Holed up in Manitoba, two Menshevik officers’ attendants (8)

I believe the answer is:

batwomen

'officers' attendants' is the definition.
(batman or batwoman can mean a military servant)

'holed up in manitoba two menshevik' is the wordplay.
'holed up in' indicates a hidden word.
'BATWOMEN' is hidden in the letters of 'manitoba two menshevik'.

I've seen this clue in The Times.
