Developed during WWII by Nazi Germany as a wepon to deliver carnage to enemy in far off England. This was the first of two of the so-called Vengence weapons. The V-1 was first launched against London on June 13, 1944, one week after (and prompted by) the successful Allied landings in France. At peak, more than one hundred V-1s a day were fired at southeast England, 9,521 in total, decreasing in number as sites were overrun until October 1944, when the last V-1 site in range of Britain was overrun by Allied forces. After this, the Germans directed V-1s at the port of Antwerp and at other targets in Belgium, launching a further 2,448 V-1s. The attacks stopped only a month before the war in Europe ended, when the last launch site in the Low Countries was overrun on March 29, 1945.
