When was the dagger vs the pugio used

[Tarbicus]

There were even laws forbidding the removal of spolia from a house's walls, even if the property exchanged hands.

I’ve never heard that. Do you have any links to reading material on it, I’d like to read more about it.

I read it last year, but it's mentioned in the Ancient Warfare article by Ross Cowan which you can now download as a PDF:

BTW, IIRC swimming as part of training I believe was a later addition.

I stand corrected.

Well, if you ever come up with anything to contradict it do post it. I actually can't remember the reference, and I just had a horrid thought it might have been from a novel. But I'm sure it's one of the more reputable authors if so, otherwise it wouldn't have stuck in my scatty mind :? Something to do with more drownings at Actium weren't from the weight of armour but because the men couldn't swim? Roma by Steven Saylor? If so, he has a whole load of primary references in his bibliography.
