"Shakespeare," in the play "Henry VI," describes the English campaigns conducted in France during this period. In doing so he displays an intimate knowledge of the country where the battlers were fought, and mentions the cities of Orleans, Blois, Tours and Poictiers.
There is a fact that Francis Bacon in 1577 visited the English battle grounds so vividly described in "Henry VI," and also stayed in Orleans, Blois and Tours, which are immortalized by "Shakespeare," and that he also spent three months in Poictiers, where Edward the Black Prince won his great victory.
