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 First Lieutenant (Corps of Engineers) Frederick DeVeber Sill, United States Army, for extraordinary heroism in action while serving with 105th Engineers, 30th Division, American Expeditionary Forces, near Panchaux and Geneve, France, 8 October 1918. Lieutenant Sill performed the difficult task of laying the tape for the jumping-off line and also for the support line on the night preceding the attack of October 8. Despite the fact that one battalion bad changed its line on the 7th and that he had to face a continuous fire of artillery, trench mortars, and machine-guns, he performed a mission which would have been extremely difficult even under normal conditions. While returning to headquarters, Lieutenant Sill carried his wounded orderly through a heavy barrage of machine-gun and artillery fire until assistance could be procured.
