On October 25, 1950, with General Douglas MacArthur's United Nations forces closing in on what would have otherwise been a quick victorious end to the Korean War, Communist Chinese forces began pouring across the border. In northeastern Korea, the US X Corps, led by Major General Ned Almond, was strung out with its units unable to support each other. Those units near the Chosin (Changjin) Reservoir included the 1st Marine Division and elements of the 7th Infantry Division. You lose the game if you are unable to achieve the third Order Objective, or if one or more of your Units is completely destroyed; you win the game if you are able to successfully complete all the Order Objectives.
