describe the tattered soldier based on the dialogue he has in this chapter?why is dialogue an effective style device for crane to use

Henry still remains speechless, unable to act as this chapter opens. His companion, the tattered soldier, speaks as much as anyone in this book has up to this point. The chapter is dominated with his words. He can speak easily and freely. Because of his wounds, he feels woozy and strange; and he rambles throughout the chapter. The tattered man, however, feels that the youth is wounded and yet does not know it. He calls after him, in his confused way, to stop and not go. "It ain't right," he says, for Henry to just walk away. Yet Henry must. He does not belong to these people, who bring "ghosts of shame" into his mind. Furthermore, these men, though they have red badges of courage, are near to death. This fact dominates the scene.
