At 8:30 a.m., the sea northeast of Oahu.

A blue-gray steel tide spewled black smoke and splashed water as it squirmed towards the beautiful sandy beach with green coconut palms as a backdrop.

At the forefront of this current were 144 light infantry landing craft carrying 5,000 officers and men of the 1st Cover Group, deployed in a two-row staggered formation. This dinghy has a full load displacement of 15 tons, is equipped with a 220 hp gasoline main engine, has a maximum speed of 8 knots, and can carry 4 tons of cargo or 36 to 40 marines. It is usually mounted on the side of large landing ships and troop carriers, and after being lowered by a crane, the soldiers climb onto the boat by a rope net laid on the side of the boat.

This was followed by 200 TDC "Alligator" series amphibious landing vehicles belonging to the 11th and 12th Amphibious Infantry Brigades of the Marine Corps and the 1st Battalion of the 1st Task Engineer Regiment, including 140 TDC amphibious personnel carriers (each capable of carrying 30 marines), 20 TDC-GC amphibious engineering vehicles, 20 TDC-G amphibious assault vehicles (equipped with 37mm tank guns) and 20 TDC-H fire support vehicles (equipped with 75mm infantry guns), carrying a total of 5,500 people. The 200 landing vehicles were deployed in three staggered rows for more than 3 kilometers on a frontal basis, unhurriedly slapping the water on the undulating sea.

Behind the landing vehicles, there are two or three rows of high and low hills: including seven "Warwick" class tank landing ships with a full load displacement of more than 4,000 tons, 27 medium-sized general-purpose landing craft lowered from dock landing ships, and 60 mechanized landing craft lowered by large troop carriers, carrying 4,500 officers and men of the 1st and 2nd Tank Brigades of the Landing Corps, the 101st Amphibious Mobile Artillery Brigade, the Mixed Infantry Regiment directly under the 1st Assault Group, and the 2nd Battalion of the 1st Special Mixed Engineer Regiment. The vehicles carried included: 168 Flying Wolf vehicles of the Combat V type 5 (also known as the No. 5 "Flying Wolf"), 28 "Wolverine" mechanized engineering vehicles converted from "Flying Wolf" vehicles, 74 TDC series amphibious self-propelled guns (48 90 grenades and 26 120 mortars), 20 75 mm infantry guns, 180 2.5-ton trucks, 40 1-ton light trucks and 81 motorcycles (27 of which had trailers).

Behind the above-mentioned triple formation, the troop carriers converted from ocean liners are still nervously hoisting the mechanized landing craft on the side of the ship, the figures of the landing crew are squirming like ants on the side rope nets, and the temporary installation of the universal boom is constantly hoisting the trucks that crowd the deck into the boat...... The 120 mechanical landing craft will carry 3,000 officers and men of the 1st Assault Group and 2nd Cover Group, 130 vehicles, and 20 infantry guns to rush to the beachhead before the tide drops.

The most valuable belongings and the most elite officers and men of the Imperial Marine Corps are all placed here!

Among them, on the bridge of the "Huaxing" tank landing ship in the third formation, there stood a Marine colonel in his thirties on his back, tall with thick eyebrows and eyes, and from time to time issued concise and powerful orders.

His name is Pan Guochen, and when he came here ten years ago through another dimension, he was just an inconspicuous special forces corporal, full of unrealistic naval dreams, and wanted to do a big job here, but the reality is cruel, in the first few years, he has been working as a guard for the leader Liu Yun's family.

It is useless to complain, no, complaining is poison, poison that corrodes people's hearts and accelerates degeneration.

Patience, patience, patience, this is a test, a trial, if you can't pass it, it's completely finished-

In this way, he constantly watched and spurred himself, and survived the first few years with his companions.

When Liu Yun announced the end of the test, Pan Guochen excitedly felt that the rocket was about to take off.

Ten years after arriving here, Pan Guochen finally soared to the position of commander of the armored brigade at the age of thirty-three - he should be content.

As a matter of fact, the theoretical foundation for this landing operation with advanced concepts that is currently underway was laid by Pan Guochen.

The so-called "single-handedly laid" is actually to copy and adapt the theories of different time and space in the group's computers, and to preach and use the most likely part of it on the platform of the Naval University and the Marine Corps Teaching Brigade.

