He leaned on me, hobbling along as best he could, and bravely too, although, at every step he groaned with pain. I had become somewhat attached to Willis. He was egotistic--just a little--but harmlessly so, and his senses were sound and his will was good; I had, too, abundant evidence of his liking for me. He was a strapping fellow, more than six feet tall and as strong as a bullock. So, while I fully understood the danger in tying myself to a wounded comrade, I could not find it in my heart to desert him, especially since he showed such determination to save himself. Besides, I knew that he was quick-witted and country-bred; and I had great hope that he would prove more of a help than a hindrance. We followed a few stragglers who had passed us and were now running up the creek seeking a crossing. The stream was shallow, but the banks were high, and in most places steep. Men were crossing at almost all points. Slowly following the hurrying groups of twos and threes who had outstripped us, we found at length, a place that seemed fordable for Willis. It was where a small branch emptied into the creek; and by getting into the branch, above its mouth, and following its course, we should be able to cross the creek. "Lord! I am thirsty," said Willis; "but look how they have muddied the branch; it's as bad as the creek." "That water wouldn't do us any good," I replied. "No," said he; "it would make us sick." "But what else can we do?" "Let's go up the branch, a little," said he. All sounds in our rear had long since died away. The sun was yet shining, but in the thick forest it was cool and almost dark. I hoped that water, food, and a little rest would do us more good than harm--that time would be saved, in effect. A hundred yards above the mouth of the branch, we found the water clear. I still had my canteen, my haversack with a cup in it, and food. Willis lay on the ground near the stream, while I filled my canteen; I handed it to him, and then knelt in the wet sand and drank. The spot might have been well chosen for secrecy; indeed, we might have remained there for days were it not for fear. A giant poplar had been uprooted by some storm and had crushed in its fall an opening in, the undergrowth. The trunk spanned the little brook, and the boughs, intermingling with the copse, made a complete hiding-place. I helped Willis to cross the branch; then we lay with the log at our backs and completely screened from view. Willis drank another great draught of water. I filled the canteen again, and examined his wound. His knee was stiff and much swollen; just under the knee-cap was a mass of clotted blood; this I washed away, using all the gentle care at my command, but giving him, nevertheless, great pain. A small round hole was now sean, and by gently pressing on its walls, I thought I detected the presence of the ball. "Sergeant," said I, "it's in there; I don't believe it's more than half an inch, deep." "Then pull it out," said Willis,
