On the night of 12/13 April 1945 the 12 Canadian Field Company was supporting the 49th (West Riding) British Infantry Division in its assault crossing of the River Ijssel from Westervoort to Arnhem. The task of this company was to construct a Class I 40 bridge during the assault in order that the mass of supporting tanks and heavy weapons would be able to cross early on the 13 April 1945. In order to do this, a novel method of prefabricating the bridge at a safe distance upstream from the enemy, and floating its' component parts downstream into position on the required site, was used. To carry out this difficult operation, it was necessary to split the 12th Canadian Field Company into two parts, one to float downstream with the equipment, the other to get onto the bridging site as soon as possible and prepare it for the reception of the bridge.
Major Evers personally carried out a reconnaissance of the site whilst it was still under small arms fire and directed the preparations required for the reception of the bridge. Whilst under continuous enemy mortar and shell fire, Major Evers directed the construction of the bridge and approach roads on both sides of the river.
It was after nine hours and 13 minutes of the arrival of the first piece of equipment, an extraordinary short time for this nature of heavy bridge, that it was completed. This great speed was entirely due to Major Evers' superb organization and direction of the operation and it is due to him that a continuous flow of tanks and heavy supporting weapons entered Arnhem in support of the assaulting division at 100 hours on the 13th April 1945.
