'ancient general' is the definition.
The definition suggests a singular noun which matches the answer.

'experiences rout not quite fully' is the wordplay.
'experiences' becomes 'has' (have can mean to experience or go through).
'rout' becomes 'drub' (I've seen this in another clue).
'not quite' means to remove the last letter (most but not all of the word).
'fully' becomes 'all' (I've seen this in another clue).
'all' with its last letter removed is 'al'.
'has'+'drub'+'al'='HASDRUBAL'
