On the Querétaro front, the main forces of the eight armies of the US army had been assembled here, and under the personal command of Lieutenant General Pershing, a fierce attack was launched on the squadron and the positions held by the Mexican government forces. The defense line of the Sino-Mexican coalition forces in Querétaro relied on the hills on both sides of Querétaro to build seven lines of defense about 100 kilometers long. The central flat area, where Querétaro is located, is the most important part of the defensive line. The main force of the Chinese Army's Sixth Army was also stationed here, while the rest of the defensive line was defended by Mexican government forces.

The attack of the American army was very fierce, and Lieutenant General Pershing seemed to want to be ashamed, completely abandoned attacking the positions defended by the Mexican government army, and placed the main target of the attack on Querétaro, which was defended by the Chinese army.

"Boom! Rumble! Rumble! "The sound of violent explosions filled the entire battlefield, and the eight armies of the US army, which had assembled thousands of artillery pieces, launched a fierce artillery bombardment of the positions garrisoned by the Chinese army. At this time, the Sixth Army had only more than 300 heavy guns, and it was completely inferior in numbers. Fortunately, the 155mm heavy howitzer and the 155mm heavy cannon have a long range and can be deployed outside the range of the US artillery to fire, so that the artillery of the Chinese Army is not completely suppressed by the US army. But even so, the Chinese Army fought very hard.

The US military has absolute superiority in troops, and it has launched large-scale offensives since yesterday afternoon, and each time the attacking force is more than one division. Even though a thick layer of corpses had been piled up in front of the Chinese army's position, the Americans did not seem to be deterred by this, and still launched a fierce attack. It's as if the roots didn't take the lives of ordinary soldiers seriously!

This made the casualties of the US troops very large, and after yesterday's day of fighting, the US troops dropped at least tens of thousands of corpses in front of the positions of the Chinese army, and in the absence of artillery superiority, the Chinese army also paid a regiment of casualties. A large part of the casualties were killed by shells while resisting the attack of the American army! The situation is very unfavorable for the Sixth Army of the Chinese Army!

"Commander, the 68th Division is about to be unable to hold on, and the attacks of the Americans, regardless of casualties, have inflicted great casualties on them, and the casualties of the entire division have reached 40 percent. If the fight continues, this division will suffer heavy losses! Lieutenant General Yang Ming, Chief of Staff, said.

"Let them hold on a little longer! In the afternoon, the 12th Division will go up and withdraw them to rest and recuperate! General Gao Chang, commander of the Sixth Army, also said with a calm face. The intensity of the U.S. military's attack also exceeded his expectations.

"Commander, why don't we continue to retreat! The General Staff and the War Department gave us the request. Let's just guarantee a port city in Mexico. The reinforcements of the Seventh Army will be able to land in about ten days, and there is no need for us to fight the Americans here! Lieutenant General Yang Ming built yì road. The current shape is that the enemy is outnumbered, and if it fights, it will be very disadvantageous to the Sixth Army!

Admiral Gao Chang nodded, and then said, "My original plan was to prepare to resist the American troops here for a week, and then withdraw to Mexico City. Relying on the defense of Mexico City, it was not difficult to hold out until reinforcements arrived. But. The intensity of the U.S. attack exceeded my expectations, and I am afraid that even if I retreat to Mexico City, it will be difficult to reach the U.S. attack. And to abandon Mexico City would be a huge blow to our prestige in Mexico. Mexicans who have already wavered when they come. I'm afraid it will give birth to two hearts! "Admiral Gao Chang didn't know that the Madero government had fallen to the United States and sold them!

"Commander, if that happens. We can't stop it. What we can do is preserve our strength as much as possible. If the Mexicans really betrayed us. When our reinforcements arrive, we can naturally pack them up lightly! Lieutenant General Yang Ming said.

"Hold on for two more days, and in two days we'll be back to Mexico City!" Admiral Gao Chang said.

On September 29, the fierce fighting ceased after the sun had set. The exhausted Chinese and American armies stopped fighting and began to lick their wounds. In today's fierce fighting, the US troops left tens of thousands of corpses in front of the positions of the Sixth Army, and the losses of the Sixth Army were not small. In particular, the 68th Division lost nearly half of its losses in the continuous fighting.

Fifty kilometers west of Querétaro, there is a small town called Cortázar. This is an important node of the Sino-Mexican coalition forces on the Querétaro Line. The troops deployed here are mainly two divisions of the Mexican government army, and the cavalry brigade of the Chinese Army's Sixth Army is also able to support them in an hour. However, after the American army began to attack, it did not attack here, but put the main target of the attack on the squadron that held Querétaro. This made the Mexican government soldiers stationed here cry out for joy.

