THE AIR BATTLE

Two hours after leaving my palace at Helium, or about midnight, Kantos Kan, Xodar, and I arrived at Hastor.

Carthoris, Tars Tarkas, and Hor Vastus had gone directly to Thark upon another cruiser.

The transports were to get under way immediately and move slowly south. The fleet of battleships would overtake them on the morning of the second day.

At Hastor we found all in readiness, and so perfectly had Kantos Kan planned every detail of the campaign that within ten minutes of our arrival the first of the fleet had soared aloft from its dock, and thereafter, at the rate of one a second, the great ships floated gracefully out into the night to form a long, thin line which stretched for miles toward the south.

It was not until after we had entered the cabin of Kantos Kan that I thought to ask the date, for up to now I was not positive how long I had lain in the pits of Zat Arras.

When Kantos Kan told me, I realized with a pang of dismay that I had misreckoned the time while I lay in the utter darkness of my cell. Three hundred and sixty-five days had passed--it was too late to save Dejah Thoris.

The expedition was no longer one of rescue but of revenge.
