The President of the United States of America takes pleasure in presenting the Navy Cross to Lieutenant (MC) Frederick R. Hook, United States Navy, for extraordinary heroism while serving as Assistant Surgeon with the Fifth Regiment (Marines), 2d Division, American Expeditionary Forces in action on the French front. During the attack on the Bois de Belleau and at Blanc Mont Lieutenant Hook showed exceptional heroism and devotion to duty in caring for the wounded under fire. At Blanc Mont he established advanced dressing stations and maintained them as close to the front line as possible. He was constantly exposed to heavy shell and machine-gun fire and showed entire disregard for personal safety.
