Here are two videos discussing the Robert Gould Shaw Memorial in the National Gallery of Art. To me it should be the 54th Massachusetts Memorial.

The memorial honors Robert Gould Shaw and the 54th Massachusetts Volunteer Infantry, one of the Civil War’s first black units. The museum exhibit, ‘Tell It with Pride,’ looks at the soldiers of the 54th and the people who recruited the regiment, and includes photographs, documents, and artifacts from the time. “
Here’s the first video:
