GDG- Habeus Corpus question

[NickRELee at aol.com]

Basically it means produce the body, I'm sure someone will provide a better  
latin interpretation, but thats the rough meaning.  Bervinus was probably  
underage, nearly every time I've seen this notation it was because the soldier's  
parents showed up and wanted their young son back home.

One of the people I am researching,  Bervinus Townsend of the 16th Michigan
(V Corps, 1st Div, 3rd Bde) is  listed in the records as:

"...discharged for by writ of Habeas  Corpus..."

What does this mean?
