Yalu: The Chinese Counteroffensive in Korea, November 1950 to May 1951

Released in 1977 by Game Designers' Workshop, Yalu: The Chinese Counteroffensive in Korea was part of the publisher's commitment to simulating pivotal 20th-century military conflicts. Developed during a period when the wargaming community was deeply invested in the tactical specifics of the Korean War, the game was designed to explore the complex logistics and the rapid tactical shifts that occurred following the entry of the People's Volunteer Army into the Korean theater late in 1950.

The game design followed the rigorous, hex-and-counter tradition established by GDW during the mid-1970s, emphasizing the impact of terrain and supply lines on movement. While GDW eventually became more widely recognized for its science fiction titles like Traveller, Yalu remains a quintessential example of their historical library. It was received by the hobbyist community as a challenging, if somewhat dense, simulation that required players to manage the precarious balance between rapid maneuvering and the vulnerability of overextended supply corridors.
