when did un troops approach the yalu river
Yalu River The Korean side of the river was heavily industrialized during the period of Japanese rule (1910–1945), and by 1945 almost 20% of Imperial Japan's total industrial output originated in Korea. During the Korean War, the movement of United Nations troops approaching the river precipitated massive Chinese intervention from around Dandong. In the course of the conflict every bridge across the river except one was destroyed. The one remaining bridge was the Sino–Korean Friendship Bridge connecting Sinuiju, North Korea to Dandong, China. During the war the valley surrounding the western end of the river also became the focal point of a series of dogfights for air superiority over North Korea, earning the nickname "MiG Alley" in reference to the MiG-15 fighters flown by the combined North Korean, Chinese and Soviet forces.[citation needed]
Triveni Sangam One such Triveni Sangam, in Allahabad, has the confluence of two rivers â€” the Ganges and the Yamuna (and the imaginary Saraswati River). The two rivers maintain their visible identity and can be identified by their different colours. The water of the Ganges is clear, while that of the Yamuna is greenish in colour.[1]
