you made it very poorly, in my opinion. I would dispute it even as you state it here as well - the UK, as part of the allies, clearly won the war. As a nation the UK achieved both the aim of removing German occupation from Poland which had brought them into the war and also the underpinning reason of limiting Germany and restoring the balance of power in Europe, a centuries old aim. That all this was at such a massive cost and speeded up the loss of Great Power status wasn't avoidable, not going to war would have been at a far greater cost - which if one wants to look beyond the the stated reason and the underlying reason would also be a win.



Common usage of "decisive" very much includes "crucial" and that is exactly what the Poles work on the Enigma machine was - without them managing to solve the problem of how the German military Enigma machine differed from the "public" version their codes would probably never have been cracked. Of course you seem concentrated on their breaking of cyphers, which is a pretty minor contribution compared to their major contribution but you seem to only be talking about the latter - that does suggest you are either unaware of what they actually did or don't understand it.



It was "a" decisive contribution - not "the" decisive contribution. The work they did was a key part of the war effort against Germany and it enabled much other effort against Germany.



That might be but the Soviets did have significant Allied aid and would have struggled far more with out it - they received of tanks, trucks, artillery guns and aircraft... and copied the designs of them to update their somewhat antiqued designs, as well as tonnes of food that "powered" the Soviet's industrial production. So they might have been able to do it alone but they actually did it with massive Allied aid... which as imperfectly as the information obtained from the cracking of Enigma was obtained, it helped greatly with.



Germany was getting, if I recall correctly, 4 million barrels a year from the Soviets and this wasn't enough, hence Operation Barbarossa which was fuelled by using up most of Germany's oil reserves. By '42 massive efforts were being made to convert vehicles to run on wood and it was basically policy to supply no one, not even the military, with the full amount of fuel they needed. Hitler had enough fuel to do what he did, not enough to do what he wanted to do... which is a massive difference



It is a poor article, I will agree on that and the only thing that can be said for Poland's efforts on the field of battle is that they were brave. Sadly for the brave Polish military, they were fighting a modern military with modern (too modern for the British Army, doh!) military tactics while they had WWI equipment and tactics.
