Geography and harsh weather played a major role in napoleons defeat during his invasion of russia hungary germany great britain

During his invasion of Russia. When his army tried to invade, they were severely under dressed, so majority of his men died due to hypothermia because of the extreme cold climate. So the Russians were able to push Napoleon's army out of Russia. I hope this helps
