Indo-Pak War of 1965
Pakistan and India went into their second military conflict on 6 September 1965.
Pakistan launched Operation Gibraltar to infiltrate forces into Jammu and Kashmir to precipitate an insurgency against rule by India. The mission ultimately failed and both countries entered into a full-scale military conflict. The war continued for 17 days and caused thousands of casualties on both sides. The war also witnessed the largest engagement of armored vehicles and the largest tank battle since World War II.
The war ended after 17 days in result of diplomatic intervention by the Soviet Union and United States. Both countries claimed victory and war concluded with ceasefire mandated by the United Nations. It was a successful defence of Lahore but there were no paramount territorial changes as agreed in Tashkent Declaration to formally resolve the war on 10 January 1966 at Tashkent, Uzbek Soviet Socialist Republic.
