Gentle Friends,
For many years, it has been my understanding that the stilted warriors were trained to do battle with the enemy who occupied the Howdahs on the backs of the elephants. The stilts placed the warriors at approximately the same height as the enemy who were riding the elephants. The stilted warriors did not actually do battle with the large elephants. Rather, they fought those who rode the elephants.
Unfortunately, I cannot refer you to any specific documentation of my understanding. If anyone discovers documentation of a different function for the stilts, please let me know.
Warmest personal regards,
Pat
