27th.--Two non-commissioned officers of the Fort, assistant Commissary Sergeants, Turner and Sunderland, with two citizens, Messrs. Simmonds and Stewart rode out, after dinner on horseback. They had been but a short time gone, when we heard the reports of several rifles and two or three distinct yells. In a few minutes after we saw one of them, Mr. Turner, come in at full gallop, and a horse without his rider close behind. Mr. Turner informed he had been fired on by the Indians one mile from the Fort, and that the other three had been killed. He himself had received a bullet through his cap. A party was immediately formed, and marched towards the place of ambuscade; on the road they met Mr. Sunderland with his right arm broken and Mr. Simmonds shot through the back. Both their horses had been shot, but luckily carried their riders two hundred yards or more, Mr. Simmonds’ horse fell on him, but in the death plunge left him at liberty. Mr. Sunderland’s horse had fallen, thrown his rider and made for his stable, but dropped dead before he reached it. Mr. Stewart, the fourth of the party was found dead and scalped; some of his clothes had been stripped off, and his body and face were covered with wounds from bullets and knives. The savages had dragged him fifty yards from the road and left him beside a tree, but a faithful dog had remained close to him, and when the poor creature saw the troops, it ran out and conducted them to its unfortunate master. The body was carried into the Fort, a shocking spectacle. The bullet was extracted from Mr. Simmonds’ shoulder without doing any injury, but Mr. Sunderland lost his right arm. The operation was performed next day, at his own request; he bore it with the resolution of a man and a Soldier. Next day a scouting party marched out and scoured the adjacent hammocks, but we saw nothing except the tracks and fires of the Indians.