The internal treatises "Introduction to Modern Landing Warfare" and "Mechanized Landing Operations" compiled by him have become the theoretical basis for the Marine Corps to organize armored mechanized units and to purchase new types of landing equipment, and the latter has become a high-level textbook for naval and continental warfare. For a time, all the high-ranking officials who came into contact with Pan Guochen's theory were impressed and admired him, and in particular, the central members of the military -- from the Minister of National Defense to the Chief of the General Staff -- all claimed to be his staunch supporters, so some people did good deeds and gave him the laurel of "master of landing warfare." From then on, he asked for people, money, and power, and he did everything without hindrance along the way. The large pile of expensive equipment and the nearly 20,000 well-trained officers and men on it can be said that the existence of this large pile of expensive equipment and its nearly 20,000 well-trained officers and men depends on his hard work.

Now, it's time to prove that you're not vain!

Now, it's time to prove the value of this elite force!

Now, it's time for the opponent to collapse in front of the super-modern concept of warfare!

Shells whistled overhead, and in the distance, from the other side of the beach, a hideous, swollen cloud of smoke like rotting corpses rose - it was getting closer, and the enemy artillery had not yet begun to counterattack?

"The plane, the plane is coming!"

Someone around him shouted happily, Pan Guochen followed the man's instructions and looked up to the port side, and sure enough, he saw a dense group of planes, not to mention fifty or sixty planes, approaching the coast from the west, raising the binoculars to take a closer look, the group slowly flew over the beach, divided into several groups, began to circle, and from time to time birds dropped bombs - air support before landing began.

Pan Guochen looked at the waterproof watch on his wrist - it was punctual, but it was not the most important ......

"Sir, your smoke mask is ready."

Taking the smoke mask handed by his adjutant, what was known as a gas mask in those days, Pan Guochen climbed to the top of the bridge and smiled comfortably when he saw that the wind vane arrow on the mast was still pointing southeast.

Sunset Beach is backed by the Kolau Mountains, which run through the east coast of Oahu, and is surrounded by coconut groves with a road running parallel to the shoreline – Highway 83 that loops around the island's northeast coast.

That morning, Colonel Pokachi's 1st Hawaiian Reserve Regiment was stationed behind the beach with the main force and the attached machine gun and artillery companies.

Colonel Pokaki set up his headquarters in a small valley behind Route 83, and climbed the hill in front of the valley to get an overview of the entire beachhead, on which an artillery observation post was located.

Companies A and B of the 1st Rifle Battalion were deployed in parallel in a line of fortifications, foxholes, trenches, and communication trenches behind the beachhead, each with four machine guns.

Companies C and D were deployed on the rock walls at either end of the beachhead, each armed with four machine guns and two 3-inch field guns. In addition, the Navy had a makeshift battery on the rock wall at the southern end of the beachhead, armed with 1 6-inch naval gun and 2 6-pounder guns.

Companies E and F of the 2nd Rifle Battalion were deployed as reserves on the second-line positions behind Route 83 with two machine guns, and behind the second-line positions were the main artillery positions with four rapid-fire field guns.

Company G and I were stationed in the town of Haleiwa, armed with two machine guns, and although the pier pier pier in Haleiwa had been blown up, the possibility of a direct enemy attack on Haleiwa could not be ruled out, and it was also the supply center of the 1st Reserve Regiment.

The 3rd Battalion had only three companies, of which J Company remained in Wahiawa in the center of the island, and the other two companies were responsible for the east and west coast guards, which had been excluded from the Sunset Beach defenses.

Even so, Colonel Pokaki was confident.

Over the years, he has participated in the landings in Nicaragua and Mexico, and he has learned from them that a few machine guns and field guns in the carefully constructed fortifications behind the beachhead are enough to turn the beach into a slaughterhouse for the landing troops, and with a certain reserve force, it is possible to drive the landing troops several times as large as mine into the sea......

