A phenomenal autobiography that clearly portrays (1) the conflict between the Irish and British, (2) the true chaos of grass roots guerilla warfare, (3) the indicators that a superior fighting force is losing its control, and (4) the complete separation of the military (IRA) and the politicians (Sein Finn). This would be a great required reading at military academies.
First, the author clearly presents major players at multiple periods of conflict. The early Irish Volunteers are shown to be unorganized, unfunded, and not supported by local Irish. The early British forces are shown to be a de facto authority with control over arms, the press, and law enforcement.
Second, the author clearly presents the grass roots fighting of uncoordinated individuals, the author being one of them. He tells of a raid, of killing police officers, of being wounded, and going into hiding for weeks or months. This pattern repeats itself from the beginning of open conflict (1918), through the ousting of the British, and finally into Irish Civil War (1922). It is truly fascinating to see the author recount so many parallel stories, the absolute shift of a culture from peace to conflict.
Third, in military terms, the author does the best job I have ever seen describing the transition from conflict in a non-permissive environment to a permission environment. The guerillas in the beginning had no money, couldn't use cars on roads, had to hide in the wilderness, controlled no roads, etc. As the years go on the author points to transitions of each. The British shut down small police barracks as they were too dangerous, marshall law was established in more and more places, the press began condemning police actions (torture, murder, unlawful search and seizure, etc.), and finally IRA units moving freely in daylight.
Fourth, the author repeatedly states that the military violence was never supported publicly by the Irish politicians and even in private few were willing to get mixed up with those conducting guerilla warfare. The author shows his disdain for these politicians. He eventually supports the politicians publicly in and effort to prevent Irish Civil War, which failed. During the Civil War, he was captured and imprisoned for two months by his own countrymen.
It is difficult not so side with the man and his beliefs.
