Crossing the Divina July 6th, 1941 Two weeks in to the Barbarossa Campaign the 4th Panzer Army was moving eastward towards the Divina River. The men of the 1st Engineer Battalion of the 7th Panzer Division near the town of Ulla, began to make a river crossing across the Divina. As the engineers made their way, the Soviets launched a series of counter attacks to stop them. While the Soviets came close to destroying the bridgehead, German tactical skill saved the day.
