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 First Class Joseph F. Sullivan (ASN: 2804), United States Army, for extraordinary heroism in action while serving with Medical Detachment, 101st Infantry Regiment (Attached), 26th Division, American Expeditionary Forces, during the Aisne-Marne offensive, France, 23 July 1918. During the advance around Chateau-Thierry, Company B of the regiment to which Private Sullivan was attached became surrounded by the enemy. Their losses were extremely heavy and it appeared as though the entire company would be wiped out or captured. After several men had been killed in attempting to get through the enemy lines to obtain assistance, Private Sullivan volunteered to make the attempt and succeeded in getting through and bringing assistance to Company H, thus enabling the company to continue its advance.
