Read my post more thoroughly before you mess up more. Don't take things out of context...bad form.
Not much context needed. As written, it is an historically false statement: and he like Donald Rumsfeld, resigned during war.
The truth is, Patton didn't resign during any war.
You might try referencing legitimate historical sources, rather than fan sites.
For example, for the American response to the German offensive in the Ardennes, see the material starting at page 332 here:
http://www.army.mil/cmh-pg/books/wwii/7-8/7-8_15.htm
and compare it to the version you learned from the movie.
