The Boston Empire's army units did not attack from Port Laayoune, which was closest to the New World, after all, they were fighting across the ocean, and in fact attacking anywhere on the west coast of the Southern Subcontinent was quite far away, and it was almost the same to attack anywhere in the colonies without naval cover. In this case, it is naturally not cost-effective to attack the Laayoune area, which has been heavily defended.

The southern subcontinent was vast and had a long coastline, which was not at all fully defended by the colonial forces of the Allied countries, which totaled less than half a million people, so the fleet of the Boston Empire turned south and carried out a landing operation from the waist of the entire southern subcontinent, in Port Libreville, located in the Gulf of Guinea.

Located near the equator, the port of Libreville is one of the hottest areas in the southern subcontinent, with temperatures above 30 degrees all year round, and the location in the tropical rainforest area makes it difficult to develop, so its suzerain, the Grand Duchy of Sardinia, has not invested much development power here, so although it is a deep-water port, there is no large enough port for shipping.

Due to the lack of attention of the Grand Duchy of Sardinia, the port of Libreville has a garrison of less than 500 men, and even the coastal forts are antique-level artillery, which is not at all useful for the increasingly powerful maritime forces, at most it can defend against pirate invasions.

"There is an enemy attack." A terrible shout echoed over the port of Libreville, and when the alarm bell rang out to the whole harbor, at dawn the Boston fleet, which had always been in large formation, appeared on the surface of the sea, and in the face of the huge fleet, the sentinels who watched from the batteries trembled all over, and their faces were already dead in horror.

Hearing the sentinel's warning, Governor Lipnan of Port Libreville was the first to rush out of the governor's palace, and he immediately summoned his soldiers to the fort to defend it. Lipnam, who had not been much vigilant, never imagined that the first idea of the Boston Empire would actually hit him.

Eight 45,000-ton Missouri battleships were the first to turn, aiming their massive 381-millimeter guns at the high batteries on the headland. As a burst of gunpowder smoke rose, the dense cannonballs accurately hit the headland, and before the Sardinian artillery could react, the huge shells had already fallen on the headland one after another, and the battery was quickly submerged in a cloud of dust and smoke.

The battleships carried out the shelling rhythmically, and the bluestone batteries were so broken that before they could fire, the Sardinian artillery had already lost most of its artillery, and the men were also killed. The Bostonians attacked with considerable ease, with only a dozen rounds of shelling, and the Sardinians had lost their ability to resist, and the Governor of Lipnan could only surrender with the remaining remnants of the army under a white flag.

Boston easily captured the port of Libreville, and a large number of merchant ships were able to dock and transport goods to shore. It was to be used as a base for the Boston Empire's assault, so in addition to the army and a number of engineers, they would expand this small port, which was not taken seriously. Thanks to its strategic location, the Port of Libreville will soon become one of the largest ports in the Southern Subcontinent.

In the last moments before the surrender, the Governor of Lipnam sent a telegram to the other colonies about the occupation of Port Libreville, and then destroyed all classified documents, and the Boston Empire had no intention of hiding its intentions, and with a good harbor as a foothold, they were going to make a big deal in the southern subcontinent.

With a large number of bulldozers running rampant through the rainforest, the Boston Empire's engineering units were well prepared this time to open the way for the arriving army units to attack. The first force of 30,000 men marched eastward, and they were to march along the Ogowe River in the direction of the upper reaches of the Lu, capturing the fortress of Zanagar, the farthest from the coast of the Sardinia colonial army, and completely cutting off the north-south connection of the Allied colonies in the southern subcontinent.

The severance was only the first step, and the landing of the army forces would draw four corps of troops along the coastline south, sweeping through the Confederate colonies in the south, while the other hundreds of thousands of troops would attack all the way north to the Mediterranean coast.

To the south of Port Libreville was the former Boston Empire colony, which was given to the Yaman Empire when the colony was exchanged for oil, and it was Walbeck, the Angolan governor of the Yaman Empire, who was stationed here. In his early years, Walbeck served as a military attache in the Chinese Empire, and in his spare time he had contact with many officers of the Chinese Empire, and was invited to audit several army academies in the Chinese Empire, so he had a lot of knowledge of advanced tactical concepts.

Brilliant and studious, Walbeck had a keen sense of politics, and his time as governor of Angola coincided with the civil war in the Habfsburg Kingdom and the powerful intervention of the Boston Empire in the Western Continent. He had a premonition that there would be a war between the Boston Empire and the Allied bloc, and the Boston Empire had a navy far more powerful than the Allied Powers, so if the two sides went to war, the Angolan colony would definitely become an isolated island, completely unable to receive domestic support. Therefore, he began to be self-reliant from that time, relying on all the resources of the colony to train a combat-ready neo-colonial army unit for himself.

