Vastus with the red men, guided by Xodar, were to land within the
garden of Issus or the surrounding plains; while Carthoris, Kantos Kan,
and I were to lead our smaller force from the sea of Omean through the
pits beneath the temple, which Carthoris knew so well.

I now learned for the first time the cause of my ten ships' retreat
from the mouth of the shaft. It seemed that when they had come upon
the shaft the navy of the First Born were already issuing from its
mouth. Fully twenty vessels had emerged, and though they gave battle
immediately in an effort to stem the tide that rolled from the black
pit, the odds against them were too great and they were forced to flee.

With great caution we approached the shaft, under cover of darkness.
At a distance of several miles I caused the fleet to be halted, and
from there Carthoris went ahead alone upon a one-man flier to
reconnoitre. In perhaps half an hour he returned to report that there
was no sign of a patrol boat or of the enemy in any form, and so we
moved swiftly and noiselessly forward once more toward Omean.

At the mouth of the shaft we stopped again for a moment for all the
vessels to reach their previously appointed stations, then with the
flagship I dropped quickly into the black depths, while one by one the
other vessels followed me in quick succession.

We had decided to stake all on the chance that we would be able to
reach the temple by the subterranean way and so we left no guard of
vessels at the shaft's mouth. Nor would it have profited us any to
have done so, for we did not have sufficient force all told to have
withstood the vast navy of the First Born had they returned to engage
us.

For the safety of our entrance upon Omean we depended largely upon the
very boldness of it, believing that it would be some little time before
the First Born on guard there would realize that it was an enemy and
not their own returning fleet that was entering the vault of the buried
sea.

And such proved to be the case. In fact, four hundred of my fleet of
five hundred rested safely upon the bosom of Omean before the first
shot was fired. The battle was short and hot, but there could have
been but one outcome, for the First Born in the carelessness of fancied
security had left but a handful of ancient and obsolete hulks to guard
their mighty harbour.

It was at Carthoris' suggestion that we landed our prisoners under
guard upon a couple of the larger islands
