The 1291 siege of Acre was the Alamo of the Christian Crusades — the final bloody battle for the Holy Land. After a desperate six weeks, the beleaguered citadel surrendered to the Mamluks, bringing an end to Christendom's two-hundred year adventure in the Middle East.In , Roger Crowley delivers a lively narrative of the lead-up to the siege and a vivid, blow-by-blow account of the climactic battle.

A gripping depiction of the crusader era told through its dramatic last moments, offers an essential new view on a crucial turning point in world history.
