In mainland China, the Japanese 3rd, 6th, and 40th Divisions massed at Yueyang and advanced southward in three columns and crossed the Xinqiang River, and tried again to cross the Miluo River to reach Changsha. In January 1942, Chinese forces got a victory at Changsha which was the first Allied success against Japan.
After the Doolittle Raid, the Japanese army conducted a massive sweep through Zhejiang and Jiangxi of China, now known as the Zhejiang-Jiangxi Campaign, with the goal of searching out the surviving American airmen, applying retribution on the Chinese who aided them and destroying air bases. This operation started on 15 May 1942 with 40 infantry battalions and 15–16 artillery battalions but was repelled by Chinese forces in September. During this campaign, The Imperial Japanese Army left behind a trail of devastation and had also spread cholera, typhoid, plague and dysentery pathogens. Chinese estimates put the death toll at 250,000 civilians. Around 1,700 Japanese troops died out of a total 10,000 Japanese soldiers who fell ill with disease when their own biological weapons attack rebounded on their own forces.
On 2 November 1943, Isamu Yokoyama, commander of the Imperial Japanese 11th Army, deployed the 39th, 58th, 13th, 3rd, 116th and 68th divisions, a grand total of around 100,000 troops, to attack Changde of China. During the seven-week Battle of Changde, the Chinese forced Japan to fight a costly war of attrition. Although the Japanese army initially successfully captured the city, the Chinese 57th division was able to pin them down long enough for reinforcements to arrive and encircle the Japanese. The Chinese army then cut off the Japanese supply lines, forcing them into retreat, whereupon the Chinese pursued their enemy. During the battle, in an act of desperation, Japan used chemical weapons.
In the aftermath of the Japanese conquest of Burma, there was widespread disorder in eastern India, and a disastrous famine in Bengal, which ultimately caused up to 3 million deaths. In spite of these, and inadequate lines of communication, British and Indian forces attempted limited counter-attacks in Burma in early 1943. An offensive in Arakan failed, while a long distance raid mounted by the Chindits under Brigadier Orde Wingate suffered heavy losses, but was publicized to bolster Allied morale. It also provoked the Japanese to mount major offensives themselves the following year.

Answer: Xinqiang River

Question: What is the river that the 40th, 3rd, and 6th Japanese divisions tried crossing to reach Changsha?

The Battle of Leyte Gulf was arguably the largest naval battle in history and was the largest naval battle of World War II. It was a series of four distinct engagements fought off the Philippine island of Leyte from 23 to 26 October 1944. Leyte Gulf featured the largest battleships ever built, was the last time in history that battleships engaged each other, and was also notable as the first time that kamikaze aircraft were used. Allied victory in the Philippine Sea established Allied air and sea superiority in the western Pacific. Nimitz favored blockading the Philippines and landing on Formosa. This would give the Allies control of the sea routes to Japan from southern Asia, cutting off substantial Japanese garrisons. MacArthur favored an invasion of the Philippines, which also lay across the supply lines to Japan. Roosevelt adjudicated in favor of the Philippines. Meanwhile, Japanese Combined Fleet Chief Toyoda Soemu prepared four plans to cover all Allied offensive scenarios. On 12 October Nimitz launched a carrier raid against Formosa to make sure that planes based there could not intervene in the landings on Leyte. Toyoda put Plan Sho-2 into effect, launching a series of air attacks against the U.S. carriers. However the Japanese lost 600 planes in three days, leaving them without air cover.

Question: What did Nimitz favor blockading?
Answer: Philippines

Thus, only in 1944 did the U.S. Navy begin to use its 150 submarines to maximum effect: installing effective shipboard radar, replacing commanders deemed lacking in aggression, and fixing the faults in the torpedoes. Japanese commerce protection was "shiftless beyond description,"[nb 14] and convoys were poorly organized and defended compared to Allied ones, a product of flawed IJN doctrine and training – errors concealed by American faults as much as Japanese overconfidence. The number of U.S. submarines patrols (and sinkings) rose steeply: 350 patrols (180 ships sunk) in 1942, 350 (335) in 1943, and 520 (603) in 1944. By 1945, sinkings of Japanese vessels had decreased because so few targets dared to venture out on the high seas. In all, Allied submarines destroyed 1,200 merchant ships – about five million tons of shipping. Most were small cargo-carriers, but 124 were tankers bringing desperately needed oil from the East Indies. Another 320 were passenger ships and troop transports. At critical stages of the Guadalcanal, Saipan, and Leyte campaigns, thousands of Japanese troops were killed or diverted from where they were needed. Over 200 warships were sunk, ranging from many auxiliaries and destroyers to one battleship and no fewer than eight carriers.

On 20 October 1944 the U.S. Sixth Army, supported by naval and air bombardment, landed on the favorable eastern shore of Leyte, north of Mindanao. The U.S. Sixth Army continued its advance from the east, as the Japanese rushed reinforcements to the Ormoc Bay area on the western side of the island. While the Sixth Army was reinforced successfully, the U.S. Fifth Air Force was able to devastate the Japanese attempts to resupply. In torrential rains and over difficult terrain, the advance continued across Leyte and the neighboring island of Samar to the north. On 7 December U.S. Army units landed at Ormoc Bay and, after a major land and air battle, cut off the Japanese ability to reinforce and supply Leyte. Although fierce fighting continued on Leyte for months, the U.S. Army was in control.

On the second day, U.S. reconnaissance planes located Ozawa's fleet, 275 miles (443 km)[citation needed] away, and submarines sank two Japanese carriers. Mitscher launched 230 torpedo planes and dive bombers. He then discovered the enemy was actually another 60 miles (97 km)[citation needed] further off, out of aircraft range (based on a roundtrip flight). Mitscher decided this chance to destroy the Japanese fleet was worth the risk of aircraft losses due to running out of fuel on the return flight. Overall, the U.S. lost 130 planes and 76 aircrew; however, Japan lost 450 planes, three carriers, and 445 aircrew. The Imperial Japanese Navy's carrier force was effectively destroyed.

The battle secured the beachheads of the U.S. Sixth Army on Leyte against attack from the sea, broke the back of Japanese naval power and opened the way for an advance to the Ryukyu Islands in 1945. The only significant Japanese naval operation afterwards was the disastrous Operation Ten-Go in April 1945. Kurita's force had begun the battle with five battleships; when he returned to Japan, only Yamato was combat-worthy. Nishimura's sunken Yamashiro was the last battleship in history to engage another in combat.

From early 1944 until the days leading up to the invasion, Kuribayashi transformed the island into a massive network of bunkers, hidden guns, and 11 mi (18 km) of underground tunnels. The heavy American naval and air bombardment did little but drive the Japanese further underground, making their positions impervious to enemy fire. Their pillboxes and bunkers were all connected so that if one was knocked out, it could be reoccupied again. The network of bunkers and pillboxes greatly favored the defender.
