 Welcome to All Hands Update. This is your week in Navy history. November 9, 1921, USS Olympia arrived at the Washington Navy Yard with the body of the unknown soldier of World War I. On November 11, President Warren G. Harding officiated the Intermittent Ceremony at Arlington National Cemetery. On November 12, 1912, Lieutenant Theodore Ellison made the first successful launch of an airplane by a catapult at Washington Navy Yard. The successful launch led to a flying boat being launched from the same catapult a month later. On November 12, 1942, the naval battle of Guadalcanal began with a Japanese air attack on U.S. ships. Over the next four days, the Japanese would lose two battleships, a heavy cruiser, three destroyers and many valuable transports, allowing the U.S. to shift to the offensive.
