Will you suffer your soldier, captured in fighting your battles, to be in confinement for months rather than release him by giving for him that which you call a piece of property, and which we are willing to accept as a man? You certainly appear to place less value upon your soldier than you do upon your negro. I assure you, much as we of the North are accused of loving property, our citizens would have no difficulty in yielding up any piece of property they have in exchange for one of their brothers or sons languishing in your prisons.

As quoted in Autobiography and Personal Reminiscences of Major-General Benj. F. Butler (1892), pp. 604–605
