When a rumour spread that Nader had been assassinated by a female guard at the Red Fort, some Indians attacked and killed 3,000 Afsharid troops during the riots that broke out on the night of 21 March. Nader, furious at the killings, retaliated by ordering his soldiers to carry out the notorious
qatl-e-aam(massacre – qatl = killing, aam = common public, in open) of Delhi.
On the morning of 22 March, Nader Shah sat at
Sunehri Masjid of
Roshan-ud-Daulah. He then, to the accompaniment of the rolling of drums and the blaring of trumpets, unsheathed his great battle sword in a grand flourish to the great and loud acclaim and wild cheers of the Afsharid troops present. This was the signal to start the onslaught and carnage.
