We remained in Thuria only long enough to arrange the treaty with Goork, among the other details of which was his promise to furnish the imperial army with a thousand lidi, or Thurian beasts of burden, and drivers for them. These were to accompany Ghak's army back to Sari by land, while the fleet sailed to the mouth of the great river from which Dian, Juag, and I had been blown.
The voyage was uneventful. We found the river easily, and sailed up it for many miles through as rich and wonderful a plain as I have ever seen. At the head of navigation we disembarked, leaving a sufficient guard for the feluccas, and marched the remaining distance to Sari.
Ghak's army, which was composed of warriors of all the original tribes of the federation, showing how successful had been his efforts to rehabilitate the empire, marched into Sari some time after we arrived. With them were the thousand lidi from Thuria.
At a council of the kings it was decided that we should at once commence the great war against the Mahars, for these haughty reptiles presented the greatest obstacle to human progress within Pellucidar. I laid out a plan of campaign which met with the enthusiastic indorse-ment of the kings. Pursuant to it, I at once despatched fifty lidi to the fleet with orders to fetch fifty cannon to Sari. I also ordered the fleet to proceed at once to Anoroc, where they were to take aboard all the rifles and ammunition that had been completed since their departure, and with a full complement of men to sail along the coast in an attempt to find a passage to the inland sea near which lay the Mahars' buried city of Phutra.
Ja was sure that a large and navigable river connected the sea of Phutra with the Lural Az, and that, barring accident, the fleet would be before Phutra as soon as the land forces were.
At last the great army started upon its march. There were warriors from every one of the federated kingdoms. All were armed either with bow and arrows or muzzle-loaders, for nearly the entire Mezop contingent had been enlisted for this march, only sufficient having been left aboard the feluccas to man them properly. I divided the forces into divisions, regiments, battalions, companies, and even to platoons and sections, appointing the full complement of officers and noncommissioned officers. On the long march I schooled them in their duties, and as fast as one learned I sent him among the others as a teacher.
Each regiment was made up of about a thousand bowmen, and to each was temporarily attached a company of Mezop musketeers and a battery of artillery-the latter, our naval guns, mounted upon the broad backs of the mighty lidi. There was also one full regiment of Mezop musketeers and a regiment of primitive spearmen. The rest of the lidi that we brought with us were used for baggage animals and to transport our women and children, for we had brought them with us, as it was our intention to march from one Mahar city to another until we had subdued every Mahar nation that menaced the safety of any kingdom of the empire.
Before we reached the plain of Phutra we were discovered by a company of Sagoths, who at first stood to give battle; but upon seeing the vast numbers of our army they turned and fled toward Phutra. The result of this was that when we came in sight of the hundred towers which mark the entrances to the buried city we found a great army of Sagoths and Mahars lined up to give us battle.
At a thousand yards we halted, and, placing our artillery upon a slight eminence at either flank, we commenced to drop solid shot among them. Ja, who was chief artillery officer, was in command of this branch of the service, and he did some excellent work, for his Mezop gunners had become rather proficient by this time. The Sagoths couldn't stand much of this sort of warfare, so they charged us, yelling like fiends. We let them come quite close, and then the musketeers who formed the first line opened up on them.
The slaughter was something frightful, but still the remnants of them kept on coming until it was a matter of hand-to-hand fighting. Here our spearmen were of value, as were also the crude iron swords with which most of the imperial warriors were armed.
We lost heavily in the encounter after the Sagoths reached us; but they were absolutely exterminated-not one remained even as a prisoner. The Mahars, seeing how the battle was going, had hastened to the safety of their buried city. When we had overcome their gorilla-men we followed after them.
But here we were doomed to defeat, at least temporarily; for no sooner had the first of our troops descended into the subterranean avenues than many of them came stumbling and fighting their way back to the surface, half-choked by the fumes of some deadly gas that the reptiles had liberated upon them. We lost a number of men here. Then I sent for Perry, who had remained discreetly in the rear, and had him construct a little affair that I had had in my mind against the possibility of our meeting with a check at the entrances to the underground city.
Under my direction he stuffed one of his cannon full of powder, small bullets, and pieces of stone, almost to the muzzle. Then he plugged the muzzle tight with a cone-shaped block of wood, hammered and jammed in as tight as it could be. Next he inserted a long fuse. A dozen men rolled the cannon to the top of the stairs leading down into the city, first removing it from its carriage. One of them then lit the fuse and the whole thing was given a shove down the stairway, while the detachment turned and scampered to a safe distance.
For what seemed a very long time nothing happened. We had commenced to think that the fuse had been put out while the piece was rolling down the stairway, or that the Mahars had guessed its purpose and extinguished it themselves, when the ground about the entrance rose suddenly into the air, to be followed by a terrific explosion and a burst of smoke and flame that shot high in company with dirt, stone, and fragments of cannon.
Perry had been working on two more of these giant bombs as soon as the first was completed. Presently we launched these into two of the other entrances. They were all that were required, for almost immediately after the third explosion a stream of Mahars broke from the exits furthest from us, rose upon their wings, and soared northward. A hundred men on lidi were despatched in pursuit, each lidi carrying two riflemen in addition to its driver. Guessing that the inland sea, which lay not far north of Phutra, was their destination, I took a couple of regiments and followed.
A low ridge intervenes between the Phutra plain where the city lies, and the inland sea where the Mahars were wont to disport themselves in the cool waters. Not until we had topped this ridge did we get a view of the sea.
Then we beheld a scene that I shall never forget so long as I may live.
Along the beach were lined up the troop of lidi, while a hundred yards from shore the surface of the water was black with the long snouts and cold, reptilian eyes of the Mahars. Our savage Mezop riflemen, and the shorter, squatter, white-skinned Thurian drivers, shading their eyes with their hands, were gazing seaward beyond the Mahars, whose eyes were fastened upon the same spot. My heart leaped when I discovered that which was chaining the attention of them all. Twenty graceful feluccas were moving smoothly across the waters of the sea toward the reptilian horde!
The sight must have filled the Mahars with awe and consternation, for never had they seen the like of these craft before. For a time they seemed unable to do aught but gaze at the approaching fleet; but when the Mezops opened on them with their muskets the reptiles swam rapidly in the direction of the feluccas, evidently thinking that these would prove the easier to overcome. The commander of the fleet permitted them to approach within a hundred yards. Then he opened on them with all the cannon that could be brought to bear, as well as with the small arms of the sailors.
