This is the fascinating and untold story of the 24 Eskadra of the Polish Air Force in September 1939. 24 Eskadra was the only unit during September 1939 which ended the Polish Campaign with the same number of aircraft as it started, despite heavy losses. The operations of the unit, its successes and losses, are described in detail in this book. Additionally, this was the sole unit which used the most modern liaison aircraft in Poland at the time, the LWS-3 Mewa. This new book is full of unpublished photographs of the Karas , the major reconnaissance and attack aircraft in Polish service, and of the Mewa.
