The other astonishing thing about the Poles in WWII is the routes they found to fight - from the ones who got out through Rumania (who ended up being reequipped and organised by the French before the German attack on France), to Anders' crowd, who were treated appallingly in the USSR before making their way South to the Levant, to those who stayed with the Russians and formed the Polish formations of the Red Army, it's an honourable and stirring story and the way the veterans were treated in the West not a story to our credit.First Polish Airborne should've jumped on Warsaw, but did Arnhem instead. 303 Polish Squadron the highest scoring in the Battle of Britain (having been commited late to the battle), Polish Carpathian Brigade fought at Narvik and in the defence of Tobruk. Second Polish Corps took Cassino and Ancona 1st Polish Armoured Div hammered the Germans at Falaise and ended up taking and garrisoning Wilhelmshaven. Polish Squadrons in Bomber Command helped bomb the "guwno" out of Germany. Polish Naval ships fought in the North Atlantic and the D-Day landings, etc. Polish resistance and intelligence network worked across occupied Europe including elements in France and French North Africa which aided Op Torch. Contribution to cracking Enigma and providing accurate intelligence on V weapons. Etc, etc.
Post WW2 demobilised Polish soldiers in the West were recruited and trained in the "Pogon" organisation to be dropped into Poland and coordinate anti-Soviet activity if WW3 kicked off. The program only tailed-off in the early sixties.
Moscow kept the Warsaw Pact Polish Armed Forces on a very short and tight leash as they did not trust them (rightly so). As far as Poland was concerned only one of its joint invaders of 1939 had been defeated the other one still needed tearing down.
The current Polish Armed Forces take the majority of their history and traditions from the Armed Forces of the Polish Second Republic of between the World Wars and the Polish Armed Forces of WW2.
Not enough people grasp, incidentally, just how patriotic and pragmatic Jaruzelski was when he declared martial law in Poland in December 1981. While that was unpleasant for the Polish people and the good folk of Solidarnosc, the alternative - a full-blown Soviet/Warsaw Pact invasion - was many times worse and would have happened before New Year 1981.
