In August, 1759, Ahmad Shāh Abdālī crossed the Indus, driving the Marāthā outposts before him, and Sābājī retreated rapidly towards Delhi. Ahmad marched to Jammū, where he levied tribute from the Rājā, Ranjīt Deo, and then continued his advance towards Delhi. As the country west of the Jumna had been denuded of supplies by the frequent passage of Marāthā armies, he crossed the Jumna into the northern Dūāb, but sent a force by the western route to deal with Dattājī Sindia who, having abandoned the siege of Shukartār, had crossed the Jumna and was marching towards Sirhind to oppose his advance.
