WASHINGTON (Yonhap News) ― A U.S. lawmaker is pushing for legislation on the Battle of Chosin Reservoir, one of the fiercest fights in the Korean War, a congressional source said Sunday.

Rep. Don Young, a Republican from Alaska, submitted a bill earlier this month to designate a peak in the state as “Mount Chosin Few,” a move supported by Korean War veterans there who participated in the battle in December 1950, also known as the Changjin Lake Campaign, according to the source.

The Chosin Few is a group of former U.S. Marines who survived the 17-day fight in North Hamgyeong Province, now in North Korea, amid freezing weather.

The 1st Marine Division of the U.S. fought their way out of the Chosin Reservoir against seven Chinese divisions. It enabled many other U.N. troops in nearby areas to buy time for the successful withdrawal to the South.

While data varies, over 900 U.S. soldiers were killed and thousands others went missing. An estimated 35,000 Chinese troops were killed.

The Mount Chosin Few Act is to commemorate the U.S. victims and survivors, and raise public awareness on the historic event, Young said.

“The designation of an unnamed peak in the Chugach National Forest in the State of Alaska in honor of the soldiers who fought courageously in the Chosin Reservoir during the Korean War would be a fitting tribute to the sacrifices the Chosin Few made for their country,” he was quoted as saying in the bill.

The legislative effort comes ahead of the 62nd anniversary of the outbreak of the Korean War on June 25. The war ended with a cease-fire, leaving the peninsula still divided.
