The war with Napoleon brought quite a lot of damage, and Russia and France. Fortunately, we were able to withstand the attack of Napoleon and won this war. I believe that war in our world. The official reason for war was the violation of the conditions of the Tilsit peace Treaty Russia and France. Napoleon was considered insulting to a requirement of the Emperor Alexander to withdraw troops from the Duchy of Warsaw and Prussia. The war of 1812 was inevitable. Napoleon led a huge 600-strong army crossed the Niemen June 12, 1812. Russian army, numbering only 240 thousand people, was forced to retreat deep into the country. In the battle of Smolensk Bonaparte failed to win a complete victory and split the combined 1st and 2nd Russian armies.
