Less than a minute later, the dromon was pulling away from the ship and heading straight toward the enemy fleet. John was standing in the stern, giving orders to the steersman.
Belisarius did not watch for more than a few seconds. He had his own problem to face.
How best to use his little artillery ship against over two dozen opponents?
A thought came from Aide:
Cross the T.
Explain, commanded the general.
A series of images came to his mind. Scenes of naval battle, featuring ships pounding at each other with cannons. In each instance, the fleets attempted to sail their own ships directly across the coming line of the enemy, in order to bring their broadsides to bear on as many opponents as possible.
Belisarius scratched his chin, pondering. The scenes which Aide had shown him were not entirely relevant to his situation. His ship was armed with only two scorpions, located amidships, not a line of cannons running down the entire sides of the ship. “Broadsides,” thus, were impossible.
Still—
The sailor whom John had named as his substitute was now standing next to Belisarius, waiting for orders. The general turned to Honorius, and began gesturing to illustrate his question.
“Can you row this ship at a right angle across the front of that approaching fleet?”
Honorius squinted at the enemy ships. Aegidius’ armada was now well into the Bosporus, about a mile distant.
“Easily. They’re letting the basket ships set the pace instead of the akatoi. Those corbita are slow to begin with. And if they’re packed with cataphracts—and all their armor—they’ll be a lot more sluggish than usual.”
He leaned over the wall of the fighting platform and began shouting orders to his crew. The ship began taking a new heading, but Belisarius did not bother to watch. His concentration was focussed on the scorpions.
John, he saw, had chosen his weapons well. The scorpions were that type of stone-throwing catapult which were called palintonos. The name was derived from the “fold-back spring” design which allowed the two torsion arms to swing forward further than was possible in the more traditional “straight-spring” euthytonos. The weapons were mounted on the same type of tripod base which Roman engineers used for cranes and hoists. The scorpions were then fitted onto a swivel attachment atop the tripod. The end result was a weapon which could be tilted up or down as well as swung sideways in a complete circle.
Romans did not manufacture their artillery engines to the same degree of standardization as would be common in future eras. But, from long experience, Belisarius recognized that the two scorpions were both in what was considered the “11-pound” class—that being the weight of stone shot each was capable of hurling. Using that weight of shot, they had an effective range of well over 400 yards.
“How heavy are your firebombs?” he asked Eusebius.
“A little over eight pounds. Not more than nine.”
Belisarius nodded.
“We should have a range of almost five hundred yards, then.”
Again, he examined the scorpions. The weapons were placed on either side of the wood-castle, far enough apart to allow the engines to be swiveled without the six-foot-long firing troughs impeding each other. Unfortunately, of course, there was no way that both of them could be used simultaneously to fire over the same side. As they—to use Aide’s expression—“crossed the T,” one of the scorpions would be out of action completely.
For an idle moment, Belisarius pondered alternate ways of emplacing artillery on a ship. Almost immediately, another image came from Aide.
A steel ship, very sleek for all its gargantuan size, plowing through the sea. Cannons—three of them abreast—were mounted in a strange sort of enclosed swivel—
Turret.
—directly amidship. Two enclosed swivels—
Turrets.
—were mounted toward the bow, one toward the stern. Those cannons could be brought to bear in any direction. All nine could be employed in broadsides, to starboard or port. Six could also fire across the bow, and three across the stern.
“Oh, well,” muttered Belisarius. “We’ll have to make do with what we’ve got.”
The enemy fleet was now almost within catapult range. The nearest ships were off their starboard bow at a thirty-degree angle. Examining the situation, and doing his best to estimate relative speeds, Belisarius decided that they would be able to use both scorpions for at least three minutes before the port scorpion could no longer be brought to bear.
