Which was NOT a role of African Americans in the army

the  seven  days  battles  were  a series of seven battles over seven  days from june 25 to july 1, 1862, near richmond, virginia,  during  the american civil war. the  seven  days ended with mcclellan's army in relative safety next to the james river, having suffered almost 16,000 casualtiesduring  the retreat.

i actually think that the correct answer is: the roman senate power's could not exercise complete control over the common people or plebeians.

.hope that . and can i get brainest point
