At this moment, the 2nd Division and the 12th Division of the Japanese Army began to move towards the outer positions of Dalian, waiting for the Japanese Combined Fleet to defeat the main force of the Beiyang Naval Division, and with the support of naval artillery, they re-attacked Dalian defended by the Dingbei Army!

In the waters of Jinzhou Bay, when the 3 detachments of the naval fleet of the Naval Academy of the Naval Academy with a total of 21 main warships and the 28 main warships of the Japanese Combined Fleet were 5,500 meters apart, the four ironclad battleships of the First Battlefleet of the Combined Fleet formed a battle line and fired at the naval fleet of the Naval Academy with the 12 main guns on the 4 ironclad battleships!

Immediately, Lin Daxin ordered the First Fleet, which had already formed a battle line, 6 ironclad battleships and 24 main guns to fire at the combined fleet! It was 10 a.m. on March 15, 1895!

The other warships on both sides also fired at each other after their respective ironclad battleships opened fire.

The submarines Bayonet and Sharp Knife, after the start of an artillery battle between the two sides, sneaked under the water and went around the rear of the Japanese Combined Fleet. The two submarines used some torpedoes in the battle against the Italian expeditionary fleet, and now have a total of only 16 533 mm conventional battery-powered torpedoes and eight 400 mm conventional battery-powered torpedoes.

There are no other old-fashioned torpedoes of these two models in the ammunition depot of the Navy in the Navy Academy, so the two submarines currently only have 2 models of 24 torpedoes purchased by Lin Daxin from modern time and space, but Lin Daxin believes that even these 24 torpedoes will definitely bring very big losses to the Japanese Combined Fleet!

When the two fleets were 5,000 meters apart, the naval fleet of the Naval Academy first achieved results, a 450 mm shell fired from the main gun of the Flying Wolf ironclad battleship hit the waterline armor of the old ironclad ship Chunfeng with a displacement of 6,100 tons, and the more than 200 mm waterline armor of the old ironclad ship Chunfeng could not withstand the 450 mm shells at all, and after the shell penetrated the armor, an explosion occurred in the Chunfeng ship.

The explosion detonated the boiler and ammunition compartment of the Chunfeng at once, and after a loud explosion, the old ironclad ship of the Invincible class sold by Britain to Japan, with all 340 Japanese naval officers and sailors, sank to the bottom of the sea. The Spring Breeze became the first warship to be sunk by the Japanese Combined Fleet in this naval battle.

Just after the start of the war, the Japanese Combined Fleet lost a warship, which made the commander of the Combined Fleet, Ito Yuxiang, tremble in his heart, he knew in his heart that although the British sold many warships to Japan, most of them were some very backward old warships, although the firepower of the guns on the warships was okay, but the very slow speed could make the enemy aim lightly, and it was easy to become a live target!

Just after the Chunfeng sank, a huge explosion was heard on the sea, and the Japanese armored cruiser Mogami with a displacement of 5,670 tons was hit by the 260-mm main gun of the Navy Admiral of the Naval Academy, and one of the 254-mm guns of the Mogami was blown up, and several 254-mm shells of this main gun were detonated.

The detonation of several 254-mm shells blew up the entire front half of the Mogami, and the other 254-mm main gun and four 228-mm secondary guns in the first half were scrapped, which not only caused a fire, but also the front half of the hull began to seep water, although the Mogami was not directly sunk, but almost lost most of its combat effectiveness.

Commander Ito Yuki immediately ordered Mogami to break away from the formation and retreat to the back sea first, first extinguishing the fire.

Shells from both sides were constantly weaving on the surface of the sea, flying towards each other's warships.

When the two fleets were 4,500 meters apart, a main gun shell from the Japanese ship Zuizuru ironclad battleship hit the 7,935-ton old ironclad ship Dinghai of the Lushun garrison fleet, which not only blew up two 260-mm main guns in the bow of the ship, but also caused a skyrocketing fire.

The commander of the Lushun garrison fleet, the original chief instructor of the Sailor School, Xi Yu Fu, saw the Dinghai ship on fire, and said dejectedly to the naval officers and soldiers in the bridge of the Weihai, the flagship of the garrison fleet: "The old man was entrusted with a heavy task by my Daxin nephew, and he didn't expect that there would be no results, so he seriously injured a big ship first!" Tell the Dinghai, retreat back, wait for the fire on the ship to be extinguished, and then return to the battlefield! ”

Yu Fu then slapped the table in the bridge again, and said loudly: "Sue the gunners of the ships of the Lushun garrison fleet, and aim at the old man!" Play the majesty of our Lushun garrison fleet! In this way, the old man has the face to open his mouth to Daxin's nephew, and strive to get more warships for our garrison fleet! ”

Yu Fu's words were not in vain, and after a while, the shells fired from the 305-mm main gun of the Weihai, the flagship of the garrison fleet, hit the medium armored cruiser Matsushima, which had a displacement of 4,278 tons, the flagship of the former Japanese Combined Fleet.

