Here at the bottom of a dying world was the only naturally productive area upon its surface. Here alone were dews and rains, here alone was an open sea, here was water in plenty; and all this was but the stamping ground of fierce brutes and from its beauteous and fertile expanse the wicked remnants of two once mighty races barred all the other millions of Barsoom. Could I but succeed in once breaking down the barrier of religious superstition which had kept the red races from this El Dorado it would be a fitting memorial to the immortal virtues of my Princess—I should have again served Barsoom and Dejah Thoris' martyrdom would not have been in vain.
On the morning of the second day we raised the great fleet of transports and their consorts at the first flood of dawn, and soon were near enough to exchange signals. I may mention here that radio-aerograms are seldom if ever used in war time, or for the transmission of secret dispatches at any time, for as often as one nation discovers a new cipher, or invents a new instrument for wireless purposes its neighbours bend every effort until they are able to intercept and translate the messages. For so long a time has this gone on that practically every possibility of wireless communication has been exhausted and no nation dares transmit dispatches of importance in this way.
Tars Tarkas reported all well with the transports. The battleships passed through to take an advanced position, and the combined fleets moved slowly over the ice cap, hugging the surface closely to prevent detection by the therns whose land we were approaching.
Far in advance of all a thin line of one-man air scouts protected us from surprise, and on either side they flanked us, while a smaller number brought up the rear some twenty miles behind the transports. In this formation we had progressed toward the entrance to Omean for several hours when one of our scouts returned from the front to report that the cone-like summit of the entrance was in sight. At almost the same instant another scout from the left flank came racing toward the flagship.
His very speed bespoke the importance of his information. Kantos Kan and I awaited him upon the little forward deck which corresponds with the bridge of earthly battleships. Scarcely had his tiny flier come to rest upon the broad landing-deck of the flagship ere he was bounding up the stairway to the deck where we stood.
"A great fleet of battleships south-south-east, my Prince," he cried. "There must be several thousands and they are bearing down directly upon us."
"The thern spies were not in the palace of John Carter for nothing," said Kantos Kan to me. "Your orders, Prince."
"Dispatch ten battleships to guard the entrance to Omean, with orders to let no hostile enter or leave the shaft. That will bottle up the great fleet of the First Born.
"Form the balance of the battleships into a great V with the apex pointing directly south-south-east. Order the transports, surrounded by their convoys, to follow closely in the wake of the battleships until the point of the V has entered the enemies' line, then the V must open outward at the apex, the battleships of each leg engage the enemy fiercely and drive him back to form a lane through his line into which the transports with their convoys must race at top speed that they may gain a position above the temples and gardens of the therns.
"Here let them land and teach the Holy Therns such a lesson in ferocious warfare as they will not forget for countless ages. It had not been my intention to be distracted from the main issue of the campaign, but we must settle this attack with the therns once and for all, or there will be no peace for us while our fleet remains near Dor, and our chances of ever returning to the outer world will be greatly minimized."
