Guerrilla Warfare – Che Guevara

I have known of the existence of this book for many years and was somewhat confused that a book first published in the USA in 1961 and then in the UK by Pelican Books in 1969 was so elusive. I wanted it because I thought it would be a logical follow up of ‘The Motorcycle Diaries’ which I reviewed back in June 2022 and which very entertainingly covered a trip around South America by Guevara and his friend Alberto Granado whilst Guevara was studying to become a doctor. This book I assumed would cover his time as part of the Cuban revolution leading to his promotion as second in command below Fidel Castro and the ultimate overthrow of the Batista regime, But no I have since found out that a book I hadn’t previously heard of ‘Reminiscences of the Cuban Revolutionary War’, also written by Guevara and published in Pelican along with this book in 1969, performs that function. So what is ‘Guerrilla Warfare’ about? Well here we are probably coming to the reason it is so difficult to find, as it is basically a handbook on how to run a popular insurgency, from recruiting fighters to how to actually run a guerrilla band, feeding and clothing them, obtaining arms and proposed combat methodology. A look at the contents list gives an idea as to what to expect.

Despite not being what I expected the book is fascinating and gives an insight into the way a guerrilla band operates with some of the problems which come from operating in a secret way and some things that are different with a regular army. For example the chapters on warfare on favourable and unfavourable ground are diametrically opposite to a ‘normal’ army in that favourable ground for the guerrilla is the mountains and jungle where they can easily melt away or establish defensible positions whilst a regular army likes more open country where their heavy vehicles can move easily and this is precisely what a guerrilla army counts as unfavourable. Likewise armaments for a guerrilla fighter is largely restricted to rifles, preferably not fully automatic, and hand guns with homemade grenades or Molotov cocktails. The army on the other hand can utilise aircraft, tanks and tripod mounted machine guns which are too heavy to be easily moved by hand, which is usually how a guerrilla band would need to move them and quickly use far too much ammunition, which is always in short supply until they manage to capture more. Guevara explains that should a heavy machine gun be captured by all means use it but be prepared to abandon it if pressed as it is simply not worth the effort of carrying it away during combat. Guevara also says that a bazooka is an excellent guerrilla weapon let down by its size and the fact than a man can only just carry three shells any distance due to their weight and even then someone else has to carry the shoulder mounted launcher.

The need to capture ammunition also applies to most of the guns and rifles used by a guerrilla band, it is far easier to obtain these from the enemy than try to smuggle armaments in from outside, it also means that the ammunition is the same thus largely getting round the difficulties of supply. The section I have included below makes the distinction between a revolutionary and a terrorist in that a terrorist is indiscriminate in his targets unlike the more focused revolutionary. In another section Guevara also dismisses gangs of bandits as preying on the poor population whilst the revolutionary is there to support them, although he admits that the guerrillas will need food and clothing which the peasant agrarian economy must provide as they are the only practical source. But he explains that whenever possible this should be paid for either with cash or promissory notes which should be honoured as soon as possible. How likely this is to actually happen isn’t explained.

It should be pointed out that Guevara had a reputation as a ruthless fighter and unforgiving disciplinarian, executing deserters from his troops. But none of this is mentioned in this work which, whilst not glorifying Guevara as he isn’t mentioned by name, is more a guide on how to operate a revolutionary force at least in the context of 1950’s/60’s South American environment, which is almost certainly why it is no longer in print and copies are so difficult to come by. It was an unexpectedly interesting read and I have deliberately not included some of the more specific sections on armaments and tactics in this review.

Mathematical Games – Martin Gardner

This week I’m going to cover not one but five books, all of which started life as articles in Scientific American under the heading of Mathematical Games. This column was originated by Martin Gardner in 1956 and I first came across it in my school library in the early 1970’s and became hooked, looking forward to the next monthly issue, which fortunately the school subscribed to. Eventually Gardner compiled fourteen books based on the column, five of which I own.

The first book has an unfolded flexagon alongside a mobius strip and immediately highlights the cover design issues with the Pelican editions in that although flexagons are the subject of the first chapter, the curious single-sided mobius strip is not referenced in this book. Flexagons were in fact the subject of the very first article Gardner wrote for Scientific American and are constructed by folding a strip of paper in a triangular pattern until you create a hexagon which when manipulated, or flexed, opens out and then returns to a hexagon shape but with different sides displayed. So if the user had coloured the original two visible sides these would disappear and new blank faces appear. It is possible to create flexagons with large numbers of faces but the number is always divisible by three. The book describes how to make a couple of different variations and I remember having great fun playing with them. Other chapters include the mathematical game of Hex, an overview of the puzzles created by American Sam Loyd, card tricks (Gardner was a keen magician as well as mathematics writer) and random collections of short puzzles which would be a staple of Mathematical Games columns and their successors in Scientific American.

The second book has a cover that is entirely from the imagination of the designer, in this case Denise York, as it has nothing to do with anything in the book which does however have an article about the five platonic solids one of which this definitely isn’t. Again we have an article about a great historical puzzle maker in this case the English near contemporary of Sam Loyd, Henry Ernest Dudeney, there are also discussions of three dimensional tangrams, magic squares, recreational topology and even origami. Like all the books I have each chapter is reprinted in the book and an addendum is added covering items that were raised after the publication of each column, sometimes pointing out things that were incorrect. Gardner surprisingly wasn’t a mathematician, or an academic, he was just fascinated by mathematical puzzles. Two of the people that continued the mathematics column in Scientific American after he retired in 1979 were professors Douglas Hafstadter and Ian Stewart.