In the evening, Major General Carter, commander of the 12th Division of the Mexican Government Army, received a secret telegram from Mexico City, and after personally translating the contents of the telegram, Major General Carter could not calm down for a long time. This telegram was sent to him by President Madero himself, asking him to open a hole in the position in the middle of the night this evening, so that the US troops can easily penetrate their defensive line. This made Major General Carter very difficult.

Many of the generals of the Mexican government army came from the peasant rebel army that opposed the Díaz government or the army that Madero had formed with the support of the Mexican bourgeoisie. Major General Carter was once a subordinate of Madero, and he is still related to Madero. He and President Madero are cousins, but very few people know about it. In order to have a pawn in the army, Madero never exposed the relationship between them. And now, this relationship can finally be used!

Major General Carter's own ideas were pro-Chinese, but he could not refuse Madero's request. Moreover, Madero was able to send him such a telegram, and it was clear that Madero had betrayed China. If he does not carry out Madero's orders, his family in Mexico City will be murdered. In addition, he was somewhat dissatisfied with the Chinese side's treatment of Mexico as a colony!

After thinking quietly for an hour, Major General Carter made up his mind.

"I hope my cousin's decision is the right one! Otherwise, the whole family will be doomed! Major General Carter said secretly.

On the night of September 29, the 12th Division of the Mexican Government Army completed a change of defense on the defensive line, and the 1st Regiment, the henchman of the division commander, Major General Carter, replaced the troops in the previous garrison. This did not arouse suspicion among others.

At 12 o'clock in the evening, a bonfire was lit on the line of the 12th Division. In less than ten minutes, a dense crowd emerged in front of the 12th Division's defensive line. A large number of American soldiers crossed the line of the 12th Division and entered Cortázar. While the U.S. forces were fighting fiercely with the squadron in Querétaro, Major General Pershing had already ordered the 11th and 13th armies of the U.S. army to secretly go to the front of Cortázar. After the 12th Division of the Mexican Government Army released the defensive line, the American troops of these two armies quickly passed through the defensive line and launched an attack on the other Mexican government troops stationed in Cartazar!

"Boom! Rumble! Rumble! Da-da-da-da! "Dense gunfire rang out in the town. U.S. forces launched a fierce assault on the barracks of the Mexican government forces. And the Mexican government army, which was hit suddenly, did not have any convenience, and was completely stunned by the surprise attack of the US army!

"General, the Americans have come in, the town is full of Americans, and our people are almost overwhelmed!" A junior officer stormed the headquarters and reported to the division commander of another Mexican government army stationed in Catazar.

"What's going on? How could the Americans suddenly attack? The teacher was shocked.

"It's the people of the 12th Division, they let the Americans in!"

"Damn, what is that Carter guy doing, he can't take the Americans? Hurry up and send a telegram to General Gao! The division commander immediately ordered.

The two armies of the U.S. army, with nearly 100,000 troops, dealt with two divisions of the Mexican government army, and one of the divisions also became the internal response of the U.S. army.

After that, the U.S. 11th and 13th armies, leaving a small number of troops to defend Cortázar, and the main forces advanced eastward. For a moment, the entire line of defense was eroded!

It was only an hour after the American troops took Cortázar that the Sixth Army command received the news. Lieutenant General Yang Ming, chief of staff, hurriedly woke up General Gao Chang, commander of the group army, who had already rested.

"Commander, something is wrong, the 12th Division of the Mexican government army has mutinied, and the Americans have taken Cortázar and are marching east overnight. The Mexican government troops deployed on the defensive line could not resist the attack of the Americans at all, and many Mexican government troops surrendered directly to the Americans, what should we do now? Lieutenant General Yang Ming said with some panic.

"Holy shit, how could such a thing happen, and those Mexicans dare to betray us?" Admiral Gao Chang was also completely stunned by this news!

"General, shall we order the cavalry brigade to launch an offensive and try to repel the attack of the Americans?" Lieutenant General Yang Ming built yì road.

Admiral Gao Chang shook his head, and then said: "It seems that the Americans have been planning for a long time, and they deliberately stormed Queretaro just to attract our attention and then break through from Cottsal. At this moment, the entire defense line was shaken, and there was no longer any possibility to hold the defense line! ”
