On April 2, the first division of the American army began to advance eastward to cut off the Japanese lines. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 On April 4, the 24th year of the first year of the first year, two U.S. Marine Divisions crossed the entire island to Nase Bay on the east coast, occupied the central part of the island, and split the Japanese defense line in two. The mission that the US military originally planned to complete in 15 days was successfully completed in only four days.

When the US troops landed on Okinarabu Island on 26 March, the Japanese army judged that the US landing on the Amami Islands had already begun, and Vice Admiral Toyoda, commander of the Combined Naval Fleet, immediately ordered the "Operation Ten," but the shore-based air force of the Navy's Fifth Air Fleet stationed in the Kyushu area, which is the main force of the "Operation Ten," immediately ordered the "Operation Ten," but on 18 March, the shore-based air force of the Navy's Fifth Air Fleet stationed in the Kyushu area, On the 19th, the U.S. Army suffered heavy losses in the air raid on the Kyushu area, and was no longer able to organize a large-scale operation. Most of the other aviation units of the Navy were still in training, and the army's air force had not yet had time to be transferred to Kyushu, so the Japanese army only dispatched a small number of aircraft to attack.

From 26 to 31 March, only 100 sorties, including reconnaissance planes, were dispatched, including about 20 suicide sorties. Although the "Sky Operation" ended hastily, although the number of suicide planes that attacked was small, it still caused certain losses to the US military. On 31 March, the heavy cruiser "Indianapolis," the flagship of Spruance of the US Fifth Fleet, was hit by a Japanese suicide plane, and two large holes were knocked out of the hull. By 5 April, the Japanese had sunk one fast transport ship and damaged 39 ships of various types, including 2 battleships, 1 escort aircraft carrier, and 3 cruisers.

On 6 and 7 April, the Japanese army dispatched 462 naval planes and 237 army planes, a total of 699 aircraft, including 355 suicide planes, with the Fifth Air Fleet and the Sixth Air Force in Kyushu as the main forces and the First Air Fleet and the Eighth Flying Division of the Shikoku and Sakishima Islands as auxiliary forces. They sank three US destroyers, one tank landing ship, and two 10,000-ton munitions ships, and damaged one battleship, one aircraft carrier, one frigate, one mine-laying ship, and eight destroyers, and the US forces suffered hundreds of casualties. The Japanese called the two-day battle "Kikusui No. 1" operation, and a total of 335 Japanese planes were shot down, accounting for about 48% of the total number of sorties.

On April 12 and 13, the Japanese army launched the "Kikusui No. 2" operation, because the planes lost in the "Kikusui No. 1" operation had not had time to replenish, so the number of planes in the sortie was less than the first time, the navy dispatched 200 planes, the army 192 planes, a total of 392 planes, including 202 suicide planes. Due to the lack of troops, the Japanese army made some improvements in attack tactics, first dispatching fighter planes to attract US fighters, and when the US fighters ran out of fuel and returned to the mother ship, the attack planes flew over the target to attack; at the same time, the Japanese army also began to use a new type of weapon -- "cherry blossom bombs," which were actually rocket-boosted manned aerial bombs, which were carried by attack planes to the theater of operations and then separated from the carrier planes, and were piloted by the daring pilots to rush to the target, loaded with a ton of high bombs, propelled by three solid-fuel rocket engines. The speed is as high as 800 kilometers per hour, and it is very powerful, and the US military calls it "eight-grid bullets", and this weapon has caused considerable losses to the US military. In this operation, the Japanese sank one US destroyer and one landing ship, damaged one battleship, six destroyers, three frigates, one minesweeper, one mine-laying ship, and one landing ship, and lost 205 planes. Beginning in mid-April of the 24th year of the Taichu Dynasty, in order to reduce losses, the US military dispatched radar warning ships in the direction where the Japanese planes were most likely to come. In addition, a large number of fighter planes were deployed on the newly occupied Oshima airfield, which was specially designed to intercept the invading Japanese planes.

On 16 April, the Japanese army launched the "Kikusui III" operation, dispatching 391 naval planes and 107 army planes, a total of 498 planes, including 196 suicide planes, sinking 1 transport ship and 1 munitions ship, damaging 1 aircraft carrier, destroyer, and hospital ship, 2 transport ships, and losing 182 Japanese planes. In this battle, the US destroyer USS Lafite fought bloody battles and won the honor of "unsinkable ship" and became a symbol of the bravery and strength of the US Navy. At about 8 o'clock in the morning, when it discovered that more than 50 Japanese planes were approaching, the "Rafi" immediately issued an early warning and guided the fighters in the air to intercept it. Soon two Japanese suicide planes rushed over, and the "Lafite" quickly opened fire and shot it down, and then more than 20 Japanese planes pounced from several directions, and the "Lafite" went all out to organize the whole ship's firepower to shoot at the air, and the Japanese planes concentrated on the attack, making it difficult for the "Lafite" to take care of both, and was hit by three suicide planes one after another, one of which was hitting the turret of the 127 mm tail gun, and the violent explosion blew up the turret on the spot, and flames and smoke gushed out, up to 60 meters. The deck was littered with burning caused by jet fuel spills on Japanese suicide planes, and the fire was raging, and the damage management team fought to the death to control the spread of the fire. Immediately after that, a bomb dropped by a Japanese plane hit the ammunition compartment of the 20-mm anti-aircraft gun, causing an even larger explosion that blew up the steering gear and deprived the "Rafite" of its ability to maneuver. Soon two more suicide planes crashed into the "Lafite", which further aggravated the injury, the guns of the second half of the "Lafite" were all blown up, only the four 20-mm guns in the front were still insisting on fighting, the life-and-death struggle lasted for a full 80 minutes, the "Lafite" was attacked by a total of 22 suicide planes, shot down nine, but was hit by five, and four bombs hit, the "Lafite" was so traumatized that with the efforts of all the crew, it did not sink in the end, and among the 350 crew members, 32 people died, 71 people were injured, almost a third. The next day, it was towed by a tugboat to the Okinagabu Island anchorage for emergency repairs. On April 22, the 24th year of the first year of the first year, he was able to sail to Guam under the power of repair, and finally sailed to the mainland of Seattle on May 22, 24th year, and carried out major repairs at the Todd shipyard, until the end of the war with Japan on September 6, and even in the subsequent wars.

