La página que enlazas dice que el suceso tuvo lugar en mayo-junio de 1941. Realmente, desconozco la importancia que tuvo para la gente de Bletchley Park el material que se dice se encontró en el Lothringen. Lo que sé es que en esas fechas y antes, Bletchley Park ya estaba descifrando los mensajes de Enigma y que sólo se vieron en un verdadero brete a principios de 1942, cuando los alemanes añadieron un cuarto rotor a la máquina Enigma, lo que dejó en blanco a los británicos. En este punto el barco que entró en liza fue el HMS
Petard y el hundimiento del U-559 a finales de octubre de 1942 en la costa de Egipto. Fueron el marinero Colin Grazier y el teniente primera Tony Fasson quienes se lanzaron desnudos al mar para bucear y entrar en el U-559 que se hundía rápidamente para rescatar cualquier material de importancia que tuviera:
[With terrific bravery -clambering aboard a vessel that was obviously sinking fast- they managed to get down into the freezing darkness, then find and pass water-proofed Enigma codebooks back to canteen assistant Tommy Brown. But then, now knee-deep in water, they also tried to hault equipment out of that blackness - and they were suddenly too late to escape as the submarine finally plunged. They were taken with it. Their courageous action, however, was almost beyond value: those codebooks were the Short Weather Cipher and the Short Signal Book. It took just over three weeks to get them back to Bletchley. And instantly the codebreakers saw the treasure they had -these books in essence gave them an express route into unlocking the four-letter indicators, and thence each day's Enigma setting. Hut 8 got the books on 13 December 1942. Within just one hour of their first decrypts flowing through, intercepts of U-boat signals were sent through to the Admiralty, enabling them to instantly pinpoint the positions of fifteen U-boats. From that point on, an almost unquantifiable number of lives and vessels were saved as a result]. Sinclair McKay,
