  To the office and at 9:30 in the President’s office for the briefing on the Korean situation by General [J. Lawton] Collins, army chief of staff.

Collins gave some data on the amphibious landings made by Marines and infantry . . . yesterday. He said some 17,000 troops have been landed on the west coast in the vicinity of Inchon, near Seoul, far behind the present lines of the battlefront. Also tanks and mortars have been landed. . . . He said General [Douglas] MacArthur had reported it might take a month, because of rugged terrain, before these forces can connect with the forces in the south.

If the amphibious operations now in progress in Korea are successful, it is likely that in the very near future there will be either (1) Soviet or Chinese Communist direct intervention or (2) a suit for peace or an armistice by the North Koreans. NSC 81/1 clearly sets forth the action to be taken in the event of Chinese Communist or Soviet intervention. However, it does not as clearly set forth the immediate action to be taken in the event the North Koreans sue for peace or armistice. It is, therefore, considered a matter of urgency that a decision be made as to the immediate reply to be made by the Commanding General of the Unified [United Nations] Command [Douglas MacArthur] to any suit for peace or offer of cease fire which may be received prior to the conclusion of the discussions provided for in paragraph 23 of NSC 81/1.

  In the last 36 hours [at Inchon], I have witnessed a miracle, no less; all calculated to the end we discussed in Washington and as a first objective, i.e., that no American troops shall be required to fight in the cold, the mud, and the filth of a Korean winter.

General [Douglas] MacArthur has accomplished again that which many considered impossible. I need not tell you of the doubts in many minds concerning the success of this mission. It has been a most brilliant victory so far and I have no doubts as to the future. You know the situation up to the minute and I can add nothing to that. I am keeping accurate and complete notes plus photographs and will prepare a report when I return to Tokyo. It appeals to me that my mission is calculated to future record.

I go ashore tomorrow at noon and shall continue some time with the 1st Marine Division.

I guess you'd call it an end run, to use a football term. Inchon lies on the west coast of Korea, very close to Seoul and the 38th parallel which divides North Korea and South Korea. By making this landing in great force, the American forces got in behind the Communist North Koreans, who were further down this long and relatively narrow peninsula that makes up Korea. This meant that they had to back up and get out or they would be surrounded and annihilated. Pressure, of course, was being put upon them at the same time, by American forces further down the peninsula. The net result of the Inchon landing was that the North Korean Communist forces were pushed back to the 38th parallel. Things were going so well that it appeared back in Washington that the conflict was won. [General Douglas] MacArthur again was a great hero.

It [the Inchon landing] was a brilliant concept and magnificently executed, attended with a great deal of luck, which is essential to any successful campaign.

At our staff meeting at 11 o’clock [Press Secretary to the President] Charlie Ross said he had a telephone call from Senator [Millard] Tydings of Maryland, who is a candidate in the Maryland primaries today, suggesting that General [Douglas] MacArthur send a message from Tokyo on the appointment of General [George C.] Marshall as secretary of defense [replacing the recently resigned Louis Johnson]. The President commented that MacArthur would never do that.

Marshall] had a head on him, my goodness alive, and was the kindliest man you ever met but he could be mean as Hell to Major Generals. . . . Marshall was not only a great military leader, he was a great Secretary of State, he was a great Secretary of Defense, and the reason for that was he could analyze a fella by sittin’ and talkin’ to him. And I’ve heard him analyze certain commanders and he gave me the best analysis of [General Douglas] MacArthur that’s ever been had. He did it voluntarily. I didn’t ask him for it.

    Although an opponent of the Inchon operation, Smith headed the Marine assault force. Following a mammoth bombardment by Navy ships and aircraft, on the morning of September 15 the 3rd Battalion of the 5th Marines seized Wolmi-do, an island connected by causeway to the city of Inchon. The operation waited until Inchon's drastic tides were again favorable and at 3:30 in the afternoon the remainder of the 5th Marines landed on Red Beach, north of the causeway near the heart of Inchon. Shortly thereafter, the 1st Marines landed on Blue Beach, just south of the city. With the U.S. Marines encircling the city, South Korean Marines addressed the last of Inchon's 2,000 defenders the following morning. The 1st Marines advanced east down the highway to the Seoul suburb of Yongdungpo, while the 5th took a more northerly route to Kimpo airport and the Han River beyond. Kimpo airport was recaptured by September 18 and that afternoon Corsairs of the First Marine Aircraft Wing landed and began operations.
