Genghis Khan and the Making of the Modern World

by Jack Weatherford

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 traditional slow burn of the firelance or of rockets. Such instantaneous burning produced an explosion rather than a fire, and the Mongols harnessed these explosions to hurl a variety of projectiles. Craftsmen made some of the tubes small enough that a single man could operate them and thus fire out arrowheads or other metal projectiles.
