Napoleon's Military Engagements
In the Peninsular War, Napoleon aimed to expand his empire by invading the Iberian Peninsula. However, he faced strong resistance from the Spanish and Portuguese forces, who employed guerilla warfare tactics. Although Napoleon's troops initially made some gains, they were ultimately unsuccessful in fully subduing the peninsula and faced heavy losses.
In his invasion of Russia, Napoleon led the Grande Armée in a campaign to conquer Russia. Initially, the French forces saw success and made it to Moscow. However, they faced challenges due to the harsh Russian winter, lack of supplies, and the Russian army launching counterattacks. Ultimately, the invasion was a failure for Napoleon, resulting in significant casualties and retreat of his troops.
