Audley End House in Essex - or Station 43 as it was known during the Second World War - was used as the principal training school for SOE's Polish Section between 1942 and 1944. Polish agents at the stately home undertook a series of arduous training courses in guerilla warfare before being parachuted into occupied Europe. In 1943, Audley End was placed exclusively under polish control, a situation unique within SOE. The training was tough and the success rate low, but a total of 527 agents passed through Audley End between 1942 and 1944. Ian Valentine has consulted a wide range of primary sources and interviewed Polish instructors and former agents who trained at Audley End to write the definitive account of this Essex country house and the vital but secret part it played in defeating Hitler. He examines the comprehensive training agents at Audley End and describes the work undertaken by Station 43's agents in Europe, set against the background of Polish wartime history. He also covers the vital link with the RAF's Special Duties squadrons, whose crews risked their lives dropping agents into occupied Europe. Station 43 breaks new ground in telling the hitherto until story of Audley End house and its role as a vital SOE training school.
