泸定桥
On the eastern bank, the right column already started their march to the Luding Bridge. The Nationalist 10th regiment, 4th brigade was the closest opposing force to the communists, and began spreading out along the Dadu river. On May 27, 1935, the 2nd regiment of the 1st division of the communist force defeated the nationalist 10th regiment at the Waba (瓦坝) after several hours of fierce fighting. The next day, after more than a 50 km march, the communist 2nd regiment successfully crushed the remaining units of the nationalist 10th regiment. On May 29, 1935, the communist 2nd regiment engaged the nationalist 11th regiment, and with the help of the communist 3rd regiment, which arrived after the battle began, completely wiped out the nationalist 12th regiment. The communist 2nd and 3rd regiments then proceeded to destroy the brigade headquarters located 25 km away from Luding Bridge. The nationalist commander of the 4th brigade, Yuan Guorui (袁国瑞), fled with his surviving staff to the surrounding mountains, from where they were unable to reestablish links with the rest of the nationalist forces after the bridge and the city were both taken by the communists. This left to Li Quanshan (李全山), the regimental commander of the 38th regiment, the task of organizing the defense, which he was unable to accomplish.
