The Hebei – Rehe – Chahar Campaign was a series of battles fought in Northern China between the nationalists and the communists during the Chinese Civil War in the post World War II era, and resulted in communist victory. The nationalists lose over 24,390 troops in this campaign, including over 17,350 captured alive by the enemy and over 7,040 killed. Seven cities/towns and vast rural regions fell into the enemy hands, and additionally, the enemy had severed the communication/transportation lines of Beijing – Suiyuan Railway, Beijing – Chengde Railway, Beijing – Liaoning Railway, and Beijing – Hankou Railway. In contrast, the communists had successfully prevented the nationalists from sending nationalist force in northern China to Northeast China, in addition to the successes just described. The nationalist defeat was mainly due to the Chiang Kai-shek's uncompromising doctrine of holding on to as much land as possible, and as long as possible, which overstretched the numerically superior nationalist forces as they were dispersed to garrison vast regions. As a result, none of the garrison had enough strength to fight when enemy concentrated their forces and attacked with overwhelmingly numerically superior force.
