...afterwards deployed in Southend! (4)

I believe the answer is:

then

'afterwards' is the definition.
(I've seen this before)

'deployed in southend' is the wordplay.
'deployed in' indicates a hidden word.
'THEN' is hidden within 'southend'.

(Other definitions for then that I've seen before include "Afterwards - as a result" , "Once upon a time" , "Subsequently - previously" , "soon?" , "Consequently" .)

I've seen this clue in The Irish Times.
