Vessels in battle at Preston (4)
I believe the answer is:
pans
'vessels' is the definition.
(I've seen this in other clues)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for pans that I've seen before include "vessels" , "Kitchen utensils" , "roasts" , "kitchen equipment" , "Criticises" .)
