The banners of Helium had been strung from stem to stern of each of our mighty craft, but the Zodangans did not need this sign to realize that we were enemies, for our green Martian warriors had opened fire upon them almost as they left the ground. With their uncanny marksmanship they raked the oncoming fleet with volley after volley.
The twin cities of Helium, perceiving that we were friends, sent out hundreds of vessels to aid us, and then began the first real air battle I had ever witnessed.
The vessels carrying our green warriors were kept circling above the contending fleets of Helium and Zodanga, since their batteries were useless in the hands of the Tharks who, having no navy, have no skill in naval gunnery. Their small-arm fire, however, was most effective, and the final outcome of the engagement was strongly influenced, if not wholly determined, by their presence.
At first the two forces circled at the same altitude, pouring broadside after broadside into each other. Presently a great hole was torn in the hull of one of the immense battle craft from the Zodangan camp; with a lurch she turned completely over, the little figures of her crew plunging, turning and twisting toward the ground a thousand feet below; then with sickening velocity she tore after them, almost completely burying herself in the soft loam of the ancient sea bottom.
A wild cry of exultation arose from the Heliumite squadron, and with redoubled ferocity they fell upon the Zodangan fleet. By a pretty maneuver two of the vessels of Helium gained a position above their adversaries, from which they poured upon them from their keel bomb batteries a perfect torrent of exploding bombs.
Then, one by one, the battleships of Helium succeeded in rising above the Zodangans, and in a short time a number of the beleaguering battleships were drifting hopeless wrecks toward the high scarlet tower of
