Each carried a strange banner swung from stem to stern above the upper works, and upon the prow of each was painted some odd device that gleamed in the sunlight and showed plainly even at the distance at which we were from the vessels. I could see figures crowding the forward decks and upper works of the air craft. Whether they had discovered us or simply were looking at the deserted city I could not say, but in any event they received a rude reception, for suddenly and without warning the green Martian warriors fired a terrific volley from the windows of the buildings facing the little valley across which the great ships were so peacefully advancing. Instantly the scene changed as by magic; the foremost vessel swung broadside toward us, and bringing her guns into play returned our fire, at the same time moving parallel to our front for a short distance and then turning back with the evident intention of completing a great circle which would bring her up to position once more opposite our firing line; the other vessels followed in her wake, each one opening upon us as she swung into position. Our own fire never diminished, and I doubt if twenty-five per cent of our shots went wild. It had never been given me to see such deadly accuracy of aim, and it seemed as though a little figure on one of the craft dropped at the explosion of each bullet, while the banners and upper works dissolved in spurts of flame as the irresistible projectiles of our warriors mowed through them. The fire from the vessels was most ineffectual, owing, as I afterward learned, to the unexpected suddenness of the first volley, which caught the ship’s crews entirely unprepared and the sighting apparatus of the guns unprotected from the deadly aim of our warriors. It seems that each green warrior has certain objective points for his fire under relatively identical circumstances of warfare. For example, a proportion of them, always the best marksmen, direct their fire entirely upon the wireless finding and sighting apparatus of the big guns of an attacking naval force; another detail attends to the smaller guns in the same way; others pick off the gunners; still others the officers; while certain other quotas concentrate their attention upon the other members of the crew, upon the upper works, and upon the steering gear and propellers. Twenty minutes after the first volley the great fleet swung trailing off in the direction from which it had first appeared. Several of the craft were limping perceptibly, and seemed but barely under the control of their depleted crews. Their fire had ceased
