Zhang Yunkai opened the bushes in front of him and put a group of green battalion soldiers 150 steps away into the crosshairs.

Beside him, 8 soldiers made the same move.

There were about 100 soldiers in the green battalion, a small number of them were armed and guarded, and most of them gathered around a few fires, roasting the carcasses of some animal, looking very excited.

In the Tatar army, the green battalion soldiers were not only combat troops, but also coolies who transported food, cut wood, fetched water, and fought hard.

Uncle Eight Banners won't do these things, so he can only work hard for the Green Camp brothers.

Zhang Yunkai pulled the trigger.

The hammer clamped the flint and rubbed it heavily on the anvil, causing a cloud of sparks, and the anvil moved downward while pushing the lid of the medicine pool, and the spark ignited the propellant, and the bullet flew out of the chamber of the gun.

Captain Zhang Yunkai fired the first shot, and almost at the same time, the rest of the rifle squad also opened fire on their respective targets.

The Green Battalion soldiers on the opposite side fell one by one, and the young soldiers who were watching with binoculars reported that two people had been shot.

The first shot hit rate was about 20%, and Zhang Yunkai was very satisfied. Reload, and pound the bar hard, so that the bullet deforms more violently.

The second shot was not easy to fight, and the green battalion soldiers were tortured by the rifle for half a year, and they probably knew how to find cover to dodge.

The shooting was already very close to the Shanxi Green Camp station.

After the battle of Jiang Pin, the strength of the Shanxi Green Battalion is not strong, and the Green Battalion of Tong Province is only 20,000 soldiers, and this time 5,000 troops were dispatched, and the departments of Datong Town, Taiyuan Association, and Governor Standard Battalion were transferred to the unified command of Peng Youde, the chief soldier of Datong Town.

Zhang Yunkai and his team each fired 6 shots, but when they saw that it was difficult to achieve any more results, they collected their guns and left.

The literate young soldiers wrote down today's results in a small notebook and hit 8 green battalion soldiers. Although only half of the results were confirmed, this did not prevent Zhang Yunkai from estimating more.

In the past six months, Zhang Yunkai's team has achieved a total of 213 results, and the records of other teams are generally similar, not far behind.

On the entire Bobai and Yulin fronts, there were more than 300 rifle troops, and most of the guns were bought by the units themselves.

Zhang Yunkai's squad was one of them, and in addition to the riflemen, there were more than 20 soldiers equipped with other weapons.

In order to facilitate the march in the mountains, the soldiers were not equipped with armor, some brought shotguns and waist knives, others bows and arrows, and hand-to-hand infantry with pistols and waist knives, and carried rattan cards, and their common characteristic was that they were accustomed to walking mountain roads.

Even if only one-third of the battle was real, the rifle unit killed and wounded nearly 2,000 enemy soldiers.

The results of chronic bloodletting were comparable to a skirmish, and for Zhang Yunkai, this kind of combat mission was similar to hunting in the mountains when he was not in the army. After a long time, he even felt that the green battalion soldiers in the north were not as dangerous as the tigers.

In the early days of contact, the Green Battalion dared to rush over and counterattack after being ambushed by riflemen, but unfortunately the mountain looked at the mountain and ran dead, and the distance in a straight line was 1,200 steps, which was more than three or four times that of the mountain road.

The speed of the mountain infantry on the mountain road was much faster than that of the green battalion soldiers in the north, and the green battalion in Shanxi could not catch up. Waiting for the green battalion soldiers to crawl over, the ambush team scurried three and two on the mountain, and ran away early.

If the number of pursuers is small, the squad can even ambush again, and the hand-to-hand infantry they bring with them do this kind of work.

After a long time, the green battalion soldiers have also adapted, and their method of coping with it is very simple, they will not go too far out of the camp, and they will hold together when they leave the camp.

Chopping wood and cutting wood is a hundred people walking together, if you encounter an ambush, lie down as fast as possible, and never probe.

This did reduce casualties to a considerable extent, Zhang Yunkai went out on a mission in the early days, and was lucky to be able to kill 2,30 at a time, but now his record has dropped to single digits, which often makes Zhang Yunkai regret.

Zhang Yunkai didn't know that the most important thing about their combat operations was not how many green battalion soldiers were killed and wounded.

Killing a few more people is of course good, but more importantly, the Mountain Chasseurs greatly reduce the enemy's range of movement, reduce the frequency of enemy troops out of the camp, and damage the enemy's perception of the outside world.

Just like in the northern battlefield, the Tatars won most of the skirmishers and small-scale cavalry battles, forcing the Ming army to gather in groups, even if they were not deaf and blind, they became severely short-sighted.

In the first battle of Songjin, more than 100,000 troops did not find until Huang Taiji's reinforcements pressed to a day's distance from the battlefield, and the supply base was seized by the Tatars in just one night, cutting off the back road, so as to bomb the camp.

This is a ridiculous battle in the history of warfare.

