I'm currently reading Reed Browning's 1993 "The War of the Austrian Succession" and have just seen the French capture Prague.
Poor old Austria ia at the absolute nadir of it's fortunes.
Still, I suppose the only way is up!
It's quite a readable book that seems to cover it's subject very well. It's refreshingly free of an Anglo-centrist point of view which is a nice change of pace from a lot of the history of the era I read (considering that English is the only language I read with any fluency, I suppose that's to be expected!).
