Does anyone have any information or resources regarding the sorts of weapons used by the various Indian subcontinent kingdoms in the 300s BC - 100 BC?

I'm working on a historical fantasy book set in the late Hellenistic era that takes place in part in the subcontinent, and I have found no resources or information about weapons or armor used at that time in the subcontinent.

Thanks.

I've read Diodorus and am superficially familiar with Strabo's work, though I haven't read it in careful detail. I'll look into Philip de Souza's work as well.

Thanks for the suggestion.
