This is a remarkable account of the fourth crusade, if only because the author was there, and was a major player, as a Marshall. The book is written in a very reserved style, and Villehardouin makes no effort whatsoever to promote himself. Unfortunately, by so doing he buries the debates that must have gone on prior to major decisions, so unless something was obvious, it is unclear why certain events happened. Nevertheless, you should be able to reach your own conclusions. The account more or less overturns a lot of my assumptions of the time. Castles changed hands frequently, largely because the defenders ran. How they ran is not really explained, nor how, if a castle was surrounded, those inside could send messages for help. Nevertheless the story exposes the base character of many of the participants. So many "took the cross", and then somehow found a way not to turn up, or leave the crusade at the first opportunity. The nature of the battles is not shown, but you can read into it the powerful nature of the knight. This account is limited, but in my opinion, indispensable if you want to understand the nature of this crusade.
