Responding to President Wilson's request to congress on April 2nd, 1917, the U.S. entered WWI.
Becoming known by the nickname "doughboy," thousands of U.S. infantrymen joined the Allies in the trenches of France after the U.S. declaration of war on April 6, 1917. It was a dismal situation for both sides, escalated artillery bombarments preceding an attacker's rushing assault. Such was the plight of infantryman Pillsbury, the only survivor of direct artillery hits in his section of trench when the German infantry came rushing at him.
Pillsbury didn't hesitate, firing his rifle so fast the oncoming Germans thought the pops from his rifle were those of a machine gun. Pillsbury kept shooting, only momentarily halting to reload, then he opened up again, his barrel quickly heating like a sizzling tube, piping hot; the Pillsbury doughboy was popping good.
