Seeking only escape from man, the Mahars left their new home and moved back a short distance toward The Empire, but now their enemies seemed bent only upon persecution; they hunted them, and when they found them the Mahars were again forced to fall back before the ferocity of their continued attacks.
Eventually they took refuge within the boundaries of The Empire, and scarcely had David's expedition to them returned with its report when we had definite proof of the veracity of their tale through messages from our northernmost frontier bearing stories of invasion by a strange, savage race of white men. Frantic was the message from Goork, King of Thuria, whose far-flung frontier stretches beyond the Land of Awful Shadow .
Some of his hunters had been surprised and all but a few killed or captured by the invaders.
He had sent warriors, then, against them, but these, too, had met a like fate, being greatly outnumbered, and so he sent a runner to David begging the Emperor to rush troops to his aid.
Scarcely had the first runner arrived when another came, bearing tidings of the capture and sack of the principal town of the Kingdom of Thuria; and then a third arrived from the commander of the invaders demanding that David come with tribute or they would destroy his country and slay the prisoners they held as hostages.
In reply David dispatched Tanar, son of Ghak, to demand the release of all prisoners and the departure of the invaders.
Immediately runners were sent to the nearest kingdoms of The Empire and ere Tanar had reached the Land of Awful Shadow , ten thousand warriors were marching along the same trail to enforce the demands of the Emperor and drive the savage foe from Pellucidar.
As David approached the Land of Awful Shadow that lies beneath Pellucidar's mysterious satellite, a great column of smoke was observable in the horizonless distance ahead.
It was not necessary to urge the tireless warriors to greater speed, for all who saw guessed that the invaders had taken another village and put it to the torch.
And then came the refugees—women and children only—and behind them a thin line of warriors striving to hold back swarthy, bearded strangers, armed with strange weapons that resembled ancient harquebuses with bell-shaped muzzles—huge, unwieldy things that belched smoke and flame and stones and bits of metal.
That the Pellucidarians, outnumbered ten to one, were able to hold back their savage foes at all was due to the more modern firearms that David and I had taught them to make and use.
Perhaps half the warriors of Thuria were armed with these and they were all that saved them from absolute rout, and, perhaps, total annihilation.
Loud were the shouts of joy when the first of the refugees discovered and recognized the force that had come to their delivery.
Goork and his people had been wavering in allegiance to The Empire, as were several other distant kingdoms, but I believe that this practical demonstration of the value of the Federation ended their doubts forever and left the people of the Land of Awful Shadow and their king the most loyal subjects that David possessed.
The effect upon the enemy of the appearance of ten thousand well-armed warriors was quickly apparent. They halted, and, as we advanced, they withdrew, but though they retreated they gave us a good fight.
David learned from Goork that Tanar had been retained as a hostage, but though he made several attempts to open negotiations with the enemy for the purpose of exchanging some prisoners that had fallen into our hands, for Tanar and other Pellucidarians, he never was able to do so.
Our forces drove the invaders far beyond the limits of The Empire to the shores of a distant sea, where, with difficulty and the loss of many men, they at last succeeded in embarking their depleted forces on ships that were as archaic in design as were their ancient harquebuses.
These ships rose to exaggerated heights at stern and bow, the sterns being built up in several stories, or housed decks, one atop another. There was much carving in seemingly intricate designs everywhere above the water line and each ship carried at her prow a figurehead painted, like the balance of the ship, in gaudy colors—usually a life size or a heroic figure of a naked woman or a mermaid.
The men themselves were equally bizarre and colorful, wearing gay cloths about their heads, wide sashes of bright colors and huge boots with flapping tops—those that were not half naked and barefoot.
Besides their harquebuses they carried huge pistols and knives stuck in their belts and at their hips were cutlasses. Altogether, with their bushy whiskers and fierce faces, they were at once a bad-looking and a picturesque lot.
From some of the last prisoners he took during the fighting at the seashore, David learned that Tanar was still alive and that the chief of the invaders had determined to take him home with him in the hope that he could learn from Tanar the secrets of our superior weapons and gunpowder, for, notwithstanding my first failures, I had, and not without some pride, finally achieved a gunpowder that would not only burn, but that would ignite with such force as to be quite satisfactory. I am now perfecting a noiseless, smokeless powder, though honesty compels me to confess that my first experiments have not been entirely what I had hoped they might be, the first batch detonated having nearly broken my eardrums and so filled my eyes with smoke that I thought I had been blinded.
When David saw the enemy ships sailing away with Tanar he was sick with grief, for Tanar always has been an especial favorite of the Emperor and his gracious Empress, Dian the Beautiful. He was like a son to them. We had no ships upon this sea and David could not follow with his army; neither, being David, could he abandon the son of his best friend to a savage enemy before he had exhausted every resource at his command in an effort toward rescue.
In addition to the prisoners that had fallen into his hands David had captured one of the small boats that the enemy had used in embarking his forces, and this it was that suggested to David the mad scheme upon which he embarked.
The boat was about sixteen feet long and was equipped with both oars and a sail. It was broad of beam and had every appearance of being staunch and seaworthy, though pitifully small in which to face the dangers of an unknown sea, peopled, as are all the waters of Pellucidar, with huge monsters possessing short tempers and long appetites.
Standing upon the shore, gazing after the diminishing outlines of the departing ships, David reached his decision. Surrounding him were the captains and the kings of the Federated Kingdoms of Pellucidar and behind these ten thousand warriors, leaning upon their arms. To one side the sullen prisoners, heavily guarded, gazed after their departing comrades, with what sensations of hopelessness and envy one may guess.
David turned toward his people. "Those departing ships have borne away Tanar, the son of Ghak, and perhaps a score more of the young men of Pellucidar. It is beyond reason to expect that the enemy ever will bring our comrades back to us, but it is easy to imagine the treatment they will receive at the hands of this savage, bloodthirsty race.
"We may not abandon them while a single avenue of pursuit remains open to us. Here is that avenue." He waved his hand across the broad ocean. "And here the means of traversing it." He pointed to the small boat.
"It would carry scarce twenty men," cried one, who stood near the Emperor.
"It need carry but three," replied David, "for it will sail to rescue, not by force, but by strategy; or perhaps only to locate the stronghold of the enemy, that we may return and lead a sufficient force upon it to overwhelm it."
"I shall go," concluded the Emperor. "Who will accompany me?"
Instantly every man within hearing of his voice, saving the prisoners only, flashed a weapon above his head and pressed forward to offer his services. David smiled.
