The Poles built a simpler machine that they called a "Bomba", a pre-cursor to the Bombes. Named for a dessert in a cafe near the Polish intelligence service offices where those early codebreakers worked, and because the French also received the intelligence from Poland, they transposed the name. :-)

In July 1939 the Poles had to hand everything over to the British because they knew it was all about to be lost, as they were months away from being invaded.

Unfortunately what the Polish handed over was not quite enough to break German naval enigma, and without that, the war would have been at worst lost, and at best lengthened by years.

The Poles got everything started. The Brits got it finished.

There were several other British innovations in code-breaking around the war time period though, including Tunny, and taken on aggregate it's clear Bletchley had a significant advantage in that space over every other country for a long, long time.

That of course does not excuse a demand for Apple's ADP to be back-doored.
