to the mountain tops. Furthermore, due to the lack of water, the water-cool machine guns could not function properly even after they were carried up to the mountain tops. The airdrop was completely insufficient to fulfill the daily need of the besieged force either. The critical minute Chiang Kai-shek ordered nearby nationalist forces to do their best to save the besieged 74th Reorganized Division, but the communists were aided by the internal fights among the nationalists. Li Tianxia, the commander of the nationalist 83rd Reorganized Division was a personal foe of Zhang Lingfu, the commander of the nationalist 74th Reorganized Division, and he was not willing to commit fully to save his foe. In addition, Li Tianxia was very worried that the communists were using the besieged nationalist division as a bait to annihilate his own force, since his own division was not as tough as the 74th Reorganized Division, which could withstand the communist onslaught and survive. If Li Tianxia's 83rd Reorganized Division were to be ambushed on the way in the open without any fortification on its way to save the besieged nationalist force, it would be certain that his weaker division would be completely destroyed. As a result, Li Tianxia only sent out a single regiment in a symbolic move, and just as he had expected, this regiment was completely destroyed by the waiting enemy. In contrast, the nationalist 25th Reorganized Division under the command of Huang Botao ventured out in full strength to carry out Chiang Kai-shek's order, and by May 14, they had reached the Yellow Cliff (Huang Ya, 黄崖) Mountain, which was a merely 6 km away from Menglianggu region, the last natural barrier. Both sides were keenly aware that whoever controlled the Yellow Cliff Mountain would decide the outcome of the campaign, and both sent out their crack troop to take the commanding peak of the mountain. The 16th Division of the communist 6th Column was tasked with capturing and securing the Yellow Cliff Mountain, and its 48th Regiment was the vanguard. After a forced march with troops had to eat and even sleep while on the march, the communist 48th Regiment finally reached the eastern foothill of Yellow Cliff Mountain. At the same time, a detachment of the nationalist 25th Reorganized Division also reached the western foothill of Yellow Cliff) Mountain. The 9th Company of the 3rd Battalion of the 48th Regiment
