From Peng Dehuai's Autobiography he mentions on the 19th of October 1950 during the first campaign of the Korean War he reached the power station at "Raekosao," does anyone know what city he is referring to? Im unable to find anything by the name "Raeksoao" so if anyone has a better understanding of korean geography or language do you happen to know where this (city?) is or what a more accurate pinyin romanization would be to find out more about this location?
Based on context I assume we can place it between the Yalu river and Unsan