Under Wallbeck's training, Angola relied on their advantage of relying on the colonies of the Chinese Empire on both sides, and with the help of the coastal railway lines of the Chinese Empire, they made a lot of profits for the Yaman Empire. This money was not only handed over to the state in large quantities, but also kept a lot of surplus funds for the colonies, and Walbeck relied on these funds to train a large number of soldiers, and soon established a colonial army of 30,000 men, of course, due to the small number of whites, only part of the colonial army's officers and military medical corps were composed of whites, and a large number of soldiers and most of the officers were native.

In order to increase the enthusiasm of the natives, Walbeck did not discriminate against the aborigines, he boldly appointed the natives as senior officers, and was even able to command the whites to fight, so the morale of this unit was quite high, and the internal unity was very strong.

In terms of the policy towards the local aborigines, Walbeck used the Huairou policy, and at the same time relied on the economic pull effect, which greatly improved the living conditions of the local aborigines, which made the aborigines very supportive of him. Taking advantage of this favorable situation, Walbeck formed a reserve system composed entirely of indigenous people, developing more than 300,000 indigenous militias.

Relying on such a policy, Walbeck had enough troops, but if the weapons were insufficient, no matter how many troops were useless, he knew very well that once the war started, the country would be completely unable to supply it, so he tried his best to replace all the weapons of the colonial army with the standard of the Chinese Empire, and he planned to rely on trade with the Chinese Empire in wartime to support the war of the entire colony.

While the colonial governors everywhere were only interested in pleasure and looting the natives, Walbeck was immersed in training the army and preparing for war in a down-to-earth manner, and the other governors laughed at his stupidity.

But this time, Walbeck's vision was finally confirmed, and his preparation worked. After learning that the Gabon colony of the Sardinian Empire had been invaded and that the Angolan region had been truncated as an island, Walbeck went into action.

The colonists had no navy, no heavy weapons, and would not succeed if they wanted to defend the coastal line, so Walbeck requisitioned all the reservists, formed a large number of small forces, shrank to the south and east, relinquished the coastal areas, and gathered troops in the rainforest near the border of the Chinese Empire, relying on this to fight a guerrilla war with the Bostonians. When the governors were in a hurry, Walbeck became the only governor who was ready for war, and this war in the southern subcontinent became Walbeck's war alone.

Wolbeck soon made contact with the Southern Counties of the Chinese Empire, and at the behest of the Imperial Cabinet, the Empire privately reached an agreement with Walbeck in both the Southern and Mozambique counties of the Southern Subcontinent that the Chinese Empire would provide supplies and weapons for his troops, as well as provide necessary medical care for their wounded, and even establish several camps in the border areas for them to rest and train new soldiers.

With the secret assurances of the Chinese Empire, Walbeck immediately divided his troops into small units and infiltrated the Gabon region. It's not his style to defend and he wants to attack the opponent before they attack. Walbeck personally led a force of more than 8,000 men all the way north to the Ogoway River.

"This damn rainforest, it's hot to death, why don't you make a little rain and refresh yourself." Sean, who was visiting the Southern Subcontinent for the first time, sat on a truck delivering supplies, with the placket of his clothes wide open, cursing the weather loudly, apparently very uncomfortable with the climate of the rainforest.

"Forget it, you still don't pray for rain. In the rainforest, the next rain will be more humid and muggy, the clothes will be completely attached to the body, and the sticky sweat will not get out, which will make the taste even more uncomfortable. Charlie, a veteran who has been here for almost two months, comforts his comrades.

"It's better to go to the battlefield and have a good fight with the Allies, even if you are killed, it is better to live and suffer here." Sean said angrily, as if he didn't want to stay here for a moment.

At this moment, a gunshot rang out, and the driver of the first truck in front of the supply convoy was shot in the head, and the sniper rifle bullet with huge kinetic energy slammed his body into the car door at the moment of concentrating the driver, and then rebounded back, his head had been completely shattered, and the splattered flesh and blood stained the entire car red. The steering wheel was tilted under the influence of the corpse, and the car crashed straight into the big tree on the side of the road and did not move, and the car that crossed completely blocked the road that was not wide enough.

"If there is an enemy attack, quickly hide and return fire." The officer in the convoy commanded loudly.
