Massachusetts and Seven Dollars a Month

54th Massachusetts Volunteer Infantry Monument.  Boston Common, Boston, MA.

Refusing their reduced pay became a point of honor for the men of the 54th. In fact, at the Battle of Olustee, when ordered forward to protect the retreat of the Union forces, the men moved forward shouting, “Massachusetts and Seven Dollars a Month!” Unknown to them, Congress had just voted to pay colored troops the same as white troops.
