When I exert myself, I can jump to incredible heights. Twenty feet is nothing, but this time I miscalculated. I was several yards from the wall when I took a short run and leaped into the air. Instead of alighting on the top of the wall, as I had planned, I soared completely over it, clearing it by a good ten feet.

Below me were the fighters. Apparently I was going to land right in their midst.

So engrossed were they in their sword play that they did not notice me; and that was well for me; as one of the green men could easily have impaled me on his sword as I dropped upon them.

My man was being hard pressed. It was evident that the green men had given up the notion of capturing him, and were trying to finish him off. One of them had him at a disadvantage and was about to plunge a long-sword through him when I alighted. By rare good luck I alighted squarely upon the back of the man who was about to kill the red man, and I alighted with the point of my sword protruding straight below me. It caught him in the left shoulder and passed downward through his heart, and even before he collapsed I had planted both feet upon his shoulders; and, straightening up, withdrawn my blade from his carcass.

For a moment my amazing advent threw them all off their guard, and in that moment I leaped to the side of the red man and faced his remaining foes, the red blood of a green warrior dripping from my point.

The red man threw a quick glance at me; and then the remaining green men were upon us, and there was no time for words. A fellow swung at me and missed. Gad! what a blow he swung! Had it connected I should have been as headless as a rykor. It was unfortunate for the green man that it did not, for mine did. I cut horizontally with all my Earthly strength, which is great on Earth and infinitely greater on Mars. My long-sword, its edge as keen as a razor and its steel such as only Barsoom produces, passed entirely through the body of my antagonist, cutting him in two.
