Dashed into the ship for supplies (6)
I believe the answer is:
stores
'supplies' is the definition.
(I've seen this in another clue)
'dashed into the ship' is the wordplay.
'dashed' becomes 'tore' (I've seen this in another clue).
'into' is an insertion indicator.
'the ship' becomes 'SS' (prefix in ship names eg SS Great Britain).
'tore' put into 'ss' is 'STORES'.
'for' is the link.
(Other definitions for stores that I've seen before include "Retail outlets" , "Accumulates, saves up" , "Lays in, hives away" , "Lays away for future use" , "reserve" .)
