Old range destroyed in quiet stampede (8,4)

I believe the answer is:

headlong rush

'stampede' is the definition.

'old range destroyed in quiet' is the wordplay.
'destroyed' indicates an anagram.
'in' indicates putting letters inside.
'quiet' becomes 'hush' (hush is a kind of quiet).
'old'+'range'='oldrange'
'oldrange' with letters rearranged gives 'eadlongr'.
'eadlongr' placed within 'hush' is 'HEADLONG RUSH'.

I've seen this clue in The Everyman puzzle in The Observer.
