned ships, and capturing more than 77,600 sailors and infantrymen, 21 brigadier generals, 7 major generals, and 2 lieutenant generals.

The Xian army was sunk 86 warships and wounded 42 ships, 17 torpedo boats were sunk, 9 were seriously wounded, and more than 43,000 people were wounded.

In mid-September, the navy returned to Wangqinjiang via the coast to repair and replenish supplies, and replace seafarers to replenish warships.

Benefiting from the technology export policy in 653, the shipbuilding industry of the vassal states has matured in seven or eight years, and the Xian army has shifted its focus to manufacturing 20,000 stone warships and merchant ships, and the princes produce more 10,000 stone warships and merchant ships.

It not only satisfies the gap of current losses, but also brings a balance of trade to the princes.

At the same time as the naval battle of the Xian army, the Xian and Zhi armies attacked the two counties of Boyang and Daiping in August.

In order to get through the trapped Changsun people and remnants of Guangyuan County, the first, second, and third columns were transferred in July, and the Eighth Town Army was transferred to form the First Motorized Group Army, and the 106th, 107th, 108th, and 109th Columns were transferred north to participate in the battle, and the First Town and Fifth Column were transferred to China for repairs, and the 4th and 5th Towns and 70,000 soldiers from the reserve were transferred to Changsun to fill the defensive line.

In late September, a major offensive was launched against the junction of Boyang and Daiping counties, and in early October, the gap was opened, and Jiang Jie led the First Motorized Group Army to take advantage of the situation.

The 100 tracked armored vehicles previously attached to it increased to 150 at this time, and under the cover of the frontal offensive, they successfully broke through to the rear of the armpits, and have been rampage along the roads built by the armpits, inserting into the west of Boyang County and the south of Ai County, disrupting the deployment of the eastern front of the armpit in one fell swoop.

By mid-October, the battle situation on the Eastern Front was completely eroded, and Jiang Jie led the First Motorized Army to rush northward, not only breaking through the besieged Changsun County, but also inflicting heavy losses on the armpit road construction army and scattered troops behind the defensive line.

The coalition forces became more and more courageous, defeating the enemy in Boyang and Daiping counties in one fell swoop, and fully recovered the two counties in late November, opening up the Guangyuan counties that had been besieged for three years.

At the same time, the war on the Western Front was long overdue, and due to the major breakthrough made on the Eastern Front, the Western Front did not move his troops to make the Son of Heaven lose his face, so at the end of July and the beginning of August, he encouraged the princes to go on a northern expedition.

Due to the armored vehicles of the Red Army, the progress of the war was naturally due to the lack of ironclad vehicles to cover it.

And there is an even more fatal problem, the previous time three or four hundred howitzers were captured in a row, and they could not be pulled by people and mules and horses, and the unicorn was enough to choke, and it was extremely uncomfortable in the hot areas of the north.

In order to solve the problem of artillery traction and ammunition transportation, Xiao Gongyi asked Bailiyan for 1,000 taels of medium cards, but the princes did not have such treatment, so the efficiency of heavy artillery and artillery mobilization was extremely low.

By the end of October, the Western Front had launched two offensives, one without pain, and the other was caused by the defeat of the enemy on the Eastern Front, and the Western Front was exposed to the Xian Army's front, and the armpit was abandoned on his own initiative.

At the beginning of November, after two years of preparation, the first key hot bomb of the Xian Army arrived at the front line, and after carefully selecting the target, it was carried by air boat to Feiyuan County to carry out bombing.

All the senior generals from General Nerbi and below were killed, causing a total of more than 17,000 casualties and more than 6,000 minor and serious injuries, which directly led to the complete retreat of the enemy in Aijun, and was robbed and killed by Jiang Jie's First Motorized Army halfway, with heavy casualties.

On 14 November, Marshal Oka learned that the coalition forces had used key thermal bombs, causing more than 23,000 casualties, including Admiral Nerbi:

"No, these alien animals who have lost their conscience, I will kill them all......"

Admiral Masacolo, who was on the side, said dejectedly:

"The battle on the Eastern Front has collapsed, and we must draw the General Reserve and re-establish the defensive line on the Western and Northern Fronts of Nerbi. Judging from past experience, the attack of foreign animals lasted only six months to eight months, and now that they have been attacking and fighting continuously for more than half a year, I estimate that they will soon turn to repair and prepare for next year's war.

And Nerbi is surrounded by rainforests, which is very unfavorable for their rapid movement, and it is difficult for their transports to pass there. ”

"Then transfer reserves to the Eastern Front as soon as possible, and we must hold out until reinforcements arrive in March next year."

"Yes, Your Excellency."

As Masacolo expected, in late November, due to problems such as weather, injuries, logistics, and the livelihood of the people in the war zone, the Xian Army and the Zhi Army had no choice but to continue to move north, and the whole line was transferred to repair, rushing to transport the wounded to replenish the soldiers, appease the local people's livelihood, and solve the livelihood problems of tens of millions of people.

In view of the fact that some technical and tactical problems exposed by the Northern Expedition were successively made up and resolved in the second half of the year.

