The UN forces established a perimeter around the port city of PusanBusan throughout July and August 1950. Roughly {{convert|140|mi}} long, the perimeter stretched from the [[Korea Strait]] to the [[Sea of Japan]] west and north of Busan.{{sfn|Stewart|2005|p=225}} To the west the perimeter was roughly outlined by the Naktong River where it curved at the city of Taegu, except for the southernmost {{convert|15|mi}} where the Naktong turned eastward after its confluence with the [[Nam River (Korea)|Nam River]].{{sfn|Appleman|1998|p=252}} The northern boundary was an irregular line that ran through the mountains from above [[Waegwan]] and [[Andong]] to [[Yeongdeok-eup|Yongdok]].{{sfn|Stewart|2005|p=225}}

With the exception of the Naktong [[River delta|delta]] to the south, and the valley between Taegu and [[P'ohang-dong]], the terrain is extremely rough and mountainous. Northeast of P'ohang-dong along the South Korean line the terrain was especially treacherous, and movement in the region was extremely difficult. Thus, the UN established the Pusan Perimeter in a location outlined by the Sea of Japan to the south and east, the Naktong River to the west, and extremely mountainous terrain to the north, using the terrain as a natural defense.{{sfn|Appleman|1998|p=253}} However the rough terrain also made communication difficult, particularly for the ROK forces in the P'ohang-dong area.{{sfn|Appleman|1998|p=255}}