Ten days earlier, when the 1st Reserve Regiment had been ordered to defend the northern shore of Oahu, he had begun to put his theory into practice, cutting down coconut trees, bringing in stones, digging trenches, and setting up fortifications for artillery and machine-gun emplacements. With machine gun and artillery positions as the core, dig foxholes, trenches and communication trenches, and build a circular defense system of support points, and the bushes between each support point are bulldozed and emptied to expand the firing range and facilitate the shooting of enemy soldiers who penetrate into the gaps between the support points.

Even so, the lush, evergreen woods and shrubs on Oahu were the best camouflage for the position, but the colonel forced his troops to cover the exposed bunkers with fresh blades of grass before sunrise every day to prevent aircraft from scouting.

The colonel's slogan was: "The navy is defeated because it looks down on those mechanical flies, and our army is not as stupid as them!" ”

Hearing the explosion of shells on the other side of the beach, Colonel Pokaki hurriedly climbed the mountain bag in front of the headquarters and gathered in front of the artillery observation scope to observe the situation at sea - God! I saw a dark long wall lying across the sea antenna, covered little by little by the tide under the faint black smoke. It is as if thousands of giant whales, pushing tens of millions of tons of seawater, spray a vicious black mist rushing in, and it will not be long before they flood the beaches, flood the interior, shake the Kolau Mountains, and sweep over Oahu......

"It's a good time...... Hit it closer! ”

Colonel Pokachi's operational policy was simple: concentrate fire on the enemy as soon as they rushed to the beachhead and were in a mess.

The only thing that needs to be done now is to wait, to wait for that time to come.

The shelling became more and more intense, huge clouds of smoke dozens of meters high continued to explode in the coconut groves, and soon swarms of annoying mechanical flies flew over the beach, circling in search of targets - unfortunately, unless the pilots of the East Asian coalition forces had clairing eyes, it was impossible to spot the American fortifications covered under the emerald green branches and grass.

Yes, you have huge artillery and planes, but if you can't find an accurate target, you can only shoot blindly like a blind man, and if you want to hit anything, you have to rely on God's blessing, but unfortunately you don't believe in God, obviously, God is on our side.

While Colonel Pokaki was desperately trying to cheer himself up, the coconut grove where Company A and Company B were located was disappearing in large swaths of smoke and flames, and the stumps and fragments of stumps were swaying from time to time in the flying sand and trees......

At about 9:20 a.m., the infantry landing craft of the first column approached the beach strewn with shallow craters – even the most powerful shells could hardly exert their power on the soft, loose sand. The boats adjusted their direction after the last day, ready to take advantage of the tide and waves to seize the beach.

Colonel Pokaki's eyes were fixed on the beachhead, his right hand was holding the telephone receiver, as soon as he shouted "FIRE", signal flares would fly into the sky, rifles and machine guns on the front-line positions would strafe the beachhead from three directions, and the field artillery on the artillery positions would also shoot blazing grenades at the speed of rifles at the enemy who were swarming up like ants.

Come on! Ants, rush up and let's slaughter!

"Sir, another batch of planes!" The adjutant reminded Bokachi.

"Leave them alone."

Judging by the effectiveness of the last batch of enemy aircraft, the colonel did not feel that another batch of aircraft would be able to prevent the impending massacre on the beachhead.

"No one can save you but God...... But God is on our side. ”

At this time, Colonel Pan Guochen on the "Huaxing" could not think about which side of God was or what kind of bullshit the hell God was wearing, so he just tilted his head and kept his eyes close to the binoculars, carefully observing the movements of the second wave of support planes.

As they approached the beachhead, the huge swarm divided into several groups and formed an arc around the beach, on which bombs were dropped almost simultaneously, and instead of circling and strafing a few more rounds like the first wave of support planes, the bombs immediately turned away and soon disappeared.

"It's smoking! It's smoking! ”

The adjutant shouted excitedly, and sure enough, as the plane moved away, puffs of yellowish-white smoke slowly rose from the land around the beach, and swept inland with the wind.

Pan Guochen said that the batch of planes just dropped poison gas bombs with sheep's heads hanging on "special smoke bombs," mainly tear-jerking phenylchloroacetophenone and phenyl arsenic chloride and biphenyl cyanide that sneezed and vomited, and these kinds of poison gas bombs have the advantages of easy storage, quick onset time, and difficult to decompose, and are suitable for loading all kinds of artillery shells, bombs, and even hand grenades. Moreover, it is more "humane" than other lethal poison gases, mainly to promote tears, sneezing, vomiting, and even loss of combat effectiveness, and will not cause obvious physical harm and is not easy to die. The disadvantage is that the weather conditions are demanding, the action time is limited, and the killing effect is poor - the opponent only needs to survive for a while to recover combat effectiveness.

