In fact, although the explosive power of the ***** is large, it is also limited when used for medium and large-caliber artillery, and the destructive power of the stone fortress is not substantially improved. However, after the People's Army fleet used high-burning bombs, the fire of the fort increased significantly, at first the fort was only a little fire, but quickly the fire increased greatly, and it was connected, and the flames reached more than 20 meters high, like a mountain of flames, reflecting half of the sky.

The French soldiers on the other three batteries could see very clearly, but they couldn't figure out what the People's Army fleet was using, and it would ignite such a big fire, because the batteries were all made of stone, and there was not much combustible in itself.

But the fire still has a great threat to the fort, first of all, the fire will inevitably lead to high temperature, there are a large number of shells stored in the fort, and the high temperature is easy to cause the explosion of the shells; secondly, the fire will consume oxygen, resulting in a local lack of oxygen zone, so that the personnel suffocate to death, because it is the ventilation situation in the fortress is not good, and it is easy to cause the result of personnel suffocation.

And just after the People's Army fleet switched to high-inclammation shells, after about 15 minutes of artillery bombardment, and successfully destroyed the three forts of the fort, the resistance on the fort basically stopped, mainly due to the use of high-inclamority shells, forming a local hypoxic area, although not all shells fell on the fort, but also basically distributed around the fort, the effect was not much worse, and finally caused most of the French artillery in the fort to suffocate due to lack of oxygen, only a small part escaped from the fort at the extreme, and saved their lives.

Finally succeeded in destroying the first battery, it took about 40 minutes, but the number of high-inclammation bombs used was about 4 percent, because this high-inclammation bomb was extremely unstable, so the fleet did not dare to bring more, this time it was the most, but it was only 1/ of the total number of ammunition. 3, but Wang Hailong was also very satisfied with this result, after all, it saved the fleet a lot of trouble, so he first ordered to send a part of the landing force ashore to control the battery, in case the French soldiers who escaped from the battery returned, and immediately ordered the fleet to advance and attack the second battery on the east bank.

The fleet's attack on the 2nd battery on the east bank was basically the same as that of the 1st battery, first destroying the open artillery on the battery with intensive fire, then using high-inclamibility shells to kill or injure the artillery in the fort, or driving the artillery away from the fort, and finally sending a landing force to occupy the fort around the fort.

In less than one and a half hours, the People's Army fleet successfully destroyed the two batteries on the east bank of the Saigon River estuary, and the three battleships and three armored cruisers immediately turned around and attacked the two batteries on the west bank。 By this time, however, the KPA landing force had already set up positions around the two batteries, and a fierce battle broke out between the two sides.

However, the landing force of the KPA was drawn from the personnel of the warship, not a special land combat unit, so the number was not large, and each battery could only be guarded by about 60 people, after all, the manpower on the warship was limited, and the guard soldiers of each battery had one company, plus the artillery who fled, the total number was more than double that of the KPA.

And Wang Hailong also immediately ordered, ordered the drone to quickly take off, reconnoiter the enemy's position, and ordered the cruiser squadron of the five protective cruisers to immediately close to the shore to support the landing force to fight, because there is no threat of batteries at this time, so the cruiser can also approach the shore, under the guidance provided by the drone, with the small and medium-sized guns on the ship to shoot at the shore, to strike at the enemy who try to recapture the battery.

Although the 5 protective cruisers only used guns under 100 mm, they were enough for the army, and a few guns went down to wipe out the French counterattack force, and they dared to hold out any longer and hurriedly retreated.

At the same time, the KPA fleet launched an attack on the first battery on the west bank, and when the KPA fleet attacked the east bank battery just now, although the battery on the west bank wanted to help in the battle, it was powerless, but it was completely ready to meet the battle, so as soon as the KPA fleet attacked, the battery launched a counterattack, and for a time the shells rained down on the sea, stirring up countless water columns, but unfortunately it was at night, and this magnificent scene could not be seen clearly.

The KPA fleet still concocted the same method, but after the attack of the first two batteries, there were less than 20% of the high-burning bombs left, although all of them were fired, but it was not enough to form a lack of oxygen, so that the artillery in the fortress suffocated to death, at most they could only feel difficult to breathe.

However, at this point, there was no other way but to rely on artillery to destroy the defense of the battery, so Wang Hailong ordered that the fleet go forward another 2,000 meters to shorten the attack distance to about 8,000 meters, so that not only the hit rate is higher, but also the kinetic energy of the artillery is more powerful, because for the 200 mm artillery, the kinetic energy at 8,000 meters is much greater than the kinetic energy at 10,000 meters. But in this way, it also increases the risk of being shot, after all, 8,000 meters is not an absolutely safe distance.

