[EX Q]: Question: How old was Greek George when the camels were finally auctioned off? Passage:Ali was one of several men hired by the United States Army to introduce camels as beasts of burden to transport cargo across the "Great American Desert." Eight of the men – including Ali – were of Greek origin. They arrived at the Port of Indianola in Calhoun County, Texas on the . The book Go West Greek George by Steven Dean Pastis, published in both Greek and English, specifically identifies all eight men. These pioneers were Yiorgos Caralambo (later known as Greek George), Hadji Ali (Hi Jolly, a.k.a. Philip Tedro), Mimico Teodora (Mico), Hadjiatis Yannaco (Long Tom), Anastasio Coralli (Short Tom), Michelo Georgios, Yanni Iliato, and Giorgios Costi. The Americans acquired three camels in Tunis, nine in Egypt and 21 in Smyrna: 33 in all. Ali was the lead camel driver during the US Army's experiment with the U.S. Camel Corps in using camels in the dry deserts of the Southwest. After successfully traveling round trip from Texas to California, the experiment failed, partly due to the problem that the Army's burros, horses, and mules feared the large animals, often panicking, and the tensions of the American Civil War led to Congress not approving more funds for the Corps. In 1864, the camels were finally auctioned off in Benicia, California, and Camp Verde, Texas. Ali was discharged from the Quartermaster Department of the U.S. Army at Fort McDowell in 1870.
