The war in western Yunnan lasted for several months, and Songshan and Longling could not be captured for a long time.

The expeditionary force attacking Longling fought very hard, and some divisions were almost completely defeated. The new 39th Division, including the division commander, had only more than 60 people left.

On 14 September, at the Sino-US joint meeting in Chongqing, Dou Enmian, head of the advisory group of the US Expeditionary Force, reported to the meeting on the orders of Wei Lihuang: The Western Yunnan Expeditionary Force has suffered 34,000 casualties, of which 85 to 90 percent are infantry, and some divisions are almost without infantry. The 56th, 2nd, and 18th divisions of the Japanese army concentrated in the Longling area and counterattacked the expeditionary force. Although the 200 divisions were replenished, they were still insufficient. Please send the 96th and 48th Divisions to reinforce western Yunnan.

Just this time, Xu Yongchang immediately replied to the opinion: "Weighing the stakes and harms, it is appropriate to not be transferred." Xu didn't give Wei Lihuang any face this time.

In fact, this was Chiang Kai-shek's opinion, and the chairman of the committee was reluctant to send more troops to western Yunnan.

At this time, the battlefield of Xianggui was in a mess, and in order to maintain the situation, he was ready to shrink the front and retreat to Jiangdong.

On September 15, Chiang Kai-shek sent a secret telegram to Wei Lihuang, commander of the expeditionary force, asking him to change his offensive to a defensive position: "First, the enemy in Burma seems to have transferred the main army to western Yunnan to reinforce it; 2. The expeditionary force should be prepared to change its position to a defensive position, to maintain contact with the enemy on the west bank of the Nu River, to firmly hold the key points of Tengchong and Songshan, and to withdraw the main force to the east bank of the Nu River to occupy the original position......

On this day, Chiang Kai-shek summoned Stilwell. As soon as Stilwell sat down, he could not wait to ask Stilwell in the tone of the Chinese generals to lead the Chinese army in India to launch an attack from Bamo within a week, so as to alleviate the resistance of the Longling side, otherwise he would order the expeditionary force to withdraw from the west bank of the Nu River to defend Kunming and the rear of the Nationalist Government.

Stilwell was taken aback when he heard this, Songshan and Tengchong had just been recaptured from the Japanese army, how could they give up lightly with how many soldiers shed blood and sacrificed! He silently looked at the dictator in front of him, his heart full of contempt. Looking at Chiang Kai-shek's shiny bald head, he couldn't help but scold: Peanuts!

Since the arrival of the Indian troops at Myitkyina airport on 15 May, the conditions for the transportation of US supplies to China have been greatly improved. Outside the Hump route, Myitkyina airport can take off and land, and supplies to China are gradually increasing. Unexpectedly, Chiang Kai-shek, who had received more funding, said that he would abandon Longling and retreat to the east of the Nu River, which is really incredible. In that case, the Allied efforts would not have been in vain.

The scene of the bloody battle between the troops stationed in India and the Japanese army seems to have been just yesterday.

The Menggong River Valley is a dangerous terrain, and the Nangao River, which runs north-south, splits the valley in half. The two important towns of Gamai and Menggong in the valley face each other across the river, facing each other in attack and defense, and are horns of each other. After consulting with the Chinese generals, Stilwell made a bold operational deployment: the new 22nd Division advanced to attack Gamai; The new 38th Division detoured to Meng Gong along the left side of Gamai; In addition, the US Galahad commando unit and the 88th Regiment of the 30th Division and the 150th Regiment of the 50th Division, which had just arrived at the front line, formed a Sino-US joint commando team, which made a detour through the lofty mountains and mountains on the north side and inserted itself into Myitkyina, a strategic point behind enemy lines. The Japanese army was divided and surrounded on the line of Myitkyina, Mong Gong, and Kamai, and annihilated.

