The main story about the Shuimen Bridge at Changjin Lake is: The 7th interleaving company should have 157 men, but actually there was one!"

At that time, due to the U.S. Land War, The First Division's retreat south to Xingnan Port must take the Shuimen Bridge. Therefore, theoretically speaking, as long as the Shuimen Bridge is completely blown up, the Ninth Corps of the Volunteer Army is very likely to completely annihilate the U.S. First Marine Division and draw a successful conclusion to the Battle of Changjin Lake. Regarding the strategic importance of Shuimen Bridge, Zhang Yixiang, commander of the 20th Army of the Volunteer Army, once said: "At Shuimen Bridge, as long as you give me a heavy artillery, not a single person from the 1st Marine Division can escape!"

But Shuimen Bridge The bridge is not a bridge in the ordinary sense, but the top of the spillway below the generator room of an abandoned hydropower station. It is not easy to blow up. The volunteer army team blew up the Shuimen Bridge three times, but it was repaired in time by the US military engineers. After the third bombing of the bridge, the U.S. military customized and airlifted 8 sets of steel components from Japan and dropped them with parachutes, allowing the 1st U.S. Marine Corps to escape.

This period of history has continued throughout the entire history. The War to Resist U.S. Aggression and Aid Korea may have been inconspicuous and not mentioned much in historical materials, but the Battle of Changjin Lake in the second battle almost changed the course of the battle and even the outcome of the entire war.

Shuimen Bridge. The battle is also part of the Battle of Changjin Lake. The "Ice Sculpture Company" that finally appears in the movie "Changjin Lake" is the story that happened in the Battle of Shuimen Bridge. It is also the most difficult and regrettable battle in the Battle of Changjin Lake.
