Why is Joan of Arc still remembered? All that Joan was able to accomplish at such a young age is unparalleled in history. Only 17 when she was put in command of the French army, she is the youngest person to ever command the armies of a nation. In only a couple of months she was able to completely reverse a war that had been going on for almost 100 years that the French were about to lose. The victories she won at Orleans and Patay are considered among the greatest in all of history. Add to all of this her prophetic ability that was always correct, her personal devotion to God and commitment to purity and it is a story that can only be described as incredible.
