Although the US Government immediately formally declared war on Mexico, for the time being it was only paying lip service and not taking action, because the Heavenly Punishment Column, which had not yet been wiped out, was still holding back a large number of US troops, and the US Government was in a hurry to draw up not many troops to resist the attack of the two Chinese Marine Divisions, and there were only two infantry divisions along the US-Mexico border for the time being, and it was very difficult to hold the North Bravo River, the boundary between the United States and Mexico, let alone cross the river and launch an attack on its own initiative.

Although the escort fleet and the convoy retreated to the Pacific Ocean after completing their mission, the ammunition supply they sent ashore was enough for two Marine Divisions to hold out for three months in the high-intensity fighting, and although food and other daily necessities were only enough to meet the needs of one month, it was not too much of a problem to buy from Mexico. What's more, with the superiority of the Marine Division's powerful combat strength and firepower, why would it take a month to break through the defensive line laid out by the US military on the north bank of the US-Mexico Boundary River?

Under normal circumstances, it is not easy to break through the river defense, during the Chinese War of Resistance in history, the devils have tried to cross the Yellow River to Yan'an many times, and at most dispatched no less than 15,000 troops (and this attack also occurred in 1939, when the combat effectiveness of the Japanese army did not decline significantly), but they were repelled by the Eighth Route Army left behind in northern Shaanxi, which is very revealing. With the combat effectiveness of the Japanese army at that time, in a normal offensive and defensive battle, even 100,000 or even 200,000 Eighth Route Army would not want to resist it head-on, but because of the natural danger of the Yellow River, it could be repelled by the cooperation of the remaining corps of the Eighth Route Army and the militia.

But there is also a problem with the defense along the river, that is, it must be fortified everywhere, it doesn't matter if the combat effectiveness of the troops is a little weaker, but the number must be enough, otherwise there will be loopholes everywhere, just like the ancient city, relying on the city, the defenders can often defeat the strength of several times, or even dozens of times their own strong enemies, but if the city is too big, the defenders are too few, then the city defense is almost like paper, sometimes it is even better to fight directly in the field, maybe the odds of victory can be higher, after all, the number is large, organization is a problem, It is not impossible to be routed in a field battle by a small but elite enemy force.

Therefore, the Eighth Route Army, which was historically weak in combat but had a large number of troops, could hold the Yellow River, while the U.S. Army, which was now weak in combat and had few troops, could not hold the North Bravo River defense line in any case. At this time, it coincided with the flooding of the North Bravo River, which caused many fortifications built by the US military to be submerged or even washed away, which objectively helped the Chinese marines. Yes, the flood devastated both banks, but China sent marines this time, and they were too good at fighting in this muddy field that resembles a shallow swamp......

After breaking through the North Bravo River, the remnants of the American troops on the defensive line had to retreat in panic, otherwise they would be surrounded and annihilated, but the Chinese troops crossing the river turned their originally organized retreat into a major rout through the "parallel pursuit" tactics, including the previous battle to defend the river, the number of American dead and missing more than 15,000, more than 30,000 captured, the two infantry divisions of more than 50,000 people only a few thousand escaped, and the number of casualties of the Chinese marines was only more than 1,000. Although there is a reason why the US Southern Front troops have not yet been reequipped, such a disparity in exchange ratio is enough to reflect the strength of the Chinese Marine Corps.

The two Marine Divisions all crossed the North Bravo River and took a break (by the way, the captured American troops and the captured captured ones were transferred to the Mexican army, which was another benefit of pulling the Mexicans into the group). He immediately marched north at full speed, capturing San Antonio, an important city in Texas, and then attacking west along the railroad line to the flank of the American army in El Paso.

El Paso is more than 1,000 miles from San Antonio, and the two Marine Divisions are fighting on the outside after penetrating deep into the United States, and they have to carry a large amount of baggage with them, which inevitably slows down the speed of the troops' march, and even if the road is not blocked by enemy troops, it will take more than half a month to arrive. Therefore, theoretically, if the US military makes full use of the militia to harass and block along the way, it is not hopeless that it will drag on until the end of the Battle of Pittsburgh, or at least close to the end, when the nearly 2 million US troops there will be free to divide their troops south, and the two Chinese Marine Divisions may have fallen into the dangerous situation of being attacked by the enemy before they reach El Paso.

But in fact, seeing the strength of more than 70,000 Chinese elite troops that are not inferior to the enemy in front of them approaching their flanks step by step, the US troops in El Paso inevitably panicked and wavered, although this force has been praised and rewarded by President Roosevelt many times in the past month or so, but in essence, the main component is either a rout, or a new recruit, the reason why it was able to stubbornly withstand the repeated attacks of the two Chinese mountain divisions is, on the one hand, the solid fortifications built in advance have played a role. On the other hand, the superiority of the artillery of the two mountain divisions was limited by the already extremely stretched supply lines.

In a few more months, by the time the former defeated U.S. forces in El Paso have fully regained their confidence and the new recruits have gained more experience, the force may become very strong. But for now, they are still very vulnerable, and in the face of the tremendous pressure brought about by the approaching more than 70,000 elite soldiers of the Chinese Marine Corps, if the group army headquarters does not do something, they are afraid that the morale of the troops will collapse, and the offensive of the Chinese army in the north is becoming weaker and weaker, which also brings greater confidence to the US army.

Even if the total strength of the troops sent exceeded 200,000, they did not dare to take the initiative to meet the 70,000 Chinese elite soldiers coming from the west, and their forward troops stopped after traveling about 100 kilometers eastward, and began to build fortifications on the spot, preparing to block the eastward advance of China's two major marine divisions here.

Even if they have not yet changed their outfits, at least some improvements have been made in tactics and fortifications, and the defensive battle north of El Paso has allowed these American troops to accumulate a lot of experience, and they have a threefold superiority in strength, even with the strength of the Chinese Marine Corps, it is impossible to complete a breakthrough in a short time under normal circumstances. But what the U.S. Army Command in El Paso didn't expect was that at the same time as the battle started in the east, the two Chinese mountain divisions north of El Paso also launched a fierce attack, and the intensity of the artillery bombardment was far greater than before, and they immediately realized that they had been tricked, it turned out that their offensive was getting weaker and weaker in the past two months was just a deception, just to make their own side mistakenly think that their supplies could not keep up, and when they had enough ammunition, they suddenly launched a fierce attack to catch themselves off guard......
