Since the first battle between China and the Philippines, especially since the two countries declared war one after another, the navies of the two sides have engaged in large-scale confrontations on the Philippine side of the Dongsha and Zhongsha Islands. At the same time as the first battle took place, the main force of the Philippine fleet was only 5 hours away from the area of engagement, and the "main force" of the South China Sea Fleet was only less than 5 hours away, but after the battle, the two fleets invariably stopped advancing, and all kinds of electronic instruments and satellite navigation facilities were in full operation, and in the middle of the night, the Chinese fleet carried out a round of missile attacks on the Philippine fleet, and then the two sides disengaged. The Chinese Navy's heavy pressure on the territory has made the Philippine side extremely nervous, and the two aircraft carrier battle groups far away in Guam have not yet been assembled (one of which was originally stationed in Japan and the other is originally stationed in Hawaii), so they urgently marched to Southeast Asia at high speed to deter the main force of the Chinese fleet, which is very arrogant in the South China Sea! According to intelligence, the Chinese fleet that appeared in the ocean west of the Philippines was composed of an aircraft carrier battle group and a strike formation of the "Far East mode" composed of nine large warships of various types, of which the aircraft carrier battle group included seven large destroyers, six large frigates, and several submarines.

After decades of rapid development, the Chinese Navy has greatly expanded, and has not only become an important sea force in the Far East, but also very powerful in the world, and has been able to carry out medium- and long-distance ocean-going operations! The main force of the navy is divided into five major fleets, and not only the original Four Seas Fleet has been strengthened, but also a more powerful fleet has been formed, and now it has been reorganized into four fleets. Broadly speaking, the main force of the Chinese Navy consists of three carrier battle groups and six mixed fleets, supplemented by a large submarine force. The Bohai Fleet is mainly composed of a mixed fleet and a large number of ships, supplemented by a large number of warships of various types, mainly defending the Bohai Bay and can go forward to support the Yellow Sea. The East China Sea Fleet has assembled the main forces of the original Yellow Sea Fleet and the East China Sea Fleet, and now has the "Huangpu" aircraft carrier battle group and two mixed fleets as the main forces, mainly responsible for the north of central Taiwan, and responsible for guarding East China and blockading Taiwan Province. The South China Sea Fleet, on the other hand, uses two mixed fleets as its main striking and escort forces, and with the cooperation of a large number of warships and other warships, it not only guards the southern gateways of the south, but is also responsible for the task of blockading the southern half of the island of Taiwan, as well as some combat missions in Southeast Asia. The South China Sea Fleet is the most powerful of the four major fleets, which is dominated by the "Zheng He" aircraft carrier battle group and the "Dongfang" aircraft carrier battle group, plus a mixed fleet, whose escort and strike capabilities occupy the first place among the fleets.

Since its completion, China's aircraft carriers have become the focus of attention of all countries in the world, believing that they are an important symbol of this great land power in the East going deep into the sea, and have already posed a threat to the US Far East strategy, and have become a powerful armed force that resists the US Navy in the east, the Japanese fleet in the north, the Indian Navy in the west, and Southeast Asian countries in the south. And the South China Sea Fleet has always been the focus of close attention of Southeast Asian countries, and they are all closely monitored! When the "Zheng He" aircraft carrier battle group and other ships went out to the ocean west of the Philippines, the shock caused by it can be imagined, and this is almost all the power in the South China Sea, does China want to take advantage of the hesitation of other countries to take the Philippines first, or paralyze the Philippines' war capability, and create a fait accompli before the United States intervenes? At this time, not only the Philippine government was very nervous, but also the governments of Southeast Asia, and even the US government was very uneasy, and while protesting to the government of country Z, it ordered the advance detachment to speed up and must "reach the Philippine Sea before the collapse of the Philippines." Countries around the world are closely monitoring this imminent "expanded war"!

