During the Battle of Pelusium in 525 BC, the invading Persians used cats against the Egyptians and were victorious, successfully annexing Egypt to the Achaemenid Empire.
Polyaenus, "a retired Macedonian general more interested in novelty than historical accuracy",[4] claims that, according to legend, Cambyses captured Pelusium by using a clever strategy. The Egyptians regarded certain animals, especially cats, as being sacred (they had a cat goddess named Bastet), and would not injure them on any account. Polyaenus claims that Cambyses had his men carry the "sacred" animals in front of them to the attack. The Egyptians did not dare to shoot their arrows for fear of wounding the animals, and so Pelusium was stormed successfully. This would be an early form of psychological warfare.[5]
What animals do you think should be militarized and how do you think they should be used?
