"Tanks! My God! The tanks of the Chinese are coming! An American soldier shouted in horror as he looked at the anti-tank trenches in front of the positions and the tanks that were heading for the American positions.

"Sons of bitches, guys who operate anti-tank guns, why don't you destroy these tanks!" A second lieutenant platoon commander scolded. As a veteran of the Battle of Mexico's Central Defense Line, he knew what the consequences would be if he was rushed up by Chinese tanks. With their flesh and blood alone, they can't resist these steel monsters at all.

"Da Da Da!" A heavy machine-gun fire point on the U.S. line, densely fired at a TP

'Wolves, light tank strafing. The bullet hit the steel plate of the tank with a crisp sound. However, there was no effect other than leaving a little white mark on the steel plate of the tank. Even a light tank can withstand close fire from heavy machine guns

"Crunch!" This TP' wolf, a light tank, seemed to be angered by the behavior of the American army with its mantis arm as a car, and turned the head of the car and pressed directly towards this firing point. Soon, the tank drove in front of this point of fire and pressed directly from above. The American soldier who operated the heavy machine gun had no time to dodge, and was directly run over by the tank's tracks, leaving a bloody mark on the ground.

"Boom!" Tanks that rushed to the positions of the Americans began to destroy machine gun fire points, as well as mortar and mountain artillery positions on the positions of the Americans with tank guns. At the same time, the machine guns on the tanks also opened fire on the scattered and fleeing American troops, wantonly harvesting their lives.

"Devil! You yellow-skinned monkeys are devils, I'm going to kill you! "A young soldier of the American army, holding a bundle of grenades, rushed towards a TP'wolf, light tank a few meters away. After the grenade pulled the string, it was thrown directly onto the tracks of the tank.

"Boom!" After the explosion, the tank's tracks were blown off. This TP' wolf, the light tank suddenly lost its ability to move.

“***！ Infantry, we need the protection of infantry! The commander of the 2nd Battalion of the 3rd Armored Brigade of the Chinese Army roared loudly. Although the tank has a rough skin and thick flesh, it also has vulnerable points, such as the tracks and the exhaust vents of the engine behind it. If it is not protected by infantry, it will become the target of the enemy's main attack.

Fortunately, the infantry who followed the tanks soon also crossed the anti-tank trenches of the American army and fought behind the tanks. On the one hand, under the protection of the tank, the American soldiers on the position were cleared, and on the other hand, the tank was provided with close protection.

A few brave American soldiers, trying to blow up the Chinese tank, rushed towards a TP' wolf, a light tank, carrying explosives packs. However, most of them were killed by machine guns from the tank before they could get close to the tank, and the remaining two were shot by the Chinese infantry behind them just as they were about to rush to the tank's side.

"Commander, breakthrough! We have already broken through the defenses of the Americans! Major General Fan Zhihua, commander of the Armored Brigade of the 2nd Group Army of the Chinese Army, said excitedly that at this moment, he no longer had the decadence of yesterday. Although his armored brigade suffered heavy losses in this battle, they have found a set of effective methods for dealing with the anti-tank tactics of the US army, which will also be of great help to the US army in future operations.

"Well, I knew the armored forces wouldn't let me down. Order the 14th Infantry Division to start the attack, break through the American lines, and drive them to San Luis Potosí! The commander of the 2nd Army, General Xie Dingkun, ordered. Yesterday's crushing defeat of the Panzer Corps dealt a big blow to the entire 2nd Army, and now it has finally regained its morale.

The 14th Infantry Division of the 2nd Army was already ready, and immediately after the order was given, it followed the passage opened by the armored brigade in the American defense line, attacked the American defense line, and with the cooperation of the tanks and armored vehicles of the armored brigade, began to widen the gap and clear the American troops on the position. Subsequently, the 2nd Army continued to increase its investment, sending two other infantry divisions to participate in the attack. Ten divisions were also drawn from the Japanese mercenaries and thrown into the attack.

Although, on the defense line of the US army, there are still more than 200,000 US soldiers. But after the anti-tank defense line in front was broken through, the American troops in the rear no longer had the confidence to continue fighting. The rifles and machine guns they wield were no threat to the tanks and armored vehicles, which were capable of slaughtering them at will. Such a scene has made many US officers and men feel deep helplessness in their hearts.

The difference in strength between the two sides is too big, which makes them powerless to fight back at all!

