The Battle of Chawinda was a major engagement between Pakistan and India in the Second Kashmir War as part of the Sialkot campaign. It is well-known as being one of the largest tank battles in history since the Battle of Kursk, which was fought between the Soviet Union and Nazi Germany in World War II.The initial clashes in Chawinda coincided with the Battle of Phillora, and the fighting here intensified once the Pakistani forces at Phillora retreated. The battle came to an end shortly before the United Nations Security Council mandated an immediate ceasefire, which would formally end the hostilities of the 1965 war.
