 So, if I had to pick one image to represent the revolutionary changes of the Civil War, it would probably be this one. It's from a photograph taken by William Morris Smith in 1865. This is a detail from that photograph. It's the men of Company E of the 4th United States Colored Infantry at Fort Lincoln, which is in Washington, D.C. The detail shows the emotions and individuality of these figures. One of them even has a wedding band on. This is part of the revolutionary changes of the war for these former slaves. But there's a detail here that makes this photograph even more interesting. This photograph was taken on November 17th, 1865. And when you realize that the photograph was taken after the war was over, then the anxiety, the defiance, the anger you see on some of their faces takes on a whole new meaning. These men aren't thinking about combat. They're thinking about freedom. And of course, that's why this is a great gateway into the Civil War. The war did many things. It saved the Union. It abolished slavery. But it did not answer all the questions about liberty and equality that, you know, still in so many ways consume us today.