In particular, the canvas elastic chain is extremely unsuitable for tropical rainforest and humid climate warfare [Note 1], so the metal elastic chain was urgently developed and produced for front-line combat, and at the same time, the combat clothing was improved, and more ordinary camouflage clothing, rubber raincoats and long-brimmed hats camouflage baseball caps were distributed for shading and rainforest operations.

At the same time, more than 600,000 Jin troops in October of the whole training set off from Suidang, entered the capital county to take the train to Qingtian, and then went north to replace the Zhi army with serious casualties, and continued next year's operation, about 200,000 Jin army reserves, will be transferred north through Xianguo after the beginning of spring next year.

However, it was not for nothing that the Jin army was so "active" to go north, and the Xian army and the Zhi army won victories on the eastern front, which boosted the confidence of the Central Plains in the war of resistance and let the princes see that the war could end next year, or the year after, rather than the results of the armistice and peace talks.

At the same time, the Zhi army captured hundreds of thousands of guns and countless ammunition on the Eastern Front, and the biggest gain was the capture of gold with a total value of about 400,000 inches of gold, which greatly stimulated the Jin State to send troops.

The gold came from volcanic lava, and shortly after the armpit captured the eldest grandson, Mitsu Castle, he found that the lava from a volcanic eruption in a primeval forest more than 400 miles west had cooled down and contained gold, not sulfide, and the gold content reached 37 percent.

This volcano had been dormant for more than 2,000 years before that, and the continuous eruption in recent years was awakened by explosives at the instigation of the Xianjun advisers, and as a result, it sprayed and spewed gold.

If this was left thirty years ago, it is estimated that the eldest grandson would be able to see the whole Central Plains under his feet with such a cornucopia.

Seeing that it was profitable, he organized people to blow up the volcano in the area, forcing the volcano to erupt continuously, thus leaking gold.

At the same time, it was smelted on the spot into gold ingots and shipped back to the mainland, and the annual output was as high as 900,000 inches of gold, which was the largest economic source for the armpit invasion southward.

But paper can never keep the fire, and soon the news spread to hundreds, and when Bailiyan learned the news, this batch of gold had been shipped back to Zhiguo, which made him quite annoyed.

Because the key hot bomb in November cost 1,470,000 inches of silver, and 400,000 inches of gold can make three pieces. For this reason, Bailiyan made a special trip to Gongliangxiu to question, but he said that he didn't know about it, and the angry Bailiyan stomped his feet.

But it doesn't matter, no matter how much gold needs to be carried by the market, a large number of precious metals are put into the market, if there is no sufficient supply, gold will depreciate. If Zhiguo rashly uses this amount of gold to meet domestic expenses and pensions, it will inevitably be transmitted to the economic level.

Therefore, although the casualties of this year's Northern Expedition were very large, the capture was very rich, which was basically the same as the loss of the troops, and there may be a profit.

So after the withdrawal of troops in 661, Zhiguo still stationed more than 20,000 people in Mitsu Castle, specializing in this side business.

Of course, if you don't allow others to engage in a side business, it will be a big mistake, and the Xian army soon flocked to collect gold, and directly transferred five 200-millimeter howitzers, and urgently developed a special gas mask specially for dealing with volcanic ash and distributed it to the local garrison.

Although they knew that such a large-scale destruction of the volcano would cause geological disasters, they could not care so much about it for the sake of war.

Moreover, the vast majority of the radius of four or five hundred miles is primeval forest, and geological disasters are not enough to affect human life.

In the first month of 661 in the Shengyuan Dynasty, King Xian inherited the practice of the first month of last year, and set up a state banquet in the Hong'en Palace, banqueting meritorious generals and soldiers, and giving cash rewards, and the proportion of soldiers increased fourfold compared with last year, reaching ninety-two, in recognition of which battles have produced grassroots officers and soldiers.

On the fifth day of the first lunar month, King Xian still feasted the Son of Heaven and the princes in the Hongen Palace, and reported the results of last year's battle, but never mentioned the Mizu gold.

Due to the few achievements on the Western Front, the banquet became a stage play for King Xian to show off alone, and the other princes did not feel disgraced, and even took it for granted, but the embarrassment of the capitalization on the face of the Son of Heaven was always embarrassing and lingering.

[Note 1] Regarding the canvas bullet chain and the metal single chain, the appearance of the canvas bullet chain has its inevitable reasons, and at the beginning of the appearance of the machine gun, it was not without thinking about the metal bullet chain.

Looking at the metal elastic chain rest is a simple thing today, any stamping processing enterprise on the scale can make it, but one hundred and thirty years ago, the processing difficulty of the metal elastic chain is not smaller than that of the bullet case.

The development of metal elastic chain requires higher precision stamping and forming technology, due to the high performance of elastic chain metal materials, it belongs to tool steel, not bullet case brass, and requires higher stamping die material technology.

Therefore, without solving the problem of precision stamping, forming and die materials, the metal elastic chain cannot be talked about at all, so the canvas elastic chain can only be used.

Due to the inability to use metal elastic chains in the early days, and the canvas elastic chains had the problems of swelling when exposed to water, mildew, easy tearing, and poor reliability, so there was a compromise technology, drum and magazine.

Through magazines and drums, a certain degree of firepower sustainability is guaranteed.
