In what ways were the roles of african american men significantly different from women before the civil war?

When conquerors sacked a city and made their conquest, they killed those who fought (disproportionately these were men) and enslaved those who didn't fight (disproportionately these were women). although in war situations, women have fought tooth and nail when it comes to the last line of defenses to protect the children but also have poisoned their children and committed suicide to escape the hell of enslavement.

before the civil war and ensuing emancipation proclamation, the slave man is disposable but the slave woman, not so, because they are the birthing factories of more slaves and will be taken care of accordingly whereas men were beasts of labor. and this is true of any slave society, all the way from ancient greeks to ancient romans to colonial campaigns to the united states.
