On March 18 the Regiment started out in pursuit of the 11th Armored Division's tanks which were decimating the German forces to the south. The 2nd Battalion passed through Hahn at 1115. The 3rd Battalion moved to the southeast to reach the town of Rhaunen. Sniper fire was received. A 43rd Cavalry platoon of the 11th Armored had been ambushed on the outskirts of the village resulting in nearly all of its vehicles being destroyed and most of its men and officers killed or seriously wounded. Co. L moved on to the next town which had been secured by the tankers of the 21st Armored Infantry. A counterattack had put the town in German hands once more. As the company halted to get the situation from the tankers, the Germans opened up with an artillery barrage. The company spent the night in foxholes on the outskirts of the town. Early the next morning orders were received to take the town before daylight. In spite of the confusion caused by the artillery and the fact that the men were scattered, Capt. John R. Ellis Jr. reorganized the company and took the town without the loss of a man.
