In 1746 the Sikhs killed Jaspat Rai, faujdar of Eminabad, in a fight. His brother Lakhpat Rai, chief minister of the governor of Lahore, Yahiya Khan, swore to destroy the Sikhs and persuaded the governor to order a general massacre.
Sikhs in Lahore were seized and executed. Then a great army, with artillery, hunted down the Sikh bands, perhaps fifteen thousand people including families, who had taken refuge in the marshes and forests of Kahnuwan near Gurdaspur. Trapped between the army, the Ravi and the hills, where the hill rajas closed the passes against them, they were cut down in May and June 1746.
Around seven thousand were killed and three thousand captured and beheaded at Lahore. The Sikhs call it the Chhota Ghallughara, the Lesser Holocaust. Within two years they had recovered.
About three thousand prisoners were beheaded in Lahore at the horse market, the Nakhas, outside the Delhi Gate; the Shahidganj memorial was later built on the spot. When Lakhpat Rai fell from power the next year he was imprisoned, handed to the Sikhs, and died in their hands.
