    The 20 Jul 44 plot was the culmination of the efforts of several groups in the German Resistance to overthrow the Nazi-led German government. For his involvement in the movement he was shot shortly after the failed attempt.

    Describing her late husband, Nina von Stauffenberg said, "He let things come to him, and then he made up his mind ... one of his characteristics was that he really enjoyed playing the devil's advocate. Conservatives were convinced that he was a ferocious Nazi, and ferocious Nazis were convinced he was an unreconstructed conservative. He was neither."

    US officers plant flag eight minutes after troops begin landing on Guam

    Guam is the largest of the Marianas, 32 miles long and 10 miles wide. It had been a United States possession since its capture from Spain in 1898 until it was captured by Japan on 10 Dec 41, following the attack on Pearl Harbor. By 1944 it had a large Japanese garrison.

    The Japanese had learned from previous American assaults not to subject their men to the massive air and naval bombardments that would precede the invasion. Therefore their beach fortifications on Guam were sparsely manned, opting instead to heavily dig themselves in further inland.

    Although the 2nd Battle of Guam will be declared over in 21 days (10 Aug 44), some 7,500 Japanese soldiers will remain at large in the jungles and will continue fighting with unorganized guerrilla tactics for some time to come.
