We had an enormous concentration of artillery and of aviation, thanks to assistance from the French, but our aviation and much of that of the French sent us was new. Our aviators lacked experience as observers in keeping their liaison in directing artillery fire and in informing the infantry of the movements of their units and of the enemy's. Infantry and artillery commanders who had had little previous battle experience, were not always fortunate in their efforts to keep liaison with one another and with the aviation in view of the aviation's inexperience. To say that the American army was ready for such an offensive as that of the Meuse-Argonne would be unfair to the men who began the battle and detracting from the glory of their achievement. Her courage, eagerness, adaptability, and industry were merits which were to overcome the handicaps in a way that made results even more glorious in the greatest battle of our history. Aside from the fact that two of the divisions in line were going under fire for the first time there was not one of the divisions which was not handicapped in some way for their effort, either for want of artillery or because they had had no time to rest after hard marches or previous battles. In the space of this brief review it is impossible to tell of their actions in detail which reflected credit on each one of the Regular, National Guard, or National Army divisions, and which, taken together, reflected credit upon the army as a whole. On the right was Bell's 33d Division of Illinois National Guard. At its back was the famous _Mort Homme_, or Dead Man's Hill, where Frenchmen and Germans had struggled in the battle of Verdun, with its shell craters now fringed with weeds. The 33d had to cross the Forges Brook and swing in toward the Meuse River protecting the right flank of the whole movement which rested on the river. On the left of the 33d was the 80th, Cronkhite's Blue Ridge Division, trained at the British front and come from Saint Mihiel. Next in line was the 4th Regular Division, which, coming fresh from the British front, had fought magnificently in the Château-Thierry operations. On its left was Kuhn's 79th, the National Army Division from Camp Meade, which had never heard a shot fired until it marched up amidst the roar of guns and artillery preparation. Then we had Farnsworth's 37th, National Guard of Ohio, which with unconquerable persistence was to take the wicked Malancourt Woods; and then the 91st Division of the National Army from the Pacific slope which was to give such a remarkable exhibition of continued and determined advance. Next we had Traub's 85th Division, National Guard from Kansas and Missouri, which was set the dreadful task of taking the heights on the west of the Aire river and of crossing the Exermont ravine. Next was Muir's 28th, or "Iron" Division, National Guard of Pennsylvania, which was in the valley of the Aire and faced the wooded heights of the Argonne which were thrust
