Havoc! One of the few known medieval battlefield orders is the cry of ‘Havoc!’. Havoc released the army from any formation and gave freedom to loot, and was an order only ever to be given when it was utterly certain that a battle was won and discipline was no longer required. It was considered so dangerous that it was expressly forbidden without permission from the army’s commander. A wrongly timed cry of havoc could cost a battle and there were severe punishments for crying havoc without permission – sometimes extending to beheading.
