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.

Keep your face to the sunshine and you cannot see a shadow

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 greater Helium. Several others attempted to escape, but they were soon surrounded by thousands of tiny individual fliers, and above each hung a monster battleship of Helium ready to drop boarding parties upon their decks.

Within but little more than an hour from the moment the victorious Zodangan squadron had risen to meet us from the camp of the besiegers the battle was over, and the remaining vessels of the conquered Zodangans were headed toward the cities of Helium under prize crews.
