The Pusan Perimeter

Improved Essays
The Korean War officially started in 1950 and ended in an armistice in 1953 with the Demilitarized zone falling at its pre-war position on the 38th parallel. The Democratic People’s Republic of Korea (North Korea), with support from its Communist neighbors of China and the Soviet Union, invaded south past the 38th parallel in June of 1950 attacking the Republic of Korea (South Korea). North Korea’s invasion resulted in initial success until the United Nations intervened in the defense of South Korea with the introduction of military forces. With this introduction of additional military forces, the North Korean advance came to a halt and the fate of the Korean peninsula rested on the defense of the Pusan Perimeter by the South Korea and its …show more content…
The defense of the Pusan Perimeter was now a collective operation under the United Nations. The UN was able to establish a defensive line using the natural barrier of the Natong River that ran an estimated one-hundred miles north to south on the western border and fifty miles west to east on the northern border. The Pusan Perimeter created time for the UN forces to utilize the deep sea port of Pusan to its advantage. As long as UN forces were able to pour in fighting forces and supplies into South Korea, the stronger the perimeter would be and preparations for a counter attack could …show more content…
In addition to the rail system, the UN also possessed the very valuable deep sea port of Pusan, which allowed for mass tonnage of supplies to be shipped in and railed to the frontlines. UN forces understood that a collapse in the Pusan Perimeter would mean certain defeat, in turn the Korean Peninsula falling into communist control and potentially being used as a stepping stone for further communist expansion. UN forces deployed three American divisions along with one South Korean division on the Western front. The northern front was held three additional South Korean divisions. This defense left the divisions desperately thinned out resulting in the front line only being defended by strong points leaving holes in the front line. An order was given to UN troops by the Commanding officer, General Walton H. Walker, to hold the line at all cost, which is better known as the “Stand or Die” order.
General Walker’s order was for good reason because the perimeter was facing a heavily equipped and battled harden North Korean force. The North Koreans positioned six Infantry Divisions on the western flank and an additional four against the northern flank. An armored tank unit was held in reserve to exploit any possible breaches through the UN defensive line. In addition to the ten divisions, North Korea would also move three more divisions

    Following the liberation of Seoul, South Korea in 1950, Americans were ecstatic about General Macarthur’s long fought and outstanding victory. American and South Korean forces continued to push well beyond the 38th Parallel—the delineation between North and South Korea—towards the Yalu River, the border between North Korea and Chinese Manchuria. In spite of the increasing likelihood of Chinese intervention, American and UN intelligence specialists ignored the possibility. Little did they know, that not only was it feasible, it was imminent. The Marines at the Chosin Reservoir prevailed despite being vastly outnumbered and outmaneuvered while underestimating their capabilities to relinquish security to Chinese and Korean forces by seizing an offensive initiative.…

    At the end of World War II and finally liberated from nearly four decades of brutal occupation after Japanese defeat in 1945, the Korean peninsula found itself torn between two foreign ideologies.

The Chinese intervention pushed the United Nations (UN) back to the 38th parallel where both sides dug in strong and sturdy defensive positions.

    The Korean division started the day the 38th parallel was settled on during the Potsdam Conference nearing the end of the Second World War. The 38th parallel was to serve as the dividing line of Korea, which was going to be occupied by the Soviet troops in the north and American troops in the south.

    The answer to the question, “Who started the Cold War?”, has been the subject of debate for 70 years. Unlike a situation where the first bomb is dropped or weapon fired, the start of the Cold War was more subtle and shrouded with a cloak of opposing ideologies. Ultimately, the Cold War sprung up as a result of the controversy between communism and capitalism. The differences are most pronounced with respect to the economic systems. In communist controlled countries, private ownership of property and business is forbidden and the 'society ' or government owns everything.…
