Discussed naval base in appropriate port (6,4)

'discussed' is the definition.
('talk over' can be a synonym of 'discuss')

'naval base in appropriate port' is the wordplay.
I cannot really understand how this works, but
'base' could be 'e' (Euler's number - base of natural logarithms) and 'e' is found within the answer.
'port' could be 'dover' (English port) and 'dover' is present in the answer.
The remaining letters 'talk' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