On April 24, 1944, the new 22nd and 38th divisions advanced to their respective targets. On the 28th, the Sino-US joint commando secretly marched from Dakeri in the Hukang River Valley to Myitkyina. On May 14, Stilwell finally received a signal from the U.S.-China joint commando that they were still 48 hours away from Myitkyina. Two days later, the force covertly approached the outskirts of Myitkyina. Myitkyina is an important town in northern Myanmar, with convenient transportation and dangerous terrain. In early March, the 18th Division of the Japanese Army, after being reinforced by the 56th Division, defended Myitkyina with the main force of one wing, and guarded Meng Gong in the direction of Ruili and Leibang with the other.

In the early morning of 17 May, the US military dispatched a large number of planes to bomb Myitkyina for a long time. At 10 a.m., the Sino-American joint commando launched a fierce attack on the airfield about 1 kilometer west of Myitkyina. The Japanese army was at a loss for the sudden arrival of Chinese and American troops and put up a hasty resistance. After 4 hours of fighting, the Chinese and American forces completely cleared the airfield of the enemy and sent the famous signal "Merchant of Venice" to the command. In the afternoon, transport planes and gliders loaded with weapons, ammunition, supplies and reinforcements landed at Myitkyina airport. The next morning, Stilwell flew to Myitkyina with 12 war correspondents. Immediately, the news of the "surprise attack by the Allied forces to occupy Myitkyina" quickly spread to the Allied powers. When Churchill learned that the Chinese and American troops had suddenly occupied Myitkyina airfield, Churchill immediately asked Mountbatten, commander of the British Southeast Asian Theater of Operations, "How did they fall from the sky in Myitkyina, and what is your explanation for this?"

The initial victory in Myitkyina cut off the enemy's logistical supply lines at Mong Kung and Kamai, and greatly encouraged the new 22nd and 38th divisions to attack the Japanese frontally. At the end of May, the new 38th Division surrounded the enemy in Valan, and the main force quickly advanced in the direction of Meng Gong. June 1. The new 22nd Division captured the Malan Heights and immediately developed an offensive towards Gamai. On the 16th, the new 22nd Division occupied Gamai and annihilated most of the enemy, and the commander of the 18th Division, Tanaka Shinichi, led more than 3,000 remnants of the army, and fled south in a hurry under the main force of the 53rd Division. On June 25, the new 38th Division conquered Menggong and annihilated more than 1,600 enemies.

However, the battle to capture the city of Myitkyina was very hard. Due to intelligence errors, after the Sino-US joint commandos occupied Myitkyina Airport, they mistakenly thought that the Japanese defenders were only more than 300 people, and the commander, Brigadier General Merrill, only sent two battalions of the 150th Regiment to attack the Japanese army, losing the best opportunity to attack, and the Japanese army hurriedly dispatched troops to Myitkyina for reinforcements, so that the Japanese troops in the area quickly increased from more than 3,000 to more than 5,000. Stilwell successively airlifted the 41st and 42nd regiments of the 14th Division, the 89th and 90th regiments of the new 30th Division, and the 149th Regiment of the 50th Division to Myitkyina. The units constantly launched onslaught against the Japanese army. But the Japanese army, with its strong fortifications, stubbornly resisted.

The rainy season in northern Myanmar affected the landing of planes, and American gliders carrying Chinese troops were often hit by Japanese troops, and blood flowing from the cabin stained the leaves and grass at the airfield. The Chinese army can only advance inch by inch. The 150th Regiment once captured Myitkyina Railway Station, but was lost in the Japanese counteroffensive.

Along the muddy road, a day's strong attack by the Chinese army was not enough to push the front forward by 200 meters. Sometimes the positions captured during the day were recaptured by the Japanese at night by surprise attacks from the tunnels. Rains and floods turned the lowlands of Myitkyina into swamps and swamps into oceans. The fighters were greatly attritional, and the battle was in a stalemate. General Stilwell was helpless.

