The practice of military deception predates Russia. "The Art of War", written in 5th century BC and attributed to the ancient Chinese military strategist Sun Tsu, describes a strategy of deception: "I will force the enemy to take our strength for weakness, and our weakness for strength, and thus will turn his strength into weakness". Early in Russia's history, in the Battle of Kulikovo in 1380, Prince Dmitry Donskoy defeated the armies of the Mongol Golden Horde using a surprise attack from a regiment hidden in forest. The tactics of that battle are still cited in Russian cadet schools.
