Book III of Caesar's
De Bello Civili
is arguably the most interesting he ever wrote, containing as it does the two major campaigns of Dyrrachium and of Pharsalus - Caesar's titanic struggle with his arch-rival Pompey. This classic edition remains an extremely serviceable introduction, designed with the comparative beginner in mind.
An introduction contains the historical background; extensive annotation gives assistance with linguistic difficulties; and there is a full vocabulary. There are full chapter headings in English enabling the reader to follow the narrative and easily select sections of most interest.
