Recently I received an email of trivia facts. One of them was that it was still legal to hunt camels in Arizona. This was supposed to be true albeit the last camel hunted in Arizona was hunted in the 1930s. In the late 1840s and 1850s Secretary of War, Jefferson Davis, decided that camels might be cheaply imported in order to replace the role of horses in the Southwest desert.
Davis had taken the idea from Josiah Harlan. And it might been that the US Cavalry became the US Army Camel Corps had not Harlan misunderstood the resistance of American horses, mules, and cows to the aggressive camels. The Camel Corps was disbanded in 1863. Camels were set free in Arizona. "Harlan did not care because he had another brilliant idea." This is yet another adventure of the "man who would be king."
