Sink the Spanish ships in AC4 Black Flag

"Sink the Spanish ships" is the last mission objective in Sequence 3 / Memory 06: Proper Defenses

Walkthrough[edit]

You need to sink 8 enemy ships

Use all your firepower against the eight gunboats

Try to keep moving, circling the enemy ships and constantly firing. Since the enemy ships are grouped together, you are likely to hit at least one enemy ship each time your cannons fire. And since you are on the move, the enemy ships will have a hard time hitting you.
