This wargame is the second in the Oriental Flagship Company's "Red Memories" series. (The Nanchang Rebellion is the first in the series.) The game is a simulation of a famous campaign in the Chinese Civil War. The player controlling the Communist units deploys and moves secretly on a small magnetic board, while the Kuomintang player's units are visible, though face down, on the main board.
The game's Chinese name is 四渡赤水。
