Several deliveries arrived crushed (8)
I believe the answer is:
overcame
'crushed' is the definition.
(overcoming is a kind of crushing)
'several deliveries arrived' is the wordplay.
'several deliveries' becomes 'over' (I've seen this before. I am not sure about the 'several' bit.**).
'arrived' becomes 'came' (coming is a kind of arriving).
'over'+'came'='OVERCAME'
Can you help me to learn more?
(Other definitions for overcame that I've seen before include "Defeated or got over" , "Got the better of" , "prevailed" , "Conquered" , "Beat (someone)" .)
