泸定桥
The Communist forces were harassed by both the Kuomintang and local warlords. To avoid a fatal confrontation, Zhou and Mao maneuvered the Red army south and west, through Guizhou, Sichuan, and Yunnan, feigning attacks on Guiyang and Kunming to disguise their movements. The First Red Army crossed the Yangtze (the section of Jinsha River) on May 9, 1935, finally escaping determined pursuit, but still had to deal with dangerous mountain passes at heights of up to 4,000 meters, rough climatic conditions, shortages of food, clothing, and equipment, and tribes of local ethnic groups hostile to Chinese encroachment. The Red Army had to capture river crossings defended by warlords and Nationalist troops. The most famous was Luding Bridge, extolled in official history as an heroic triumph, although many historians now believe that the difficulty of the battle was exaggerated or that the incident was fabricated for propaganda purposes.
