"Dear Elihu. His Excellency Minister Root, Leonard. General Wood! The situation in Mexico has completely eroded, and we can no longer resist the attack of the Chinese. In the whole San Luis Potosí and nearby areas, the Chinese have an absolute advantage. Our soldiers, all the time, are subjected to shelling by the Chinese and bombarded by aircraft, and every second lives are lost. There's no hope in sight here! For the sake of the lives of most people, in order to be able to preserve our strength, to be able to continue fighting. I implore the War Department and the Army Staff to agree to our breakout plan and to retain as many elite soldiers as possible for the United States so that they can play a more important role in resisting the Chinese invasion in the future. After all, the Chinese are too strong, and our war with the Chinese will be a protracted war that will not end so easily. Save more seeds, and we will have more strength to hold on in future wars. Therefore, I have decided to retreat eastward with my army this evening, over the Sierra Madre Oriental, to the Gulf Coast.

I hope the Navy will send a fleet to meet us! "At five o'clock in the morning of August 30, the commander of the U.S. forces in Mexico, Admiral Davis, sent a telegram to the War Department and the Army General Staff that he had personally drafted, and now he had made up his mind to retreat. In fact, after the telegram was sent, he and Lieutenant General Cole withdrew from San Luis Potosí with some henchmen and slipped away from the Sierra Madre Oriental, to the east. And the troops below, receiving orders to hold out until the evening, and then retreat in batches.

The U.S. War Department and Army Staff, after receiving a telegram from Admiral Davis, had no choice. They have also learned that the battle of San Luis Potosí was fought very hard by the American army. After the squadron dispatched armored troops to assist the infantry in clearing the US troops in the city, the US troops could not resist the attack of the squadron at all, and blindly routed. It can be seen from this situation that the US military will not be able to hold out for long. Therefore, Admiral Davis demanded a retreat, and there was nothing they could do to stop it. They knew that even if they ordered Admiral Davis to continue to persevere, Admiral Davis would definitely not do it. Therefore, they can only ask Admiral Davis to bring these Americans back to the United States safely as much as possible. After all, these soldiers have had the experience of fighting with the squadron, although they have lost the battle, but after the battlefield test, their combat quality is much higher than that of those rookies who have just come out of the recruit camp. As long as they are re-equipped with new weapons and restored their combat strength, they will definitely be able to become the main force of all troops. As Admiral Davis said, this war between the United States and China will be a protracted war, and they must preserve their strength as much as possible.

Twenty kilometers east of San Luis Potosí is Sierra Madre Oriental. When the U.S. forces occupied San Luis Potosí, their fortifications stretched from San Luis Potosí to Sierra Madre Oriental. It's just that the fortifications here can't be compared to the inside of the city. The squadron also regarded San Luis Potosí as the main target of attack, and did not attack this section of the US defense line for the time being.

Most of the Sierra Madre Oriental, with an altitude of more than 2,000 meters, and the traffic facilities are very poor, there are no regular roads, only some small roads. If the US military wants to break through from this direction, it will have to abandon all heavy equipment. Moreover, it is completely impossible for hundreds of thousands of American troops to retreat through the path in the Guò mountains. Therefore, the squadron did not send troops to intercept the US troops from this aspect. And this undoubtedly gave them a chance to retreat. It's just that even if this is the case, most of the U.S. troops will not be able to withdraw.

At seven o'clock in the morning of August 30, the artillery brigade of the 8th Army of the Chinese Army and the artillery battalions of various infantry divisions began shelling San Luis Potosí. Only a small part of the city area now occupied by the US military remains. It is expected that after today's battle, the squadron will be able to completely occupy San Luis Potosí. When the time comes, the armored forces will attack to the east, and they will be able to annihilate the main force of the US army with ease and successfully complete this battle. And the time it took will definitely not exceed the deadline given by Marshal Zhao Bowen within a week.

Because the urban area controlled by the US military is no longer very large, a large number of US troops have gathered here, and the heavy artillery units of the Chinese Army can almost achieve a lot of gains with every shell exploding.

"Buzz!" It was as if a large swarm of wasps were flying, and when this sound came, the American soldiers in San Luis Potosi looked at the sky in horror. After these days of fighting, they already understand what it sounds like.

Hundreds of Chinese Air Force fighters appeared in the skies over San Luis Potosí and began to drop bombs on the US military. Dense bombs exploded on the positions of the American troops, turning them into a sea of fire.

