Tiberius was a piece of work. Doing his thing on Capris. Too bad Drusus died (or murdered), they ended up getting Caligula. A true madman. On his one foreign expedition to Britannia, he had a mutiny. But instead of decimation he had the legions collect sea shells and rocks, and they came back to Rome where the madman held a Triumph for himself and added Britannacus to his long list of names. Just when the Romans thought they were out of the pan, they found themselves in the fire. But strangely, according to what is written and generally accepted, this led to Claudius who had mutiny when sending his legions to cross the English Channel. I’ll have to recheck this but I think he threatened decimation and that was enough to get their sandles on the boats. But he found significant resistance and if it weren’t for the traitorous queen of the Brigantes very well may have been pushed back across the channel. Claudius showed up with Elephants in person well after they had crossed the Thames. Funny how that works. The class dunce pulled off what Caesar couldn’t.
In all fairness to Julius Caesar, he had bigger fish to fry with the Senate.
