A well-written book for people who want to know something about the war in Spain but who don't want a biased viewpoint or a harrowing book. The author is a Communist but makes no attempt to inspire volunteers. He writes of the routine of war and not its heroism; there are no romantic adventures and little dramatization of horror. Without emotionalism, he demonstrates that he goes to war to save issues which are ""significant for ourselves and the whole world"", in a ""conflict that must decide whether the enormous new powers that science has given the human race are to be used for the organization of decay or for life, for a mechanized barbarism or an advance of the human spirit."" He reports his experiences with no dramatics and little emotion.
