The team will enter the Atlantic Ocean through the Dominica Strait between Dominica and Guadeloupe, and then make a detour north to the southeastern waters of the Bahamas, where it will wait for an opportunity and eventually a decisive battle with the Atlantic Fleet.

Huang Xiaotian also completed the alternate campaign plan on this day. If the Atlantic Fleet does not come to the decisive battle, in mid-June, the First and Third Fleets will return to the Caribbean Sea in the Strait of Silver Shoal, as well as the Windward Strait, and bomb and shell American military bases and ports in Cuba and Haiti along the way. After the final passage through the Jamaica Channel, the covering fleet first attacked the island of Jamaica and then supported the fleet's attack on Cuba.

These two sets of battle plans are not complicated, and both planners strive to be simple in the main direction of action, so that they can have more room to play tactically; if the main plan is too complicated, then the fleet will be more restricted when it moves, and it will be difficult to play well in tactics. But there is a problem in both plans, that is, is it appropriate to take action?

At that time, neither Tan Renhao nor Huang Xiaotian had determined the start time of the campaign, because they both lacked a condition that could allow the campaign to start smoothly and at the same time allow the campaign to be victorious. In other words, the lack of a necessary event to lead the whole campaign.

As for the Marine Corps, Han Shaofeng only set a deadline for attacking Jamaica, that is, June 15, with a maximum delay of five days. That is, before June 20, the Marines must land on the island of Jamaica and launch an offensive against the Greater Andrés Islands. In addition to mobilizing the landing fleet, loading the transport fleet with war materials and preparing for departure, and dispatching shore-based aviation units to bomb US airfields and ports on Cuba and other islands. Han Shaofeng will wait for the results of the fleet's actions. But this only set the deadlines for the combat operations of the fleet, and did not determine the time of their start.

At that time, Tan Renhao and Huang Xiaotian both knew that if the fleet took the initiative to attack, Spruance would definitely guess their intentions and would not be easily fooled. Won't even leave Norfolk Military Port. Then, Tan Renhao and they have no chance to take out the Atlantic Fleet at all. Therefore, there had to be a reason for the fleet to leave the Gulf of Limon and officially leave for the front. Just when the two were worried about this issue, Gu Xunlei, who was far away in Gutierrez commanding the army expeditionary force, sent a "big gift".

The news of the Army Expeditionary Force was delivered on June 6, and after more than a month of planning and preparation, Gu Xunlei gained enough strength to launch a second campaign on Puebla, which was also the second large-scale offensive launched by the Army Expeditionary Force on the battlefield in Mexico at that time.

After the end of the first battle, Gu Xunlei asked the army headquarters for more troops and supplies. He also made more preparations for the second campaign.

Through the first battle, Gu Xunlei has already realized. It would not have been possible to quickly recover all of Mexico by relying on the Imperial Expeditionary Force alone, despite the poor quality of the officers and men of the Mexican government army. The combat effectiveness is even worse, but in non-major theaters, the role of the Mexican government army is still quite enormous. For example, the Mexican government army could be responsible for the logistics of the Imperial Expeditionary Force, at least the Mexican military personnel are more familiar with Mexico's geography and transportation. In addition, the Mexican government army is the main force to maintain order in the liberated areas, and it is impossible for the expeditionary force to carry out security tasks, and there are not so many expeditionary forces that can carry out such non-combat missions. Furthermore. For example, in the rescue of the wounded, the organization of civilian support forces. The Mexican government army has a certain role in gathering intelligence and instigating rebellion. Therefore, in addition to asking the Army Command to provide him with more troops, Gu Xunlei also asked for the size of the Mexican government army to be expanded, and for the Army Command to give him more authorization, so that he could sign a higher-level agreement with the Mexican government army and carry out more in-depth cooperation.

