Final answer:
The invasion of Russia led to the majority of Napoleon's troops dying from starvation, disease, and the cold.
Step-by-step explanation:
The invasion of Russia led to the majority of Napoleon's troops dying from starvation, disease, and the cold. In 1812, Napoleon launched an invasion of Russia with around 600,000 soldiers. However, the Russian army adopted a scorched-earth policy, destroying their own resources to prevent Napoleon's troops from finding food and shelter. This, combined with the harsh Russian winter, caused massive casualties among Napoleon's forces.
