In a quick drive to the Rhine, Ludwigshafen fell on 21 March, and two other important river cities, Speyer and Germersheim, were secured on 24 March, clearing the Saar Palatinate. Maintaining the rapid pace, the 12th crossed the Rhine River at Worms on 28 March over pontoon bridges, advanced toward Würzburg, and captured that city along with elements of the famed 42nd Infantry Division (United States). After assisting in the seizure of Schweinfurt, the division continued toward Nuremberg on 13 April, taking Neustadt, then shifted south toward Munich on 17 April. Elements of the 12th raced from Dinkelsbühl to the Danube, where they found the bridge at Lauingen had been blown. Moving quickly they captured the bridge at Dillingen intact before demolition men could destroy it. This bridge provided a vital artery for Allied troops flooding into southern Bavaria.
