The Campaign to Defend Siping (四平保卫战) was a struggle between the Nationalists and the communists for the control of Siping during the Chinese Civil War in the post World War II era. This campaign was characterized by the fact that the supreme commanders of both sides had overestimated their strength and set unrealistic goals, but in both cases, the brilliant frontline commanders on both sides had successfully averted the potential catastrophes by convincing their respective supreme commanders to change their original decisions.
