Marrin relates the gripping story of how the Yanks "came over" to aid the European Allies and turn the tide in the first Great War. How the United States mobilized industry, trained doughboy soldiers, and promoted the war at home makes for fascinating reading in one of the few books on this topic for young adults. The human cost of the war is poignantly related in tales of the action at Chateau Thierry and Belleau Woods, in the air with the daring men of the Army Air Corps, and with the Lost Battalion at the Battle of Meuse-Argonne. From the sinking of the Lusitania to Armistice Day, Marrin tells the heartrending and inspiring story of the "war to end all wars." Illustrated with maps and photographs.
