Charge again presents terrible ordeal (6)
I believe the answer is:
reload
'charge again' is the definition.
('load' is an answer for 'charge' so perhaps 'reload' is OK for 'charge again')
'terrible ordeal' is the wordplay.
'terrible' indicates anagramming the letters.
'ordeal' anagrammed gives 'RELOAD'.
'presents' is the link.
(Other definitions for reload that I've seen before include "Put in another charge" , "Encumber again" , "Put more bullets in" , "Prepare to fire again" , "Ordeal (anag.)" .)
