Of course, the reason why the Japanese Navy used submarines in this way was because none of the heads of the Japanese Combined Fleet and the Navy's Command Department knew about submarines, and because of their stubborn and rigid thinking, they stubbornly clung to the "doctrine of big ships and huge artillery," which had been proven obsolete by war, and stubbornly regarded submarines as an auxiliary force to destroy large US surface ships, so they vigorously let submarines attack and even attack US warships when the enemy was on high alert.

But in fact, the Japanese have their own reasons for doing this.

Their reasoning is...... The industrial capacity of the United States is too strong, and the destruction of some merchant ships will not cause much damage to the American army, and the Americans will soon be able to build new merchant ships and replenish them, so it will have little impact on the outcome of the operation; However, if it is to sink warships, because of the long period of building warships, the United States may not be able to replenish them for a while, so that it is possible to change the balance of forces between us and the enemy and ultimately help the Japanese Navy to seize sea and air supremacy, and even win the entire war.

This reason seems to be valid, but the problem is that the reason why the submarine is sunk in the water is to hide and to attack the enemy unprepared, and the Japanese play submarines like this...... That's almost a fragile submarine and a thick-skinned warship, and in doing so, you may win a few battles in a local battle, but the whole war will be ...... The performance of Japanese submarines and torpedoes was good, and the quality of sailors was also very good, but they achieved unsatisfactory results with huge casualties under the wrong strategy and tactics.

Hyakutake Haruyoshi is a typical Japanese soldier, so he can't escape the inherent thinking of these Japanese, so his idea is strategically correct, but it is ridiculously wrong in terms of specific execution tactics......

That night, Hyakutake Haruyoshi sent the 3rd Submarines and the 7th Submarines to the waters south of Kuah Island...... The establishment of the Japanese diving team is generally divided into three diving teams, each diving team has three submarines, plus two command ships directly under the team, each team has 11 submarines.

Other words. Hyakutake Haruyoshi sent 22 submarines in the first batch.

After a few hours, Hyakutake Haruyoshi felt that these submarines were not enough to pose a threat to the American forces, so he gritted his teeth and sent the first submarine team out.

If the strength of the Japanese 3rd and 7th submersible fleets is still slightly insufficient, then the strength of the first submersible squadron is a bit scary.

Among them, the strength of the 7th Submarine Squadron is the worst, because all the submarines of this squadron are of the "Lu" type with a displacement of less than 1,000 tons; The strength of the third team is in the middle, and its submarines are all "Yi" type with a displacement of more than 1,000 tons; Team 1 is undoubtedly the strongest...... This can be seen from its "first" number. The first person in the army is often the originator of this service, which means that the most experienced and high-quality soldiers are basically concentrated in this team. Not only that, but this team also has one more dive team than other submarine teams, which means that it has 14 submarines.

In this way, Hyakutake Harukichi sent 36 submarines to the waters south of Kuah Island, and in order not to be discovered by the US military, they still advanced at night and entered the designated position to lurk and wait for fighters.

However, to the disappointment of the Japanese submarines, there were only a few enemy ships in the waters off Kuah Island...... They were tankers carrying supplies to Kuah Island and several destroyers escorting tankers.

The reason why there are only so many warships is because the US Navy admirals believe that air and sea supremacy in the waters of Kuah Island is already in the hands of the "Cactus" air force on Kuah Island, at least during the day. In addition, two aircraft carriers of the US Navy were injured and could not participate in the war. So only a few destroyers were sent out to show their faces and deal with the matter.

Rear Admirals Fukuyama and Hayashi were in charge of commanding the Japanese submarines, and under the guidance of his unswerving implementation of Hyakutake Harukichi's tactical idea of mainly attacking U.S. warships, Rear Admirals Fukuyama and Hayashi thought ...... At this time, if he attacked the merchant ships and destroyers in front of him, which he considered "insignificant", he might be sure to sink them, but at the same time, it would also expose the plans of the Japanese submarine to ambush in this area, which would warn the US Navy and make them on guard, so Fukuyama and Hayashi ordered all submarines not to attack.

This was another mistake of the Japanese army in the use of submarines.

The most important thing about submarines is concealment. This characteristic dictates that the submarine must have sufficient autonomy, because the submarine is likely to be exposed to radio communication in the process of receiving orders or reporting to superiors. And this exposure, again, is fatal for the submarine.

Fukuyama and Hayashi's order was undoubtedly to allow US oil tankers to transport shiploads of supplies to Kuah Island. But as the Japanese Navy, Fukuyama and Hayashi certainly don't care about this, he only cares about whether he can destroy a few more American warships...... If you tell your colleagues that you have destroyed a few merchant ships when you go back, you are afraid that others will laugh at your big teeth.

As for whether the Sino-US coalition forces on Kuah Island will have stronger combat effectiveness because of the supplies, Fukuyama and Hayashi believe that this is a question for the Japanese Army to consider. There was no need for the Japanese Navy to pay for the suffering of the Japanese Army.

Fukuyama and Lin are also very patient, they have been lurking in the waters of Kuah Island for three days, and finally encountered a rare fighter.

It was the US aircraft carriers "Wasp" and "Hornet" patrolling the southeast of the Solomon Islands under the escort of more than 10 warships...... This is because the US Navy knew that one Japanese aircraft carrier had been sunk and two aircraft carriers were injured, but at this time, the US reinforcement fleet arrived one after another, which greatly increased the strength of the US Navy, and although the US aircraft carrier "Enterprise" needed major repairs because of its injuries. However, the "Wasp," which came to reinforce the island, filled this vacancy in time, so the US Navy felt that the time had come to fully control the waters of Kuah Island and completely block the Japanese army's transportation to Kuah Island.

What they didn't expect was that there was already a group of ferocious "wolves" waiting for them underwater.

A few nautical miles away from the US fleet, in the clear blue water and sky, a submarine slowly floated, poked out its periscope, and greedily looked at the military targets on the sea. The submarine was numbered "I-19" and belonged to the 1st Submarine Squadron of the 6th Fleet of the Combined Fleet of the Japanese Navy, and its captain Yaji Komatsu.

Sensing that the U.S. ship group was moving fast, Komatsu ordered the submarine to surface, so that it could pursue at full speed at a maximum speed of 20 knots, otherwise the submarine would always be able to follow the ass of the U.S. ship and would be thrown farther and farther away.

But Komatsu's action was very dangerous, because although it was evening, it was not yet dark, and once they were discovered by the U.S. military, it seemed that there was only one way to die.
