Generally the protected side (3)

I believe the answer is:

lee

I'm a little stuck... Click here to teach me more about this clue!

'protected side' is the definition.
(I've seen this in another clue)

I can't explain the remainder of the clue.

(Other definitions for lee that I've seen before include "Robert E. - - , US hero" , "Confederate general" , "Protection" , "Bruce ___, martial arts ace" , "Revolutionary general" .)

I've seen this clue in the Evening Standard.
