1. India had lost a war against China in 1962. 2. Pandit Nehru had died in 1964 3. Pakistan saw this as an opportune moment to strike against India
This battle is of significance largely due to the fact that it was the battle which turned the tide of the 1965 war towards India. Until this point, Pakistan had made significant territorial gains. However it was with this battle, one involving some amazing tactical moves on part of India, that boosted the morale of the Armed Forces to such an extent that by the time the ceasefire was implemented, Indian forces had reached Lahore.
