Tom Lyons and Angus Campbell built an Empire, but Angus Campbell died in 1892, and Tom Lyons wife ran off after Tom shot and killed her lover. Her lover shot first, and Tom was never charged....This truly was the wild west! So the widowed Ida Campbell and the estranged Tom Lyons kept the business together, married, and had a very successful marriage, and a very successful cattle empire until... Tom was murdered in 1917 by a hired assassin, Felix Jones, presumably hired by one of the homesteaders against whom Tom had pressed charges for Horse theiving, for which he had spent several years in prison.
The National Park Service published "The Cattleman's Empire" in the late 1960's in order to document the history of ranching, especially ranching on a grand scale, that occured in the post Civil war era. There were just a few ranches in all of America that achieved the level of size and importance of the L.C. The King Ranch in Texas still survives, and is probably the most famous, but it's original ranch house burned down, and what is there now was built in the 1930's. The XIT in the pan handle of Texas was the largest, at 3 million acres, but nothing survives today. The L.C. is unique in that it is the only surviving great ranch house of the period left in the U.S. Unlike most historic buildings and historic sites in America, it is not just an empty historic building, there is also a collection of period Art and Antiques which lavishly decorates the Ranch, courtesy of the Ocheltree Family, which has spent the last 55 years and 4 generations working on the L.C. with the goal of restoring the Lyons and Campbell Ranch Headquarters "to its former grandeur", and still working towards that goal.
There are several very good books telling the story of Tom Lyons. Most recent and certainly the most fascinating is
The Last Train To El Paso which focuses on Tom's murder and the trial of his hired assassin, Felix Jones.
TRIUMPH and TRAGEDY was written by Tom's step-grandaughters, and is an invaluable resource,
impeccibly researched, with lots of historic pictures.
Recollections of a Western Ranchman is a rather impartial account of life in the Gila by Captain William French,
a retired army officer with frequent references to Tom Lyons and the L.C.
