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.
