I've just finished reading Thucydides "History of the Peloponnesian War" (the Penguin Classics edition, translated by Rex Warner) and of course it doesn't include what happens at the very end of the war (after 411 BC) since Thucydides didn't get that far. The last part it gets to is the Athenian Victory at Cynossema and it literally finishes mid-sentence!
I know that Xenophon finished off the account, but does anyone know if that is actually available as a book on its own (it would be nice if it was also a Rex Warner translation, for consistency). If anyone has the actual title of the book that covers this that I may be able to find on a bookshop's shelves too then I'd appreciate it!
(I do have Kagan's one-volume Peloponnesian War book as well and I'm sure all the missing events from the end are covered in there - but I'd like to have a translation from the original source to go with Thucydides as well!)
to answer my own question, i think the Rex Warner translation of what I'm after is Xenophon's "History of My Times" by Penguin Classics. This apparently is what other folks call "Hellenica". https://www.penguinrandomhouse.com/books/261200/a-history-of-my-times-by-xenophon/
I opted to go for the Landmark version though since that'd have footnotes and maps too (and I'm picking up the Landmark Thucydides while I'm at it).
