Hörbuch: U. S. Marine Operations in Korea 1950–1953 - Volume I The Pusan Perimeter

It meant little to most Americans on 25 June 1950 to read in their Sunday newspapers that civil strife had broken out in Korea. They could hardly have suspected that this remote Asiatic peninsula was to become the scene of the fourth most costly military effort of American history, both in blood and money, before the end of the year. With a reputation built largely on amphibious warfare, Marines of the 1st Brigade were called upon to prove their versatility in sustained ground action. On three separate occasions within the embattled Perimeter—south toward Sachon and twice along the Naktong River—these Marine units hurled the weight of their assault force at the enemy. ...and at no point did Marines give ground except as ordered. The quality of their performance in the difficult days of the Pusan Perimeter fighting made them a valuable member of the United Nations team and earned new laurels for their Corps. - Summary by Montross and Canzana and Lemuel Shepherd
