Longling County, Baoshan, Yunnan, has a place called Songshan. Songshan is the first peak of Longling County. The terrain is dangerous and easy to defend. It is known as the "Gibraltar" in the East. The famous Songshan Battle is here. The Battle of Songshan, an important part of the Battle of northern Simeon and one of the largest in southern China, is called the Battle of Songshan as the "Jade Broken War" on the Asian battlefield of World War II, that is, the whole army was destroyed. In May 1942, after the Japanese invaded China and entered the Nu River, Songshan was used as a war preparation center, offensive stronghold and defensive support point. In 1943, the Japanese army recruited more than 1,600 people to build fortifications in Songshan, day and night construction. In February 1944, after the fortification was completed, in order to keep it secret, the Japanese army executed all the people in the name of fighting an epidemic prevention needle and burned their bodies to burial. After the war, a "thousand-person pit" was found at Dagukou. In June 1945, the Battle of Songshan began. In the course of 95 days in three months, ten battles were launched, which ended with our victory and opened the curtain of China's anti-Japanese offensive.

At that time, the Japanese army was hiding in such a bunker, disguised outside, and it was difficult to find the ground and air. After the artillery bombardment, the Japanese army drilled out of the bunker like a mouse and went crazy. Figure 7, the main battlefield relics of the manger depression. On August 20, 1944, after the expeditionary army captured the main peak of Songshan, the Japanese army was unwilling to fail, and organized a death squad to fight wildly. The expeditionary army fought hard, fought melee with the enemy, and finally held its position. After cleaning up the scene, the enemy and us both tangled and bitten, and there were 62 pairs in the trenches of the soldiers who died together. The positions were dissociated and the intestines and lungs were in disarray. The hand and foot, ears, eyes and intestines were everywhere, and the scene was very appalling. The descendants called this mountain, called the "melee mountain". More than 680 expeditionary troops lost their lives here, and the real "every inch of land is soaked in blood".
