Walt himself never closed his ears against the call to serve in the ranks, if it should come to him. Had he himself been drawn, he might have regarded the circumstance as the intimation of duty; but he was not. Instead he took the risks of small-pox in the infectious wards, as well as that which is incurred by the frequent dressing of gangrened wounds; and he bore the spiritual burden of all the pathetic war-wreckage which drifted into Washington month after weary month. The tension of those days was terrible to him. Devoted to the "Mother of All," the American nation, he loved her sons both North and South with an equal affection, their suffering and destruction wringing his heart. For, mystic as he was, he had all the strong passions of humanity, and felt to the full the agonies of the flesh. On the one side also, his own brother was in the hottest of the fighting throughout these years; while on the other, it is just possible that some young son of his own, known or unknown to him, may have served among the boys in the opposite ranks before the war was over. His Abolitionist friends would sigh, and say the struggle must go on till every slave should be free; but he who valued freedom not less than they, and understood perhaps better what it really means, dissented from them. The first sight of a battlefield made him cry out for peace; and if in the following months he felt the exhilaration which breathed from the simple heroism displayed by the soldiers, he still saw that war is not all heroic, but in time must darken the fairest cause. The terrible burden of its inconceivable extravagance began to weigh upon him like a nightmare. Each new season, with its prospective train of ambulances, its legion of tragedies, bewildered him with its horror; till he angrily denied that the whole population of negroes could be worth so terrific a purchase.[355] It may have been the exaggerated retort to an extremist argument; but indeed it was not for the negroes that the war was being fought; it was not for the powerful but highly coloured manifesto of _Uncle Tom's Cabin_, but for the "Declaration of Independence," and for the Constitution of America. And this both Whitman and Lincoln realised: they knew the negro of the South as the New Englander never knew him, and were firm in demanding for him the rights of a human being; but they knew also that mere abolition would not give him these, nor could it render him capable of the right exercise of American citizenship. * * * * *
