Step-by-step explanation:
The Fifty-Fourth Massachusetts led a valiant assault on Fort Wagner during the American Civil War, which played a significant role in changing the perceptions of many whites regarding the capabilities and valor of African American soldiers. This battle demonstrated their courage and combat abilities, contributing to broader support for the U.S. Colored Troops (USCT). The 54th Massachusetts went on to serve with distinction until the end of the war in April 1865, and their legacy remains a point of pride, as represented by the monument on the Boston Commons and broader recognition in history and popular culture, such as the 1989 film, Glory. African American soldiers fought in over 400 battles and skirmishes, with the 54th Massachusetts' bravery at Fort Wagner being a standout moment that helped cement their legacy and lay their claims for citizenship.
