 The Marathas and Adina Beg's forces advanced to Lahore to liberate it from Afghan supremacy.Timur Shah's position at Lahore was a delicate one, Ahmad Shah Abdali was busy in Khurasan with a rebellion, the Lahore fort was in a state of disrepair, he was surrounded with a hostile population of Sikhs and he himself had very little soldiers to make a defence.So Timur Shah decided it wise to retreat against the Maratha onslaught.
