Bombing of Treviso in World War II Bombing of Treviso in World War II The bombing of Treviso took place on 7 April 1944, during World War II. 159 Boeing B-17 Flying Fortress of the United States Army Air Force (escorted by Lockeed P-38 Lightning fighters) dropped over 2,000 bombs during an attack which lasted five minutes (from 1.24 PM to 1.29 PM); the target was the local marshalling yard, but the inaccuracy of the bombing caused most of the bombs to fall all over the city, destroying most of it. Out of 4,600 buildings, 700 were destroyed, 1,100 heavily damaged and 1,962 slightly damaged. A large
American Theater (World War II) other heavy bomber projects were cancelled. During the final months of World War II, Japan had planned to use plague as a biological weapon against U.S. civilians in San Diego, California, during Operation Cherry Blossoms at Night. The plan was set to launch at night on September 22, 1945. However it was shelved after Yoshijiro Umezu, Chief of the Imperial Japanese Army General Staff, rejected it. Additionally Japan surrendered five weeks before the plan had been intended to take place. These false alarms have generally been attributed to military and civilian inexperience with war and poor radars of the era.
