U.S. Army Camel Corps, a failed experiment in the mid-1800s by the United States Army to introduce camels as beasts of burden in desert regions of the American Southwest. It was hoped that camels would be an effective replacement for horses and mules, which were adversely affected by the region’s extreme temperatures. Although the Camel Corps was never officially constituted as a U.S. Army unit, this is the name by which the experiment is most commonly known.

　　The notion of camels as American desert pack animals dates back as far as the 1830s, but the army did not officially start considering the idea until 1848, when Maj. Henry C. Wayne of the Quartermaster Corps reached out to Mississippi Sen. Jefferson Davis seeking support. Davis, who had spent time in the Southwest during the Mexican-American War (1846–48) was intrigued but was unable to convince Congress to provide funding for the experiment until 1855.

　　A total of $30,000 was budgeted by Congress to purchase camels from sellers in the Mediterranean, with Wayne being authorized to make the purchase. The USS Supply, commanded by David Dixon Porter, who, as the son of a diplomat, had spent time in the Middle East as a child and was familiar with camels, was assigned to bring the camels back to the United States. Porter made extensive alterations to the Supply to accommodate the camels, including the construction of a 60-foot (18.3-meter) camel barn with stalls and a unique ventilation system that forced air from the ship’s sails into and out of the stalls. A special harness system was also devised to keep the animals safe during bad weather.

　　While Porter first took the ship to Italy on a separate supply mission, Wayne visited various European cities to learn more about the animals, including a trip to the Royal Zoological Society in London, a camel caravan in Pisa, Italy, and on to Paris to discuss the military use of camels with the French Camel Corps, which had relied extensively on camels in Algeria. Once reunited, Wayne and Porter visited Turkey, Malta, Egypt, and Crimea, where they talked with British officers regarding their use of camels during the Crimean War and elsewhere. A total of 33 dromedary and Bactrian camels were purchased in Egypt, Tunisia, and Turkey, along with saddles and other equipment. One Bactrian camel was so large that a hole had to be cut in the Supply’s deck to accommodate its humps. Five Arab and Turkish camel drivers were also hired to show American military personnel how to train and ride the balky beasts.

　　After a relatively uneventful journey, the USS Supply arrived in Indianola, Texas, on May 14, 1856, with 34 camels—one adult camel died during the voyage from Smyrna (now İzmir), Turkey, but six calves were born, two of which survived. The camels had been acquired for a total of just $8,000, so Porter was immediately ordered back to the Middle East to purchase more. He returned six months later with an additional 41 camels. While Porter had been away, the first caravan of camels was taken to Camp Verde, Texas, approximately 60 miles (96.6 km) north of San Antonio, where Wayne immediately began evaluating their capabilities as animals of war and transportation. On the former, they failed miserably, primarily because the structure of their noses impeded breathing during hard exertion, reducing their sustained speed. Their size also made them ineffective in close-quarter situations. But most importantly, the camels were greatly disliked by soldiers and other animals because of their odor and their disturbing habit of biting, spitting, or explosively defecating on anyone who tried to discipline them. They also required constant care to prevent a very contagious and difficult to treat form of mange from developing.

　　As pack animals, however, the camels excelled. During numerous experiments, they successfully carried packs twice as heavy as could be carried by horses or mules, more easily tolerated the desert heat, required less water and food, and were able to traverse deep streams and mountain trails with ease. In October 1856 Wayne wrote: “The usefulness of the camels in the interior of the country is no longer a question here in Texas among those who have seen them at work, or examined them with attention.”

Lee, who drove a small caravan on a long-range patrol in 1860. He found them effective and declared their benefits, but his admiration was lost with the start of the American Civil War (1861–65). The caravan of camels stationed at Camp Verde, Texas, was captured by Confederate forces early in the conflict, though the Confederates never employed the animals as part of their war effort. A second caravan, stationed at Camp Tejon, California, remained in Union hands but was transferred to various posts over the course of the war because no one could conceive of an effective use for them. Union Secretary of War Edwin M. Stanton thought the camels worthless and finally ordered them to be sold. The U.S. Army found new homes for the camels stationed in California by the war’s end; those in Texas were recaptured by Union forces and sold in 1866.

　　The new owners ranged from circus proprietors to gold prospectors to ranchers, most of whom had little idea how to train or care for the animals. As a result, many camels were simply abandoned. A good number acclimated to living in the harsh wilds of the American Southwest and found a permanent home there, roaming the desert unbothered. Camel sightings were reported in the region as recently as the 1940s.
