Explanation: During the US Civil War, Union General Ulysses S. Grant generously offered to allow surrendering Confederate traitors to keep their sidearms and clothing, and simply be 'paroled', in exchange for giving up the vital stronghold of Vicksburg. Confederate General Pemberton counter-offered that they should be allowed to keep their 'personal property' in general when they left Vicksburg, as a gesture of good faith.
Grant, realizing full goddamn well that was an excuse for the Confederates to drag enslaved people along with them, as the Confederates regarded slaves as 'personal property', refused, and said that if the terms offered by the Union were unacceptable, hostilities would resume by morning.
Pemberton surrendered under Grant's offered terms.
