In the third and final book which he wrote about his campaigns in the Civil War, Caesar tells the story of his fight with Pompey in 48 B.C. which ended in the rout of the latter at Pharsalus, perhaps Caesar's most notable military victory. The book ends with Caesar pursuing Pompey to Egypt. Here began Caesar's celebrated affair with Cleopatra. At this point the book, and the whole work, ends abruptly.With this volume the author's edition and commentary on Caesar's Civil War becomes the first complete commentary in English for a hundred years and is considerably more detailed than currently available annotated texts and translations in other languages. The main emphasis of the commentary, as before, is historical, but Caesar's literary technique is also scrutinised. The Latin text is newly constituted with a brief apparatus criticus. Latin text with facing-page translation, introduction and commentary.