The attack on the first fort on the west bank lasted more than one hour, and although the fort was extremely strong, it could not withstand repeated attacks, and finally the fort was broken one by one by the KPA fleet, and the entire fort was destroyed. Moreover, unlike the two batteries on the east bank, the batteries were completely destroyed and could not be used again, so they could be dispensed with for the landing force. The battleship Weiyang and the armored cruiser Takumi were both hit, but fortunately, the damage was not large and did not affect the combat effectiveness of the warship.

But it took 1 hour and 20 minutes to destroy this battery, which is about the same time as destroying the two batteries on the east bank. Although the total time to destroy the three batteries was less than three hours, which was still within the estimated time, all the high-burning ammunition had been used up by this time, and according to the situation of destroying the first battery on the West Bank, it was certainly impossible to destroy the last battery in an hour.

Wang Hailong thought about it for a moment and decided to order the battleships and armored cruisers to continue to attack the last battery on the west bank, while the protective cruisers Haike, Heidi, and Hainault, and the five warships with the destroyer detachment, immediately set off and sailed into the mouth of the Saigon River to attack Saigon Port.

There is still a distance of about 45 kilometers from the mouth of the sea to the port of Saigon, and although this section of the river is wide and deep, the river is not as good as the sea, and it is impossible for the warships to sail at a high speed, so it will take at least two hours, or even three hours, for the fleet to complete this section of the river, and it will definitely not wait for the final battery to be completely destroyed.

However, by this time, the two batteries on the east bank had been completely destroyed, so as long as the fleet walked close to the east bank, plus there was the cover of the night, and at the same time the battleships and armored cruisers continued to attack, and the attention of the batteries was diverted, there was still a great chance that it would successfully pass through the mouth of the Saigon River and sail into the river.

And battleships, First, the armored cruisers were larger in size and had a deeper draft; second, they had to attack the forts, and it was impossible to enter the river, and two warships had to be left on the east bank to prevent the French from seizing the forts again, so the People's Army fleet could only send these eight warships into the river to attack Saigon Harbor, of course, after breaking through the estuary, Saigon Harbor's defensive strength was average, after all, it had already reached the inland river, and it was impossible to arrange any more powerful defenses, although batteries were also set up on both sides of the strait, but they were all small and medium-caliber guns of less than 100 mm, and the firepower was inferior to the five warships of the destroyer squadron。

Although there are also 8 French warships moored in the harbor, they are all small and medium-sized warships of less than 3,000 tons, while the Haike and Heidi are medium and large protective cruisers of more than 5,000 tons, and the tonnage of the Hainault is also 3,500 tons, which is enough to deal with these 8 French warships.

So three battleships and three armored cruisers immediately launched an attack on the last battery on the west bank, and the eight warships that received the order, headed by the destroyer River Dragon, sailed along the east bank to the mouth of the Saigon River at a speed of 7-8 knots, and the River Dragon was the warship with the smallest tonnage and the shallowest draft among the eight warships.

Sure enough, after the KPA fleet's attack was launched, the last battery on the west bank also concentrated all its firepower to launch a counterattack against the KPA fleet, and in the darkness of the night, it was not found that a fleet had sneaked into the river and sailed towards the port with its eyelids lowered.

After about 20 minutes, the fleet that had infiltrated the inlet of the river had all passed through the mouth of the Saigon River and therefore turned to the middle of the channel, which increased its speed to 12 knots and headed for Saigon Port.

At this time, the battle between the KPA fleet and the battery had entered a white-hot situation, and the open-air artillery had been destroyed by the fire of the KPA fleet, and destroyed 2 152 mm gun forts, but at this time the battery still had 2 forts, and it was 4 large-caliber artillery forts that could still fight, and the guns hidden in the forts fired hard at the KPA fleet, and the Boyang also suffered a 152 mm shell.

In the face of the enemy's strong fortress, the KPA fleet also changed its tactics, with 3 armored cruisers adopting the tactics of loitering to attract the fire of the battery, while the 3 battleships concentrated the main gun fire, according to the guidance of the drone, first carried out a concentrated attack on a fortress with 280 mm guns, and the 3 battleships carried out 3 consecutive salvos, hitting a total of 11 305 mm shells on the fortress, from which 3 shells hit the top of the fortress, and the top was the weakest part of the fortress's defense, which was immediately blown through and completely destroyed.

Subsequently, the KPA fleet did the same and destroyed three other large-caliber artillery forts in succession, although there were still two 152-mm gun forts left in the battery, but the KPA fleet was no longer a big threat. However, one hour had passed, and Wang Hailong was also relieved, and now he was waiting for the news of the attack on the port, and ordered the Haimi and Haisha to also sail into the river to support the fleet attacking the port.
