camel cavalry

From a history of Confederate president Jefferson Davis' camel cavalry:

In 1863, a camel-express service was tried between New San Pedro and Tucson, Arizona, but with only limited success. Around that same time a group of Mexicans loaded up some camels on wagons with the intention of making beasts of burden out of them, but abused them so severely that most of the animals died.

There are so many nonsensical things about that. Not to mention that anything concerning dromedaries or Jefferson Davis may be considered comical.
