Origin of the flag of Scotland is shrouded in mysteries and legends. Conventional wisdom associates it with the battle in the IX century to the east of the modern Edinburgh. In 832 AD, the army led by the Picts Angus Mack Ferguson, together with an army of Scots, was surrounded by a much larger army of England. Before the battle, Angus prayed to God for victory despite conceding in the amount of the army. During the battle, the clouds parted, forming a white diagonal cross, the very cross on which St. Andrew was crucified.