The 305-millimeter shell directly penetrated the waterline armor of the Matsushima, exploded in the hull, and detonated the ammunition compartment of the Matsushima, and the power of the explosion blew the Matsushima in two at once, sinking into the sea, becoming the second warship sunk by the Japanese Combined Fleet. None of the more than 350 Japanese naval officers and sailors aboard the Matsushima survived.

At this time, the submarine Bayonet and the Sharp Knife submarine had already sneaked around the side of the Japanese Combined Fleet, and the captain of the Bayonet, Zhang Bin, ordered to raise the periscope, and immediately discovered that there was an ironclad ship of nearly 10,000 tons directly opposite his submarine, and immediately ordered: "No. 1 torpedo tube is loaded with water!" Ready to launch! ”

After a while, news came from the torpedo launch room that the No. 1 launch tube was ready!

Zhang Bin ordered: "The target is ahead!" The distance is 1550 meters! Torpedo No. 1 launched! "Originally, according to the submarine operation procedures, there should be at least two torpedoes for one target each time, so as to increase the hit rate and increase the damage range! But now the torpedo on the submarine is insufficient, and Zhang Bin chose a single torpedo attack! Although it was a single-shot torpedo attack, Zhang Bintong's battle with the Italian expeditionary fleet made him very confident in the new torpedo that Lin Daxin bought!

The 533 mm battery-powered torpedo flew towards the target at a high speed of 50 knots, and with a loud bang, the torpedo accurately hit the Japanese ship's 9,700-ton old ironclad ship Hakaze.

The 533 mm torpedo instantly transferred from the fragile underwater armor of the Feather into the hull, and the explosion of the torpedo not only blew up a big hole under the waterline, but also blew the bottom of the Feather to smash, and the sea water instantly poured into the Feather, and it didn't take 5 minutes for the old ironclad ship with a displacement of nearly 10,000 tons sold by the British to Japan to sink into the sea, becoming the third warship sunk by the Japanese Combined Fleet.

Shortly after the bayonet fired the torpedo, the Sharp Knife also fired a 533mm battery-powered torpedo at the old ironclad ship Matsukaze, which was of the same model as the Feiyu. Although this torpedo did not directly sink the Matsukaze, it blew up a large hole of about 3 meters underwater for the Matsukaze, which had a speed of only 10 knots, and the speed of the Matsukaze was reduced to 5 knots.

Then the Matsukaze was hit by several large-caliber shells in succession, and the resulting fire detonated the shells in the ammunition compartment, and after a violent explosion, it sank into the sea, and less than 200 of the 540 Japanese naval officers and sailors on board escaped. The Matsukaze became the 4th Combined Fleet warship to sink.

Many of the officers and men on the warships of the Japanese Combined Fleet are naval reservists, graduates of naval schools, and newly recruited naval personnel, and this naval battle can be said to be their first time participating in actual combat; less than half an hour after the battle began, the Combined Fleet sank four warships, which made these rookies of the Japanese Navy can't help but begin to panic, and the hit rate of artillery fire is even lower!

The commander of the Combined Fleet, Ito Yuxiang, saw the sudden and inexplicable explosion of two old ironclad ships, and suddenly thought of the inexplicable defeat of the Italian expeditionary fleet in the hands of the Beiyang Naval Division, and was thinking about what was going on, when a Japanese Navy Major ran to Ito Yuxiang and said quickly: "Commander, before the Matsukaze sank, a flag was sent that the Matsukaze was hit by a torpedo first in the underwater part!" It was reduced to 5 knots before it was continuously sunk by large-caliber shells! The captain of the Matsukaze said that the enemy should have a submarine nearby! ”

After listening to this, Ito Yuxiang shouted in shock: "Submarine! No way! How could those gadgets get close to our warship and not be detected! ”

In Ito's impression, submarines must be within one or two hundred meters of the warship and rise to a position very close to the sea surface before they can launch torpedoes, and submarines are very easy to spot when they are close to warships.
