The common Russian-Baltic history has developed over many centuries. This book tells about the events of the Patriotic War of 1812 that took place on the territory of the Baltic States and, due to a number of circumstances that turned out to be little known among a wide range of readers. In crushing the pan-European aggression directed by Napoleon Bonaparte, there is a share of the military labor of the defenders of Riga and Dinaburg in 1812. It is our duty to remind that. The popularization and dissemination of historical knowledge is the main goal of this book.
