<P> Some writers have speculated that the operation's objective may also have been retaliation for India's Operation Meghdoot in 1984 that seized much of Siachen Glacier . </P> <P> According to India's then army chief Ved Prakash Malik, and many other scholars, much of the background planning, including construction of logistical supply routes, had been undertaken much earlier . On several occasions during the 1980s and 1990s, the army had given Pakistani leaders (Zia ul Haq and Benazir Bhutto) similar proposals for infiltration into the Kargil region, but the plans had been shelved for fear of drawing the nations into all - out war . </P> <P> Some analysts believe that the blueprint of attack was reactivated soon after Pervez Musharraf was appointed chief of army staff in October 1998 . After the war, Nawaz Sharif, Prime Minister of Pakistan during the Kargil conflict, claimed that he was unaware of the plans, and that he first learned about the situation when he received an urgent phone call from Atal Bihari Vajpayee, his counterpart in India . Sharif attributed the plan to Musharraf and "just two or three of his cronies", a view shared by some Pakistani writers who have stated that only four generals, including Musharraf, knew of the plan . Musharraf, however, asserted that Sharif had been briefed on the Kargil operation 15 days ahead of Vajpayee's journey to Lahore on 20 February . </P> <Table> <Tr> <Th> Date (1999) </Th> <Th> Event </Th> </Tr> <Tr> <Td> 3 May </Td> <Td> Pakistani intrusion in Kargil reported by local shepherds </Td> </Tr> <Tr> <Td> 5 May </Td> <Td> Indian Army patrol sent up; Five Indian soldiers captured and tortured to death . </Td> </Tr> <Tr> <Td> 9 May </Td> <Td> Heavy shelling by Pakistan Army damages ammunition dump in Kargil </Td> </Tr> <Tr> <Td> 10 May </Td> <Td> Infiltrations first noticed in Dras, Kaksar, and Mushkoh sectors </Td> </Tr> <Tr> <Td> Mid-May </Td> <Td> Indian Army moves in more troops from Kashmir Valley to Kargil Sector </Td> </Tr> <Tr> <Td> 26 May </Td> <Td> IAF launches air strikes against infiltrators </Td> </Tr> <Tr> <Td> 27 May </Td> <Td> IAF loses two fighters--MiG - 21 and MiG - 27; .