The war in Southeast Asia was rapidly expanding, and it had already expanded when the American advance detachment had just left Guam and was far from reaching its designated position. On the afternoon of the 21st, the Southeast Asian War officially broke out, and at more than 6 o'clock in the morning of the 22nd, the Sino-Vietnamese War quickly began, and the Chinese Navy carried out a large-scale attack on Li Chi Minh City in the southern region of Vietnam, while in the north, the Chinese Army launched a "bamboo offensive" and carried out a fierce attack on the North Vietnamese Military Region; At the same time, a large number of fighter planes and missile units assembled in the south carried out saturation attacks on Vietnam's front line, in depth, and on various military points; a large number of bomber groups took off from front-line airfields and inland airfields to bomb Vietnam's strategic and military priorities; and a large number of fighter planes took off from front-line airfields to carry out combat escort and shoot down Vietnam's attacking planes...... Beginning at about 6 o'clock in the morning, a large number of medium- and long-range missiles filled Vietnam's military airfields, and hundreds of missiles were tilted onto Vietnamese soil from land, sea, and air.

The first round of attacks began at 6:25 a.m., with a large number of missiles fired from long-range missile bases in the Chinese mainland passing through the clouds, entering the stratosphere, and then through the clouds and pounced on Vietnamese missile bases and military airfields; The second group of attacks, carried out a little later, was launched from the sea, dozens of * bombers pounced on the land of Vietnam from ships, and almost simultaneously, bombers taking off from aircraft carriers carried out missile attacks on parts of the area; The third group of attacks consisted of missile attacks by large numbers of bombers on the Chinese side of Vietnam or at sea far from the coastline. In less than 20 minutes, three successive batches of attacks unleashed a large number of missiles on Vietnam, with the result that a large number of Vietnamese missiles exploded on the spot before they were launched, a large number of advanced fighters were destroyed on the tarmac before they could take off, and most of the military airfields could no longer be repaired and put into use in a short period of time. Earlier, Vietnam's national electricity system was paralyzed, and the whole country was plunged into permanent darkness before dawn, with news dissemination and media transmission interrupted in most areas......

At about 7 o'clock in the morning, the Northern Military Region of Vietnam was first attacked by Chinese long-range missiles, and then bombed indiscriminately by Chinese bombers. By 10 o'clock in the morning, the Vietnamese army's northern border defense line had tended to collapse, and many areas had been broken through more than 40 kilometers, and the collapse seemed inevitable...... The entire Northern Military District is about to collapse! By about 12 o'clock in the morning, in addition to some areas still resisting, Vietnam's northern military district has completely collapsed, more than 100,000 troops, more than 20,000 people have been killed, a small number of them were killed in the other side's charge, most of them died in aerial bombardment or missile attacks, a large number of troops did not have time to withdraw in time, nearly 100,000 people were besieged, most of these soldiers were captured, the entire northern military district troops were almost lost, and the forward of the squadron pointed directly at the heart of Vietnam!

And at the same time that the Northern Vietnam Military District was devastated, the South Vietnam Military District also suffered a heavy blow. The squadron launched a landing operation to capture the city of Li Zhiming, with two Marine brigades as the spearhead, with the support of naval ships, airborne troops and a large number of army amphibious combat units to seize this central city in the south! At 7:30 a.m., the advance detachment of the Marine Corps took advantage of the fierce air battle and, with the cooperation of the airborne troops, landed in Phan Thiet and Nha Trang, north of Li Chi Minh City. The 3rd Brigade soon occupied Phan Thiet, and after receiving the support of some army units, the main force quickly attacked southward, and then divided into two routes, part of the troops attacked westward to disturb Bienhoa to block reinforcements from the direction of Li Zhiming City, and the main force attacked and advanced in the direction of the port city of Vung Tau, with the cooperation of the airborne troops and the marines who forcibly landed from the vicinity, especially with the cooperation of the naval ships cruising nearby, and attacked by water in multiple ways, and at about 13:30 p.m., they seized the main pier of the port to meet the army troops moored in the open sea, With a large number of troops ashore and a large amount of heavy equipment, by 16 o'clock in the afternoon, one division of army units had already set foot on Vietnamese territory, and then divided into several columns to attack the city of Li Chi Minh. The combat mission of the 2nd Brigade was even more important, almost at the same time to capture this elite unit in Nha Trang, the first target to seize was the famous Cam Ranh Bay, and to ensure that the port facilities were not seriously damaged by the Vietnamese side. Therefore, in addition to leaving part of the troops to protect the stronghold of Nha Trang, the main force of the brigade advanced along the railway attack, and because the airborne troops seized many important strongholds, they quickly approached Cam Ranh Bay.

