"Poker Lessons from Richelieu"

Such is the title of this book review, which makes the case that the famous Cardinal was marked more by a gambler's sentiment than a manipulator's.  Since we were just talking about the Thirty Years War, here is a relevant section:

 In 1618, what would become known as the Thirty Years’ War broke out -- Europe’s last great spasm of religious warfare, in which a furious conflict between a series of Protestant states, on one side, and the House of Hapsburg and its Catholic allies, on the other, tore the center of the continent apart. France, a Catholic state itself, nevertheless intervened on the Protestant side, hoping to supplant the Austrian and Spanish Hapsburgs as the strongest power in Europe. 

Richelieu initially felt that France could do no more than subsidize Protestant efforts and engage in strictly limited military campaigns. Ironically, he feared treachery from the Huguenots, France’s own small Protestant minority, who had lingering grievances against the French state and control of several strategic towns, including the Atlantic port of La Rochelle. Realizing that he had to address the Huguenot threat before intervening seriously abroad, in 1627 Richelieu laid siege to La Rochelle and starved the city into submission. (By the end of the operation, even the rats had disappeared, and the starving locals were reduced to eating boiled shoe leather.)

La Rochelle has one of the more interesting civic histories.
