Colonel Robert Gould Shaw - 54th Massachusetts. An excellent book and movie was made about the 54th. The name is "Glory"
This was the personal folding mirror of Colonel Robert Gould Shaw from the 54th Massachusetts Infantry (Glory). It was part of his personal belongings left in his tent after the attack on Battery Wagner. The number "2" is when he was with the 2nd Massachusetts Infantry. More details are in my recent book "The Civil War Soldier - His Personal Items". R. Jones collection.
On Boston Common, at the corner of Beacon and Park streets, stands what many consider to be the greatest public sculpture in the United States. The high-relief bronze memorial (detail shown) created by sculptor Augustus Saint-Gaudens honors Colonel Robert Gould Shaw and the African American soldiers of the 54th Massachusetts Regiment. It took Saint-Gaudens almost 14 years to complete his tribute.
