Which Bible writer was a General?

General: The role Joshua played in leading the army as the Israelites moved into the Promised Land and battled against many enemy peoples qualifies him as a general. (Joshua 1:1-3; 11:5, 6) He was privileged to write the book of Joshua. Then, too, some Bible readers may view David as a man who functioned as a general before he became a king.—1 Samuel 19:8; 23:1-5.

Are you insinuating that any authorship could be proven? Or are you asking which book has been rumored to be written by a general?

And by general, do you mean in the same way that jesus has been called a general because it is required by prophesy or a real general?
