By degrees, Mr. Kinzie established still more remote posts, all contributing to the parent post at Chicago; at Milwaukee, with the Menominee; at Rock River with the Winnebago and the Potowatomi; on the Illinois River and the Kankakee with the Prairie Potowatomi; and with the Kickapoo in what was called "Le Large," the widely extended district afterwards converted into Sangamon County. He was appointed Sub-Indian Agent and Government Interpreter, and in these capacities rendered valuable service. About the year 1810, a Frenchman named Lalime was killed by John Kinzie under the following circumstances: Lalime had become insanely jealous of Mr. Kinzie's success as a rival trader, and was unwise enough to threaten to take Kinzie's life. The latter only laughed at the reports, saying "Threatened men live long, and I am not worrying over Lalime's wild talk." Several of his stanchest Indian friends, however, continued to warn him, and he at last consented to carry some sort of weapon in case Lalime really had the folly to attack him. He accordingly took a carving knife from the house and began sharpening it on a grindstone in the woodshed. Young John stood beside him, much interested in this novel proceeding. "What are you doing, father?" he asked. "Sharpening this knife, my son," was the reply. "What for?" said John. "Go into the house," replied his father, "and don't ask questions about things that don't concern you." A few days passed. Nothing happened; but Mr. Kinzie carried the knife. Mrs. Kinzie's daughter by her first marriage was now seventeen years old, and was the wife of Lieutenant Linai Thomas Helm, one of the officers stationed at Fort Dearborn, and Mr. Kinzie frequently went over there to spend the evening. One very dark night he sauntered over to the fort, and was just entering the inclosure, when a man sprang out from behind the gate post and plunged a knife into his neck. It was Lalime. Quick as a flash, Mr. Kinzie drew his own knife and dealt Lalime a furious blow, and a fatal one. The man fell like a log into the river below. Mr. Kinzie staggered home, covered with blood from the deep wound. The late Gurdon S. Hubbard, in a letter to a grandson of John Kinzie's, gives the following account of the affair: 143 Locust St., Chicago, Ill., Feb. 6th, 1884. Arthur M. Kinzie, Esq., My Dear Sir,
