The Mongols bypass villages to maximize speed, intending to strike directly at Delhi itself. At the Jumna River, Mongol forces under Qutlugh defeated Zafar Khan, and are forced to retreat to Delhi. News of the defeat causes thousands to abandon their homes, the capital is soon flooded with refugees. The streets, the markets and the mosques become overcrowded. Meanwhile, the merchant caravans headed for Delhi are interrupted by the Mongols.
