As fate would have it, Bert along with the rest of the crew of Unbeaten never returned from the submarines last clandestine patrol.
The author is very grateful to Derek Bayne, Bert's brother, for all the contributions he has made towards the book. Derek's input has added greatly to the historical accuracy of the story of Unbeaten and her crew.
Below is a very recent post left by Derek Bayne about 'Being Silent They Speak.
'Only a Submariner who has undertaken hazardous patrols in
a theatre of war can understand the pressure and restrictions that are imposed on members of the crew. Being Silent They Speak gives the reader the opportunity to experience the atmosphere aboard HMS/M Unbeaten'
