Plot hole: Maria describes in lurid detail how Anna was arrested by the Germans and tortured by being severely whipped, leaving her with gruesome scars all over her back. She also says that Anna hasn't spoken a word to anyone since she escaped from captivity. How, then, does Maria (or anyone else) know about the scars? Nobody saw them (they don't exist) and Anna obviously didn't tell anyone about them.
Plot hole: Whilst on the surface a drifting ship is seen and an officer and two sailors are sent to check it. On deck the officer says check fore and aft. The sailor who goes to the right and out of sight is back in 5 seconds. This is not enough time to check his allocated section. The script should have shown the officer check his watch (dial visible) and say something like "you have got 15 minutes". Next shot to show the officer checking his watch again and we see 10 minutes have passed and the men return.
Plot hole: The Rangers arrive at the hideout when the lad following never got back to tell them where it was.
Suggested correction: She is probably able to write.
This correction is too speculative and offers no in-film evidence or further proof.

Anna was a school teacher.
Wasn't she a school teacher? So probably could write.
If she "wrote" about the scars wouldn't someone want to see them, perhaps get her to a doctor? Making up silly, deux ex machina explanations for film mistakes does not invalidate them.
Your assuming a lot like when the Germans release here. She could have "recovered" and had a fit anytime anyone touched her.
As was noted above, making up silly, deux ex machina explanations for film mistakes does not invalidate them. You cannot 'recover' from scars. It is ridiculous to think that nobody ever thought to get Anna to a doctor for treatment.
