 Welcome to All Hands Update. This is your week in Navy history. On December 11, 1941, just four days after the Japanese attack on Pearl Harbor, President Franklin D. Roosevelt officially signed the declaration of war on Germany and Italy, which brings the U.S. into the European conflict. Just hours before the declaration was signed, Germany declared war on the U.S. On December 12, 1972, Apollo 17 commander, Navy Captain Eugene A. Cernan, walked and raised the U.S. flag on the moon. Apollo 17's command module pilot was Navy Commander Ronald E. Evans, and Harrison H. Schmidt was the lunar module pilot. December 13, 1943, German submarine U-172 was sunk west of the Canary Islands. Despite being damaged by the submarine, USS Osmond Ingram, USS Georgie Badger, and USS Clemson were able to still sink U-172 with help from aircraft attached to USS Bogue.
