Ok, I'll be the first to admit this one is a little confusing. After all, the whole mystery is more than a little confusing. So here is a list of the bits of evidence we're talking about.
- The Ninth was nearly destroyed in a night assault by the Caledonians during Agricola's northern campaign.
- The last known battle the Ninth was in was Mons Graupius.
- 108 AD, The Ninth built a gate at Eboracum (York).
- Post 117 AD (probably 119 to 121) there was a major rebellion in Britannia.
- 80's AD or 121 AD, there were tiles at Nijmegen (Holland) stamped by the Ninth.
- Tiles similar to those were also found at Carlisle.
- A tombstone at Ferentinum references an emergency in Britannia that required 3,000 reinforcements.
- 122 AD, Hadrian traveled to Britannia to "correct many faults" and he brought with him the Sixth Legion.
- The Sixth legion took the post of Eboracum, which was the Ninth's post. No mention is made of where the Ninth went.
- 142 AD, Governor Carus, who served with the Ninth, became the Governor of Arabia.
- Frontinus writes to Emperor Aurelius reminding him how his grandfather (Hadrian) suffered a major loss of troops to the Jews and the Britons.
- 162 AD, the Aurelian columns don't list the Ninth or Twenty Second legions.
- The Twenty Second probably served in the Jewish wars and the Ninth was stationed in Britannia.
That should just about cover it.
Oh, and The Eagle is not a good film.
