otherwise. Therefore, as they expanded into other areas and conquered other people, their troop numbers increased. Exemplifying this is the Battle of Baghdad, during which many diverse people fought under Mongol lordship. Despite this integration, the Mongols were never able to gain long-term loyalty from the settled peoples that they conquered. Ground tactics The tumens would typically advance on a broad front, five lines deep. The first three lines would be composed of horse archers, the last two of lancers. Once an enemy force was located, the Mongols would try to avoid risky or reckless frontal assaults. Instead they would use diversionary attacks to fix the enemy in place, while their main forces sought to outflank or surround the foe. First the horse archers would lay down a barrage of arrow fire. Additional arrows were carried by camels who followed close by, ensuring a plentiful supply of ammunition. Flanking In all battlefield situations, the troops would be divided into separate formations of 10, 100, 1,000 or 10,000 depending on the requirements. If the number of troops split from the main force was significant, for instance 10,000 or more, these would be handed over to a significant or second-in-command leader, while the main leader concentrated on the front line. The leader of the Mongols would generally issue the tactics used to attack the enemy. For instance the leader might order, upon seeing a city or town, "500 to the left and 500 to the right" of the city; those instructions would then be relayed to the relevant 5 units of 100 soldiers, and these would attempt to flank or encircle the town to the left and right. Encirclement and opening The main point of these maneuvers was to encircle the city to cut off escape and overwhelm their enemies from both sides. If the situation deteriorated on one of the fronts or flanks, the leader from the hill directed one part of the army to support the other. If it appeared that there was going to be significant loss, the Mongols would retreat to save their troops and would engage the next day, or the next month, after having studied the enemies' tactics and defenses in the first battle, or again send a demand to surrender after inflicting some form of damage. There was no fixture on when or where units should be deployed: it was dependent on battle circumstances, and
