For members of the U.S. Army's "Task Force Faith" and the First Marine Division, the Battle of Chosin Reservoir is an epic story of survival, courage, and ingenuity. Their exploits are well known--woven into the storied histories of the U.S. Army and Marine Corps. Now, for the first time, Attack at Chosin recounts this battle from the Chinese perspective, describing the advance that forced General MacArthur to reorient his strategy, which not only marked a turning point in the Korean War but impacted events in Asia in ways that still resonate today. The Battle of Chosin Reservoir, as the Chinese commanders foretold, determined the fate and length of the Korean War. Author Xiaobing Li describes the fighting that began on November 27, 1950, when 150,000 soldiers from the Chinese Ninth Army Group attacked the First Marines and elements of the 7th Infantry Division in the remote mountains of North Korea. It was a calculated attempt to repel MacArthur's "home-by-Christmas" offensive and to deter UN forces from further advances toward the Chinese border. The fierce fighting that followed, combined with the bitter cold, made Chosin one of the deadliest battles of the war. By December 17, after suffering more than 40,000 casualties and failing to achieve their campaign objectives to destroy the American divisions, the Ninth Army Group was forced to withdraw. One day later, on December 18, 1950, the remaining survivors were recalled to China. As the first book to explore the role of command and control, technology, and combat effectiveness from the point of view of the Chinese, and to examine cooperation and friction between Beijing and Pyongyang, Attack at Chosin sheds new light on the ultimate military success of the UN forces during the Korean conflict. Li also provides invaluable insights into Chinese military doctrine, strategy, and tactics that continue to influence foreign policy and American military institutions today.