At 8 o'clock in the morning, it was already ready! An infantry division of the 8th Army and two divisions of the Japanese mercenaries, assisted by the 8th Armored Brigade, launched an attack on the last area of the American army. The morale of the soldiers was high, and the continuous advance over the past few days convinced them that they were about to defeat the Americans.

"General He, I think we will be able to take San Luis Potosi within today. After that, northern Mexico will be unsafe. We can fight all the way north to the Rio Grande. If you cross the Rio Grande, you're in the United States! "said the commander of the Japanese mercenaries, General Yoshimasa Oshima. For the United States, he has been looking forward to it for a long time. Mexico is a poor country, with no oil or water at all, not even the South Seas. In the more than half a year that the Japanese mercenaries have been fighting in Mexico, they have not gained anything at all. But the United States is different, the United States is a very rich country, once it invades the United States, with the means of Japanese mercenaries, it will definitely be able to obtain huge gains!

"Haha! There is no longer any problem in defeating the American army and recovering Mexico. However, it is not so easy to cross the Rio Grande and attack the territory of the United States! The Americans put all the main forces there! Admiral He Bingju said. It is no secret that the U.S. military is building the Rio Grande defense line, which is no secret to the squadron. It's just that in the past year's war, the U.S. military has built a lot of defensive lines, but every time it has been broken through by the squadron. This time, the Rio Grande defense line should also end in the same way.

"General He, no matter how strong the Americans' defense line is, it will definitely not be able to withstand the Chinese tanks and planes, and I believe that we can easily attack the United States when the time comes!" Senior General Yoshimasa Oshima said. So far in the war, the squadron has occasionally encountered some setbacks on the battlefield, but on the whole, it is still making great progress. This also made the officers and soldiers of the mercenaries such as General Yoshimasa Oshima full of admiration for China. They firmly believe that the war will definitely end with a Chinese victory. And they, the Japanese, can also take advantage of China's footsteps. After all, China eats meat, and those of them who are little brothers can always drink some soup!

"I'm also looking forward to the day when we make our way into the U.S. mainland. I believe that day will not be too far away! Admiral He Bingju said.

On this day of fighting, the resistance of the American army was very weak. By noon, after several hours of fighting, the 8th Army and the Japanese mercenaries had taken the whole of San Luis Potosí. The U.S. troops stationed here either fled or surrendered directly to the squadron. The morale of the US military was low, and it no longer had the courage to continue fighting.

Marshal Zhao Bowen, Minister of the Chinese Army, Supreme Commander of the Mexican Front, also personally rushed to the front after learning of the capture of San Luis Potosí. He was satisfied that the 8th Army was able to capture San Luis Potosi at a relatively small cost and destroy numerous enemies.

"Marshal, the resistance of the Americans is not fierce, the 8th Army and the Japanese mercenaries have already launched an attack on the last line of defense of the American army. This time, it will be difficult for the US military to fly with wings! Admiral He Bingju said.

"Hmmm! Let the 8th Army guard the gap in the north and don't let the Americans run away! Marshal Zhao Bowen said. After the total annihilation of this American army, the entire Mexican battlefield has already been decided.

At this time, a staff officer hurriedly walked into the headquarters.

"Marshal, news has come from the Air Force that reconnaissance planes over the Sierra Madre Oriental have spotted a large number of American troops fleeing eastward!" said the staff officer. Originally, Admiral Davis's order was to hold on to retreat until the evening, but because of the unsmooth situation of the battle, and Admiral Davis and Lieutenant General Cole had already fled first. Therefore, the commanders below also did not care about carrying out the order to hold on until the evening, and directly led the army to escape!

"East? Sierra Madre Oriental? How is this possible? Admiral He Bingju was taken aback.

"Order the troops, attack immediately! Eat the main force of the Americans! Marshal Zhao Bowen gave the order directly. Although it is known that it is impossible for the main force of the US army to cross the Sierra Madre Oriental, it is better to attack immediately in order to avoid long nights and dreams.

After Marshal Zhao Bowen gave the order, the main force of the 8th Army and the main force of the Japanese mercenaries launched a fierce attack on the US army, and there were no longer any reservations. Under such a blow, the US military, which was already panicked, could not hold on at all and surrendered to the squadron one after another. By evening, most of the fighting was over. The main force of the U.S. military on the battlefield in Mexico has been basically annihilated, and this also indicates that almost a year after the war between China and the United States, China has once again recovered Mexico!
