Excellent  1939 On 1 September 1939, at the beginning of the invasion of Poland, all the Polish combat aircraft had been dispersed to secondary airfields, contrary to a commonly-held belief, based on German propaganda, that they had all been destroyed by bombing at their airbases. The aircraft destroyed by German bombers on the airfields were mostly trainers. The fighters were grouped into 15 escadres; five of them constituted the Pursuit Brigade, deployed in the Warsaw area. Despite being obsolete, Polish PZL-11 fighters shot down over 170 German aircraft. The bombers, grouped in nine escadres of the Bomber Brigade, attacked armoured ground columns but suffered heavy losses. Seven reconnaissance- and 12 observation escadres, deployed to particular armies, were used primarily for reconnaissance. Part of the Polish Air Force was destroyed in the campaign; the surviving aircraft were either captured or withdrawn to Romania, Hungary, Lithuania, Latvia, Slovenia or Sweden, whose air forces subsequently employed these aircraft for their own use (in the case of Romania until 1956).  A great number of pilots and aircrew managed to escape to France and then to Britain, where they played a significant part in the defence of the United Kingdom against Nazi invasion, during the Battle of Britain. Prior to the conflict Poland also bought 234 planes abroad. First of them were on delivery when the conflict started. These were Hawker Hurricane (14 planes), Morane-Saulnier 406 (120 planes) and Fairey Battle (100 planes). The ship SS Lassell with 14 Hawker Hurricanes on board left Liverpool on 28 August 1939, deliveries from France were also on way when the conflict broke out.1940 (France)After the fall of Poland, the Polish Air Force started to regroup in France. The only complete unit created before the German attack on France was the GC I/145 fighter squadron, flying Caudron C.714 light fighters. It was the only unit operating the C.714 at the time. The Polish pilots were also deployed to various French squadrons, flying on all types of French fighters, but mostly on the MS-406. After the surrender of France, many of these pilots managed to escape to Britain to continue the fight against the Luftwaffe.
