In 1846 a well-to-do neighbor, Edward Trimble, made up a party, in which an older brother of Anson's, Aaron Cone, was to go. Obtaining permission of his father, Anson, then but a youth of eighteen, assisted in helping the train off, and drove with the party for some distance. When the time arrived for him to return home (his dejected appearance probably indicating his longing to go on with the emigrants) Trimble said to him: "Anson, I don't advise or ask you to go to Oregon; but if you are bound to, you may go with me." "I have no outfit," said the young man. "I have $1,000," answered Trimble; "and as long as that lasts you shall have your share of it." Anson went. His patron, however, never reached Oregon. Trimble was one of the comparatively few who fell a victim to the treachery of the Indians. He was killed by the Pawnees, on the Platte River, near the big island. He had been selected captain of the company of forty-three wagons which was made up at Saint Joe, where the train crossed the Missouri, and took the route south of the Platte. At a point opposite the big island, as then known, the cattle were stampeded by the Pawnees, and driven away, so that the train was left entirely without teams. Trimble started out to hunt the animals; but his wife, seeing that he had no arms, said to him, "Edward, you had better take your rifle." He answered, "I do not need it; I am only going to look for the trail." But reaching a knoll and finding the trail of the lost stock, which led to the river, he and a man named Harris rode on without stopping, until they discovered the cattle on the island. Going down to the river side, however, they were suddenly confronted by a party of armed Pawnees, who had secreted themselves under the steep bank. Harris then, in his excitement, left his horse, and Trimble delaying for him was shot by the Indians. His body was not recovered but arrows stained with blood were found, which had probably been shot through his body. These were preserved by Mrs. Trimble, and it is thought that they are still in possession of the family; a daughter of Trimble, having become Mrs. Pomeroy, of Pomeroy, Washington.