After July, the enemies of Mon Gong and Gamai were annihilated, and Myitkyina became an isolated city. However, the commander of the Japanese army, Major General Minakami Genzo, in accordance with the order to "defend Myitkyina to the death", still resisted stubbornly and fought the trapped beasts. The Chinese and American coalition forces adjusted their deployment, besieging Myitkyina from three sides with the 50th Division, the new 30th Division, and the U.S. Lagahad commando.

On July 7, on the 7th anniversary of the outbreak of the War of Resistance Against Japan, Zheng Dongguo, Sun Liren and other generals on the Myitkyina front issued a general attack order to the Chinese army. Under the cover of U.S. bombers and new rocket artillery, the Chinese army once again captured the Myitkyina railway station and, together with the U.S. military, formed a three-sided encirclement of the city. The Japanese positions were devastated, the trenches were filled with rainwater, and the Japanese soldiers were soaked in waist-deep water, desperately resisting.

On July 18, Chinese and American troops moved into street fighting in Myitkyina, searching alley by alley and house by house, and on August 1, they captured seven main streets in Myitkyina, and the Japanese army was compressed to the last position in the north of the city. In the afternoon of the same day, Major General Pan Yukun, commander of the 50th Division, recruited a "decisive battle death squad." The officers and men signed up one after another, and even the heralds, ordnance soldiers, and men of the headquarters all asked for the opportunity to repay the country with death. Late at night on August 1, a Chinese "death squad" composed of 104 people, led by local overseas Chinese, braved the rain to go around the back of the Japanese army. In the early morning of the next day, the "death squads" and the frontal troops launched an attack at the same time, and the Japanese troops were attacked on their backs, and their will finally collapsed, except for the Japanese soldiers who were killed and wounded in the position, the other remnants fled from the trenches in panic, and only 4 or 500 people crossed the Irrawaddy River on bamboo rafts and swam water, and retreated in the direction of Bamo. The supreme commander of the Japanese army in Myitkyina, Mizumi Genzo, was forced to commit suicide by pulling out a gun under a large tree by the river.

In this battle, more than 2,000 Japanese soldiers were killed, more than 70 people were captured, and more than 6,000 Chinese and American allied troops were killed or wounded and sick due to the war, including 1,244 soldiers (272 US troops and 972 Chinese troops). After 80 days of arduous and fierce fighting, the precious lives of countless soldiers of the Chinese army stationed in India were exchanged for a victory of strategic significance in the entire Asian theater.

The recovery of Myitkyina marked a decisive victory for the Allied forces in the Battle of Northern Burma, and the initiative on the Burma battlefield was transferred to the Allied forces. For China, this means that the connection between the China-India Highway and the Yunnan-Burma Highway, two blocked transport routes, is just around the corner, and the dangerous "Hump Route" will go down in history, and the air force can fly to Kunming and Chongqing from safer and more convenient routes in the southeast; The strategic situation in southwest China has fundamentally changed, and the rear of the anti-Japanese resistance has truly gained a sense of stability; The Japanese occupation of Burma was only a handful, and its all-out offensive on the Asian continent evolved into a defensive defense, and finally collapsed completely. The battle (Mong Gong Valley and Myitkyina Campaign) dealt a devastating blow to the Japanese ace 18th Division and other units, annihilating more than 20,000 Japanese troops, and the Chinese Expeditionary Force was humiliated by the defeat of Burma two years ago. Immediately after the victory, Liao Yaoxiang sent a telegram to Chiang Kai-shek and excitedly said: "The huge loss of the enemy's heavy weapons and military vehicles this time, the number of casualties, and the number of people who have been killed and wounded and sick have been transferred to the ravines, and the miserable situation of the collapse is even worse than the Nationalist army's transformation into the savage mountain two years ago." Looking back at the past and seeing the present, the officers and soldiers are ashamed of the past, and the officers and soldiers are very excited. ”
