For the Indians in the United States, the Eight Banners system was also a great progress in the social system, which naturally led to the great prosperity of the entire Yin Shang Mutual Aid Alliance. In the past, the Indians were a plate of scattered sand, and with the Eight Banners system, they were tightly united all at once, and the Chinese flag people couldn't run away if they wanted to, not to mention that they needed to huddle together to keep warm.

The Eight Banners is a system of integration of soldiers and people, and its original intention is to concentrate the full strength of weak tribes. The Jurchens are a fishing and hunting people, and the Indians are also fishing and hunting peoples, and what has been matched on both sides can no longer be matched. The children of China's Eight Banners, who have eaten the fruits of victory for more than 200 years, have been separated from the living environment of fishing and hunting for a long time, and have become decayed and degenerate. The Indians did not have this problem, they still maintained their true colors of fishing and hunting, almost as fierce as the flag men in the white mountains and black waters in the early Qing Dynasty. The North American militia that went west suddenly encountered this group of Indian Eight Banners whose style had changed greatly, but they saw the power of the original Eight Banners.

The militia raided Indian villages and never encountered any decent resistance, but the tribes in the alliance that had completed the reorganization of the Eight Banners were no longer so easy to bully. The militia marching west first encountered the Indian Eight Banners when they attempted to raid the Indians in the hills of the Rocky Mountains in Colorado.

When the hunting Indian flag men spotted the White People's Soldiers, they immediately sent back a warning message. Originally, the whites did a very clean job in slaughtering the village, and generally did not leave the finishing touches for the other tribes to know, lest the Indians be wary. It was precisely by relying on the paralysis and carelessness of the Indians that their sneak attacks were able to succeed again and again. But the propaganda of Mu Shun and others has done a good job, and now the Indians in the banner see the white people in the brigade, no matter what the real purpose is, they will treat them as if they are here to carry out massacres. Paishku in the village gathered the bannermen, and then sent people to ask for help, and moved the old and weak women and children to hide in the mountains.

Two companies of 270 militiamen had just finished arranging their formations, and the Indian cavalry, which had come and gone, had already gathered 1,500 cavalry and waited for them in the mountains. As the militia approached the pass, the Indian cavalry roared out and charged them from multiple directions.

After all, the weapons that Ma San resold were limited, and this small staff leader was a little far away from Arizona, where the core of the alliance was located, and had not yet been armed with Manchurian weapons. But they learned to use stirrups, and with this treasure their cavalry became even more invincible. Moreover, on a high-speed warhorse, attacking an enemy without armor with a bow and arrow can also achieve lethal results. The skilful Indian bannermen, all able to fire their bows continuously, did not have to slow down their guns at all, and they poured more than 10,000 arrows at more than 200 militiamen in an instant.

The militia who were suddenly attacked, just lined up in a phalanx, were half knocked down by bows and arrows before they could shoot, and when they tried to adjust again, the neighing war horses had already rushed in front of them. Infantry without machine guns, in the face of an absolutely superior cavalry charge, the regular army is a mortal, let alone these amateur militia. In what came to be known as the Slope of Despair, the Indian cavalry annihilated 270 militiamen in just half an hour.

The simple Indians were convinced that the way of heaven was a good cycle, so what the whites had done to them, they had to do the same, and the corpses of the two hundred and seventy militiamen were all scalped. The federal government, which heard the news, was furious, and despite the dilemma of the civil war, it resolutely dispatched a cavalry brigade and three regiments of militia to retaliate.

The Indians are no longer the scattered sands of the past, they are all banner people, and they have their own organizations. The leaders of the white people came to find a field, and they also had to call their bosses to come and help, and the Indians went out with white flags and all the flags, and gathered 50,000 cavalry to stand by in battle, so that the whites could also taste their own strength.

The Indian generals who have just been trained by Mu Shun are not only charged, but the war strategy of their hometown is guiding them. The Indian bannermen used all the tactics such as grain interception, harassment, and outflanking, and even took advantage of the advance of the main white force to dispatch a co-leader of 5,000 cavalry to slaughter the two white towns. When the American troops who were looking for a field reached the Desperate Slope, they were not only exhausted from insufficient supplies, but even cut off the rear route, and fought a decisive battle with the Indians in the worst state.

Although the state was not good, the U.S. military had the advantage of weapons after all, and the Gatling machine produced in North Manchuria vomited, and the Indians threw down hundreds of corpses and retreated. When the American colonel cheered for victory, he overlooked one thing, the Indians had an army of 50,000, why didn't they fight to the death! Recently, he is not only learning Chinese characters, but also reading books hard, and his daily reading is "The Art of War", and he wants to teach Americans what it means to avoid reality and make up for nothing.

The white flag, which lost the first battle, was not discouraged, and took advantage of its own lack of supplies and particularly strong mobility to bypass the main force of the US army. Then the army was broken into pieces, and the co-leaders frantically slaughtered the rear towns of the American army, almost killing the northeastern part of Colorado into a white no-man's land. The American colonel, who had just finished cheering for victory, had to turn his horse's head and chase after the startled horse's ass. However, the route of the startled horse's march was completely based on mood, and there was no trace at all, and the American troops were exhausted and did not find out where the enemy was.

After a month of running wildly, the two armies returned to the slope of despair, the American troops were exhausted and demoralized, and there were only more than 47,000 people left under the white flag. I have to say that the American people who went west did not eat dry food, and these guys with guns also had a certain combat effectiveness, and they swept the rear towns of the American army, which made the white flag pay a little price.

The U.S. military launched an attack again, but the startling horse did not accept the move, but went around the advantageous terrain of the desperate slope in circles, and the U.S. troops had no choice but to follow behind and eat dirt. At night, when the American troops camped, the Indians attacked and disturbed them, and they did not rob the camp, but they did not let the Americans sleep. After a week of commotion, the colonel found that his troops could not fight any longer, so he ordered a retreat to rest. The frightened horses refused to let them go, and on the way to the retreat of the American troops, the cavalry with white flags followed all the way, and finally launched the dawn offensive in the early morning when the American troops were sleepy.

The Indian white flag is not a Mongolian cavalry that does not dare to fight in close combat, and the tactical application of the horse is far superior to that of the monk Lingqin, but the gap in weapons cannot be made up by these alone. In the decisive battle of Desperate Slope, although the white flag defeated the American army and annihilated more than 3,000 people on the other side, he also paid the price of 7,000 deaths.

When the Horse returned to Arizona with the glory of victory and the title of hero, Mushun and Hatan did not greet him with praise, and the impulsive Horse caused a great disaster.
