Edward's Cog Thomas struck its target hard enough to spring a leak before the English secured a grapple on the second attempt. Longbow volleys kept Castilian fighters from using the full height advantage of their raised platforms while English men-at-arms climbed scaling ladders. Once the opposing deck was taken, Edward transferred his flag because his own cog was sinking. The Black Prince's ship was likewise foundering, making capture of an enemy hull a matter of survival rather than merely a prize. Henry of Lancaster attacked the same Castilian vessel from the other side and turned the fight through local numerical superiority. He is described as one of Edward III's most reliable commanders and a loyal supporter of Prince Edward. Boarding combat combined collisions, missile suppression, climbing, and rapid transfer into captured ships.

Longbows and ladders overcome higher ships
English crews used longbow fire and scaling ladders to board taller Castilian ships, often abandoning their damaged cogs for captured vessels.