Every time the Federal Military Academy took out the Battle of Songjin to give a lecture, the cadets would let out a burst of laughter while regretting it, laughing at the Ming army's-like suicide formation.

Of course, the Ming army did this for a reason, the battle of Salhu and the subsequent battle of Liaoshen, the Ming army dared to divide the army, but was broken by the Tatars, and then the Ming army always chose to find death in a group is a vicious circle.

It is never a mistake to deploy armies in a decentralized manner.

Yue Fei in Shaoxing's Northern Expedition, he was less than 100,000, maybe only 80,000, the infantry-based army, facing Wanyan Zongbi's 100,000 Jin army, of which about 30,000 iron cavalry, controlled the northwest to Luoyang, southeast to Taikang, zigzag, up to 300 kilometers of battle line on the Great Plains.

Yue Fei accurately predicted the direction of Yan Zongbi's main attack twice, and deployed his small number of mobile troops, on the one hand, of course, Yue Shuai was really a genius, and on the other hand, when facing a similar enemy, the Song army, which controlled the broad front, had much stronger perception than the Ming army.

The kind of thing that the main force of the enemy army did not know under the nose of the Ming army would never happen in Yue Fei's troops.

There were only a few decisive battles, and for the most part the army was in skirmishes, and it was not impossible for a force to be blinded and deaf by a peripheral war, but that required genius generals and unfortunate luck.

The area of the battlefield and the length of the battle line are often restricted by objective conditions, and the army's combat area is far more than a small area of the battle site, and the larger the battlefield under control, the stronger the perception, and the greater the possibility of gaining strategic superiority.

If you want to concentrate more troops on the main battlefield, you must control as large a battlefield as possible with as few troops as possible in the secondary battlefield.

It is true that the army can use the natural terrain, fortifications, natural climate, battlefield supply conditions, and many other factors to achieve this goal, but the most important thing is the tactical advantage that is reflected in skirmishes.

In the general terrain, ordinary Ming army squads were defeated by the Tatars, organized mountain warfare could close the gap, and the significance of the rifle troops was that the Ming army gained battlefield perception that they had never enjoyed.

The battlefield in front of Li Laiheng and Zhong Wenxin is almost transparent.

The main force of the enemy army was located in the slightly larger Yulin Basin, completely encircling Yulin City. The other basically surrounded the county seat of Bobai, but it could not completely cut off the connection between Bobai and the rear.

Around Yulin City, there is a hilly area with a relative drop of dozens of meters, which will not bring much obstacle to the army's action, and more importantly, the mountains around the Yulin Basin, the altitude is about a thousand meters, which is an insurmountable obstacle.

Mountain hunters rely on the mountains to attack the basin and reduce the enemy's range of movement. On the battlefield, it was true that the Tatars surrounded the Ming army in the city, but the Tatars knew almost nothing about the surrounding mountains.

Tianmen Pass is indeed the most important trade route of the south and north rivers, but the road is far more than Tianmen Pass, and Xu Xiake did not pass through Tianmen Pass when he traveled in this area.

The Ming army never held the Tianmen Pass, and neither did the Tatars.

The characteristics of mountain warfare are different from other battlefields. There are positions in the mountains, and they are very strong, and they should not be stormed.

The art of mountain warfare consists in taking positions from both flanks of the enemy, or from the rear of the enemy, forcing the enemy to advance and attack. If the enemy retreats without a fight, it can also achieve greater results through pursuit, and if the enemy retreats and builds a new position, repeat the above process.

Mountain warfare is not conducive to attack, and even in offensive warfare, the art of warfare consists in only defending and forcing the enemy to attack.

In other words, attacking at the campaign level, gaining a more powerful position, forcing the enemy to attack tactically, requires maneuvering.

The Tatar commander Ji Xiha is a general, the enemy's various camps are well connected with each other, the west flank extends to Xingye County through the valley, and Xunzhou is connected, the northeast flank passes through Tianmen Pass, and Beiliu County is connected, and the water transportation of the north and south rivers is the main military station line of Ji Xiha.

East flank?

Empty.

On the basis of this, the General Staff drew up a plan of operations.

According to the plan, while the Qiongzhou Brigade relieved the siege of Qinzhou, the battalion that remained in Lianzhou escorted the ship carrying baggage and heavy artillery to the Shahe Inspection Fort between Lianzhou and Bobai.

After the battle of Qinzhou, the main force caught up with the baggage troops, and then advanced to attack to give Bobai.

In Bobai, the Qiongzhou Brigade formed a detachment, with one infantry battalion as the backbone, reinforced one grenadier company and two mountain infantry companies, carried three pack-mounted light howitzers and three pack-loaded three-pounder guns, and maneuvered eastward along the valley of the Yashan River, a tributary of the Nanliujiang River, to Luchuan County, and then to the north, roughly along the Liumahe-Beiliujiang to the Beiliujiang River, cutting off the enemy's main military station line.
