Operation ANGER: Monument IJssel Crossing Arnhem 12/13 April 1945 The text on the plaque: "from this place on 12 April 1945 British and Canadian troops crossed the IJssel to liberate Arnhem and the West of the Netherlands from German rule. After a heavy preparatory artillery fire, the attack was launched on the German defenses at Fort Westervoort and the AKU factory in the Kleefse Waard. In small assault boats troops from the English 49th 'Polar Bear' division crossed the river. After they established a bridgehead, more units and equipment were transferred with amphibious vehicles. After four hours of heavy fighting, the enemy surrendered. The road to Arnhem and Velp was open. The construction of a pontoon bridge was started immediately."
