I run on coffee (aspectus)

Let us take a typical day with the gunners. Photographs or cinematographs are entirely unsatisfactory in giving any idea of the "movement" of a battery going into action. There is the rattle of the gun-carriages, like a running accompaniment of rifle fire; the jingle of the harness; the splendid, strenuous, willing pull of the horses straining against their collars. They know all about it, these bright-eyed beasts quivering with life and work, and want no whip or spur until the work of tugging over the broken ground under a sweltering sun staggers them under the strain.
