The correct answer is B) French defeat.
Indeed, Napoleon had assembled one of the greatest land armies of his time (450,000 men) and he invaded Russia during the early summer of 1812. Russians employed a brutal scorched earth tactic, depriving Napoleon’s troops of anything that could be used to feed them or their horses or to house them.
They lost the Battle of Borodino outside Moscow in September but then burned Moscow to the ground in order to prevent the French from spending the winter there. Their retreat was catastrophic. Harassed by the extreme cold weather and by Russian attacks, only 40,000 of the original survived the Berezina Battle in November.
Napoleon’s Empire would never recover from such defeat and was ultimately defeated and removed from power in 1814.
