GDG- Twentieth Maine's Right Flank

[James Cameron]

<< Any idea why the 20th's right flank marker is where it is, or is this 
another case of a veteran guessing where their right flank was, 25 years 
after the fact?  >>

Flank markers are, on the whole, almost useless in so far as marking where 
units' flanks actually were.   Trying to make sense of some of them can be 
an exercise in futility.
