The President of the United States of America takes pleasure in presenting the Navy Cross to Second Lieutenant Jacob Harrison Heckman (MCSN: 0-1453), United States Marine Corps, for extraordinary heroism while serving with the 5th Regiment (Marines), 2d Division, A.E.F. in action in the Bois-de-Belleau, France, 25 June 1918. With the assistance of three sergeants, Lieutenant Heckman started out to destroy the final stand of the enemy in the Bois-de-Belleau, an impregnable position, where enemy guns were concealed by rocks and heavy shrubbery. Armed with only a pistol, Lieutenant Heckman rushed the nest which was offering the most violent resistance, and captured one officer and ninety men. Each of his men destroyed a nest and captured two of the enemy at each position. After effecting the complete reduction of the last element, Lieutenant Heckman marched his prisoners in under a severe and harassing fire of the retreating enemy.
