What was the major reason for neopoleons defeat during his invasion of russia

In 1812, Napoleon invaded Russia with about 600,000 men and over 50,000 horses. His plan was to bring the war to a conclusion within twenty days by forcing the Russians to fight a major battle. Just in case his plans were off, he had his supply wagons carry 30 days of food. I hope this helps :D

Napoleon failed to conquer Russia in 1812 for several reasons: faulty logistics, poor discipline, disease, and not the least, the weather.

i believe it d) heterogeneous

an economic reason that the south needed a reconstruction plan is that plantations, factories, and other businesses were destroyed during the war.