For the Chinese side, whether or not they can successfully capture Cam Ranh Bay is related to the smooth implementation of the follow-up battle plan, and even the success or failure of the entire Vietnam War plan. As for the Vietnamese army, as long as this important port town does not fall into the hands of the Chinese side for one day, the other side will delay the capture of Li Chi Minh City for one day, and it may even be possible to smash the strategic attempt of the squadron. However, the situation is clearly in favor of the Chinese side, and the Chinese side, which is determined to win, cooperates with each other in many ways and attacks rapidly, with the main force of the 2nd Marine Brigade attacking in the north, the 3rd Brigade responding to the surprise attack of the troops in the south, and the sky being bombarded indiscriminately by the Chinese Air Force, and the uninterrupted strikes of Chinese warships on the sea, as well as the strong attacks of the task force, and the sabotage and obstruction of the Chinese Airborne Forces inside...... By about 15 o'clock in the afternoon, the main ports had been completely controlled by the squadron, and the landing ships and merchant ships cruising in the nearby waters had begun to send army units and various supplies and equipment ashore; By 8 p.m., the number of troops had reached more than 20,000, and the troops that had landed in advance had already advanced in the direction of Bang Ma Thuot. At this time, it was only a matter of time before the squadron captured southern Vietnam, and sure enough, at about 12 o'clock in the evening, the "sea route coalition army" attacking Buon Ma Thuot had completed the encirclement with the cooperation of the air force airborne troops.

Buon Ma Thuot is a transportation hub city in southern Vietnam, where a number of strategic highways intersect, and the successful encirclement of the squadron, especially the cutting off of the nearby strategic highways, is equivalent to completely closing the door of the southern Vietnamese army to the north, and cutting off the main channel for the northern Vietnamese army to aid the south, and the Vietnamese army south of Buon Ma Thuot has become isolated.

Contrary to the Vietnamese military's estimates, the squadron did not pay enough attention to the city of Le Chi Minh, but showed extraordinary enthusiasm for some nearby airfields. The areas around Li Chi Minh City, especially the several airfields in the north that have been heavily bombed (most of the air bases in southern Vietnam are located in the north of Li Chi Minh City), have all fallen under the control of the Chinese side, and when the Vietnamese who woke up like a dream wanted to retake it, they would gain nothing even if they paid a heavy price; many airports were basically "intact" except for the damage caused by the Chinese's own bombing, and there were still thick smoke from the burning of fighter planes in some places waiting for the engineers to clean up.

In the southern battle, the battle to capture Cam Ranh Bay was the fiercest, far exceeding the losses in the Battle of Vung Tau. Although the navy and air force did not suffer any losses, the ground forces suffered heavy casualties, and some units even almost lost their combat effectiveness, such as the airborne detachment and task force that attacked and seized a certain port, and when the large force broke the siege, only more than 20 people were still fighting, with a loss of nearly 60% of the troops, and the proportion of seriously wounded reached about 40%; A certain battalion of the third brigade, which was a surprise attack, was reduced from more than 600 people before the war to more than 200 people, and the casualty rate reached almost two-thirds, of which nearly one-third were killed in direct battle.

By 6 o'clock in the morning of the 23rd, the total number of squadrons that landed had reached more than 60,000 people, more than the total combat strength of all the military districts in southern Vietnam, and the army units that took over the main task of the operation not only contained the enemy attacks coming from the north to help, but also blocked all the communication arteries leading to the city of Li Chi Minh, besieged the remnants of the main force of the Vietnamese army in the south under the city of Li Chi Minh, and eliminated the threat of the Vietnamese army to certain Chinese troops. After a whole day of fighting, the squadron has completely suppressed the main force of the Vietnamese army, the marines, the airborne corps and the army units have formed a strength advantage over the Vietnamese garrison, and at about 10 o'clock in the morning of the 23rd, the Chinese air force began to use Vietnam's land airfields, a large number of aviation facilities were transported to Vietnam, and the damaged airfields were quickly rebuilt......

