The book unfolds by first introducing established military doctrines at the war's outset, such as linear formations and massed infantry assaults. It then analyzes how technological advancements disrupted these traditional tactics, detailing specific battles where new technologies rendered old strategies obsolete. Finally, the book investigates adaptive strategies developed by both sides, including trench warfare and the use of skirmishers, culminating in an assessment of the long-term implications of these changes on future military doctrine and warfare.
