Answer
Attrition warfare, employed by Kutuzov against Napoleon, involved gradually weakening the enemy's forces through continuous attacks and skirmishes. By avoiding decisive battles and engaging in hit-and-run tactics, Kutuzov aimed to deplete Napoleon's army's morale, supplies, and manpower. This strategy allowed the Russian army to conserve its strength while inflicting significant losses on the French, ultimately contributing to Napoleon's defeat in the Russian campaign.
