A detailed contemporary account of wartime mobilization that follows recruits through cantonments and training grounds as they learn drill, signaling, gunnery, engineering, and logistical work. It profiles varied units — regional battalions, Territorials, colonial contingents and Indian troops — while explaining artillery, supply, transport and mechanical support, and noting kit, routines, and camp life. Observational vignettes emphasize the eagerness, innocence, and adaptability of novices, the instructors' methods, and the practical humor and discipline that shape them into serviceable formations. The text blends technical description with human detail to show how raw material is turned into an organized army.
