This is the second volume of the three expected albums from The Polish Army under Napoleon's command Series. The format refers to the books of The Army of the Duchy of Warsaw Series. However, it has more pages and 86 colour plates, the biggest number so far. The gouaches were once again rendered by Ryszard Morawski who is an acknowledged expert on military uniforms, especially from the Napoleonic Era. The text was written by Andrzej Nieuwazny, a well-known historian specialized in the Napoleonic Era, the author of the book about the artillery of the Duchy of Warsaw. Our current offering describes Polish formations of the Napoleonic Guard. A considerable part of the text is dedicated to the regiments of Light Horsemen and their combat path through Spain, Austria, Russia, Germany and France. The author faithfully reconstructs the course of the outstanding charge of Somosierra that took place exactly 200 years ago.
