On the 11th and 12th April 5th RTR supported 53rd Welch Division, who had crossed the River Weser, only to run into trouble at Rethem, 10 miles further on.
Here they met the 2nd Marine Division, from Hamburg, who like most marines gave their best, holding out for 4 days.
During this operation, 5th RTR destroyed eight 88mm and several 125mm Flack guns defending the railway line.
