Boat handling and orders given were very inaccurate, four torpedoes fired out of the two forward starboard tubes in the space of 5 minutes.
Capt took charge for the attack with no briefing on current tactical situation.
Periscope on seemed to be left up at all times, no sign of U Boat snorting but diesel engines were running.
I suspect they used Jeff's A boat and were not prepared to pay enough to restore outside telemotor power and get the scope of the pins. As to the dialogue, it wasn't supposed to be a second by second account of the engagement and the interviews with the NO indicated there was in fact a fair ammount of briefing and discussion.
Knowing Jeff I am sure that he gave them chapter and verse and they then excercised their editorial authority and made what they thought was the best they could do for the cash and to satisfy the viewing public.
The non snorting U boat with diesels running was a strange bit, I will have to ask Jeff if I find an excuse to visit him again.
Even as a non submariner I noticed a lot of inaccuracies, also I found the presentation boring. On top of that I can't stand docu-dramas. It seems to me that they would rather keep rubbish actors in work than to take the trouble I searching the archives I find accurate footage. I switched off after 20 minutes and went to bed. Sad old git aren't I?
