Stopped Edward pursuing Henry (6)
I believe the answer is:
halted
'stopped' is the definition.
('halt' can be a synonym of 'stop')
'edward pursuing henry' is the wordplay.
'edward' becomes 'ted'.
'pursuing' is a charade indicator (letters next to each other).
'henry' becomes 'hal'.
'ted' after 'hal' is 'HALTED'.
(Other definitions for halted that I've seen before include "Caused to stop" , "Stopped or interrupted" , "Came to a sudden stop" , "Checked" , "Came to a stop, ceased to move" .)
