Meerut (First Mongol Invasion of India).
This place was besieged in 1398 by the Tartars, under Tamerlane. It was considered impregnable, and Tamerlane commenced mining operations, but these methods were too slow for his followers, who by means of scaling ladders carried the fortress by storm, and massacred all the inhabitants. Tamerlane afterwards completed his mines and destroyed all the defences.
