Harsa's military exepansion in the Deccan was checked by Pulkesin II. When Pulkeshi II pushed forth up to the Narmada, he came face to face with Harshavardhana of Kanauj who already had the title Uttarpatheshvara (Lord of the north). In a decisive battle fought on the banks of the river Narmada, Harsha lost a major part of his elephant force and had to retreat. The Aihole inscription describes how the mighty Harsha lost his harsha (joy) when he suffered the ignominy of defeat.
