For one with only an hour to an hour and a half to dedicate to the battle a very good introduction. The book starts by providing some perspective from both the English and French sides (i.e., geopolitical situation, goals, etc.). Professor Nicole then provides a description of the forces involved, their leaders and strategies and goals. Lastly he goes through what transpired through the battle, something that every military officer should read as it involved, for the French, a combination of just about everything that could go wrong going wrong thanks to their own ineptitude.
Firstly, the Italian crossbow mercenaries, who victory depended upon so much were misused. They were forced into action in the rain when their crossbows were of limited value as the strings were wet. The English bowmen, on the other hand, did not have this problem as they were able to string their bows just before going into action (thus insuring they were dry and were working at maximum efficiency). As if this was not bad enough, the Italians were forced to face the English with their eyes to the sun. This was quite a problem as the cross bow must be targeted against specific targets as opposed to the English bows which were an "area saturation" weapon. In addition, the Italians were deployed without the benefit of their shieldholders, troops they hid behind when they had to reload their crossbows. As a result, when the inevitable counter battery of English arrows hit them they were out in the open and unprotetected. In the resulting retreat, thanks again to French ineptitude, the French thought the retreating Italians were in route while in reality they were running back to their lines to the shieldholders. They proceeded to kill a large number of the routed Italians due to "cowardice".
This battle is trully remarkable in that it showed just about everything going wrong. The result was, not surprisingly, a total French defeat.
