【Grudge against Gongsun】

In the first year of Chuping (190), under the call of Dongjun Taishou Qiaomao, all the princes united to crusade against Dong Zhuo, which started the beginning of the troubled times.

After Dong Zhuo's rebellion, Qingzhou assassin Shi Jiao He also decided to unite other princes to crusade against Dong Zhuo, but because he transferred too many troops, Qingzhou was empty, and the remnants of the Yellow Turban Army took the opportunity to enter, as a result, Jiao He's army had not crossed the Yellow River, Qingzhou was already in chaos, and Jiao He was forced to turn around and suppress the Yellow Turban thieves.

But Jiao He was greedy for life and afraid of death, and under the superior military strength, he was led by the nose by the Yellow Turban thieves, which made the originally rich Qingzhou a mess. After Jiao He died of illness, Qingzhou was left without an owner, and the Yellow Turban thieves in Qingzhou and Xuzhou were even more unscrupulous, preparing to enter Jizhou and join the Montenegrin army.

At that time, the Yellow Turbans in Qingzhou and Xuzhou were recorded to have as many as 300,000 people and huge forces, but they did not expect Gongsun Chan to suddenly insert a pole, and the Yellow Turban Army in Qingzhou and Xu Prefecture was defeated by Gongsun Chan, suffered heavy losses, and was forced to turn to Yanzhou instead, and the convergence with the Montenegrin Army in Jizhou was not completed.

So in history, although the Montenegrin Army and Gongsun Chan were eventually allies, the two sides were a little resentful at the beginning.

【United Anti-Yuan】

Although Gongsun Chan prevented the convergence of the Montenegrin Army and the Qingzhou and Xuzhou Yellow Turban Army in Jizhou, he did not directly target the Montenegrin Army after all, on the contrary, through this battle, Gongsun Chan showed his strong strength to the Montenegrin Army.

Of course, this is only one of the reasons why the Montenegrin Army decided to unite with Gongsun Zhan, Yuan Shu and others to fight against Yuan Shao, Cao Cao and others.

In history, Yuan Shao, as the leader of the anti-Dong coalition army, not only failed to complete the great cause of opposing Dong, but instead seized the territory of the allies and dragged his younger brother back, which is very despicable at this time. Moreover, Yuan Shao and Cao Cao were also very weak in the process of fighting against Dong Zhuo, Cao Cao didn't say anything, they were all abused by Xu Rong in the Battle of Bianshui, and Yuan Shao, as the leader of the alliance, the army under his command was almost wiped out by Dong Zhuo in the Heyangjin area.

In contrast, Yuan Shu and Gongsun Zan showed much stronger strength on the battlefield. Sun Jian, the general under Yuan Shu, first defeated the crusading army of Hu Zhen and Lü Bu, and also showed the head of Hua Xiong, the general under Dong Zhuo, and then defeated the main force of Xiliang led by Dong Zhuo himself in the area of the mausoleum of the first emperor, and finally captured the old capital Luoyang guarded by Lü Bu. If it weren't for Yuan Shao sending Zhou Ang to attack Sun Jian's rear, even Yuan Shu and Sun Jian might have hit Chang'an directly.

And Gongsun Zhan directly defeated the Yellow Turban Army of Qingzhou and Xuzhou, allies of the Black Mountain Army, and its strength is even clearer.

In terms of strength comparison, intuitively, the strength of Yuan Shu and Gongsun Zan is more dominant, and Yuan Shao, Cao Cao and others did not seem very strong at the beginning.

But these are not the fundamental reasons why the Montenegrin Army chose Gongsun Chan and Yuan Shu, Zhang Yan will lead the Montenegrin Army to help Gongsun Chan and Yuan Shu fight against Yuan Shao and Cao Cao, or it has a great relationship with his own vital interests.

In history, the Montenegrin Army as the remnants of the Yellow Turban Army its main scope of activity is also in the Jizhou area, so they naturally take Jizhou as their main goal, Yuan Shao became the pastor of Jizhou, because the territory is close, so Yuan Shao is not only the main enemy of Gongsun Zhan, but also the primary enemy of the Montenegrin Army, in contrast, the Black Mountain Army in Youzhou has little power, and Gongsun Chan has no conflict.

