Firebombing is a bombing technique designed to create a firestorm in the target city. This technique makes use of incendiary bombs to start a massive fire, and can also include a preliminary bombing run designed to prepare the city for burning. This bombing technique was as effective as the atomic bombs used against Japanese cities at the end of WWII.
