Sorry, Kevin, I would never had noticed that, nor do I really understand your statement. I was always a C student growing up in English / Literature. However, it sounds like Augustus was MORE than angry.
I'd have to check Tacitus to see how he phrases it in the original, but if he did use the imperative mood it was an abrupt, angry, nasty, snarky statement. If he used the subjunctive mood, it would have been more like a sad lament. We don't use the subjunctive mood that much in English any more , oh would that we did. I was blessed, absolutely blessed, by going to both a high school and a university where all students were required to study Latin, some philosophy classes were taught in Latin (as were those textbooks also in Latin) and ancient Greek was strongly encouraged. I must admit, though, there have been times I felt like Mr. Chips. More baffling than enlightening.PS Edit. I just looked it up. It's not from Tacitus but from Suetonius, his De Vita Caesaraum and he did use the imperative mood so I Guess he really was put out by their loss. I suspect the men of those three legions were, too.
Thank you. From my readings, I understood Augustus was angry and terrified by that loss. Well beyond the “omg, this is bad” mood.
