Came to and read about a revolutionary (7)
I believe the answer is:
reached
'came to' is the definition.
(to come to is to reach or arrive at)
'read about a revolutionary' is the wordplay.
'about' is an insertion indicator.
'a revolutionary' becomes 'che' (Che Guevara the Marxist revolutionary).
'read' going around 'che' is 'REACHED'.
'and' is the link.
(Other definitions for reached that I've seen before include "Stretched or arrived" , "Cad here (anag.)" , "Attained" , "Came to (a place)" .)
