I believe the answer is:

garibaldi

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

'general' is the definition.
(Giuseppe Garibaldi)

I cannot understand how the remainder of the clue works.

(Other definitions for garibaldi that I've seen before include "Italian hero, who led his 'Thousand Redshirts' against the Austrians, d. 1882" , "Currant biscuit - Italian patriot" , "Lady's blouse" , "Revolutionary leader" , "leader of nationalists" .)

I've seen this clue in The Telegraph.
