Battle of Orleans all over the place (7)
I believe the answer is:
salerno
'battle' is the definition.
(I've seen this before)
'orleans all over the place' is the wordplay.
'all over the place' indicates anagramming the letters.
'orleans' is an anagram of 'SALERNO'.
'of' is the link.
(Other definitions for salerno that I've seen before include "Battle" , "Campanian port" , "South Italian port" , "European city!" , "in Italy!" .)
