[O]rders were usually sent in the form of a telegram to General [Douglas] MacArthur, which was drafted and worked over by the Defense Department, the State Department . . . . And then it was passed on by the President and it was brought back to the Pentagon and sent to General MacArthur.

. . . Mr [Dean] Acheson [the Secretary of State] was in New York at the UN [United Nations] and I was with him, we were staying at the Waldorf hotel. Dean Rusk who was then Assistant Secretary of State for the Far East brought out the instructions [of September 27, 1950] that were to go to MacArthur . . . , they had not gone to the President but they had been cleared by the joint Chiefs of Staff. It is one of the few arguments I ever had with Dean Acheson which really got bitter.

I read the instructions to [the commander in the Far East] General [Douglas] MacArthur, they in fact said it was left to him what he did, removed the 38th parallel as a barrier said that he was to deal with this in military terms and left it in my judgment, much too much to his own discretion in the crossing of the parallel [into North Korea] and will he stop thereafter. And I said this to the Secretary. And I said I think this is too vague it is too general. And he got furious with me, and he turned to me and said, look, how old are you. And I said that I am 30 years old, and said are you going to take on the entire Joint Chiefs of Staff of the United States. I said this instruction is wrong.

I don’t know what Mr. Truman’s position was at that moment. I was not present in a discussion of those orders with him, because we were in New York we stayed in New York, and right after my objection and Dean Rusk was standing there and everyone thought I was ridiculous maybe--in terms of the propriety by role it would probably be right. And from there he took the instructions back and they went out. . . .

Before the period which I'm now going to speak about, which is the 28th of September . . . [i]t was clearly decided by the military and by everybody that as a tactical situation, the 38th Parallel should not be allowed to interfere with the operations of the army pending further understandings and discussions. In other words, if a division or a regiment or whatever it is had to move, it moved wherever it had to move in order to carry out a battle effectively. If that meant crossing the 38th Parallel, cross it. Don't walk up to some surveyor's line and stop shooting at that point.

When the authority was given to General [Douglas] MacArthur to cross the 38th Parallel [into North Korea], there were certain limitations placed on him. One specific limitation was that he should avoid approaching too close to the Yalu [River, forming the border with China]; another was that no non-ROK troops - that is, no American troops and none of the other United Nations troops other than the ROK [the South Korean troops] - were to go all the way up to the Yalu.

. . . [At the September 28 press conference, the President was asked if the] government had given General MacArthur "specific authority" to cross the 38th parallel in Korea and he replied that he could not answer that now. In answer to another question he said that MacArthur was under strict orders of the President and the Chief of Staff and he would follow those orders.

(Previously the President had indicated to us that MacArthur had been given orders not to cross the parallel without further orders.)

A questioner pointed out that a week or so ago the President had said the matter of crossing the 38th parallel was a United Nations decision. The President said that was correct and the reporter then said the President had just said MacArthur was under his direct orders. The President replied that was correct but the United Nations would have to act on it first.

Then some confusion over questions arose that later caused us considerable trouble.

A reporter said that Americans in the United Nations had given out a six-point program for settlement of the Korean situation and the President asked, in reply, "You mean the broadcast asking them to surrender?"

The correspondent said no, what he was thinking of was a plan for the settlement of the Korean situation based on our point of view.

The President replied it had not been taken up with him and that "the broadcast of General MacArthur - I think made today - was taken up with me, inviting them to surrender. I think he is making that broadcast today. You will have to consider that off the record, however, until General MacArthur makes the broadcast."

He was asked if that was a demand for unconditional surrender and the President replied "you will have to wait for General MacArthur's broadcast, and then I will comment on that and answer your question."

Later in the conference he was again asked about the broadcast and it being off the record and he repeated that it was until MacArthur makes it.

Sometime afterward, during the late afternoon, newspapermen came in to see me and then to see [Press Secretary] Charlie Ross and raised a considerable rumpus. Apparently they wanted it put on the record but it was not clear just what they were after. We learned, however, that the President was mistaken in thinking the broadcast was to be today. Instead we were informed it would be made on October 1st [September 30 in Korea].

On the 28th of September, I got a message from the President asking me to come back to Washington. I came back and got there the night of the 28th. On the morning of the 29th I went to a Cabinet meeting, and after the Cabinet meeting, the President [Secretary of Defense] General [George C.] Marshall and I went to the Blair house -- I think there was an NSC [National Security Council] meeting after the meeting, but after that we went to the Blair House where we had lunch together. After lunch General Marshall produced a large map of Korea . . . . on which were the troop disposition, and gave a report of the situation. He reported that the North Korean army was dissolved -- it was in complete rout -- and the question was, what should [General of the Army Douglas] MacArthur be directed to do . . . . And he now laid this before the President for discussion by us. As I recall it, . . . this map showed a line slanting from southwest to northeast across Korea -- and it was proposed that MacArthur be told to advance his troops, his whole 8th Army, to this line and hold it at the line. . . .

