The President of the United States of America, authorized by Act of Congress, July 9, 1918, takes pleasure in presenting a Bronze Oak Leaf Cluster in lieu of a Second Award of the Distinguished Service Cross to First Lieutenant (Medical Corps) Frank L. Williams, United States Army, for extraordinary heroism in action while serving with 168th Infantry Regiment (Attached), 42d Division, American Expeditionary Forces, near Chateau-Thierry, France, 29 July 1918. Lieutenant Williams went forward with his battalion and cared for the wounded under difficult circumstances. He was without shelter, food, and sleep for practically three days. The area over which he worked was constantly swept with artillery and machine-gun fire and was drenched with poisonous gas. He was always close behind his battalion with his aid post, the selection of its location being at all times for the benefit of the wounded and not as a matter of personal safety. Much of his work was at night, where enemy observation and absence of suitable cover made it impossible to use lights of any kind, but taxing himself to his fullest powers of strength, endurance, and skill he dressed the wounded in darkness by sense of touch alone. Although given permission and advised to withdraw farther to the rear and to a less exposed position, he expressed his desire to remain in the forward lines in order to give his services as soon as possible to the wounded men.
