Interesting article; The author has brought together a lot of information from ancient Sanskrit sources but missed out a few.

The most well-known text (mentioned in the article) on "Elephant Science" is Matanga lila (https://en.wikipedia.org/wiki/Matanga_Lila) but there is also Gaja Sastra (https://en.wikipedia.org/wiki/Gajashastra) and chapters from Manasollasa by Somesvara (https://en.wikipedia.org/wiki/Manasollasa) an encyclopedic work in the style of Arthashastra. There is doubtless more in other ancient texts in various Indian languages which i am as yet not aware of.

The best description of the use of a war elephant occurs in the Mahabharata in the battle between King Bhagadatta (https://en.wikipedia.org/wiki/Bhagadatta) seated on his favourite war elephant Supratika (https://en.wikipedia.org/wiki/Supratika) and the Pandava army; first with Bhima and then with Arjuna. When mounted on Supratika, Bhagadatta was said to be invincible and proves it on the 12th day of the kurukshetra war when he single-handedly defeats the Pandava army and almost killing Bhima, the Pandava warrior who is the most skilled in elephant warfare with knowledge of their vital points and how to attack them. Arjuna then comes in to save the day and slays both Supratika and Bhagadatta. The is is one of the best passages in the Mahabharata on pure valour in warfare and worth reading in entirety (from here) - https://sacred-texts.com/hin/m07/m07024.htm
