What led to Joan of Arc being burnt at the stake?

Joan of Arc was 19 when she was burnt at the stake in Rouen by the English on 30 May, 1431. She died of smoke inhalation. The Cardinal of Winchester is recorded as having ordered her to be burnt a second time. Her organs still survived this fire, so a third burning was ordered to destroy the body completely. Her cinders and debris were to be thrown into the Seine.
