The President of the United States of America, authorized by Act of Congress, July 9, 1918, takes pleasure in presenting the Army Distinguished Service Medal to Colonel (Medical Corps) Walter D. McCaw, United States Army, for exceptionally meritorious and distinguished services to the Government of the United States, in a duty of great responsibility during World War I. Colonel McCaw’s counsel and advice in the early stages of the operations of the American Expeditionary Forces were of particular benefit to the effective work of the Medical Department. As Chief Surgeon of the American Expeditionary Forces, in the later operations in the field, he maintained the splendid efficiency of that department at a critical time and solved each new problem presented with wisdom and marked ability.
