There now was no thought of safety in the hearts of the Aerians. They had come forth to kill and be killed. The rules of aerial tactics were utterly neglected. They laid their guns alongside and, rushing through the air at their utmost speed, they hurled themselves with the ram upon every Moslem or Russian vessel that they could meet or overtake, crashing into her with irresistible force and going with her into annihilation as their two cargoes of shells exploded under the shock.
The last sun rose and saw the fight still going on. What had begun as the greatest battle in the history of war had now dwindled down to a series of single combats. At length the end came. It was a few minutes after midday that the last blow in the battle was struck. Ten Russian and Moslem air-ships, all that remained of the great fleet that Olga had brought against Aeria, formed in line ten miles from the Ridge and made a last attempt to break through the defences.
Flying through a storm of shells from the land batteries, seven of them were torn to pieces and the other three, just as they reached the Ridge, were met obliquely by the five remaining vessels of the Aerian fleet. The same moment the Alma’s broadside was discharged upon them, friend and foe vanished together in a mist of flame—and so ended the assault and defence of Aeria.
“We can go down now!” said Alan in a broken voice to Alma, who was standing white and speechless with horror at his side in the bows of the air-ship. “It is all over! God rest their gallant souls, for they left the world like brave men and true Aerians!”
“Amen!” sighed Alma. Then, after a brief pause, she said—“I wonder whether Olga Romanoff is alive or dead?”
The two air-ships now sank together and alighted close to the entrance to the caverns.
There the splendid fabrics were reluctantly abandoned, their crews disembarked, taking with them everything they wished to preserve, and a minute inspection was made for the last time of the triple doors and the machinery for lowering them and filling the spaces between them with water to be frozen as soon as they were in their places.
This occupied the time until the evening, and then all went once more into the open air to take what might be their last look at the sun. The waters of the lake were now within a few feet of the entrance, creeping more and more slowly upwards, and across the vast expanse of water, lying unruffled by the lightest breeze, fell the mingled rays of the sinking sun and the brightening Fire-Cloud.
There was not a cloud in the heavens and no breath of wind relieved the almost suffocating heat of the inert and sultry air. It seemed as though all terrestrial nature lay paralysed in a stupor of terror, waiting for the fire-blast that would wither it into death and ruin.
As the sun sank down behind the veil of flame his disc loomed redly and dully through it. Long streams of fire, blue and green and orange, darted across the disc and leapt and played round its circumference until it sank finally out of sight. The little group on the shore of the lake gazed at each other in silence as it disappeared.
