A Bishop in war game terms means war elephant. A search of war elephant led to this.

The use of war elephants over the centuries has left a deep cultural legacy in many countries. Many traditional war games incorporate war elephants. Shatranj (Persian chess) — from which Modern chess has gradually developed - calls its bishop fil, meaning elephant in Persian. In Spanish and Arabic the bishop piece is called al-fil, and in Russian the bishop is also an elephant (Слон). Similarly in Indian Chaturanga the bishop piece was originally a war elephant (Gaja), which is still the case in Chinese Chess. In the Japanese Shogi game, there used to be a piece known as the "Drunken Elephant"; it was, however, dropped by order of the Emperor Go-Nara and no longer appears in the version played in contemporary Japan.

Elephant armour, originally designed for use in war, is today usually only seen in museums. One particularly fine set of Indian elephant armour is preserved at the Leeds Royal Armouries Museum, whilst Indian museums across the sub-continent display other fine pieces. The architecture of India also shows the deep impact of elephant warfare over the years. War elephant adorn many military gateways, such as those at Lohagarh Fort for example, whilst some spiked, anti-elephant gates still remain, for example at Kumbhalgarh fort. Across India, older gateways are invariably much higher than their European equivalents, in order to allow elephants with howdahs to pass through underneath.