The situation in Yanzhou was similar, earlier Yu Poison, Bai Huan, Zheng Gu and other Montenegrin generals invaded Yanzhou East County, but Cao Cao sent troops to repel them, and thus formed a grudge with the Montenegrin army. Later, after the failure of the Montenegrin Army and the Qingzhou and Xuzhou Yellow Turban Army in Jizhou, they began to transfer to Yanzhou on a large scale, making a mess of Yanzhou.

However, after Cao Cao became the pastor of Yanzhou, he gradually forced the Yellow Turban Army in Yanzhou to a dead end, and the Yellow Turban Army in Qing and Xu Prefectures was forced to surrender to Cao Cao for their livelihood, and the elite was also incorporated by Cao Cao as the "Qingzhou Soldiers".

Therefore, later, the Montenegrin army successively sent troops to support Gongsun Zan to defeat Yuan Shao and Yuan Shu to attack Cao Cao, but they did not achieve victory, on the contrary, they suffered a lot of losses.

But the Montenegrin army did not give up, especially against Jizhou, which was close to them.

[Montenegrin Army vs Yuan Shao]

In the fourth year of Chuping (193), due to the threat of Liu Yu in the rear, Gongsun Chan sued Yuan Shao for peace under the mediation of the servant Zhao Qi, and Yuan Shao and Gongsun Chan temporarily ceased war.

However, at this time, there was a mutiny in Wei County, and the rebellious soldiers and the Montenegrin army general Yu Poison and others met and occupied Yuan Shao's base camp Yecheng, and killed Taishou Licheng. After the news came, the whole army was shocked, especially those whose families were in Yecheng, one by one worried, shocked, and even some people stood up and cried directly, but Yuan Shao looked calm and did not change his usual demeanor, just like his family members were not in Yecheng.

Seeing that the leader Yuan Shao was calm, the others finally stabilized slowly.

At that time, there were more than a dozen troops of the Montenegrin army in the whole Yecheng, among which there was a man named Tao Sheng, who called himself "General Pinghan", who rebelled against other thieves alone, he led his troops to climb over the city wall from the west into the city, closed the county government, loaded the baggage into the car, and personally escorted the family of Yuan Shao and other officials who lived in Jizhou City to the Qiuqiu. Yuan Shao then led a large army into Qiqiu, and appointed Tao Sheng as the general of Jianyi Zhonglang.

Yuan Shao opened the clarion call for a counterattack against the Montenegrin army, and later when he was crusading against Zhang Yan, Lu Bu also came to join Yuan Shao, adding a great battle power to Yuan Shao's army.

In June of the same year, Yuan Shao then sent troops into the valley mouth of Cangyan Valley in Chaoge Lugu Mountain, attacked Yu Poison, and defeated Yu Poison in only five days, killing Yu Poison and more than 10,000 people of his subordinates. Then Yuan Shao went north along Lugut Mountain to attack Zuo Zhangba and other thieves and wiped them all out. He also attacked Liu Shi, Qingniujiao, Huanglong, Zuo Xiao, Guo Daxian, Li Damu, Yu Yigen and others, and again killed tens of thousands, destroying all their camps.

Then Yuan Shao and Lu Bu and others launched a fierce battle with Zhang Yan, the leader of the Black Mountain Army, when Zhang Yan united the four battalions of the Xiongnu Tu Division, Yanmen Wuhuan and other foreign tribes, and he also had tens of thousands of elite soldiers and thousands of cavalry under his command, and his strength was not weak. Yuan Shao fought with him in Changshan, the two sides fought for more than ten days in a row, due to the courage of Lü Bu and others, Zhang Yan's army suffered many casualties, and Yuan Shao's army had the upper hand.

But after a long battle, Yuan Shao's army was exhausted, and Lü Bu also had different intentions and took the opportunity to expand his sphere of influence, so Yuan Shao and Zhang Yan each retreated.

After this battle, Yuan Shao dealt a heavy blow to the Montenegrin Army, and his control over Jizhou was also greatly strengthened, but because the Montenegrin Army was mainly active in the mountainous areas, and Zhang Yan's strength was not weak after years of training, Yuan Shao failed to completely eliminate the Montenegrin Army, and the threat of the Montenegrin Army to Yuan Shao still existed.
