 For the communists, it was impossible to achieve numerical superiority after sending in two divisions following the withdraw of four divisions, and the Independent 1st Division of the communist 7th Column withdrawn earlier was forced to be back in action again.The highest point in the Siping (city) was a water tower, and the nationalists turned it into a formidable bunker manned by tough veterans of the Chinese Expeditionary Force in Burma and India during World War II, and these sharpshooters armed with light machine guns had successfully beaten back attacks by an entire enemy regiment for four times.After concentrating over a dozen machine guns suppressing the nationalist fire from the loopholes of the bunker to cover sappers setting up the explosives, the enemy finally neutralized the bunker in its fifth attempt.
