Defence Day

Defence Day ( ALA-LC: ) is celebrated in Pakistan as a national day to commemorate the sacrifices made by Pakistani soldiers in defending its borders. The date of 6 September marks the day in 1965 when Indian troops crossed the international border to launch an attack on Pakistani Punjab, in a riposte to Pakistan's Operation Grand Slam targeting Jammu. While it is officially commemorated as an unprovoked surprise attack by India, repulsed by the Pakistan Army despite its smaller size and fewer armaments, the narrative has been criticised by Indian commentators as representing false history.

Context of the 1965 War
The Indo-Pakistani War of 1965 began with Pakistan, after India increased aggression in Kashmir, sending Mujahid into the Kashmir Valley to incite the population into rebellion and dislocate the local installations. In the second stage, on 1 September, it launched a tank attack, dubbed Operation Grand Slam, towards the Akhnoor bridge in the Jammu Division. It was intended to be a "short and swift, fait accompli operation". According to scholar Shuja Nawaz, the Pakistani general intended to capture the Akhnoor bridge and swing towards Jammu to cut off India's communications with Kashmir Valley. The Pakistanis had ignored the Indian Prime Minister's (then Lal Bahadur Shastri's) warnings that India would retaliate against Pakistan if Kashmir were attacked.

On 6 September, according to its "pre-declared strategy" of riposte, the Indian Army crossed the international border in Punjab intending to cut off the Grand Trunk Road near Lahore. Another Indian objective was to capture the Lahore Cantonment. The attack came as a surprise to the Pakistani commanders. According to Air Marshal Nur Khan, the Army Chief General Musa Khan told President Muhammad Ayub Khan on the second day of the war that the Army had run out of ammunition. However, the statement given by Air Marshal Nur Khan was challenged by the Indian commanders themselves, Lt. Gen Harwant Singh himself stated that the heaviest firing by the Pakistan Army was started after ceasefire. He states that the Army suffered heavy losses in the war. On 23 September, Pakistan accepted a UN-mandated ceasefire.

Pakistan instituted the Defence of Pakistan Day to commemorate the day when the Indian forces crossed into Pakistan. The Pakistan official narrative states that "[the] Indian forces sneaked [sic] into the Wagah border and the Pakistan armed forces, when alerted, put up a valiant defence of the motherland and drove them back, thus taking its name as the Defence of Pakistan Day." Air Marshal Nur Khan commented, "It was a wrong war and they misled the nation with a big lie that India, rather than Pakistan, had provoked the war and that we (Pakistanis) were the victims of the Indian aggression."
