Paraphrase

This is an excerpt taken from an article on the Civil War movie "Glory","The decision to end the movie with the failed assault at Wagner solidifies this progressive theme, which links the men to one another and, supposedly, the goal of the United States by the middle of the war. The final scenes depict the grim reality of the battlefield, including shoe-less dead black soldiers, and a mass grave in which both Shaw and his men are buried. As the movie ends the viewer is told that the performance of the 54th Massachusetts led to the recruitment of upwards of 180,000 men and that President Lincoln credited these men with turning the tide of war."

After reading this article, I found some interesting information on the movie Glory and the Civil War.
The choice to end Glory with an unsuccessful attempt to break Wagner strengthens this theme, this brings the men closer together and, apparently, the goal of the United States by the the time the war was half over. The ending scenes show the gruesome slaughter of the field of battle, including black soldiers with nothing on their feet, and no individual graves, but piles of bodies in a hole, including Shaw and his soldiers. In the ending scene viewers are told that unit of men indirectly lead to 180,000 men signing up for the union and also President Lincoln saying that these men changed the fate of the war for the Union
