Joan of Arc is beatified by Pope Pius X in a ceremony held in St. Peter's Cathedral. Nicknamed "The Maid of Orleans," Joan of Arc claimed that God sent her visions with instructions on how to help the French army beat back the English invaders.
Some of the French leaders accepted her claims, though their situation as so bad that they didn't have anything better to place their hopes in. Joan made major changes to the French army's tactics, moving them from passive and defensive to more offensive actions. Under her leadership the French won a number of quick and important victories.
