 Unfortunately, because of pressure from the Germans in the northern part of the 2nd Army bridgehead, the British were having trouble completing their bridges at Xanten and were, therefore, bringing most of their traffic across the river at Wesel.With Montgomery allowing use of the Wesel bridges to the 9th Army for only five out of every 24 hours, and with the road network north of the Lippe under 2nd Army control, General Simpson was unable to commit or maneuver sufficient forces to make a rapid flanking drive.By 28 March, the 8th Armored Division had expanded the bridgehead by only about and still had not reached Dorsten, a town about east of the Rhine, whose road junction promised to expand the XVI Corps′ offensive options.
