“The Enemy at the Gate: Habsburgs, Ottomans, and the Battle for Europe” is what the NYT notes as: “the skirmishes and the pitched battles that raged for centuries between Habsburgs and Ottomans, and their numerous vassals on both sides, represented not so much a “clash of civilizations” as a collision of empires.”
Another point the NYT review mentions is: “The Ottomans inspired dread in their enemies; fear was part of their arsenal. But, as Wheatcroft repeatedly demonstrates, the Habsburgs were fearsome too, and perhaps even crueler than their opponents, engaging not only in full-scale massacres but in flayings, beheadings and impalements.”
