This book was written by a Cretan peasant who acted as a courier for the insurgent or resistant forces on that island during the Second World War. One of his British officers, trying to organize and use the irregular or guerrilla bands on the island during that period, was Patrick Leigh Fermor, who wrote the long and very elucidating Introduction to this work. Leigh Fermor was also the famous character in Ill Met By Moonlight, dealing with his own experiences at the time (e.g. kidnapping the German commanding general on the island). The book was filmed in the 1950's under the same name and can be recommended as a fair view of some of what happened in Crete at the time.
As the Introduction explains, Crete is 160 miles long and betwen 20 and 40 miles wide. That would seem to make it an unsuitable place for irregular warfare, but the topography of the island leads to a different view. The mountains which covr much of Crete are often over 7,000 feet high and in places over 8,000 feet. This and the fact that, at the time, the only trans-island road was the North coast East-West route, meant that Crete was in fact ideal guerrilla territory, all the more so in a day when helicopters, drones, satellites and high-altitude spy planes etc were unknown.
Crete had been occupied by Allied forces early in the war, but fell to German parachute forces under General Student. The Allied forces then were either killed, captured or escaped to Egypt. Thus the irregular formations. The war in Crete betwen the Cretan irregulars and their German opponents was harsh in the extreme, with little quarter given on either side. That is the backdrop to this book.
The author covered all or most of Crete, on foot, in all weathers, carrying his messages and connecting from time to time with the resistant forces. He was also extracted at one time during the war and visited Egypt and Palestine. I found those parts of the book among the most interesting, not least his visit to Palestine which, after Egypt he found a paradise of lemons and oranges etc. This is the land which we are told was a "desert", only blooming after it had become "Israel" after 1948...
I was interested to read (in the introduction and notes) that the insurgent fores on Crete, being mainly non-Communist, were not so riven with internal dissent and backstabbing as those of mainland Greece and the Balkans generally. Also, the author does indicate that there was not only self-interested pro-German collaboration on the island, but that some islanders were "Germanophile". One has to remember that Crete had been part of both the Venetian and Ottoman empires. There may have been a rift between the isolated rural peasantry (who supplied the fighters of the insurgent forces) and the town-based folk, more educated, perhaps more likely to compromise with a de facto power. Two of the several pro-Germans killed in the book were medical doctors.
I should say that, as a firsthand account of the Second World War, pretending to nothing more than a simple country person's immediate view, without guile, it is well worth reading.
