Heraclius is encamped in April 625 on the west bank of the Sarus River when Shahrbaraz's Persian forces appear on the opposite bank.

Many of his men rush impetuously across the bridge and are ambushed and annihilated by the enemy.

Emerging from his tent, Heraclius sees the triumphant Persians crossing the bridge.

Seizing his sword, he runs to the bridge and strikes down the Persian leader.

His soldiers close rank behind him and beat back the foe.

Heraclius recaptures Cappadocia and Pontus, and returns to Trapezus to spend the winter.

Shahrbaraz retreats in good order, and is able to continue his advance through Asia Minor towards Constantinople.
