Kraxis,

I can't say that I disagree about Beneventum. It really doesn't fit the mould too well anyway, as it started as a night attack. As such it doesn't really lend itself to easy quantification or classification in the context of other battles. The Romans weren't able to follow it up, which suggests that they were badly bloodied rather than stunningly victorious. The Pyrrhic victories were similar in that regard, he couldn't follow up.
