The book provides an account of the genesis, growth, and deployment of the Tank Corps during the First World War, based largely on the author's personal experiences as a subaltern. The narrative traces the evolution of the armored landship from experimental designs and initial skepticism to its status as a revolutionary arm of the service that transformed infantry tactics and shortened the conflict.
The early chapters explore the Genesis of the Landship, detailing the efforts of the innovators who sought a mechanical answer to the triple obstruction of trenches, barbed wire, and machine-guns. It describes the early trials of tractors, the creation of the Heavy Section of the Machine Gun Corps, and the difficulties of command under a dual control before the establishment of the Tank Commission and the Ministry of Munitions.
The operational narrative follows the corps through its trial phase on the Somme, where forty-nine tanks made their first combat appearance in September nineteen sixteen. Despite mechanical breakdowns, bad weather, and a lack of preliminary coordination with the infantry, the new machines demonstrated a decisive moral effect and the capability to break strong positions at minimal cost.
Subsequent chapters follow the expansion of the corps into brigades and battalions and its deployment in the battles of Arras, the Palestine campaign at Gaza, and the opening stage of the Flanders offensive at Messines. Each operation is analyzed through the dual lens of tactical success and recurring obstacles such as adverse terrain, inadequate reconnaissance, and the conservative skepticism of senior officers.
A central theme of the work is the struggle of the Tank Corps to establish its independence and to demonstrate the validity of its tactical doctrines. The narrative shows how the long preliminary bombardment destroyed the terrain and defeated its own purpose, whereas surprise attacks led by concentrated masses of tanks offered an alternative that eventually permeated the entire army.
The account culminates in the transition toward the methods that achieved success at Cambrai and during the final advance of nineteen eighteen. Throughout, the text maintains a balance between the technical peculiarities of early tanks, such as Marks I and IV, and the human element of the crews who endured heat, noise, and constant danger.