And he was . . . told that operations north of that line must be conducted by Korean troops and what the Korean troops could accomplish they could accomplish, and what they couldn't accomplish wouldn't be accomplished -- that the 8th Army as such -- or the 10th Corps, that had then been separated -- would be held at that point. This, I think, was originally sent out in some form or other on the 27th. It was discussed by the President and General Marshall and with me. All the various considerations which later became important were mentioned; the difficulty of operations north of that line as your own communications were extended, as your troops got more and more into an area of trouble on the other side, and your own air forces became attenuated; the danger of misconstruction on the Chinese part, and the fact that this had been a very tender and delicate part of Korea for almost all the years that the Japanese were in occupation -- there was always [guerilla] trouble up in this area. . . .

I agreed that this was the right thing to do. And a directive was sent off, I think dated September 30th by the Joint Chiefs of Staff to MacArthur, giving him this instruction. I went off then for some time - back to New York and various places - and regarded this matter -- as far as I knew, this was settled. This was where the army was and whatever happened north of that would be a feeling out operation . . . . MacArthur made his demand for surrender on the 30th of September.

The actual crossing of the thirty-eighth parallel was specifically authorized by the Secretary of Defense [George Marshall], to me, in a message, a personal message [dated September 29, 1950], which said that he did not - that the Defense Department did not wish to in any way embarrass me tactically or strategically in my crossing of the thirty-eighth parallel.

The halt that took place after the Inchon landing, which was something magnificently spearheaded by the Marines - the halt in crossing the parallel was due entirely to logistical difficulties. It was with the greatest difficulty that troops could be supplied.

Congressional testimony, May 3, 1951

         

Secretary of State Dean Acheson Image: Secretary of State Dean Acheson. Source: Truman Library.   The discussions about us crossing the 38th Parallel occurred in the U.N. . . . . I went up to New York and was there during these discussions. You will see from the resolution that we put before the General Assembly, introduced I think in late September and discussed in October, that the resolution contemplates the crossing of the 38th Parallel. It contemplates, really, the reduction of all forces in North Korea, the reestablishment of order, the creation of a unified, democratic, and all the other good adjectives, [government] in Korea, and is a very optimistic resolution. This was discussed and passed at the U.N. after Inchon
had occurred, and when the North Korean forces were simply disintegrating. And it appeared as though everything were going smoothly. You will see from [Ambassador] Austin's speech . . . that it was almost a naive view of what was likely to happen. We were going to establish a free, independent and united country; we were going to have a strong U.N. Commission; we were going to have free elections; we were going to reconstruct and develop Korea; we were going to retain forces only so long as it was necessary to achieve these objectives; all special privileges of any nation were going to be done away with, and it was going to be an independent foreign country. That was a rather bland view of the situation.

[Press Secretary to the President Charles] Ross was not in today. I came in and went to General [Omar] Bradley's briefing session on Korea. . . . The North Korean forces seem to be shattered and trying to escape to the north.

United Nations forces have practically reached the 38th parallel in some sections and Bradley referred to newspaper reports that they were holding up there. He said he did not know the basis of those and indicated that orders had been given permitting [U.N. Commander General Douglas] MacArthur to continue the drive over the parallel and into north Korea. The President indicated this was so.

Bradley reported that since outbreak - in the past 95 days - the air force has flown over 40,000 missions.

[Naval Aide to the President] Admiral [William] Dennison asked the General if all our forces were a part now of the 8th Army. Bradley said that the 10th Corps at Seoul, which made the landings, have not yet been made part of the 8th Army but are directly under General MacArthur. He said they probably would be made part of the 8th as soon as the two forces, those coming up from the South and those Seoul join up completely. . . .

The President left about 12:30 for the [Presidential yacht U.S.S.] WILLIAMSBURG to have lunch aboard with Admiral Dennison. Others who are to leave on the cruise were to go aboard during the afternoon. . . . Charlie Ross and [The Special Assistant to the President] John Steelman will fly down Tuesday morning from Anacostia to the Patuxent base and join the ship and [Special Counsel to the President] Charlie Murphy and [Administrative Assistant to the President] George Elsey will join it Wednesday.
