"On my sword, I swear it," he said; and then I left them and made my way cautiously toward the Panar camp.

Once again, as upon so many other occasions, I used the tactics of another race of red warriors—the Apaches of our own Southwest— worming my way upon my belly closer and closer toward the lines of the enemy. I could see the forms of warriors clustered about their fires, and I could hear their voices and their rough laughter; and, as I drew nearer, the oaths and obscenities which seem to issue most naturally from the mouths of fighting men; and when a gust of wind blew from the camp toward me, I could even smell the sweat and the leather mingling with the acrid fumes of the smoke of their fires.

A sentry paced his post between me and the fires; when he came closest to me, I flattened myself upon the ground. I heard him yawn. When he was almost on top of me, I rose up before him; and before he could voice a warning cry, I seized him by the throat. Three times I drove my dagger into his heart. I hate to kill like that; but now there was no other way, and it was not for myself that I killed him—it was for Llana of Gathol, for Tara of Helium, and for Dejah Thoris, my beloved princess.

Just as I lowered his body to the ground, a warrior at a nearby fire arose and looked out toward us. "What was that?" he asked his fellows.

"The sentry," one of them replied; "there he is now." I was slowly pacing the post of the departed, hoping none would come to investigate.

"I could have sworn I saw two men scuffling there," said the first speaker.

"You are always seeing things," said a third.

I walked the post until they had ceased to discuss the matter and had turned their attention elsewhere; then I knelt beside the dead man and removed his harness and weapons, which I immediately donned. Now I was, to outward appearances anyway, a soldier of Hin Abtol, a Panar from some glazed, hothouse city of the frozen North.

Walking to the far end of my post, I left it and entered the camp at some distance from the group which included the warrior whose suspicions I had aroused. Although I passed close to another group of warriors, no one paid any attention to me. Other individuals were wandering around from fire to fire, and so my movements attracted no notice.

I must have walked fully a haad inside the lines away from my point of entry before I felt that it would be safe to stop and mix with the warriors. Finally I saw a lone warrior sitting beside a fire, and approached him.

"Kaor!" I said, using the universal greeting of Barsoom.
