Reddit reviews Chronicles of the Crusades (Penguin Classics)

If anybody is interested in some first-hand accounts of the Crusades I'd recommend the translations of Villehardouin and Joinville, which focuses on the Fourth, Seventh, and Eight Crusades, Robert of Clari, which is a soldier's account of the Fourth Crusade, and if you can find it Virginia Gingerick Berry has translated Odo of Deuil's account of the Second Crusade. If you are in higher education it may be available through humanitiesebook if your institution is subscribed. It details Louis VII disastrous attempt to crusade as told by his chaplain. Lots of theories on why it was written and when. This list is mainly to do with French history and is in no way exhaustive.

Lots of first-hand accounts in Chronicles of the Crusades: Jean de Joinville's lively and detailed account of Louis VII's mid-13th century crusading in the Holy Land features lots of vivid battles and Geoffrey de Villehardouin's eyewitness account of the sack of Constantinople in 1204.

EDIT: Oh yeah, Jean de Froissart's account (lots of free translations on line) of some major battles of the 100 Years' War is a classic.
