Belisarius glanced at his companions. All of them were frowning—the veterans with simple puzzlement, but Menander with concentration.
"It didn't fly straight," announced the young cataphract. "It shot off at an angle. It should have hit the wall fifteen or twenty feet to the east."
"Exactly," said Belisarius with satisfaction. "If you watch carefully, and keep track, you'll eventually notice that the cannonfire is very erratic. Occasionally they shoot straight. But more often the ball will sail off at an angle—and the elevation's just as haphazard."
"Why?" asked Menander.
"It's the clearance," replied the general. "What's called windage. In order for a cannon to shoot straight, the ball has to fit snugly in the bore. That requires two things—an even, precise bore all the way through the cannon barrel, and cannonballs that are sized to match."
Anastasius puffed out his cheeks. "That's a tall order, general. Even for Greek artisans."
Belisarius nodded. "Yes, it is. But the better the fit, the better the fire. The Malwa don't even make the attempt. Those cannonballs aren't much more than crude stones—they'd do better to use iron—and the cannon barrels are simply castings. They're not machined at all. Even the casting process, I suspect, is pretty crude."
Valentinian scowled. "How would you machine something that big in the first place?" he demanded. "Especially metal."
Belisarius smiled. "I wouldn't even try, Valentinian. For cannons the size of these, sloppy accuracy isn't really that much of a problem. But let's examine the question from a different angle. How hard would it be to machine a very small cannon?"
"Very hard," said Anastasius instantly. His father was a blacksmith, and had put his boy to work at an early age. "Any kind of machining is difficult, even with wood. Almost nobody tries to do it with metal. But—yes, if it was small enough—"
"Hand cannons," said Menander excitedly. "That's what you'd have. Something small enough for a single man to fire—or maybe two."
"One man," pronounced Belisarius.
"I haven't seen any such weapons among the Malwa," said Valentinian uncertainly. "Maybe—" He fell silent, coughing. There was a soft wind blowing, and the cloud of gunsmoke emitted by the recent cannonblast had finally wafted over the Romans.
"God, that shit stinks," he muttered.
"Better get used to it," said Anastasius, rather unkindly. For a moment, the giant Thracian seemed on the verge of uttering one of his frequent philosophical homilies, but Valentinian's ferocious glare made him think better of it.
"You haven't seen any handcannons, Valentinian, because the Malwa don't have any." Belisarius' voice was soft, but filled with confidence. "They're not hiding them from us. I'm sure of that. They've kept us far from the battlefield, but not that far. If they had any handcannons, we'd have spotted them by now."
He waited for the roar of another cannonblast to subside before continuing.
"And that's the wave of the future. Handcannons. If we can get back to Rome—if some of us can make it back to Rome, and get this information to John of Rhodes, then we've got a chance. We'll have better powder than the Malwa, and our artisans are more skilled than theirs, on balance. We can build an entirely new kind of army. An army that can defeat this colossus."
For a moment, he considered adding some of the ideas he had been coming to, of late, concerning the structure and tactics of such a future army. But he decided against it. His ideas were still only half-formed and tentative. They would confuse the cataphracts more than anything else. Belisarius needed more time. More time to think. And, most of all, more time to learn from the strange mentality that rested, somehow, in the bizarre "jewel" that he carried in the pouch suspended from his neck. The mentality which called itself Aide and said that it came from the far distant future.
His musings were interrupted by Valentinian.
"Careful," muttered the cataphract. "The Rajputs are coming."
Belisarius glanced over, and saw that a small group of Rajputs had detached themselves from the main body of the elite horsemen and were trotting toward them. At their head rode the leader of the escort, one of the many petty kinglets who constituted the upper crust of the Malwa's Rajput vassals. This one belonged to the Chauhar clan, one of the most prominent of the Rajput dynasties. His name was Rana Sanga.
Watching Sanga approach, Belisarius was torn between two sentiments.
On the one hand, he was irritated by the interruption. The Rajputs—following orders, Belisarius had no doubt—never allowed the Romans to get very close to the action, and never for very long. Despite the limitation, Belisarius had been able to glean much from observing the siege of the rebel city of Ranapur. But he would have been able to learn much more had he been allowed closer, and if his observations were not always limited to a span of a few minutes.
