"Commander", I cried out to Kozietulski, "the Emperor orders you to commence the charge at once!" Montbrun made an exclamation and a gesture of astonishment, without daring to contradict me. Piré however declared: "It is impossible." (Major de Ségur, battle participant and memorialist.) This booklet is the English translation of a French-Russian analysis of the Battle of Somosierra. It provides the Napoleonic enthusiast with insights on the men involved , an overview of the battlefield and eyewitness accounts. The famous charge carried out by the Polish Light Cavalry Regiment of the Guard is also put into perspective and makes interesting reading.
