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 First Lieutenant (Air Service) Jacques Michael Swaab, United States Army Air Service, for extraordinary heroism in action while serving with 22d Aero Squadron, 2d Pursuit Group, U.S. Army Air Service, A.E.F., near Montfaucon, France, 28 September 1918, and in the region of Champignuelle, 27 October 1918. On September 28 Lieutenant Swaab, although himself pursued by two enemy planes, perceiving one of his comrades in distress and in danger of being shot down, dived upon the enemy plane which was directly behind that of his comrade and shot the enemy plane out of control, forcing it to withdraw. His prompt act in going to the assistance of his comrade enabled the latter to escape. On October 27 Lieutenant Swaab and another member of his group engaged in combat with seven enemy planes. In this encounter, although outnumbered, Lieutenant Swaab continued in his attack and succeeded in shooting down an enemy D. F. W. observation plane.
