Battle of Jiulianshan


The Battle of Jiulianshan was an unsuccessful counter-guerrilla operation launched by the Nationalists against the Communists during the Chinese Civil War after World War II, in the border region of Guangdong, Jiangxi and Hunan.
Jiulianshan, was a Communist guerrilla base in the border region of Guangdong, Jiangxi and Hunan. In November 1948, the Nationalist forces from Guangdong including 13th Security Regiment, the 5th Regiment, and a battalion of the 1st Security Regiment, were dispatched to eradicate the local Communist guerrilla. The Nationalists enjoyed both the technical and numerical superiority, so they decided to attack on multiple fronts in separate directions. In contrast, the Communist guerrilla decided to concentrate their forces to achieve numerical superiority on one front against the attacking Nationalists, and then fight the enemy at the next front using the same tactic to overcome their own disadvantage.

Ambush at the Dongjiang River

As the nationalists sent their supplies via Dongjiang River upstream from Heyuan on November 15, 1948, the enemy set up an ambush in the section from Yellow Field region to White Horse region. The entire nationalist convoy was lost with over 70 troops killed and over a dozen boats full of supplies having fallen into enemy hands.
On November 20, 1948, a group of communist guerrillas staged a feigned attack on Great Lake region, and as the nationalist 1st Security Regiment sent out a company to engage the enemy, the enemy immediately retreated, lured the unsuspecting nationalists into the preset ambush in the Lion's Brain mountains, where the communist guerrilla 3rd Regiment was waiting, and the entire nationalist company was wiped out.

Resupply Effort and Second Ambush

Due to the previous loss of supplies in November of the previous year, the nationalists were forced to re-supply. On January 8, 1949, 5 infantry companies and one artillery company of the nationalist 13th Security Regiment totaling 600 troops organized another convoy consisting of three supply boats that went upstream again on the Dongjiang River. The Communist guerillas concentrated their 3rd Regiment, 5th Regiment, 7th Regiment, and Independent 5th Group totaling 1,000 troops, to ambush the convoy while the Nationalists were stopped at the riverbank. On January 11, 1949, after a fierce nine-hour-long battle that lasted from noon till 9:00 PM, the Nationalists managed to successfully break out, but all of the suppliers had lost to the enemy, in addition to suffering over 190 fatalities. After this setback, the Nationalists canceled any further plans to eradicate the Communist guerrillas and withdrew all their deployed forces.

Reasons for Nationalist Failure

The Nationalist failure was mainly due to their grave underestimation of the enemy's strength and determination. Although the so-called Communist guerrilla regiments were actually only battalion-sized, they still formed a sizable and formidable force when concentrated. In contrast, although the Nationalist enjoyed both the technical and numerical superiority, they did not have advantage when their forces were deployed separately in smaller numbers.