Similarly, in the first battle, Gu Xunlei suffered a lot. And when preparing for the second campaign, he spent a lot of time summing up lessons learned, which were used in the second campaign. For example, when advancing into the heart of Mexico, armored units, especially heavy armored units such as tank divisions, are not very useful. In the mountainous regions of Mexico, it is difficult for tank units to deploy quickly, let alone at high speeds, so it is impossible to exert their rapid assault capabilities. The logistical needs of tank units are quite huge, and they are not very flexible in combat, which also drags down other troops. On the contrary, light armored units, mainly armored combat vehicles, performed much better on the battlefield. Therefore, Gu Xunlei left the two tank divisions at that time behind, and at the same time replaced the four tank divisions newly provided by the army command with armored divisions, and all of them were replaced with light armored combat vehicles. The two remaining tank divisions were mainly used to attack fortified positions, and were not of great use in the advance of the campaign.

In addition to adjusting the establishment of ground combat units, Gu Xunlei also strengthened the input of air forces, and in early May put forward a request to send airborne troops to participate in the war. By the end of May, the Army had dispatched more than 2,000 combat aircraft to Mexico, but because there were no more airfields and serious logistical problems, the Army could not deploy more fighters here. In the past, Gu Xunlei rarely used airborne troops on the battlefield, from Russia to Australia, Gu Xunlei has always been the main force of armored forces, and almost never used airborne troops. The special circumstances on the battlefield in Mexico led him to request for the first time to send airborne troops into battle.

The Army Command quickly met Gu Xunlei's request. At that time, the main battlefield of the army was in Mexico, and there was not much use for it. During the war, the Imperial Army formed a total of eighteen airborne divisions, and the total strength of the airborne troops exceeded 30. These airborne divisions were left in the rear, and there was nothing to do except training. After Gu Xunlei issued a request in early May, the Army Command quickly adjusted the strength of the third expeditionary force sent to Mexico, and after reducing the four tank divisions, the surplus maritime forces could not only replenish Gu Xunlei's four light armored divisions, but also transport additional troops

Airborne division. The two airborne divisions arrived in Mexico at the end of May

With an airborne division, it does not mean that it can be immediately put into battle. At that time, the army airlines lacked airports and effective logistical support, and the main road from the port of San José to Gutierrez could not be fully opened to traffic until the end of the year, and at that time, more than 30 airports in southern Mexico, as well as Guatemala, Honduras and El Salvador, were all crammed with combat aircraft. Even if these airports were to be expanded, it would take enough time and a large number of engineering troops would have to be mobilized, which would certainly affect the construction of the main highways. In addition, the main transport planes used by the Airborne Forces of the Imperial Army at that time had a range of less than 3,000 km, and these transport planes could not be like .=[ After flying, they landed on escort aircraft carriers to replenish fuel and then flew to airfields in Central America. That is, these transport planes could only reach the Mexican battlefield by sea, and the Navy at that time could not provide more transport fleets. As a result, after the two airborne divisions arrived on the battlefield in Mexico, they were left behind by Gu Xunlei, and in the absence of a way to carry out airborne operations, the role of the airborne division on the battlefield was not much different from that of the infantry division.

In the first campaign plan formulated by Gu Xunlei, it was clearly mentioned that two airborne divisions should be used to cut off the logistical supply lines behind the US defense line, isolate the US troops on the front line, and then dispatch light armored units and infantry units to quickly tear apart the US defense line. Complete the campaign offensive. At the end of May, Gu Xunlei also wanted to wait until the airfield expansion was completed and the transport planes for the airborne division arrived before launching a second campaign, that is, a second campaign at the end of June. However, on May 30, Gu Xunlei received an order from the Army Command to launch a second campaign by early June and to advance the front as far as possible to Mexico City.

This was determined by the Prime Minister himself. At that time, it was mainly the Mexican government that wanted to recover the capital as soon as possible, and the progress on the battlefield in Mexico also made the prime minister extremely dissatisfied, and the prime minister felt that he had no face. When the prime minister learned that Gu Xunlei had obtained most of the troops and supplies needed, and that the Mexican government army had expanded to 500,000 after getting more equipment, the prime minister directly ordered the army to attack as soon as possible. Instead of procrastinating for time. Yan Dingyu didn't dare to disobey the will of the prime minister, so he could only personally send an order to Gu Xunlei, asking Gu Xunlei not to delay time any longer.

