Genghis Khan and the Making of the Modern World - Jack Weatherford [117]
In November 1257, unconvinced of the Caliph’s power to speak for either God or the entire Muslim population, Hulegu began to march toward Baghdad. He approached more cautiously than his grandfather would have done, but nevertheless with the same set of proven Mongol strategies and tactics. To supplement his own army, Hulegu summoned the armies of the vassal states of Armenia and Georgia, as well as a variety of Turkic tribes. Thus, while the main army approached in a wide arc from the north and the east, the others approached from the north and west. Although the Tigris and Euphrates Rivers had historically served as natural barriers to foreign attacks on Mesopotamia, the Mongols easily moved back and forth across the rivers with a series of pontoon boats. As the invading armies advanced, they set the local population to flight toward the safety of the fortified city. By the final week of January 1258, the invading armies had encircled the city and occupied the extensive suburbs beyond the city walls, filling the city to its maximum with refugees.
Before commencing the attack, Hulegu sought to exploit political, religious, and ethnic divisions within Baghdad by forging secret ties to the Christians within the city. Because his mother and his two wives were Christians, as well as many of his own men, Hulegu cultivated contacts and nourished respect within the Christian communities across the Middle East, and he had maintained good relations with his Christian vassal kingdoms, Georgia and Armenia. Taking advantage of these connections, Christian envoys secretly slipped back and forth between the city and the Mongol camp, bringing vital reconnaissance to Hulegu and carrying back promises of special treatment to the Christians and other minorities in the city. As a sign of the special favor that the Christians would enjoy under his rule, Hulegu exempted Christian priests from kowtowing at court, since they bowed only to God. Hulegu exploited the fears of the Christians of Baghdad as a small minority in a sea of potentially hostile Muslims. He fed the dreams of Christians and Jews of finally freeing themselves from Muslim domination.
The Caliph also tried to use to his own benefit the close ties of the Mongols and the Christians. He summoned the Catholikos Makikha, the patriarch of the Christian church, and dispatched him and a Muslim minister to negotiate with the Mongols. He offered to make a formal submission, pay enormous tribute, and to read Friday prayers in the mosque in the name of the Great Khan, thereby officially acknowledging his subservience to Mongol rule. Hulegu scoffed at the offer. He knew that he was already too close to victory to settle for such trifles—not when all the wealth of the richest city on earth could easily be his.
The Mongols showed their traditional ability to improvise and use whatever material presented itself as a possible weapon. The largest objects in the vicinity were the tall date palm trees that the Arabs had cultivated and nourished for centuries. The Mongols chopped them down, and turned the trunks into lethal missiles that they fired at the city. Lacking sufficient wood to encircle the large city of Baghdad as the Mongols had done with the cities of Russia, Hulegu nevertheless surrounded the city with a deep ditch and a rampart and began the assault with a terrifying bombardment of the city. The Arabs knew of the use of flamethrowers in combat, but until this point had not encountered the military power of gunpowder.
The Mongols had changed the formula of gunpowder to provide enough oxygen to make it ignite in one rapid blast rather than in the
