Khossuth suggested that we lie in wait among the trees along the bank, and pick the watchers off at long range at dawn, but this I knew to be impossible. There was no cover along the water's edge, and the river lay between. The men in the tower were out of our range. We might creep near enough to pick off one or two, but it was imperative that all should perish, since the escape of one would be enough to ruin our plans.
So we stole through the woods until we reached a point a mile upstream, opposite a jutting tongue of rock, toward which, I believed, a current set in from the center of the stream. There we placed in the water a heavy, strong catamaran we had constructed, with a long powerful rope. I got upon the craft with four of the best marksmen of the combined horde-Thab the Swift, Skel the Hawk, and two warriors of Khor. Each of us bore two carbines, strapped to our backs.
We bent to work with crude oars, though our efforts seemed ludicrously futile in the teeth of that flood. But the raft was long enough and heavy enough not to be spun by every whirlpool we crossed, and by dint of herculean effort we worked out toward the middle of the stream. The men on shore paid out the rope, and it acted as a sort of brace, swinging us around in a wide arc that would have eventually brought us back to the bank we had left, had not the current we hoped for suddenly caught us and hurled us at dizzy speed toward the projecting tongue of rock. The raft reeled and pitched, driving its nose under repeatedly, until sometimes we were fully submerged. But our ammunition was waterproof, and we had lashed ourselves to the logs; so we hung on like drowned rats, until our craft was dashed against the rocky point.
It hung there for a breathless instant, in which time it was touch and go. We slashed ourselves loose, jumped into the water which swirled arm-pit deep about us, and fought our way along the point, clinging tooth and nail to every niche or projection, while the foaming current threatened momentarily to tear us away and send us after our raft which had slid off the ledge and was dancing away down the river.
We did make it, though, and hauled ourselves upon the shore at last, half dead from buffeting and exhaustion. But we could not stop to rest, for the most delicate part of our scheme was before us. It was necessary that we should not be discovered before dawn gave us light enough to see the sights of our carbines, for the best marksman in the world is erratic by starlight. But I trusted to the chance that the Yagas would be watching the river, and paying scant heed to the desert behind them.
So in the darkness that precedes dawn, we stole around in a wide-circle, and the first hint of light found us lying in a depression we had scraped in the sand not over four hundred yards to the south of the tower.
It was tense waiting, while the dawn lifted slowly over the land, and objects became more and more distinct. The roar of the water over the Bridge of Rocks reached us plainly, and at last we were aware of another sound. The clash of steel reached us faintly through the water tumult. Ghor and others were advancing to the river bank, according to my instructions. We could not see any Yagas on the tower; only hints of movement along the turrets. But suddenly one whirled up into the morning sky and started south at head-long speed. Skel's carbine cracked and the winged man, with a loud cry, pitched sideways and tumbled to earth.
There followed an instant of silence; then five winged shapes darted into the air, soaring high. The Yagas sensed what was occurring, and were chancing all on a desperate rush, hoping that at least one might get through. We all fired, but I scored a complete miss, and Thab only slightly wounded his man. But the others brought down the man I had missed, while Thab's second shot dropped the wounded Yaga. We reloaded hastily, but no more came from the tower. Six men watched there, Yasmeena had said. She had spoken the truth.
We cast the bodies into the river. I crossed the Bridge of Rocks , leaping from boulder to boulder, and told Ghor to take his men back into the forest, and to bring up the host. They were to camp just within the fringe of woods, out of sight from the sky. I did not intend to start across the desert until nightfall.
Then I returned to the tower and attempted to gain entrance, but found no doors, only a few small barred windows. The Yagas had entered it from the top. It was too tall and smooth to be climbed, so we did the only thing left to do. We dug pits in the sand and covered them with branches, over which we scattered dust. In these pits we concealed our best marksmen, who lay all day, patiently scanning the sky. Only one Yaga came winging across the desert. No human was in sight, and he was not suspicious until he poised directly over the tower. Then, when he saw no watchmen, he became alarmed, but before he could race away, the reports of half a dozen carbines brought him tumbling to the earth in a whirl of limbs and wings.
As the sun sank, we brought the warriors across the Bridge of Rocks , an accomplishment which required some time. But at last they all stood on the Yaga side of the river, and with our canteens well filled, we started at quick pace across the narrow desert. Before dawn we were within striking distance of the river.
Having crossed the desert under cover of darkness, I was not surprised that we were able to approach the river without being discovered. If any had been watching from the citadel, alert for anything suspicious, they would have discerned our dark mass moving across the sands under the dim starlight. But I knew that in Yugga no such watch was ever kept, secure as the winged people felt in the protection of the Purple River, of the watchmen in the tower, and of the fact that for centuries no Gura raid had dared the bloody doom of former invaders. Nights were spent in frenzied debauchery, followed by sodden sleep. As for the men of Akka, these slow-witted drudges were too habitually drowsy to constitute much menace against our approach, though I knew that once roused they would fight like animals.
So three hundred yards from the river we halted, and eight thousand men under Khossuth took cover in the irrigation ditches that traversed the fields of fruit. The waving fronds of the squat trees likewise aided in their concealment. This was done in almost complete silence. Far above us towered the somber rock Yuthla. A faint breeze sprang up, forerunner of dawn. I led the remaining thousand warriors toward the river bank. Halting them a short distance from it, I wriggled forward on my belly until my hands were at the water's edge. I thanked the Fates that had given me such men to lead. Where civilized men would have floundered and blundered, the Guras moved as easily and noiselessly as stalking panthers.
Across from me rose the wall, sheer from the steep bank, that guarded Akka. It would be hard to climb in the teeth of spears. At the first crack of dawn, the bridge, which towered gauntly against the stars, would be lowered so that Akkis might go into the fields to work. But before then the rising light would betray our forces.
With a word to Ghor, who lay at my side, I slid into the water and struck out for the farther shore, he following. Reaching a point directly below the bridge, we hung in the water, clutching the slippery wall, and looked about for some way of climbing it. There the water, near the bank, was almost as deep as in midstream. At last Ghor found a crevice in the masonry, wide enough to give him a grip for his hands. Then bracing himself, he held fast while I clambered on his shoulders. Standing thus I managed to reach the lower part of the lifted bridge, and an instant later I drew myself up. The erected bridge closed the gap in the wall. I had to clamber over the barrier. One leg was across, when a figure sprang out of the shadows, yelling a warning. The watchman had not been as drowsy as I had expected.
He leaped at me, the starlight glinting on his spear. With a desperate twist of my body, I avoided the whistling blade, though the effort almost toppled me from the wall. My out-thrown hand gripped his lank hair as he fell against the coping with the fury of his wasted thrust, and jerking myself back into balance, I dealt him a crushing buffet on the ear with my clenched fist. He crumpled, and the next instant I was over the wall.