The Japanese army's three Kikusui operations were all carried out during the day, although it was easy to find the US military targets, and many results were achieved, but the cost was also quite huge, for the Japanese army, whether it was the loss of planes or pilots, it was difficult to quickly replenish, so the subsequent Kikusui operation, the Japanese had to change to a night attack. On April 21 and 22, the Japanese army dispatched 317 planes, including 131 suicide planes, to carry out the "Kikusui No. 4" operation. On 4 and 11 May, in order to make up for the loss of planes, the Japanese army converted its water reconnaissance planes into suicide planes and launched a special attack, dispatching a total of 597 planes, including 300 suicide planes, and successively launched the Kikusui 5 and Kikusui 6 operations.

On 24 and 25 May and 27 and 28 May, the Japanese army converted its trainer planes into special attack planes in order to increase the number of special attack planes, and launched the Kikusui 7 and Kikusui 8 operations one after another, dispatching a total of 737 aircraft, including 208 suicide planes. On June 3, 21 and 22, the Japanese army did its best to dispatch 502 aircraft, including 114 suicide planes, to launch the Kikusui 9 and Kikusui 10 operations.

From 6 April to 22 June, the total number of sporadic sorties was as high as 4,109 sorties, including 917 suicide planes, plus 10 sorties of planes dispatched during the Kikusui operation, totaling 7,851 sorties, of which 2,423 were suicide planes, and although more than 4,200 were shot down, they caused huge losses to the US military, sinking 33 US warships and damaging more than 360 ships. Of the 33 warships sunk by the U.S. military, 26 were sunk by suicide planes, accounting for 78.8 percent of the total number of sunken warships. Even Mitchell's flagship "Bunker Hill" aircraft carrier was hit by two suicide planes in the Kikusui 6 operation launched by the Japanese army on May 11, 24 years of Taichu, and the damage was extremely serious, with 396 crew members killed and missing, and 264 wounded, one of the suicide planes crashed into the engine when the engine exploded when it flew into the cabin where Mitchell's headquarters was located, killing 14 staff officers in the cabin on the spot, Mitchell had to lead the rest of the personnel of the headquarters to transfer to the new "enterprise" aircraft carrier, but three days later, the new "enterprise" The ship was also hit by a suicide plane and lost its ability to sail, leaving Mitchell to change flagships twice in three days. In contrast, the four aircraft carriers of the British army participating in the war were all hit by the Japanese suicide planes, but the damage was far less than that of the US military, because the British aircraft carriers had an armored flight deck and a sturdy closed hangar structure, so the ability to resist damage and impact was much stronger than that of the US aircraft carriers.

After the First Battle of Leyte Gulf, the main force of the Japanese Navy's Combined Fleet had been lost in half, and the remaining surface ships were withdrawn to Brunei and reorganized into the Second Fleet, with Vice Admiral Ito Junichi replacing Keno Kurita, who had been removed due to a major command mistake in the Battle of Leyte Gulf, as commander, and returned to Kure Harbor on the Japanese mainland on November 24. On 17 March, judging that the landing of US forces on Okinawa was imminent, the Combined Fleet ordered the Second Fleet to move forward to the Tokuyama anchorage in the western part of the Seto Inland Sea and be ready to attack at any time.

On 5 April, the Combined Fleet decided to form a special attack force at sea with the Second Fleet's battleship "Yamato" and cruiser "Yaji" and eight destroyers, including "Fuyutsuki", "Suzuki", "Isokaze", "Hamaze", "Yukikaze", "Asaka", "Kasumi", and "Hatsushuang", to cooperate with the "Kikusui No. 1" air special attack operation, and to break into the waters west of Okinawa at dawn on 8 April 24, Taichu to annihilate the US landing formation and support the defenders on Oshima in recapturing the airfield. Due to the serious shortage of fuel for the Japanese army, the Combined Fleet took great efforts to collect 2,500 tons of fuel, which was less than half of the 6,400 tons of fuel tank capacity of the "Yamato," which could barely guarantee the fuel consumption required for a one-way trip to Okinawa. Many people can't help but feel a little out of shape, which is completely different from the scene of talking and laughing at the farewell drink before the expedition, full of pathos and sadness before death.
