War pig


War pigs are pigs reported to have been used in ancient warfare as military animals, mostly as a countermeasure against war elephants.
In the first century BC, Lucretius noted that humans may have attempted to launch wild beasts, such as lions or "savage boars", against the enemy, but with catastrophic results. In 272 BC, it was recorded that the Romans used wild boars in their fight against the war elephants of the Tarantines.
According to legend recounted in the "Alexander Romance" by Pseudo-Callisthenes, Alexander the Great learned about this "secret weapon" against war elephants from Porus in India.
Pliny the Elder reported that "elephants are scared by the smallest squeal of the hog". Aelian confirmed that elephants were frightened by squealing pigs, and reported that the Romans exploited squealing pigs to repel the war elephants of Pyrrhus in 275 BC. Procopius, in History of the Wars, records that the defenders of Edessa suspended a squealing pig from the walls to frighten away Khosrau's single siege elephant in the sixth century AD.
Historical accounts of incendiary pigs or flaming pigs were recorded by the military writer Polyaenus and by Aelian. Both writers reported that Antigonus II Gonatas' siege of Megara in 266 BC was broken when the Megarians doused some pigs with combustible pitch, crude oil or resin, set them alight, and drove them towards the enemy's massed war elephants. The elephants bolted in terror from the flaming, squealing pigs, often killing great numbers of their own soldiers by trampling them to death. According to an account, Gonatas later made his mahouts keep a swine among elephants to accustom the animals to pigs and this practice was immortalized by a Roman bronze coin dating back to his time, which showed an elephant on one side and a pig on the other.
As late as the 16th century, the supposed terror of the elephant for the squealing pig was reported by Reginald Scott.
