Summarised - engineers gave in (13)

I believe the answer is:

recapitulated

'summarised' is the definition.
(recapitulating is a kind of summarizing)

'engineers gave in' is the wordplay.
'engineers' becomes 're' (Royal Engineers).
'gave in' becomes 'capitulated' (I've seen this before).
're'+'capitulated'='RECAPITULATED'

I've seen this clue in The Daily Express.
