"The General Order No. 1, drafted on August 11 (1945) by the United States for Japanese surrender terms in Korea, provided for Japanese forces north of latitude 38° N (the
38th parallel) to
surrender to the Soviets and those south of that line to the Americans.
"Stalin did not object to the contents of the order, and on September 8 American troops landed in southern Korea, almost a month after the first Soviet entry.
"On the following day the United States received the Japanese surrender in Seoul. There were now two zones—northern and southern—for the Soviets had already begun to seal off the 38th parallel."