The first two books were published by Pelican in the mid 1960’s but the next time they printed one of Gardner’s books was another pair, this time in 1977 and 1978. Again the the covers are not relevant to the text with the ancient puzzle of the Tower of Hanoi on the cover of Further Mathematical Diversions although this was in fact covered in the first book ‘Mathematical Puzzles and Diversions’ but this third Pelican title does have some of my favourite columns in it starting with the paradox of the unexpected hanging where the judge pronounces on the Saturday of the judgement that:

The hanging will take place at noon, on of of the seven days of next week but you will not know which day it is until you are informed on the morning of the day of the hanging.

The prisoner is despondent but his lawyer is pleased as he reasons that the sentence cannot be carried out because he cannot be executed on the Saturday as that is the last possible day and therefore he would know on the Friday that he was to be executed that day. Likewise it can’t be the Friday as Saturday is impossible so Friday is the last day and so on working back through the week. The logic is fine and worked right up until Thursday when the man was unexpectedly hung. The discussion on why the logic fails is quite entertaining.

Also in this book are articles on the transcendental number e, the properties of rotations and reflections, gambling, chessboard problems and numerous other subjects including the inevitable sets of nine short problems, but my favourite, because it prompted me to attempt to build one was about a ‘computer’ built of matchboxes and beads which could ‘play’ noughts and crosses (ticktacktoe) in fact the original article that this chapter was based on first appeared in Penguin Science Survey, a publication I was unaware of at the time I first read this article. The machine is more of a simple learning machine than a true computer but using three hundred matchboxes it is possible to have something that gradually optimises how to play the game and in the example described it was winning, or at least not losing the majority of games after just twenty goes.

The fourth book again doesn’t seem to have anything to do with the cover illustration but does have various articles including Pascal’s Triangle, infinities that are bigger than other infinities, the art of Dutch artist M.C. Escher, random numbers and a ‘simple’ proof that it is impossible to trisect an angle using just a compass and ruler although bisection is extremely easy. There are again many other subjects covered although unlike the other volumes there isn’t a chapter of nine short puzzles. I remember being fascinated by aleph-null and aleph-one infinities when I first read this piece as a teenager, the concept of ‘countable’ and ‘uncountable’ series resulting in differing ‘sizes’ of infinities was so different to what I was being taught in mathematics at the time that I needed to read it a couple of times to get my head around what was being explained and I have of course come to love the art of M.C. Escher.

The final book I have by Gardner is a hardback published by Allen Lane rather than paperback Pelicans although both are imprints of Penguin Books. It follows much the same format as the other four with twenty chapters based on articles from Scientific American but this time I don’t remember reading many of these before but topics include such diverse subjects as Fibonacci and cyclic numbers, the Turing test, devised by Alan Turing to determine if a machine could fool a human into believing they were conversing with another human. The smallest cyclic number is one that I have always remembered and it is 142,857, what makes it cyclic well just multiply it by 1 to 6 and see that the digits remain in the same order just starting from a different place i.e.

  • 142857 x 1 = 142857
  • 142857 x 2 = 285714
  • 142857 x 3 = 428571
  • 142857 x 4 = 571428
  • 142857 x 5 = 714285
  • 142857 x 6 = 857142

I’ve thoroughly enjoyed the mental workout reading these books again this week and remembering oddities of mathematics that have stuck with me since my teenage years and if you have any liking for puzzles I heartily recommend searching out Martin Gardner’s extensive output.

A.S.B. Glover – Tim Graham

Subtitled ‘The Unacknowledged Genius of Penguin’ this is part biography and part a collection of correspondence and it is the letters both to and from Glover that give the clearest picture of the character of the man. For those people not familiar with the name A.S.B. Glover, which I suspect is most of the people reading this blog, he was responsible for proof reading and editing several series for Penguin Books over a period of sixteen years especially the factual Pelicans as well as editing various books for other publishers. This was a role that ideally suited this remarkably erudite man who could read and write in multiple languages including Ancient Greek, Latin and Sanskrit and was also a renowned scholar in religious texts and the saints of the various Christian denominations and yet left school with no qualifications. Biographical details regarding Glover are difficult to find, he was born in 1895 as Alan McDougall and changed his name sometime in the 1920’s possibly due to his regular imprisonment during World War I as a conscientious objector under his original name. One thing that I definitely didn’t know about him that Tim mentions is that his body was covered in tattoos, including his face, although these facial ones were later removed leaving some scarring and that he may have earned a living for a time as a tattooed man in circuses. Tim cannot find any evidence of a McDougall or Glover working in such a role but it is entirely possible that he had yet another name that he worked under at the time.

He first came to the attention of the publishing world by sending numerous letters containing corrections to books they had recently published to the extent that Penguin realised that it would probably be cheaper to employ Glover to catch mistakes before they went to print rather than amend books for subsequent publication. I’ve mentioned before that you see more of Glover in his letters and the following example dealing with a matter close to his heart after his years in prison is a case in point.

The book by Trevor Gibbens never saw light of day despite Glover’s repeated attempts to get the author to finish it.

This book however is published in a limited run of just 600 copies by The Penguin Collectors Society and designed to look like a Pelican from the period Glover was in charge. At the time of writing this review it is available from the society for £12 plus postage, follow this link if interested. All in all it is an really good book about a fascinating man, who although he didn’t get on all the time with his colleagues and particularly not his boss, Allan Lane, was nevertheless essential to the accuracy and therefore the authority that Pelican Books established under his control.
