I might write a review, but the short answer is that it was a book with a lot of promise at the start that quickly drowned in a litany of names, names with no depth, and a boring recitation of facts. I also found the capitalization choices odd - Nationalist was capitalized, but nazi wasn't, and Catalan was capitalized (so was Basque), but jew wasn't.

The author clearly tried to put too much information into the book to the detriment of anything resembling a compelling narrative. He also bore the pro-Republican (in the Spanish sense of the word) sympathies that many in the West had, so when Franco's falange executed people, it was a repressive bloodbath, but when Republicans murdered thousands of prisoners in Madrid ahead of a Nationalist offensive, it was "clearly a result of panic". How the author could think that communists were not capable of premeditated mass murder (yet noting that most of the Russian advisers to the Republic were executed in Stalinist purges) is baffling.

However, after finishing the book, I must say: ¡Viva Franco!
