South Korea can be divided into four general regions: an eastern region of high mountain ranges and narrow coastal plains; a western region of broad coastal plains, river basins, and rolling hills; a southwestern region of mountains and valleys; and a southeastern region dominated by the broad basin of the Nakdong River.

The United States participation was critical for preventing the near defeat of the Republic of Korea by northern forces, as well as fighting back for the territory gains that define the South Korean nation today.

UN troops established a defensive perimeter around the city known as the Pusan Perimeter in the summer and autumn of 1950.

After the first two months of war, South Korean Army (ROKA) and American forces hastily dispatched to Korea were on the point of defeat, retreating to a small area behind a defensive line known as the Pusan Perimeter.

This 140 mi perimeter enclosed about 10% of Korea, in a line partially defined by the Nakdong River.

Daegu is located in south-eastern Korea about 80 km from the seacoast, near the Geumho River and its mainstream, Nakdong River in Gyeongsang-do.

Daegu sat inside the Pusan Perimeter, however, so it remained in South Korean hands throughout the war.
