Final answer:
Napoleon's invasion of Russia in 1812 was a failure due to losses, a scorched-earth strategy, and harsh winter conditions.
Step-by-step explanation:
Napoleon's invasion of Russia, which took place in 1812, was ultimately a failure. The campaign was launched with the aim of forcing the Russian Empire to submit to French dominance, but it resulted in significant losses and ultimately contributed to Napoleon's downfall. The Russian army employed a scorched-earth strategy, destroying resources as they retreated, which severely impacted Napoleon's ability to sustain his army. The harsh Russian winter, combined with a lack of provisions and the Russian army's resistance, led to the decimation of Napoleon's Grand Army.
