A fine look at one of the major battles of the Peninsula War. A strength of this book is an examination of Wellington's tactical (i.e. battlefield) system, both in regards to how he fought this battle, and what he learned here and applied later. Field takes a detailed look at the dynamic between British line formation and the French column formation, which has been a "controversey" for well over 100 years. I found his take on this satisfying---the French and their columns had defeated every major power in Europe, but had been deployed with much more subtlty and in combination with the line much more often and effectively than in the Peninsula, especially at Talavera Field posits that the French system was to use skirmishers and artillery fire to weaken the enemy and then close with the column to finish them off. The British were able to counter the French skirmishers and lie down or hide behind hills to avoid artillery, so rather than advancing against a shaken and worn out defender, the British were better able to stand and fight. It did not hurt that the British were the only army in Europe to practice and encourage aimed fire.
The narrative description of the battle itself is concise and fairly straight forward. Field does a good job describing the terrain and how it influenced the fighting and of mixing in first hand accounts with the larger overview.
In all, a well structured and written book about a bloody and very close battle.
