Caesar's Commentaries on the Gallic and Civil Wars

While the translation is okay and the book itself is interesting, many of the translator's notes are shockingly inaccurate. If you want a deeper insight into Caesar I would pick a more modern edition.

Great translation of Caesar's classic, with plenty of descriptive footnotes, which although numerous, add to the book. However does require a large screen or some zooming to read as it is a scanned copy of a book. Possibly the best (English) copy of Caesar's De Bello Gallico on the Play Store.
