Night of the Violet Ray
As the Red and White armies battled over Kiev during the Russian Civil War, both sides won the city several times. Citizens were getting tired of the current rulers fleeing and leaving them to the mercy of the other side. The Red Army was once again poised to take over. The Whites announced that the Reds had a new secret weapon: the Violet Ray. It would kill anyone outside (while not damaging property) and the Reds were going to use it at midnight! As the population hid from the ray, the White leaders snuck out of town.
