Occasionally the water would be too deep for us to wade, and we were obliged to put our weapons on the raft and swim. The Indians followed us pretty closely, and were continually watching for an opportunity to get a good range and give us a raking fire. Covering ourselves by keeping well under the bank, we pushed ahead as rapidly as possible, and made pretty good progress, the night finding us still on the way and our enemies yet on our track. I, being the youngest and smallest of the party, became somewhat tired, and, without noticing it, I had fallen behind the others for some little distance. It was about ten o'clock, and we were keeping very quiet and hugging close to the bank, when I happened to look up to the moonlit sky and saw the plumed head of an Indian peeping over the bank. Instead of hurrying ahead and alarming the men in a quiet way, I instantly aimed my gun at his head and fired. The report rang out sharp and loud on the night air, and was immediately followed by an Indian whoop, and the next moment about six feet of dead Indian came tumbling into the river. I was not only overcome with astonishment, but was badly scared, as I could hardly realize what I had done. I expected to see the whole force of Indians come down upon us. While I was standing thus bewildered, the men, who had heard the shot and the war whoop, and had seen the Indian take a tumble, came rushing back. "Who fired that shot?" cried Frank McCarthy. "I did," replied I, rather proudly, as my confidence returned, and I saw the men coming up. "Yes, and little Billy has killed an Indian stone dead--too dead to skin," said one of the men, who had approached nearer than the rest, and had almost stumbled upon the Indian. From that time forward I became a hero and an Indian-killer. This was, of course, the first Indian I had ever shot, and as I was not then more than eleven years of age, my exploit created quite a sensation. The other Indians, upon learning what had happened to their advance, fired several shots without effect, but which hastened our retreat down the river. We reached Fort Kearny just as the reveille was being sounded, bringing the wounded man with us. After the peril through which we had passed, it was a relief to feel that once more I was safe after such a dangerous initiation. Frank McCarthy immediately reported to the commanding officer and informed him of all that had happened. The commandant at once ordered a company of cavalry and one of infantry to proceed to Plum Creek on a forced march, taking a howitzer with them--to endeavor to recapture the cattle from the Indians.
