The Matabele Campaign [EPUB ebook] 

The following pages contain sketches of two kinds, namely, sketches written and sketches drawn. They were taken on the spot during the recent campaign in Matabeleland and Mashonaland, and give a representation of such part of the operations as I myself saw.
They were jotted down but roughly, at odd hours, often when one was more fit for sleeping than for writing, or in places where proper drawing materials were not available—I would ask you, therefore, to look leniently upon their many faults.
