The Allies arrived outside the fortress of Donauwörth in the afternoon of the 2nd July much to the surprise of the Bavarian defenders. Marlborough ordered an immediate attack on the outer strong points of the defences. This had the effect of pulling many men from the central positions in Bavarian defences. This achieved Marlborough then attacked the central positions and drove a wedge between the two parts of his opponents forces. By 20.15 hrs the fortress had fallen and the town of Donauwörth fell soon after. The allies had secured a major bridge across the Danube.
