By this time Carter and Pickman had divided the ghouls into three parties, one to meet each of the two invading columns and one to remain in the town. The first two at once scrambled up the rocks in their respective directions, while the third was subdivided into a land party and a sea party. The sea party, commanded by Carter, boarded the anchored galley and rowed out to meet the under-manned galley of the newcomers; whereat the latter retreated through the strait to the open sea. Carter did not at once pursue it, for he knew he might be needed more acutely near the town.
Meanwhile the frightful detachments of the moonbeasts and almost-humans had lumbered up to the top of the headlands and were shockingly silhouetted on either side against the grey twilight sky. The thin hellish flutes of the invaders had now begun to whine, and the general effect of those hybrid, half-amorphous processions was as nauseating as the actual odour given off by the toadlike lunar blasphemies. Then the two parties of the ghouls swarmed into sight and joined the silhouetted panorama. Javelins began to fly from both sides, and the swelling meeps of the ghouls and the bestial howls of the almost-humans gradually joined the hellish whine of the flutes to form a frantick and indescribable chaos of daemon cacophony. Now and then bodies fell from the narrow ridges of the headlands into the sea outside or the harbour inside, in the latter case being sucked quickly under by certain submarine lurkers whose presence was indicated only by prodigious bubbles.
For half an hour this dual battle raged in the sky, till upon the west cliff the invaders were completely annihilated. On the east cliff, however, where the leader of the moonbeast party appeared to be present, the ghouls had not fared so well; and were slowly retreating to the slopes of the pinnacle proper. Pickman had quickly ordered reinforcements for this front from the party in the town, and these had helped greatly in the earlier stages of the combat. Then, when the western battle was over, the victorious survivors hastened across to the aid of their hard-pressed fellows; turning the tide and forcing the invaders back again along the narrow ridge of the headland. The almost-humans were by this time all slain, but the last of the toadlike horrors fought desperately with the great spears clutched in their powerful and disgusting paws. The time for javelins was now nearly past, and the fight became a hand-to-hand contest of what few spearmen could meet upon that narrow ridge.
As fury and recklessness increased, the number falling into the sea became very great. Those striking the harbour met nameless extinction from the unseen bubblers, but of those striking the open sea some were able to swim to the foot of the cliffs and land on tidal rocks, while the hovering galley of the enemy rescued several moonbeasts. The cliffs were unscalable except where the monsters had debarked, so that none of the ghouls on the rocks could rejoin their battle-line. Some were killed by javelins from the hostile galley or from the moonbeasts above, but a few survived to be rescued. When the security of the land parties seemed assured, Carter's galley sallied forth between the headlands and drove the hostile ship far out to sea; pausing to rescue such ghouls as were on the rocks or still swimming in the ocean. Several moonbeasts washed on rocks or reefs were speedily put out of the way.
Finally, the moonbeast galley being safely in the distance and the invading land army concentrated in one place, Carter landed a considerable force on the eastern headland in the enemy's rear; after which the fight was short-lived indeed. Attacked from both sides, the noisome flounderers were rapidly cut to pieces or pushed into the sea, till by evening the ghoulish chiefs agreed that the island was again clear of them. The hostile galley, meanwhile, had disappeared; and it was decided that the evil jagged rock had better be evacuated before any overwhelming horde of lunar horrors might be assembled and brought against the victors.
So by night Pickman and Carter assembled all the ghouls and counted them with care, finding that over a fourth had been lost in the day's battles. The wounded were placed on bunks in the galley, for Pickman always discouraged the old ghoulish custom of killing and eating one's own wounded, and the able-bodied troops were assigned to the oars or to such other places as they might most usefully fill. Under the low phosphorescent clouds of night the galley sailed, and Carter was not sorry to be departing from the island of unwholesome secrets, whose lightless domed hall with its bottomless well and repellent bronze door lingered restlessly in his fancy. Dawn found the ship in sight of Sarkomand's ruined quays of basalt, where a few night-gaunt sentries still waited, squatting like black horned gargoyles on the broken columns and crumbling sphinxes of that fearful city which lived and died before the years of man.
The ghouls made camp amongst the fallen stones of Sarkomand, despatching a messenger for enough night-gaunts to serve them as steeds. Pickman and the other chiefs were effusive in their gratitude for the aid Carter had lent them. Carter now began to feel that his plans were indeed maturing well, and that he would be able to command the help of these fearsome allies not only in quitting this part of dreamland, but in pursuing his ultimate quest for the gods atop unknown Kadath, and the marvellous sunset city they so strangely withheld from his slumbers. Accordingly he spoke of these things to the ghoulish leaders; telling what he knew of the cold waste wherein Kadath stands and of the monstrous Shantaks and the mountains carven into double-headed images which guard it. He spoke of the fear of Shantaks for night-gaunts, and of how the vast hippocephalic birds fly screaming from the black burrows high up on the gaunt grey peaks that divide Inquanok from hateful Leng. He spoke, too, of the things he had learned concerning night-gaunts from the frescoes in the windowless monastery of the High-Priest Not To Be Described; how even the Great Ones fear them, and how their ruler is not the crawling chaos Nyarlathotep at all, but hoary and immemorial Nodens, Lord of the Great Abyss.
All these things Carter glibbered to the assembled ghouls, and presently outlined that request which he had in mind and which he did not think extravagant considering the services he had so lately rendered the rubbery doglike lopers. He wished very much, he said, for the services of enough night-gaunts to bear him safely through the aft past the realm of Shantaks and carven mountains, and up into the old waste beyond the returning tracks of any other mortal. He desired to fly to the onyx castle atop unknown Kadath in the cold waste to plead with the Great Ones for the sunset city they denied him, and felt sure that the night-gaunts could take him thither without trouble; high above the perils of the plain, and over the hideous double heads of those carven sentinel mountains that squat eternally in the grey dusk. For the horned and faceless creatures there could be no danger from aught of earth since the Great Ones themselves dread them. And even were unexpected things to come from the Other Gods, who are prone to oversee the affairs of earth's milder gods, the night-gaunts need not fear; for the outer hells are indifferent matters to such silent and slippery flyers as own not Nyarlathotep for their master, but bow only to potent and archaic Nodens.
A flock of ten or fifteen night-gaunts, Carter glibbered, would surely be enough to keep any combination of Shantaks at a distance, though perhaps it might be well to have some ghouls in the party to manage the creatures, their ways being better known to their ghoulish allies than to men. The party could land him at some convenient point within whatever walls that fabulous onyx citadel might have, waiting in the shadows for his return or his signal whilst he ventured inside the castle to give prayer to the gods of earth. If any ghouls chose to escort him into the throne-room of the Great Ones, he would be thankful, for their presence would add weight and importance to his plea. He would not, however, insist upon this but merely wished transportation to and from the castle atop unknown Kadath; the final journey being either to the marvellous sunset city itself, in case of gods proved favourable, or back to the earthward Gate of Deeper Slumber in the Enchanted Wood in case his prayers were fruitless.
