Historical ship all gone sadly (7)
I believe the answer is:
galleon
'historical ship' is the definition.
'galleon' can be an answer for 'ship' (type of ship). I'm unsure of the 'historical' bit.
'all gone sadly' is the wordplay.
'sadly' is an anagram indicator.
'all'+'gone'='allgone'
'allgone' is an anagram of 'GALLEON'.
Can you help me to learn more?
(Other definitions for galleon that I've seen before include "One might sink" , "Trader" , "Spanish treasure ship" , "Ship of the line" , "Historical warship with three or more masts" .)
