Though completely loyal to the Revolution, Martha is a more quiet supporter of the cause.  She's not entirely okay with violence and death, but she tries to go by.  During the Revolutionary War, Martha becomes haunted with her duel and the fact that she nearly killed someone.  Even with her dreams of leading a fully-black battalion coming true, she never supported the war entirely, even in death.  She's a great friend of the two Elizabeths, but she seemed to have a closer relationship with Adrienne (in a Laurens/Hamilton kinda of way).
