:Mr. Red Slayer, from what you said above, I would label this battle as a tactical and strategic Union vicotory.  However, for whatever reason, we seem to be in the minority.  The way battles are summarized for the American Civil War are inconsistant, and there is no hard and fast rule on how battles are to be summarized.  That is why I suggested that tactical, decisive, and strategic victories be rigorously defined somewhere in Wikipedia.   

 :Finally, for every other major war convered on Wikipedia (that I'm aware of), such as WW 1, WW2, Napoleonic Wars, etc., there is no compunction about using terms such as decisive and strategic.  Why this is not the case in the ACW, I have no idea.  But like I said before, battles for the ACW should be defined in one of two ways. 

 ::1) Use only Union/Confederate victory or indecisived/draw, or; 
 ::2) Use tactical, decisive, strategic, and indecisive/draw terminolgy 

 :I don't particularly care which method is used as long as it is consistent and well defined.  Anyway, that's my $0.02.
