The entire story is amazing. It really begins with the Battle of Rafa between the Selucids and Ptolomeys. The Selucids brought Indian elephants to battle and the Egyptians brought African elephants. The African elephants were freaked out but the Egyptians won anyway. Part of the reason they won is because for the first time since the Greeks ruled Egypt they allowed native Egyptians into the army. One theory is that these native Egyptians realized that killing Greeks wasn't that hard and this may have led to the revolt.

After several years of war, Horwennefer and part of his army was besieged for months in a fortress, I think he was banking on a high Nile to bring relief of the siege, but eventually his army surrendered or the fort was stormed and he was executed. The Greek Pharoahs thought this was the end of it but his son had his own coronation and kept the war going even longer.

The son, Anhkwennefer, fought for a long time and at one point the rebels took cities in the Delta, or Northern Egypt. The Greeks suspected the Nubians of aiding Anhkwennefer and the rebels but I don't think that was ever confirmed. In the end the Greek Pharoah offered an amnesty if the remainig fighters surrendered, and when they did he had them tortured and executed, Anhkwennefer too.

Another important aspect of this conflict is the control of the Ptolomiac government. The Ptolomeys had lots of court intrigues. When the Greek Pharoah that was in charge when the revolt began died with only a single heir, his close advisors murdered the mother and other advisors so they could control the child Pharoah. This is the time when the Macedonian King and Selucid King attacked and siezed parts of the Egyptian Kingdom. There was even more drama when a Greek general used a public appearance by the child Pharoah to publicly accuse the killer advisors of killing the Pharoah's mother. He got a crowd worked up and they attacked the royal procession and killed the advisors. The general then took the young Pharoah under his wing.

I have wanted to write a book about this since 2017 but issues with the health of a family member take up so much time I never got back into it.

There is little info on Wikipedia.

Most of the information about this I got from reading research papers. There are lots of things like the Rosetta Stone that reference the revolt, but the Ptolomeys wanted to destroy all evidence of it. They have found papyrus fragments that give us a little info, that's how we know about the families of the warriors being sold into slavery. There was one document that implied the Ptolomeys were concerned that Hannibal would join the rebels after the defeat of Carthage.

>The native Egyptians in Thebaid ("Upper Egypt", ironically now in the south of modern Egypt)

Isn't it Upper Egypt because the Nile flows "backwards" and this is upriver? Rivers generally flow "downward" based on elevation, so upper Egypt was the "higher" ground.
