The best books for an insight as to why men go to war

This has to be one of–if not the–greatest single book I’ve ever read about war in the ancient world. I read the first ten pages, and I was interested; then I read the next forty, and I was utterly hooked. As a description of an elite military force holding out against overwhelming odds it fascinated me, but as a human story of the way Spartan society worked to produce those warriors, imbued with heroism, honour and humour in equal amounts I was simply blown away.

It’s fair to say that this book has been my greatest influence all the way through my writing career. I dare anyone with an interest in the genre to read this and then deny that they were informed, entertained, and (perhaps darkly) amused by the story and its payoff. This is God-tier writing, plain and simple, and, not for no reason, the closest thing the United States Marine Corps has to a fictional set text. 

O’Brien performed some sort of alchemy in turning a previously dry and underpopulated section of the historical fiction genre into literary gold, at once gripping and supremely well-written. One follows the adventures of a Royal Navy Commander and his Irish doctor friend–a man with a secret life–through the war at sea in the Napoleonic era, and I found the balance between naval exploits–Jack Aubrey being a swashbuckler of renown–and period history made for fascinating counter-points.

Over and above that, I loved the way O’Brien built an ensemble cast and proceeded to draw the reader into their lives, making the death of any one of them a personal loss. I know that I benefitted from learning this writing trick and used it myself in my Empire series, and I know at least one other Roman author who did much the same. Wonderful stories that kept me coming back, and this is the first book in a series I’ve re-read more than once.

The book starts off with the hero, Arimnestos of Platea, as the son of a farmer and ends with him, a cold-blooded and rational killer of men, proven in battle and with a terrible revenge yet to be taken. On one level, I found it to be a strong story taken from Greek history at the time of the Persian invasion, but I also marveled at the strength of Cameron’s characterization, his deeply detailed descriptions of war and battles, and most of all the undeniable fact that his re-enactment interest means that he knows just what it’s like to fight to the point of exhaustion in bronze armor or in a Greek phalanx.

By the end of this book, there was no choice. I was straight into the next, and this series is perhaps the strongest I’ve ever read on war in the ancient world, taking in Marathon, the naval battle at Salamis, and much besides. Anyone who loves to read about men at war who hasn’t yet had this pleasure has a massive treat in store.

I came across this book while researching why the US Army (and Marines) struggled so badly in the Vietnam War. As with all the books I’m recommending here, it spoke to me of how men go to war for their duty but stay at war for their brothers.

It speaks volumes of the frustrations and contradictions of a war in which an American generation skewed to the poor and racially discriminated against was sent to fight a highly motivated army of liberation and paid the price for their obedience. And told me more about what really happened in the valleys of that benighted country than any history book could.

I read it cover to cover and then read it again, eagerly consuming its truth at a time when the scars were so fresh that the truth was barely starting to emerge, and I commend it to you both as a clear signpost to the way that the Army had to–and did–rescue itself from the trap that VietNam had dropped it into and as a story for men at war and their love for each other that keeps them in the fight against all logic. Masterly.

If the other four books I’ve recommended are founded in grim reality, this one’s that guilty pleasure that an ancient world author might not want to be caught reading. But, if war is a timeless and undeniable fact of human existence—and it seems to be right now—then Marko Kloos’s story of men and women at war in the 22nd century, with an enigmatic alien species as the enemy, is pretty much timeless, too.

Yes, there’s a high-tech kit, but it’s never the McGuffin, and the same themes as ever—duty, honor, and the planet—come to the fore. Easy to read but never lazy, I found this series as gripping as the others. If you (like me) read a lot of historical fiction but have a soft spot for sci-fi, then this is about as highly recommended as they come.
