Here is the 1921 book review of Three Soldiers by John Dos Passos from CURRENT OPINION:
"It is the novel of a man of genius. The intricate, complex, confused background of the machinery of the war, ceaselessly and brutally in action, snatching up its human material, grinding them out as so many articles of discipline, is epical in its effect upon the imagination. The sense of human foulness typified in the incessant desire of the men under military domination for drink and sensual excitement, would be unbearably sordid if Mr. Dos Pasos' power to balance it with the interweaving of beauty was not so great."