"Kill! Kill all the Yankees! Groups of Japanese mercenary soldiers, with small thick legs, quickly rushed towards the position of the American army

"Da Da Da!" A platoon of machine-gun bullets hit, and the Japanese mercenary soldiers who rushed to the front were already shot and fell to the ground. But then, an armored vehicle more than two hundred meters behind immediately opened fire, suppressing this heavy machine-gun fire point. The remaining Japanese mercenary soldiers also took the opportunity to break into the trenches of the American army, and they began to engage in brutal white-knuckle combat with the American troops in the trenches, armed with rifles with bayonets. Although the Japanese mercenary soldiers were short in stature, they were very strong, and they were highly skilled in white-knuckle warfare, and the American soldiers in the trenches they killed kept retreating. Frequently, American soldiers were stabbed and fell to the trenches screaming

As more and more squadrons and Japanese mercenaries invaded the positions of the US military, a large number of loopholes began to appear in the defense line that the US military had painstakingly built. The squadron and the Japanese mercenaries, with the cooperation of tanks and armored vehicles of the armored forces, cleared the American soldiers on the positions. After the anti-tank units of the US army were eliminated, the remaining US troops were completely unable to resist the attack of the squadron, and it was inevitable that the entire defense line would be broken through.

"General, it's no longer safe here, our position has been broken through by the Chinese, we must go back to San Luis Potosí immediately!" Lieutenant General Cole said nervously. Yesterday, they also saw the hope of victory, and the goddess of victory seemed to have lifted her skirt against them. But now, everything has become empty talk, and the anti-tank units on which they had high hopes have been almost completely wiped out under the blows of the Chinese armored forces and air force, which has shattered their hopes of holding their positions.

"Order the heavy artillery units to withdraw to San Luis Potosí first! The rest of the troops, try to resist the Chinese, wait until after nightfall and then withdraw to San Luis Potosí! Admiral Davis said. The situation was very critical now, and he knew that it was only a matter of time before the entire defense line was breached. Although he wants to hold on and keep the Chinese at bay in northern Mexico, it now seems unlikely.

"Yes, General! However, now that the defense line has been breached, the Chinese will launch an attack on San Luis Potosi tomorrow at the latest! Are we retreating, or are we holding on to San Luis Potosí? Lieutenant General Cole asked. In terms of equipment and strength, the US military is greatly inferior to the squadron. Now the only anti-tank units on which they relied have also been eliminated, and in the opinion of Lieutenant General Cole, they have already failed, and an early retreat is the king.

"It's not like we can retreat if we want to, we have to ask the country. Without the orders of the Minister of War and the Chief of Staff of the Army, if we retreat without permission, I am afraid that we will be court-martialed! Admiral Davis shook his head with a wry smile. At present, the defense line of the Rio Grande in the north has not yet been fully completed, and a large number of anti-tank weapons are still being deployed. Both the U.S. War Department and the Army Staff must have hoped that they would be able to buy more time for Admiral Pershing. As for their lives and deaths, it is estimated that no one will care. In the eyes of those big people in China, they are just tools, and as long as they can withstand the attack of the Chinese in the end, it is completely worth sacrificing them. Of course, both Admiral Davis and Lieutenant General Cole belong to the senior generals of the U.S. Army, and their lives will certainly be saved at the last critical moment. As for the rest of the ordinary soldiers, it is estimated that they can only pray for God's blessing!

Admiral Davis and Lieutenant General Cole returned to San Luis Potosí from the front headquarters, while reporting the upheaval found at the front to the country, asking for permission to retreat. On the other hand, the defense of San Luis Potosí was deployed. During these months, the U.S. military has been strengthening the defenses of San Luis Potosí, and although it has not been built into a fortress, various fortifications have been densely packed into the city, and it is not much different from a fortress.

The squadron's attack on the U.S. defense line continued, and the U.S. army's will to resist gradually weakened as casualties continued to increase.

Watching the comrades-in-arms around him continue to be killed, even if the willed person is strong, he will not be able to hold on.

"Oh God! I don't want to die here, I want to go home! "A young soldier of seventeen or eighteen years old, throwing away his rifle, turned around and crawled out of the trench and fled backwards.

"Smack!" A rifle shot rang out, and the young soldier fell headlong to the ground. It was a Chinese soldier who shot it! On the battlefield, there will be no mercy, even if he is still a minor, but as long as he puts on a military uniform and picks up a weapon, then he is a soldier, that is, the enemy of the squadron, except for surrendering, there is only one way to be killed.

By 12 noon, with huge casualties, the American troops began to abandon their positions on the front line and retreat towards San Luis Potosí.