In desperation, Gu Xunlei had to adjust the campaign plan, and the day after receiving the order, he sent scouts and reconnaissance planes to look for loopholes in the US defense line, and at the same time look for the opportunity to launch the campaign. By 4 June, Gu Xunlei had already adjusted the campaign plan, and the original use of airborne troops was canceled. The frontal offensive forces were strengthened, mainly by throwing in more light armored units. According to Gu Xunlei's new idea. Unable to use the Airborne Forces, he could only annihilate the American troops on the defensive line in stages. After defeating the U.S. defense line at Tehuacán, the light armored forces carried out a deep assault to cut off the line of communication between Tehuacan and Puebla, encircling the U.S. forces in Tehuacán and opening a passage for the attack on Puebla.

This set of Xindi campaign plans basically revolves around light armored forces, and Gu Xunlei estimates. As long as Thuacan is laid, the U.S. military will voluntarily abandon Puebla. After all, Tehuacan is the main defensive line on the periphery of Puebla, and as long as the encirclement is successful, then the U.S. army will not have enough troops to hold Puebla, and Eisenhower will rarely fight uncertainly, so he will not hold on to resistance in Puebla. And if Puebla can't hold it, then it can't hold Mexico City. In other words, Tehuacan will be a key point in the entire campaign, and it is only a matter of time before Thuacan is laid down and the march into Mexico City is made.

After determining this campaign idea, Gu Xunlei quickly lowered the battle plan to combat units at all levels. On 5 June, the reconnaissance operation basically ended, and the scouts and reconnaissance planes basically figured out the deployment of the US defense line in Tehuakan. That night, Gu Xunlei issued a 24-hour combat readiness mobilization order, that is, the campaign would be launched within 24 hours. On the morning of the next day, after determining that the US forces were not making higher-level defensive preparations, Gu Xunlei issued an offensive order at 8:30 a.m., and the first to enter the battle were thousands of artillery and rocket artillery pieces from the 16 artillery regiments deployed on the front line. The time for preparing for fire reached 45 minutes, during which the Army Air Force also dispatched more than 1,000 combat planes to carry out interdiction bombing of the US defense line and prevent the US reserves behind the defense line from entering their positions. At 9:20 a.m., the three light armored divisions in the vanguard launched an attack on the three assault points identified by Gu Xunlei. Ten years later, the news of the second campaign launched by the Army Expeditionary Force was sent to the Navy's Central American Theater Command in Panama City, and Han Shaofeng immediately forwarded this important news to Tan Renhao and Huang Xiaotian, who were looking for an opportunity in Limon City.

Tan Renhao and Huang Xiaotian realized at the same time that this was the opportunity they were waiting for, but the two did not rush to order the fleet to be dispatched, after all, the reaction of the US military was equally important. In the afternoon of the same day, that is, when Gu Xunlei rushed to the front command in Tututepec and directly commanded the front-line troops to fight. Lei Shaoqing sent a new piece of information, a submarine operating in the northeastern Gulf of Mexico, outside New Orleans, found a large convoy of transport ships leaving the port. The flotilla departed early in the morning, and the submarine followed for several hours, unable to sneak attack because of the large number of escort battleships. The captain, having given up the sneak attack, sent back a telegram in the afternoon that the convoy was sailing westward!

After receiving this news, Tan Renhao and Huang Xiaotian both affirmed that the US defense line in Mexico must have been under tremendous pressure, and Eisenhower had made a request for support, otherwise the US military would not have dispatched a transport fleet to transport combat troops and war materials to Mexico. At this point, the time is ripe for the campaign to start, and this is the opportunity that Tan Renhao and Huang Xiaotian are waiting for.
