In the process of his work on a volume of documents on Juárez, Jorge L. Tamayo, the editor of this volume, found a number of Zaragoza letters. These, along with some other unpublished and published material, have been brought together for this book issued on the centenary of Zaragoza’s defeat of the French at Puebla. Tamayo has a forty page introduction and a fifteen page catalog of the men mentioned in the documents.

The letters and documents cover the time span January-August 31, 1862. Zaragoza’s letters stress the need for reinforcements, disagreements among the Mexican military leaders, the high morale of the troops, and the defeat of the French on May 5.
