Since you two are interested, do you know the Landmark editions of these books (Landmark Herodotus, Landmark Thucydides)? I've got the Landmark Herodotus, but not yet bought the Landmark Thucydides. They're great, because they give all the modern equivalents for the cities and regions mentioned by the two. That's particularly important where Herodotus is concerned, where you often don't have the faintest idea where you are. They also have maps. They're also, incidentally, very pretty hardbacks, but not cheap, of course.
Must get round to reading a good history of the Vietnamese wars, including the French aspect of it, in the 50s. Do you know a book called A Bright Shining Lie, by Neil Sheehan? It made a big splash when it came out. But Max Hastings is a good historian. Must give that a go.
