Zamoyski combines the facts with personal records to create a real and human picture of the Polish airforce in Great Britain during ww2. From the bit that I know he gets it exactly right, especially with regard to the loathsome post war trades union / intellectual "scientific" socialist / communist sympathisers, agitating for the expulsion of Poles from the U.K. As a matter of record, the post war labour government of Clement Atlee also excluded the Poles from the June 1946 London Victory parade to avoid offending Stalin and his pro communist labour supporters, and the Battle of Britain monument ,erected at Dover in 1993, commemorated every squadron that took part except two. Neither the (Polish) 302 nor 303, the highest scorer of the lot , is mentioned. This book is just as well written and interesting as Zamoyski's much better known, "1812: Napoleon's Fatal March on Moscow".
