One side went (4)

I believe the answer is:

left

I believe this is a double definition.

'one side' is the first definition.
(left and right)

'went' is the second definition.
(as in leaving)

(Other definitions for left that I've seen before include "choice at a junction?" , "Sailed from" , "not consumed" , "Communist?" , "political grouping" .)

I've seen this clue in The Times.
