From newspapers of Sept. 3, 1945: Thousands of American occupation troops are pouring into Yokohama. In the past four days, 25,000 have arrived by air and sea. It is unknown when Gen. Douglas MacArthur will move his men into Tokyo. He clearly is reluctant to spread his troops out too thin. "What we got in the first three days was only a guard for Gen. MacArthur," says Col. A. E. Schanze of the 8th Army. "We stuck our head in without support from the rear." Lt. Gen. Tomoyuki Yamashita, Japan's most famous military leader, surrenders his remaining forces in the Luzon mountains of the Philippines. Yamashita, the conqueror of Malaya and Singapore, had refused to yield until he had proof that Japan's leaders had capitulated. More than 100,000 Japanese soldiers surrender on Truk, the Palau group of islands, and Pagan and Rota in the Marianas. The Army and Navy order their censors to stop reading the mail of American armed forces abroad. The order is a consequence of Japan's official surrender a day ago. In Washington, the War Department says it has reduced the discharged score for enlisted men from 85 to 80 points and that enlisted men 35 and over with at least two years of service will be released upon application.