In fact, the pre-landing poison gas attack can only be regarded as "icing on the cake" and is not a necessary condition, and even if the poison gas cannot be dropped due to weather conditions, the troops will still launch a surprise attack according to the original plan, but in that case, it is expected that the losses of the landing force will be more serious.

Modern poison gas was first used in warfare on the evening of April 22, 1915, when the Germans used 500 barrels of 168 tons of chlorine gas while carrying out heavy shelling of British trenches. The result was devastating, inflicting 15,000 casualties and halting all resistance to the British in a position 4 miles long and 8 miles deep. Later, Britain and France retaliated by using phosgene (ClCOCl), which is more toxic than chlorine, and large-scale poison gas warfare became a major part of the First World War.

In this time and space, modern poison gas was first used today - on the morning of January 5, 1915 - by the Imperial Chinese Naval Air Force during the landing operation on Oahu...... God knows!

Pan Guochen was speechless, and subconsciously touched the gas mask on his waist, he didn't want to be smoked by those more "humane" poisonous gases.

A year ago, he witnessed a secret poison gas experiment on death row prisoners and political prisoners, and the terrible expressions of the poisoned people are still deeply imprinted on his cerebral cortex, and he still feels sick to his stomach and wants to vomit when he thinks about it.

This is war, and in order to achieve the end, it is reasonable to do whatever it takes.

We're a little more "civilized" in comparison, aren't we?

Before the smoke cleared, most of the 144 light infantry landing craft of the first group washed up onto Sunset Beach, and about 5,000 Marines from five infantry battalions wearing standard rubber gas masks rushed into the faint yellow smoke like a tide of soft sea sand.

The first few companies to land were left behind to defend the beachhead, while the other units, in battalion units, attacked the predetermined targets in predetermined areas: the rock walls on either side of the beachhead, the road directly ahead, and several small hills behind the road.

"Jumping around burning stumps and falling logs, jumping over scattered deer barricades and barbed wire fences – sometimes throwing a few blasters to open the way, and a trench dangling in front of you, and there was no one in it! Further on, one, two, countless craters, beside which collapsed fortifications and trenches were reflected from time to time - see people, fire! The machine gun crew jumped into the crater, set up machine gun cover, and the company commander asked the grenadier to shoot two white phosphorus rounds to indicate the direction - the poisonous smoke had not yet dissipated, and it was not clear what to see. ”

"The company commander gave the order to attack, and the rifle charged with bayonets! Everyone rushed forward like a race, but the mask was very breathless, and I felt very breathless when I ran here from the beachhead, and the water vapor evaporated from the sweat covered the glasses, and it couldn't be wiped off from the outside, which was really hateful! In this way, I rushed forward without seeing anything clearly, and when I saw something that seemed to be in human form, I didn't care about shooting and assassinating it, and if I accidentally stepped on it, I would step on the air......"

"Rushing to a machine-gun emplacement from the side, the Maxim machine gun with a water sleeve is set up in the bunker intact, where is the machine gunner? Vaguely, I saw a comrade-in-arms pick up a person from the bunker, is it an American soldier? What does not resist for the Devil? Probably smoked by special smoke, the face and neck are full of sticky liquid, are they tears or snot? Probably also vomit and looks disgusting. The comrade-in-arms pulled him out of cover, kicked him to the ground, and gave him a bayonet, and then I saw the epaulettes of the comrade-in-arms - the sergeant's words, it should be the squad leader, and I found out afterwards that it was indeed the squad leader! Since the squad leader has done it, then I can't hesitate any longer, and I will poke it too......"

"The enemy is on the run! Can't stop, keep the pursuit! There was a highway ahead, and the American soldiers staggered onto the road, and the machine guns rang out, knocking the enemy soldiers down on the road like rabbits. The formation was already in disarray, a flare was raised on the left, and the company commander gave the order to regroup, but the third platoon had already rushed across the road ......"
