He repaired with Liu Pu's Chinese troops and the Chinese Independence Army for one day, and launched a tentative attack on La Paz the next day.

La Paz is located on a high ground at an altitude of 3,640 meters, and El Alto, not far from La Paz to the north of the city, is a satellite city of La Paz. From El Alto, you can get a bird's-eye view of the entire city of La Paz.

El Alto was an important stronghold for the defense of La Paz, and after Melgarejo's order was issued, Balivian reinforced the defense of El Alto, and when the Chinese Independence Army began to attack, El Alto had 5,000 defenders, only 3,000 fewer than the defenders of La Paz.

Under the city of El Alto, the Bolivian defenders set up three lines of defense on the mountainside, preparing to take advantage of the steep terrain of the Real Mountains to block the attack of the Chinese Independence Army.

The first line of defense was 400 meters from the front of the Chinese position at the foot of the mountain, and the Bolivians placed about 500 soldiers on this line.

The mountains of Real were steep and long, and the high elevation angle was not conducive to attacking the mountain positions with heavy artillery, and the Chinese Independence Army could only order its soldiers to climb and attack if they wanted to capture the enemy's defensive line.

At the foot of the mountain, a platoon of more than 700 Chinese soldiers was ready, and under the leadership of the leading officer, they scattered and launched an attack on the mountain.

When the Chinese soldiers approached a distance of 100 meters from the first line of defense with their shields in hand, the Bolivian defenders began to attack with small artillery, firing from top to bottom, and the roaring shells continued to sound around the Chinese soldiers, and five or six Chinese soldiers were unfortunately hit by the shells and died in the first round of the attack.

The regimental commander hid behind a rock, ordered his soldiers to find cover, and when the shelling was over, the Chinese soldiers continued to climb and advance.

The attacking Chinese soldiers were armed with Dresser rifles with a range of 600 meters, but at a distance of 100 meters, the shooting accuracy was very poor, so in the face of the artillery fire of the Bolivian soldiers, the Chinese soldiers did not return fire with rifles in their hands.

The overall quality of the Bolivian soldiers was not as good as that of the Peruvian army, let alone the soldiers of the Chinese Independent Army.

It takes a certain time interval for the artillery to fire ammunition, and the continuous shelling caused the cannon body to overheat, and the four guns exploded one after another, injuring a dozen Bolivian soldiers next to the artillery.

Four guns exploded in succession, and the barrel of the guns was overheated, and the Bolivian defenders had to stop shelling. At this time, the Chinese troops advanced almost fifty meters, and they were still more than fifty meters away from the Bolivian position.

The attacking Chinese soldiers encountered a problem at this time, the mountain road in front of them suddenly broke off, and a steep straight hill of nearly two meters blocked between the Chinese soldiers and the Bolivian troops.

There was no way to go on both sides, so the regimental commander gritted his teeth and sent more than a dozen soldiers to climb up, but as soon as the Chinese soldiers climbed the steep slope, they were fired at intensively by the Bolivian soldiers, and the thirteen soldiers who climbed up were killed and wounded eight in an instant. The other five soldiers saw that the situation was not right, and jumped down in time to avoid ending up like them.

"Commander, it's flat above, there's no shelter, and the brothers become live targets for the Bolivians as soon as they show their heads." The Chinese soldier who jumped off reported.

After listening to the soldiers' reports, the Chinese regimental commander observed the terrain above from the side, and said: "Brothers, the terrain above is open, as long as we cross this steep slope, we can kill the enemy. ”

The enemy's defense line was close at hand, and the officer leading the team did not want to give up the opportunity of more than 30 Chinese soldiers who were killed and wounded, and encouraged.

Li Mingyuan and a group of high-ranking Chinese Independence Army officials watched the battle below, and the attacking Chinese soldiers did not want to embarrass the troops, so they continued to attack with vigor.

The steep slope is difficult to climb, and as just now, one soldier climbs upwards one soldier after another, which is not only easy to cause huge casualties, but also difficult to capture the enemy's position, so the officer leading the team, under the advice of the staff officer, cut down the small trees on the mountain to build a simple inclined plank, and then step on the inclined plank to attack forward.

With the help of the inclined planks, the Chinese soldiers quickly climbed the steep slope and withstood the fire of the Bolivian soldiers, and the Chinese soldiers continued to climb the steep slope, and within a few minutes, the number of Chinese soldiers on the steep slope reached more than 100. The machine-gun platoon purchased and built a position on the spot to cover the attack of the soldiers.

The leading officer stepped up the steep slope and commanded loudly.

Five machine guns were quickly erected on the ground, next to each machine gun two soldiers placed ammunition, and one machine gunner aimed and ready to fire.

"Da-da-da-da," five Gatling guns fired five lines of fire, and the ammunition casings landed on the ground with a clanging sound.

Five machine guns suppressed the fire of the Bolivians to a limited extent,

The advancing Chinese soldiers advanced to within 20 meters of the Bolivian position, and "boomed" one of the Chinese soldiers threw away the grenade on his waist and eliminated the three Bolivian soldiers in front.

In close combat, the superiority of the soldiers of the Chinese Independence Army was revealed, grenades, bayonets constantly harvested the lives of Bolivian soldiers. Finally breaking down the Bolivian lines, many Bolivian soldiers ran out of their positions and ran towards the mountains.

The Chinese officer who led the team divided half of the soldiers to besiege the Bolivian soldiers in the defense line, and personally led more than 300 Chinese soldiers to pursue the fleeing Bolivian soldiers, hoping to break through the second line of defense of the Bolivians in one fell swoop.

There were more than 100 Bolivian soldiers who fled, and under the pursuit of the Chinese soldiers, they desperately ran towards the second line of defense set up by their side.

After a distance of two hundred meters, more than half of the fleeing Bolivian soldiers were killed, and only more than thirty soldiers were left running desperately.

The Chinese officers who led the team pursued too fast, and they had already run to the front of the pursuing soldiers, and they were only more than 30 meters away from the Bolivian deserters.

The leading officer shot a Bolivian soldier, and at this time, the chirping sound of artillery shells was heard in his ears, and without thinking too much, the Chinese officer leading the team quickly fell to the ground, and then a cannonball fell less than five meters away from him.

As the first shell landed, dozens of shells landed in the ranks of the pursuing Chinese soldiers within a minute, and more than 500 muskets were fired from behind the cover boulder cover.

The smoke of the shells shrouded the pursuing Chinese soldiers, and the pursuing Chinese soldiers suffered heavy casualties, and many of the Chinese soldiers who were quickly pursuing were directly hit by the ammunition and fell to the ground.

"Back off, all back off."

Realizing that he had been ambushed by the Bolivians, the Chinese officer who led the team stood up and shouted loudly, regardless of his safety.

The Chinese officer who led the team was at the forefront of the Bolivian shooting, and his shouting attracted a large number of bullets from the Bolivians, resulting in more than a dozen bullets in his body, becoming the highest officer to die since the uprising of the Chinese Independence Army.

Witnessing the death of the Supreme Commander, many Chinese soldiers stepped forward to snatch back the body of the commander, but not only failed to get the body back, but lost their own lives.

The situation was grim, and after the Chinese regiment commander who led the team was killed, a battalion commander of the pursuing unit took over the command of the unit and gave the order to retreat.

In the ambush battle in front of the second line of defense, more than 300 Chinese soldiers only withdrew more than 80 people, including the regiment commander, more than 240 Chinese soldiers remained in front of the position, except for a small number of prisoners, the vast majority of Chinese soldiers were killed on the spot, and this battle also became the first crushing defeat suffered by the Chinese Independence Army.
