In the early 15th century, a French village girl became a heroine for her role in the French victory during the Lancastrian phase of the 100 Years War. But it took 600 years before Joan of Arc was canonised as a Roman Catholic Saint. How did she become such a famous name in history? Why did she join the Siege of Orléans? And how did she come to be burned at the stake at just 19 years of age? Rob Weinberg asks the big questions about this legendary figure to medieval historian Major Imogen Corrigan.