At the same time that the Vietnamese Army was attacked by China's combined land, sea and air forces, Vietnam's air force was also forced to engage in fierce confrontation with the Chinese Air Force, and a large number of Vietnamese fighters taking off from several military airfields that had not yet been destroyed met China's long-range bomber groups under the guidance of ground radars, and had to engage in fierce exchanges of fire with Chinese escort fighters and hunting fighters; Vietnam's relatively weak navy, although cowering in the harbor, was also attacked by missiles and attack planes from a distance, and was almost completely lost in the day's battle. Vietnam's air force was also very tenacious, and although most of its radar positions in the country were destroyed, it still relied on its airborne radar and the remaining radars on land to meet Chinese fighters, and fierce battles ensued. However, the battle between the air forces of the two sides is completely one-sided, and Vietnam lacks early warning aircraft, let alone satellite navigation facilities, and mainly relies on ground radar guidance and airborne radar search. The first round of the Chinese attack wave was the Vietnamese command system and interfered with all of Vietnam's connections with space, early warning aircraft were blown up, satellite navigation was cut off, international connections were temporarily blocked, and even its domestic communication links were disrupted. China's fighter jets are not only the most advanced fighter in the world, at least half a grade higher than Vietnam's aircraft, but also China not only has theater early warning aircraft, but also has air navigation system support, and its advanced electronic search capability is not comparable to that of the Vietnamese army. When China concluded that Vietnam's early warning aircraft could not be activated, it decided the outcome of the double battle, although central Vietnam is a relatively light area of China's blows, and some Vietnamese air forces still have the will to fight, but the area is narrow, there are not many air bases, the strength is relatively weak, the number of fighters that can be lifted into the air is very limited, one-on-one confrontation, Vietnamese fighters may still have a chance, but after combining various advantages, 2 to 1 or even 3 to 1 advantages, since the first Vietnamese fighter was shot down in the air battle, They were shot down one after another, and later they could not withstand the losses and had to withdraw from the battle and completely surrender their air supremacy. Compared with the bitter resistance of the air force, the Vietnamese navy did not put up a decent resistance at the beginning, and handed over the right to dominate the sea and the right to station in some ports early. The first ship was sunk by the Chinese Navy at about 8 o'clock in the morning of the 22nd, and by about 12 o'clock in the morning, six ships had been sunk by the Chinese Navy and four warships were seriously damaged...... As a result, 12 large ships of the entire navy were sunk, and four large ships were seriously damaged, the vast majority of naval ships lost their combat capability, and the entire navy was forced to retreat to its home port, and only two warships "broke through the blockade" and fled to the ports of the allies! The battle against the Vietnamese navy was most intense in the two southern ports, which were attacked not only by Chinese long-range missiles, but also by the Chinese navy and air force.

The first to be attacked was Vung Tau's naval forces, except for two large warships that desperately passed through the minefield and escaped to the Gulf of Thailand, the remaining two large warships and more than a dozen small warships and merchant ships were all sunk by Chinese shore-based aircraft and carrier-based aircraft; Almost at the same time as Vung Tau was attacked, the naval ships stationed in Cam Ranh Bay were also dealt a devastating blow, and the swarming Chinese naval aviation and carrier-based aircraft carried out indiscriminate attacks on all the warships in the military port, and almost none of the ships escaped the attack, and after the attack planes in the sky circled and left, not a single warship in Cam Ranh Bay could no longer float on the water, and in order to avoid the bombing of Chinese planes, some warships even rushed into minefields, and there were columns of water rising into the sky everywhere, mines, missiles, And the explosions of warships come and go, like hell on earth! Of course, the Chinese have not paid a price, it is said that in Vung Tau there has not been a single warship or transport ship hit mines, but in Cam Ranh Bay, even if the demining efforts are intensified, there are still incidents of transport ships hitting mines.
