From newspapers of Sept. 13, 1945: Field Marshal Gen. Sugiyama, commander of Japan's 1st Imperial Army and a former war minister, kills himself before he can be arrested by U.S. troops. Sugiyama's wife dies with him. Adm. Shigetaro Shimada, one of the planners of the attack on Pearl Harbor, gives himself up quietly. "I don't suicide," he tells his captors. Gen. Douglas MacArthur orders the disbanding of the Black Dragon Society, which for 40 years has been an instrument of Japanese imperialism. Adm. Lord Louis Mountbatten accepts formal surrender of Japan's southern armies in Singapore. Field Marshal Count Juichi Terauchi, Japan's southern commander, misses the ceremony as he is ill. Mountbatten says he will insist on receiving Terauchi's personal surrender. "His sword is the one thing I want out of this war," Mountbatten says. In Washington, some Republican members of Congress complain that Britain's new Labor government might use any postwar aid to help pay for its socialist program. "I think that is a perfectly silly conclusion," responds President Truman. The British have every right to any kind of government they wish, Truman says, and it is none of our business as long as friendly relations are maintained.
