The President of the United States of America, authorized by Act of Congress July 9, 1918, takes pleasure in presenting the Distinguished Service Cross to Second Lieutenant (Armor) Karl H. Timmermann (ASN: 0-1311343), United States Army, for extraordinary heroism in connection with military operations against an armed enemy while serving with Company A, 27th Armored Infantry Battalion, 9th Armored Division, in action against enemy forces in Germany, on 7 March 1945. Upon reaching the Ludendorff railroad bridge across the Rhine River, Second Lieutenant Timmermann, aware that the bridge was prepared for demolition, and in the face of heavy machine gun, small arms and direct 20-mm. gun fire, began a hazardous trip across the span. Although artillery shells and two explosions rocket the bridge, he continued his advance. Upon reaching the bridge towers on the far side, he cleared them of snipers and demolition crews. Still braving the intense machine gun and shell fire, he reached the eastern side of the river where he eliminated hostile snipers and gun crews from along the bank and on the face of the bluff overlooking the river. By his outstanding heroism and unflinching valor, Second Lieutenant Timmermann contributed materially to the establishment of the first bridgehead across the Rhine River.
