Stephen Turnbull's The Samurai Invasion of Korea 1592-98 is part of the Osprey Campaign series. Like in most other Turnbull's books, this book proves to be well written, clearly explained and well researched about a subject matter that very few Americans would have any inking about.
The book basically summarized the Japanese invasion of Kingdom of Korea during the 1590s. This was Japan's only act of aggression against a foreign nation until the modern period. The book followed the typical Osprey Campaign model, giving the background, commanders and unit types before hitting the ground running with very nice narrative of the seven year campaign of Taiko Toyotomi Hideyoshi's efforts to rule eastern Asia. I thought the maps, drawings and photographs inserted into this book were quite good and very helpful.
Interestingly, the author often points out his other books that he has written for Osprey to tell the readers that if they wanted to know more, then read this book or that depending on the subject matter pertaining to the war.
If there is a pitfall in this book, this book is basically a shorter version of Turnbull's earlier work, Samurai Invasion that came out in 2004. The author's claims that in this current book, he gave a more balance account of the war. Having read the older book first before reading this book, amount of balance don't seem to justified getting this book if you owned the older book already.
It is also interesting that Stephen Turnbull failed to give some realistic reasons for the cause of this war. He apparently believed that this war was a result of Toyotomi Hideyoshi's megalomaniac dream of an Asian Empire or something that seem more out of some historical TV drama then real history.
But overall, this is a fine book about a subject matter little known to most Americans and Turnbull's gives clarity to the campaign that well reflects his expert knowledge of Japanese history. It is interesting to note that this campaign foretold the collapse of the two major powers that fought so hard over Korea, Ming Dynasty that fell to the Manchus while Toyotomi family that fell to the Tokugawa family.
