Second victory against England finally? The French cheat! (7)
I believe the answer is:
swindle
'cheat' is the definition.
(both can mean to defraud or deceive)
'second victory against england finally? the french' is the wordplay.
'second' becomes 's' (common abbreviation).
'victory' becomes 'win' (a win is a victory).
'against' says to put letters next to each other.
'england finally?' becomes 'd' (I am not sure about this - if you are sure you should believe this answer much more).
'the french' becomes 'le' ('the' in French).
's'+'win'+'d'+'le'='SWINDLE'
Can you help me to learn more?
(Other definitions for swindle that I've seen before include "Ramp" , "Trick" , "fleece" , "Cheat; fraud" , "Scam" .)
