An example of Mongol tactics from the Battle of Kalka River (1223)
While Genghis Khan was consolidating his conquests in Persia and Afghanistan, a force of 40,000 Mongol horsemen pushed through Azerbaijan and Armenia. They defeated Georgian crusaders, captured a Genoese trade-fortress in the Crimea and spent the winter along the coast of the Black Sea. As they were headed back home they met 80,000 warriors led by Prince Mstitslav of Kiev. The battle of Kalka River (1223) commenced. Staying out of range of the crude weapons of peasant infantry, and with better bows than opposing archers, they devastated the prince's standing army. Facing the prince's cavalry, they faked a retreat, drawing the armored cavalry forward, taking advantage of the vanity and over-confidence of the mounted aristocrats. Lighter and more mobile, they strung out and tired the pursuers and then attacked, killed and routed them
