Valiant to the last - the history of No.221 Squadron "The Valiants". While the book may be good at other aspects - I have read a chapter about the 90s which was quite good. It was quite disappointing as far as the 71 War History was concerned. There wasnt much - most of it borrowed from Air Chief Marshal Lal's book.
At the risk of being accused of blowing my own trumpet, my forthcoming book on the Bangladesh Air War will have more information on the Squadron ops than the Squadron;s official history.
