All night long the gathering of that sinister synod continued. All night long those furtive forces moved through the forest. They passed by every road, by every lane, through every avenue of trees. I heard the whispered commands of the officers. I heard the sloshing of the mud under foot and the occasional muffled curse of some weary marcher who would slip to the ground under the weight of his burden; and I knew, all of us knew, that at the zero hour, 4:35 o'clock in the morning, all hell would land on the German line, and these men from the trees would move forward with the fate of the world in their hands. There was some suspense. We knew that if the Germans had had the slightest advance knowledge about that mobilisation of Foch's reserves that night, they would have responded with a downpour of gas shells, which spreading their poisonous fumes under the wet roof of the forest, might have spelt slaughter for 70,000 men. But the enemy never knew. They never even suspected. And at the tick of 4:35 A. M., the heavens seemed to crash asunder, as tons and tons of hot metal sailed over the forest, bound for the German line. That mighty artillery eruption came from a concentration of all the guns of all calibres of all the Allies that Foch could muster. It was a withering blast and where it landed in that edge of the forest occupied by the Germans, the quiet of the dripping black night was suddenly turned into a roaring inferno of death. Giant tree trunks were blown high into the air and splintered into match-wood. Heavy projectiles bearing delayed action fuses, penetrated the ground to great depth before exploding and then, with the expansion of their powerful gases, crushed the enemy dugouts as if they were egg shells. Then young America--your sons and your brothers and your husbands, shoulder to shoulder with the French--went over the top to victory. The preliminary barrage moved forward crashing the forest down about it. Behind it went the tanks ambling awkwardly but irresistibly over all obstructions. Those Germans that had not been killed in the first terrific blast, came up out of their holes only to face French and American bayonets, and the "Kamerad" chorus began at once. Our assaulting waves moved forward, never hesitating, never faltering. Ahead of them were the tanks giving special attention to enemy machine gun nests that manifested stubbornness. We did not have to charge those death-dealing nests that morning as we did in the Bois de Belleau. The tanks were there to take care of them. One of these would move toward a nest, flirt around it several minutes and then politely sit on it. It would never be heard from thereafter.
