In 2015, India commemorated the bitter war of 1965 that broke out after Pakistan launched Operation Gibraltar to infiltrate into Indian territory in Jammu & Kashmir. The 17-day war that left thousands dead on both sides may have continued had the then Soviet Union and the US not engineered a ceasefire. Since it was an engineered ceasefire, both countries claimed victory.
Battles were fought at various places. One of the most unusual was the Battle of Tanot Post in Rajasthan, manned by a handful of Indian troops mounted on camels. They were from the mounted squadron of 13 Grenadiers (Ganja Jaisalmer) and 4 Rajasthan Armed Constabulary (later 13th battalion of the Border Security Force). The little post was heavily out-numbered by Pakistani forces which bombarded them with about 3,000 shells of various calibres but they repulsed the enemy for three days, till reinforcements arrived. 
Three of the most memorable battles of the 1965 war were:
Battle of Phillora, fought in the Sialkot sector, is believed to be the biggest tank battle after World War II. On Sept 10, 1965, Indian troops launched an attack on Phillora, Pakistan with at least four armoured regiments. Indian troops captured Phillora on September 11 and the battle ended the next day when the Pakistani forces retreated. 
Battle of Asal Uttar, fought from Sept 8-10, 1965, involved the capture of Khem Karan town, about 5 km inside the Indian border. After three days of fighting, the Indian troops pushed back the Pakistani soldiers and regained control of Khem Karan. India caught or destroyed about 100 Pakistani tanks and lost 10. About 60 of the captured tanks, mostly of the Patton make, were on display near Bhikiwind village. The place they were kept on show was renamed Patton Nagar. Later, they were re-positioned at different military stations across India as souvenirs of a bitter war.
Battle of Burki was fought over the town of Burki, a strategic location barely 10 km south-east of Lahore in Pakistan. Indian soldiers fought Pakistani troops well-entrenched in trenches and dug-outs and Burki was captured on September 11. Captured areas were returned in accordance with the Tashkent Declaration that signified the end of the war.
