September 6 is the most important day because this day is celebrated in the memory of those who died in the War between Pakistan and India which was fought in the year 1965.
Openly both the countries Pakistan and India went on War with each other a minor combat that proceeded to war in September 1965. India attacked the Pakistani territory from the Lahore Burki sector during very dark night. India launched her forces and attacked Pakistan across the international border without any warning or an announcement of war. This rude action of India, which claims to be the largest democracy in the World, was in utter violation of International laws. India arrogantly swept aside her international commitments in her desire to conquer the region.
India’s attack against Lahore was held and beaten back with heavy losses to the attackers. The Pakistan Army units defending on the ground, supported by the Pakistan Air Force were able to blunt the Indian offensive attack and roll it back. Two days later on 8th September India launched its main attack against Sialkot using its armored division and other strike formations. What results has been described as the largest tank battle since the Second World War It was a hard and bitter struggle fought over many days and nights resulting in fatalities on both sides. In the end the Indian main attack was held and severely attacked Pakistan. Its armored division was force to withdraw owing to very high losses in manpower and material. South of Lahore, Pakistan launched its own counter attack and captured Indian attack. 
During the 1965 war every citizen of the country was firmly united behind the government, although it was a military one. The national priorities were clear and unambiguous in those days, any hazard to the country called for unity and abundant support to the government and the armed forces. There was no question of any political party or leader taking advantage of the war to rebuke the government for political or personal gain.
Pakistan emerged from the September 1965 war with India, as a strong and self confident nation, proud of itself and its armed forces. It was a nation that was united in facing the danger from India. 6 September is day of national unity and full support for the armed forces. On 6th September 1965 with the nations support the Armed Forces of Pakistan drive away the India’s naked aggression across the international border and made her pay a price for it by capturing four times more territory than India and forcing her to accept a ceasefire, fore her to return to the negotiating table. The day of 6th September is a finest hour of glory, and a day to be remembered by future generations of soldiers and civilians of Pakistan.
