The failure of the camel in the United States was not due to its capability; every test showed it to be a superior transport animal. It was instead the nature of the beasts which led to their demise-they smelled horrible, frightened horses, and were detested by handlers accustomed to the more docile mules. Two private importations of camels followed the government experiment. On October 16, 1858, Mrs. M. J. Watson reported to Galveston port authorities that her ship had eighty-nine camels aboard, and claimed that she wanted to test them for purposes of transport. One port official, however, felt that she was using the camels to mask the odor typically associated with a slave ship and refused her petition to unload the cargo. After two months in port, Mrs. Watson sailed for the slave markets in Cuba after dumping the camels ashore in Galveston, where they wandered about the city and died from neglect and slaughter around the coastal sand dunes. A second civilian shipment of a dozen camels arrived at Port Lavaca in 1859, where it met a similar fate.
I have not been to Cuba, however..if they took care of their camels like most do their horses..I can't see many of them ever having survived..I can't really see or dig up any information on them. Other than a Resort has a few on site for tourist rides/attraction.
