Some Americans were drafted, and responded (8)
I believe the answer is:
answered
'responded' is the definition.
('answer' can be a synonym of 'respond')
'some americans were drafted' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'ANSWERED' is hidden within 'americans were drafted'.
'and' is the link.
(Other definitions for answered that I've seen before include "Satisfied" , "Fulfilled" , "was sufficient" , "Came back" , "Sawn reed (anag.)" .)
