How did geography play a role in France's invasion of Russia?

Answer:As well as the sheer scale of the country and the immense distances that he had to contend with on the way to Moscow and the retreat thereafter, another major geographical feature was the climate.

Explanation:

In the first week of the invasion alone, over 10,000 horses were lost due to exertion in the intense summer heat. This number continued to rise dramatically as Napoleon pressed on, depriving him not only of much of the cavalry he would later need to cover his retreat but also of the ability to establish supply lines over the vast distances.
