Mount charge again (8)
I believe the answer is:
rushmore
'mount' is the definition.
(I've seen this before)
'charge again' is the wordplay.
'charge' becomes 'rush' (I've seen this before).
'again' becomes 'more' (I've seen this in other clues).
'rush'+'more'='RUSHMORE'
(Other definitions for rushmore that I've seen before include "Mountain with carvings of US presidents" , "Mount with presidential statuary" , "Carved South Dakota Mount" , "Mount . . . . . . . . in USA has giant carvings of presidents" , "US mountain with carved heads of presidents" .)
