I have a book , 98 pages with excellent photos of Union and Confederate Drummer Boys. It is called "When Johnny Went Marching", "young Americans Fight the Civil War", by G. Clifton Wisler, First Edition 2001, HarperCollins Publishers.
Wisler shows a famous picture of a young African American boy, who is only named "Drummer Jackson" and was believed to have been with the "1st kansas Colored Infantry Regiment, a unit formed of escaped slaves and free blacks." On April 18,1864, the regiment fought a defiant battle against overwhelming Confederate forces to save a Union supply train after other units had run. They suffered major casualties wounded and dead, even after some had surrendered to the Confederates. This was added to the "Give no Quarter" ,list.
Fifteen year old, five foot tall Charles Miles Moore, an African American, of Elmira, New York, who was a coachman, left Elmira and journeyed all the way to Massachusetts to join the 54th Massachusetts Regiment and managed to talk his way into the muster roll as a drummer for co. H and saw action at James Island and at Fort Wagner, the scene of the motion picture, "Glory".
