Joan of Arc

Henry V was perpetually in debt. Most of his soldiers did not get paid until many years after their service. There simply was not enough money in the treasury.
Still the English paid for Joan of Arc 10,000 francs. Compare that to the price of a horse which in those days was from 10 to 12 francs. The average horse today is about $1000. So in today currency he paid about $1,000,000 for Joan.
She was a threat to English rule in France in a way that the English recognized.

I have a great sympathy towards Joan of Arc I should mention. In fact if we consider her mission as valid [which I do] that would mean the French were wrong for getting rid of the Monarchy.
