Elephants have fought in human armies for more than three thousand years. Asian powers boasted of their pachyderm power, while the Romans fielded elephants alongside their legendary legions but were, perhaps, too proud to admit that mere animals contributed to victory. Elephants have gored, stomped, and sliced their way through infantry and cavalry with great success. They have also been cut, speared, bombed, and napalmed for their efforts. This is the story of their largely forgotten role in the history of warfare.
