I am trying to understand where on today's map of the Punjab, Alexander and his armies returned after a mutiny. The historical accounts (Arrian, for example) suggest he reached the Beas River, which is in today's Indian side of the Punjab. According to historical sources, such as Arrian, he built a giant monument to mark the eastern most point of the campaign there.
It is of course possible, that the Beas River in those days ran differently than today.
Assuming that the ancient sources are correct, is anything known about where on today's map the mutiny took place and the monument would have been built?
