This value is measured according to the width of the broken bridge of Yalu River. Because it is impossible to consider the water level at that time, it can only be expressed in approximate terms, but the specific operational position is determined and can be judged according to the following historical records and existing sites:

1On June 25th, 950, a civil war broke out in North Korea, and the United States invaded North Korea, burning the war to the Yalu River, which seriously threatened China's security. At the request of the North Korean government, the CPC Central Committee and Chairman Mao made a wise decision: to resist US aggression and aid Korea and defend the country. 101October 19, Peng was ordered to lead Chinese people's Volunteer Army to cross the Yalu River, and the Yalu River Bridge became the traffic artery to resist US aggression and aid Korea and support the front line. Because this bridge had a very important strategic position in the War to Resist US Aggression and Aid Korea, the United States tried every means to destroy it. 1October 8th, 1950+ 165438, the U.S air force sent 100 more than B-29 bombers to bombard the bridge for the first time, and the bridge was intercepted by the waist, and the steel beam on the north side fell into the water. In the same year165438+1October 14, the US military sent 34 military bombers to bomb the bridge again, and three piers of the DPRK collapsed. So far, the bridge has been paralyzed, leaving four holes on the China side. Known as the Yalu River Broken Bridge, it became the historical witness of the War to Resist US Aggression and Aid Korea.

While the first bridge was blown up, the second bridge adjacent to it also suffered serious trauma. In order to protect the safety and smoothness of the bridge, the staff and garrison of Anton Railway Branch braved the constant harassment of enemy planes and the bombardment and strafe at any time, and went all out to repair the bridge, making the Yalu River Bridge an unbreakable steel transportation line. At the same time, the 3rd Battalion of 17 Regiment, 503rd Regiment and 13 Regiment, which belongs to the Air Defense Command of Anton Military Region, undertakes the guard task, forming a complete air defense system. From June 1950 to August 195 1, enemy planes attacked the Yalu River Bridge. The air defense forces guarded the bridge 2 19 times, shooting down 22 enemy planes and injuring 75. Although enemy planes dropped bombs on the river one after another, the hit rate dropped from 10% to below 7%, which effectively defended the safety of the Yalu River Bridge.

1On July 27th, 953, the American invaders signed the Korean Armistice Agreement, and the war to resist US aggression and aid Korea, which lasted for two years and nine months, ended successfully. 1958, Chinese people's Volunteer Army withdrew from North Korea and returned home from Yalu River Bridge. In front of the "Arc de Triomphe" at Daqiaotou, the people of Anton warmly welcomed the glorious volunteers. After the victory of the war, North Korea demolished the six-hole residual bridge of the first bridge, but our four-hole residual bridge proudly stood on the river with countless scars for people to mourn and remember the past.
