How did the Russians fight back when napoleon invaded?

When Napoleon invaded Russia in 1812, the Russian strategy involved a scorched earth policy, retreating deeper into their territory while destroying food supplies and resources that could benefit the French army. The harsh winter and vast distances further weakened Napoleon's forces. Additionally, Russian forces engaged in guerrilla tactics, conducting skirmishes and ambushes to harass the French troops. This combined strategy ultimately led to significant losses for Napoleon and contributed to his eventual retreat.
