No ref's, but it seems unlikely - they could more easily have used EM
techniques on the cables.
If they were over the repeaters though, those had relays, whose clicking
could perhaps have been detected acoustically.
I find it curious that the Germans didn't cut the transatlantic cables
though - they knew where they were. Perhaps they didn't want to cut off
an intelligence source?
The British (and Germans) both cut most of the UK-continent cables,
though I have heard the British left one from Ireland, as they were
reading the traffic.
