Imprison a lot of sailors dodging bloodbath (4)

I believe the answer is:
cage
'imprison' is the definition.
(I've seen this in another clue)
'a lot of sailors dodging bloodbath' is the wordplay.
I cannot really see how this works, but
'a' is present in the answer.
'lot' could be 'c' and 'c' is found in the answer.
The remaining letters 'ge' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for cage that I've seen before include "Pen" , "Eg, aviary" , "Incarcerate" , "Place of confinement" , "Barred container" .)
