That our principal movements were known to the First Born I could not have doubted, in view of the attack of the fleet upon us the day before, nor could the stopping of the pumps of Omean at the psychological moment have been due to chance, nor the starting of a chemical combustion within the one corridor through which we were advancing upon the Temple of Issus been due to aught than well-calculated design.

And now the dropping of the steel gate to pen me effectually between fire and flood seemed to indicate that invisible eyes were upon us at every moment. What chance had I, then, to rescue Dejah Thoris were I to be compelled to fight foes who never showed themselves. A thousand times I berated myself for being drawn into such a trap as I might have known these pits easily could be. Now I saw that it would have been much better to have kept our force intact and made a concerted attack upon the temple from the valley side, trusting to chance and our great fighting ability to have overwhelmed the First Born and compelled the safe delivery of Dejah Thoris to me.
