Why was Napoleon Bonaparte unsuccessful in taking over Russia

Napoleon failed to conquer Russia because of faulty logistical planning and ignorance of the Russian territory and infrastructure. The soldiers had to forage for their own food and there was problems with disease and the weather.

Explanation:

Napoleon failed to conquer Russia in 1812 because his previous military successes were based on the concentration of his forces at key places to destroy his enemy. He would move his troops fast and basically counted on them to be able to forage the local surroundings for food. But Russia had a poor road system and the 600,000 men Napoleon brought had to use the same roads so the first soldiers left little for the later soldiers who were passing by. The Russians also adopted a scorched earth policy so that made it harder for the soldiers to find food. Soldiers began to forage further away from the roads for food and the horses started to die.
