Mukden: Climax of the Russo-Japanese War (1996)

(from the Introduction :)

Mukden is an operational level, two-player simulation of the climatic battle of the Russo-Japanese War of 1904-1905. Players control the divisions and brigades actually present on that distant battlefield in an attempt to out perform their historic counterparts. The tempo of play is dominated by Japanese offensive efforts to capture Mukden, threaten the Russians' overall logistical situation, or destroy a significant portion of the Russian army.
