Assured of the correctness of his theory, Julian 5th withdrew in his own flag ship to a remote part of the world, taking with him the few remaining cruisers of the Fleet. Orthis searched for them for months, but it was not until the close of the year 2050 that the two fleets met again and for the last time. Julian 5th had by this time perfected the plan for which he had gone into hiding, and he now faced the Kalkar fleet and his old enemy, Orthis, with some assurance of success. His flag ship moved at the head of the short column that contained the remaining hope of a world and Julian 5th stood upon her deck beside a small and innocent looking box mounted upon a stout tripod. Orthis moved to meet him—he would destroy the ships one by one as he approached them. He gloated at the easy victory that lay before him. He directed the electronic rifle at the flag ship of his enemy and touched a button. Suddenly his brows knitted. What was this? He examined the rifle. He held a piece of aluminum before its muzzle and saw the metal disappear. The mechanism was operating, but the ships of the enemy did not disappear. Then he guessed the truth, for his own ship was now but a short distance from that of Julian 5th, and he could see that the hull of the latter was entirely coated with a grayish substance that he sensed at once for what it was—an insulating material that rendered the aluminum parts of the enemy’s fleet immune from the invisible fire of his rifle. Orthis’ scowl changed to a grim smile. He turned two dials upon a control box connected with the weapon and again pressed the button. Instantly the bronze propellers of the Earth Man’s flag ship vanished in thin air, together with numerous fittings and parts above decks. Similarly went the exposed bronze parts of the balance of The International Peace Fleet, leaving a squadron of drifting derelicts at the mercy of the foe. Julian 5th’s flag ship was at that time but a few fathoms from that of Orthis. The two men could plainly see one another’s features. Orthis’ expression was savage and gloating, that of Julian 5th sober and dignified.
