Niniveh itself lay upon the Tigris between Kalchu and Sargon’s city, just where the Tigris is met by the Choser. Low hills descend from the north upon the very site of the fortress, and then curve east and south, bow-shaped, to draw west again upon the Tigris at the south end of the city. To the east of the latter they leave a level plain, some two and a half miles by one and a half. These hills appear to have been covered by several forts. The city itself was four-sided, lying lengthwise to the Tigris and cut across its breadth by the Choser. The circumference was about seven and a half miles, enclosing the largest fortified space in Western Asia, and capable of holding a population of three hundred thousand. The western wall, rather over two and a half miles long, touched the Tigris at either end, but between there lay a broad, bow-shaped stretch of land, probably in ancient times, as now, free of buildings. The north-western wall ran up from the Tigris for a mile and a quarter to the low ridge which entered the city at its northern corner. From this the eastern wall, with a curve upon it, ran down in face of the eastern plain for a little more than three miles, and was joined to the western by the short southern wall of not quite half a mile. The ruins of the western wall stand from ten to twenty, those of the others from twenty-five to sixty, feet above the natural surface, with here and there the still higher remains of towers. There were several gates, of which the chief were one in the northern and two in the eastern wall. Round all the walls except the western ran moats about a hundred and fifty feet broad—not close up to the foot of the walls, but at a distance of some sixty feet. Water was supplied by the Choser to all the moats south of it; those to the north were fed from a canal which entered the city near its northern corner. At these and other points one can still trace the remains of huge dams, batardeaux and sluices; and the moats might be emptied by opening at either end of the western wall other dams, which kept back the waters from the bed of the Tigris. Beyond its moat, the eastern wall was protected north of the Choser by a large outwork covering its gate, and south of the Choser by another outwork, in shape the segment of a circle, and consisting of a double line of fortification more than five hundred yards long, of which the inner wall was almost as high as the great wall itself, but the outer considerably lower. Again, in front of this and in face of the eastern plain was a third line of fortification, consisting of a low inner wall and a colossal outer wall still rising to a height of fifty feet, with a moat one hundred and fifty feet broad between them. On the south this third line was closed by a large fortress.
Upon the trebly fortified city the Medes drew in from east and north, far away from Kalchu and able to avoid even Dur-Sargina. The other fortresses on the frontier and the approaches fell into their hands, says Nahum, like ripe fruit.[258] He cries to Niniveh to prepare for the siege.[259] Military authorities[260] suppose that the Medes directed their main attack upon the northern corner of the city. Here they would be upon a level with its highest point, and would command the waterworks by which most of the moats were fed. Their flank, too, would be protected by the ravines of the Choser. Nahum describes fighting in the suburbs before the assault of the walls, and it was just here, according to some authorities,[261] that the famous suburbs of Niniveh lay, out upon the canal and the road to Khorsabad. All the open fighting which Nahum foresees would take place in these outplaces and broad streets[262]—the mustering of the red ranks,[263] the prancing horses[264] and rattling chariots[265] and cavalry at the charge.[266] Beaten there the Assyrians would retire to the great walls, and the waterworks would fall into the hands of the besiegers. They would not immediately destroy these, but in order to bring their engines and battering-rams against the walls they would have to lay strong dams across the moats; the eastern moat has actually been found filled with rubbish in face of a great breach at the north end of its wall. This breach may have been effected not only by the rams but by directing upon the wall the waters of the canal; or farther south the Choser itself, in its spring floods, may have been confined by the besiegers and swept in upon the sluices which regulate its passage through the eastern wall into the city. To this means tradition has assigned the capture of Niniveh,[267] and Nahum perhaps foresees the possibility of it: the gates of the rivers are opened, the palace is dissolved.[268]
Now of all this probable progress of the siege Nahum, of course, does not give us a narrative, for he is writing upon the eve of it, and probably, as we have seen, in Judah, with only such knowledge of the position and strength of Niniveh as her fame had scattered across the world. The military details, the muster, the fighting in the open, the investment, the assault, he did not need to go to Assyria or to wait for the fall of Niniveh to describe as he has done. Assyria herself (and herein lies much of the pathos of the poem) had made all Western Asia familiar with their horrors for the last two centuries. As we learn from the prophets and now still more from herself, Assyria was the great Besieger of Men. It is siege, siege, siege, which Amos, Hosea and Isaiah tell their people they shall feel: siege and blockade, and that right round the land! It is siege, irresistible and full of cruelty, which Assyria records as her own glory. Miles of sculpture are covered with masses of troops marching upon some Syrian or Median fortress. Scaling ladders and enormous engines are pushed forward to the walls under cover of a shower of arrows. There are assaults and breaches, panic-stricken and suppliant defenders. Streets and places are strewn with corpses, men are impaled, women led away weeping, children dashed against the stones. The Jews had seen, had felt these horrors for a hundred years, and it is out of their experience of them that Nahum weaves his exultant predictions. The Besieger of the world is at last besieged; every cruelty he has inflicted upon men is now to be turned upon himself. Again and again does Nahum return to the vivid details,—he hears the very whips crack beneath the walls, and the rattle of the leaping chariots; the end is slaughter, dispersion and a dead waste.[269]
Two other points remain to be emphasised.
There is a striking absence from both chapters of any reference to Israel.[270] Jehovah of Hosts is mentioned twice in the same formula,[271] but otherwise the author does not obtrude his nationality. It is not in Judah’s name he exults, but in that of all the peoples of Western Asia. Niniveh has sold peoples by her harlotries and races by her witchcraft; it is peoples that shall gaze upon her nakedness and kingdoms upon her shame. Nahum gives voice to no national passions, but to the outraged conscience of mankind. We see here another proof, not only of the large, human heart of prophecy, but of that which in the introduction to these Twelve Prophets we ventured to assign as one of its causes. By crushing all peoples to a common level of despair, by the universal pity which her cruelties excited, Assyria contributed to the development in Israel of the idea of a common humanity.[272]
The other thing to be noticed is Nahum’s feeling of the incoherence and mercenariness of the vast population of Niniveh. Niniveh’s command of the world had turned her into a great trading power. Under Assurbanipal the lines of ancient commerce had been diverted so as to pass through her. The immediate result was an enormous increase of population, such as the world had never before seen within the limits of one city. But this had come out of all races and was held together only by the greed of gain. What had once been a firm and vigorous nation of warriors, irresistible in their united impact upon the world, was now a loose aggregate of many peoples, without patriotism, discipline or sense of honour. Nahum likens it to a reservoir of waters,[273] which as soon as it is breached must scatter, and leave the city bare. The Second Isaiah said the same of Babylon, to which the bulk of Niniveh’s mercenary populace must have fled:—
Thus are they grown to thee, they who did weary thee,
Traders of thine from thy youth up;
Each as he could escape have they fled;
