What is the author's style in The Jugurthine War by Sallust?

Sallust starts both books by setting out a plan for his argument. This shows how he has divided the chapters. For example, the first five chapters of the Conspiracy of Catiline cover the introduction, and the next five chapters follows the virtues of Ancient Rome. The chapters tend to be very short, three paragraphs at the most, unless there is a speech, which usually fills two or three pages. The more a section continues, the less Sallust looks at it from a historical perspective, and the chapters become shorter and more action based. As such, the stories move along quickly and read more like a novel than an historical document. Sometimes Sallust places a speech in the text from a Roman, for example Julius Caesar. This tends to work to get Sallust's view across and add credence to the battle scenes. However, in general, Sallust sets out the course of the book and his own view from the very beginning, and then within this perspective, he tells the story.
