Now just let's get things straight.
The Enigma supplied by the Poles was an early version which none the less provided clear insight into how it operated. That alone was not enough to decrypt Enigma messages. You also needed to know various initial settings which changed on a frequent (daily) basis. The genius of BP was in building machines and procedures for recovering the settings on a regular basis.
The U110 recovery was of the more complex naval Enigma machine, significantly different from
that the Poles had in the 1930's. As well as recovering this machine, vital code books (giving initial settings) were also recovered from U110.
The Colossus proto-computers, of course, had nothing to do with Enigma.
Robert Harris's fictional account "Enigma" gives a good feel of BP and the cracking of Naval Enigma. The movie "Enigma" was, to me, a bit of a disappointment and why wasn't it shot on location at BP?
