About to engage in assault after line's encouragement to attack
I believe the answer is:
battle cry
'attack' is the definition.
Both the definition and answer are singular nouns.
Perhaps you can see a link between them that I don't see?
'about to engage in assault after line's encouragement' is the wordplay.
I cannot really see how this works, but
'about' could be 'c' (abbreviation for 'circa') and 'c' is found in the answer.
'line' could be 'battle' (battle line is a kind of line) and 'battle' is present in the answer.
This explanation may well be incorrect...
'to' acts as a link.
Can you help me to learn more?
(Other definitions for battle cry that I've seen before include "Slogan (for those going into a fight?)" , "Geronimo, for example" , "Martial slogan" , "jingoistic shout" .)
