Naval battles are best fought with cannons.
Especially when there is a gap in the quality of equipment, the side with the advantage can crush the enemy from a distance with cannon fire, thus minimizing combat losses.
And as it happens, cannon operation is a compulsory subject for students of the "Royal War Academy."
The professional soldiers Barrett brought along with the Judgment Corps were all students of the Royal Academy, and nearly all of them were certified "senior gunners" or "expert gunners."
As a result, when the three warships of the Dawn Corps launched a volley of a hundred cannons, the cannonballs seemed guided by precision, covering the enemy vessels including the "Old Albatross" a few miles away with minimal deviation.
With such firepower, it wouldn't take many rounds to sink the enemy.
Even without using any spells
Su Lun also guessed that there must be experts among the enemies, since they were escorting valuable treasures.
