What can we learn from warfare in the 20th century? This book looks at the strategy, the campaigns, the tactics, the people and the technology. The Hall of Mirrors is not a narrative history. It takes a deep look at war, and warfare, in the 20th Century. It looks at the strategy, the operational art, and the tactics. It looks at how technology was developed and affected military events. It looks at the human beings, the human organisations, and how they affected events. It makes judgements and comes to conclusions. By 1919 the First World War was already over. Those millions had died; those empires had crumbled; those new nations had been born. Nothing similar has happened, thus far, in the 21st century. All the more reason to look back and consider what did happen, and what we might learn from war and warfare in the 20th century.
