Major–General Onkar Singh Kalkat, PVSM, (3 December 2004) was an Indian military officer in the British Indian Army and later the Indian Army. Soon after the partition of India in 1947, he stumbled upon the plans for an Operation Gulmarg, which were apparently Pakistani plans to attack the princely state of Kashmir, two months before they were to commence. Even though he conveyed the information to the Indian authorities, he was not taken seriously. Senior Indian officials including the-then Defence Minister of India Sardar Baldev Singh, Brigadier Kalwant Singh and the DGMO, Col. P. N.

Early life Onkar Singh Kalkat was a postgraduate in economics from the University of Delhi.

Murry, a British officer; who were waiting to go back to India and England, respectively. It was then in August 1947 that Kalkat stumbled upon information related to Pakistan's invasion of Kashmir, Operation Gulmarg, that was to commence in October. Kalkat was authorised to open letters for Brigadier CP Murry in his absence. On 20 August 1947, Kalkat opened one such letter from General Frank Walter Messervy, and found attached the plans for Operation Gulmarg.
