Some time after 1235 another Mongol force invaded Kashmir, stationing a darughachi (administrative governor) there for several years, and Kashmir became a Mongolian dependency. Around the same time, a Kashmiri Buddhist master, Otochi, and his brother Namo arrived at the court of Ögedei. Another Mongol general named Pakchak attacked Peshawar and defeated the army of tribes who had deserted Jalal ad-Din but were still a threat to the Mongols. These men, mostly Khaljis, escaped to Multan and were recruited into the army of the Delhi Sultanate. In winter 1241 the Mongol force invaded the Indus valley and besieged Lahore. However, on December 30, 1241, the Mongols under Munggetu butchered the town before withdrawing from the Delhi Sultanate. At the same time the Great Khan Ögedei died (1241).
