'Our raids were sudden and fierce'
In August 1965, what looked like an indigenous uprising spread like a jungle fire across the part of Kashmir under Indian control.
But Operation Gibraltar was an attempt by the Pakistani government to start a rebellion in the disputed region.
Qurban Ali, 71, is one of the men who fought the Indian troops, as a soldier in the Pakistani army's Azad Kashmir Regiment.
He told BBC News his memories of the time.
