All
I have also read this book and can very much recommend it to everyone interested in what happened in April 1941 when Yugoslavia was invaded by the Germans.
The history is highly detailed (I have never seen a more detailed unit/day-by-day story from Yugoslavia before). There is a complete listing of aircraft and although I would have preferred some of the material to be collected in appendices than rather have it inside the book itself, it does not diminish their value.
Also Aleks should be congratulated for having taken the decision to publish his book in English, which of course makes it much more readable for most of us.
If the Blenheim is your cup of tea, buy the book. If you are fascinated by what happened back in 1941 on the Balkans, buy the book. I had great pleasure reading it.
Hats off Aleks

When do we get the Hurricane??
Cheers
