Among the key sites of battles in Russia, there is one that is very special — the Battlefield of Borodino, in the west of the Moscow Oblast. In 1812, two great armies, the Russian and the French, collided in Borodino. A museum has been created on the battlefield to commemorate this historic event. It occupies a vast territory — 110 square kilometers. All year round, there are five museum exhibitions operating here, and all the key sites in the battle are marked out by obelisks. The State Borodino Museum Reserve is the oldest museum in the world to have been created on a battlefield, having been founded on August 26, 1839. In its halls, you can find authentic weapons, equipment and soldiers’ uniforms from both armies, as well as military maps and battle drawings and paintings. Together with professional historians and reenactors, host Andrei Ivanov attempts to understand what happened on one day in the life of Russia — August the 26th, 1812. The film is based on interviews and research carried out by renowned historians of the Battle of Borodino: Lidia Ivchenko, Oleg Sokolov, Alexander Gorbunov, Alexander Sukhanov and others.
