Major steps taken by one of those prior to the Battle of Charleston presumably
I believe the answer is:
war dance
'taken by one of those prior to the battle of charleston presumably' is the definition.
I can't judge whether this definition defines the answer.
'major steps' is the wordplay.
'major' becomes 'war' (I can't justify this - if you can you should give a lot more credence to this answer).
'steps' becomes 'dance' ('dance step' can be a synonym of 'step').
'war'+'dance'='WAR-DANCE'
Can you help me to learn more?
(Other definitions for war dance that I've seen before include "Pre-battle ceremony" , "Tribal ceremony before battle" , "Steps taken by fighters" , "steps taken before engagement" , "moves anticipating conflict?" .)
