The President of the United States of America takes pleasure in presenting the Navy Cross to Lieutenant Henry Netterville Fallon, United States Navy, for distinguished service in the line of his profession as an Officer of the Watch of the U.S.S. O’BRIEN in an engagement with a submarine on 14 September 1917. The submarine was discovered in the early dawn and Lieutenant Fallon immediately headed for her at full speed, forcing her to submerge and preventing an attack upon the merchant vessels which were under the escort of the O’BRIEN.
