What is the background of Watergate Bridge in Changjin Lake?

The historical background of Watergate Bridge in Changjin Lake is:

1950165438+1October 30th, Smith finally officially issued the evacuation order. In the snow, the US military began to retreat to the south desperately, trying to jump out of the "pocket" laid by the volunteers. From Liutanli, Li Xinxing, Xiajieli and Gutturi, there are ambushes and snipers of China Volunteers everywhere.

During the day, under the cover of planes and tanks, the American army launched a storm and made a desperate breakthrough to the south. At night, the volunteers took advantage of the night to counterattack the assault, recapture the highlands and positions lost during the day, and then try their best to stop the American attack after dawn. On the fiercest day of the fighting, the American troops only retreated 500 meters all day.

It was 1 950,65438+February,1,and the day before the polar bear regiment was annihilated by the organizational system, Smith learned that the Watergate Bridge on their way back was blown up by our army. On February 6th, 65438, Jiang Qingyun received the task: at all costs, he must blow up the Watergate Bridge again. What he faced was that Smith sent a whole tank battalion, more than 40 tanks and a large number of American soldiers to arch the Watergate Bridge.

Finally, on the night of February 6, 65438, the soldiers of Company 7 broke through the layers of American defense lines and blew up all the newly-built bridges and root bases of the enemy.

Polar bear corps:

In the First World War, the 3 1 regiment successfully invaded Siberia, Russia, and was awarded the title of "Polar Bear Corps" and personally awarded the "Polar Bear Flag".

At that time, the Seventh Division of the United States also allocated a battalion of 32 regiments, an artillery battalion of the division and a tank unit under the 3 1 regiment, so the 3 1 regiment was actually an armored reinforcement regiment at that time, with 3,300 people. The "polar bear regiment" was also the only regiment annihilated by volunteers in the Korean War.
