Why did it happen? (Tashkent Declaration)

This is the page that gives the explanation for why events occur the way they do in Tashkent Declaration and the difference between them and the events in OTL.

Indo-Pakistani War of 1965
Proper intelligence about India's ammunition reserves pushes the Prime Minister's Office to attempt to delay the ceasefire. In the delay, the Indian forces capture Lahore on 23 September. In OTL, the Indian forces were just outside Lahore Intl. Airport on 21 September (when the ceasefire came into effect) and were about to capture Lahore, however the wrong information that India's ammunition reserves were almost empty prompted the Prime Minister's Office not push for a delay of the ceasefire.

The capture of Lahore dealt a severe blow to Pakistan and the ceasefire came to effect on 24 September.
