Composer gets over a setting of part of War and Peace (8)

I believe the answer is:

borodino

I'm a little stuck... Click here to teach me more about this clue!

'a setting of part of war and peace' is the definition.
I can't tell whether this defines the answer.

'composer gets over' is the wordplay.
'composer' becomes 'Borodin' (Alexander Borodin was a Russian composer).
'gets over' becomes 'o' (I've seen this in other clues).
'borodin'+'o'='BORODINO'

Can you help me to learn more?

(Other definitions for borodino that I've seen before include "Napoleon 1812 victory near Moscow" , "Battle of eighteen twelve" .)

I've seen this clue in The Times.
