Uijeongbu Corridor
의정부 회랑
A geographic corridor running north-south through the city of Uijeongbu, just north of Seoul, formed by the natural defile between Dobongsan and Suraksan mountains within the Chugaryeong Rift Valley. This corridor has served as the primary invasion route from the north into Seoul since ancient times. On 25 June 1950, the Korean People's Army concentrated its 3rd and 4th Infantry Divisions and the 105th Tank Brigade along this axis, where the open valley terrain allowed T-34 tanks to maximize mobility and shock effect, breaking through the ROK 7th Division's defenses on the first day and opening the decisive path to the capture of Seoul.
