Name of Field Marshal M.I. Kutuzov is widely known not only in Russia, but also outside the country. Having begun his military career at the age of 19, he was devoted to the Fatherland until the end of his days, defeating the enemy on the battlefield more than once. Back in 1786, Mikhail Illarionovich created instructions for battalion commanders, where he outlined in detail the basics of infantry and ranger services. Kutuzov actively applied all military theory in action, which allowed him to defeat the indestructible army of Napoleon. The publication includes a treatise on infantry and ranger service - a brilliant example of the work of a commander, as well as the most striking excerpt from the book by F.M. Sinelnikov “Life, military and political deeds of His Grace Field Marshal General, Prince M.I. Golenishchev-Kutuzov-Smolensky", dedicated to the War of 1812 and subsequent events.
