The rest of the crew, who would number at least 150, were assigned to the fighting deck. A hundred of those would man the upper bank of oars, two men to an oar, while the rest served as archers and boarders. In the event of a drawn-out pursuit or engagement, the upper rowers would switch places with the soldiers, thus keeping the men from becoming exhausted.
Technically, Eusebius knew, their ship was also classed as a dromon, an oared war galley. But it was the medium-sized type called a pamphylos. They only had eighty oars, twenty on each bank. And there was only room for a single rower on the upper oars.
A hundred and fifty rowers versus eighty. Despite the greater weight of the approaching dromon, it would still be faster than their own galley. And they were further handicapped because of the modifications which John had made in their warship.
John had known he would be heavily outnumbered in the coming battle—one ship against twenty, probably more. So he had decided to use his single ship as a pure artillery vessel, bombarding the enemy fleet at long range with his firebombs. For that reason, they only carried twelve fighting men—just enough to operate the two scorpions. They would be hopelessly outmatched in the event of a boarding.
True, they also carried a double crew of rowers. If John's battle plan worked, his men would be rowing for long periods. So he had loaded the ships with relief rowers. That would give them a greater endurance than the crew of the approaching dromon, but the weight of the extra rowers would also slow them down.
Not to mention—
Eusebius studied the fighting platform he was standing on. The wood castle was larger and heavier than normal
