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 Private Ralph B. Sullivan (ASN: 1217078), United States Army, for extraordinary heroism in action while serving with Battery B, 104th Field Artillery, 27th Division, American Expeditionary Forces, near Montzeville, France, 14 September 1918. When a continuous bombardment had set fire to the camouflage covering of a large ammunition dump of 75-mm. shells and exploded nine of the shells, Private Sullivan utterly disregarding his personal safety left a sheltered position and ran to the dump, and, with the aid of three other men, extinguished the fire, not only saving the ammunition but also preventing the ascertainment of the exact location of the dump by the enemy.
