He began swimming toward it. He maintained the same powerful breaststroke. It was a relatively slow method—Belisarius was an excellent swimmer, and was quite capable of moving more rapidly in water—but it would be fast enough. And the breaststroke had several advantages. It was almost silent; it kept his arms and legs from flashing above the surface of the water; and—with the knife in his teeth—it enabled him to breathe easily.
Fortunately, the angle was good, and so he was able to position himself where he needed to be a full half-minute before the galley swept through the area. Treading water, directly in the galley’s path, he waited. As he had hoped, the Malwa soldiers aboard the galley were not holding lanterns over the bow. The lanterns were being held toward the stern. The soldiers on that galley, like all the Malwa, did not really think that Belisarius had gone anywhere but the near shore. It was that south bank of the river that the soldiers were watching, even as they headed in the opposite direction.
The galley was almost upon him. Belisarius took a deep breath and dove below the surface. For a moment, he feared that the bundle he was towing might act as a buoy, hauling him back toward the surface. But his clothing was now completely waterlogged. If anything, the bundle simply acted as a weight.
Now, swimming below the barge, down its starboard side, Belisarius encountered the first snag in his hastily-improvised plan.
He was blind as a bat. He couldn’t see a thing.
He had expected visibility to be limited, of course, at night-time. But he had thought he would be able to see enough to guide himself. What he hadn’t considered, unfortunately, was the nature of the Jamuna itself.
This was no mountain stream, with clear and limpid waters. This was a great, murky, slow-moving valley river. Heavy with silt and mud. It was like swimming through a liquid coal mine.
He guided himself by sound and touch. To his left, he used the splashing oars as a boundary. To his right, stretching out his fingers, he groped for the planks of the hull.
He misgauged. Driven, probably, by an unconscious fear of his sudden blindness, he swam too shallow. His head, not his fingers, found the hull.
The impact almost stunned him. For a moment, he floundered, before he brought himself under control. Quickly, he found the hull with his fingers.
The wood planks were racing by. He heard a sudden dimunition in the sound of the oars, as if they had passed him.
Now.
He took the knife from his teeth and thrust it upward, praying the little blade wouldn’t break. The tip sank into the wood. Not far—half an inch—but enough.
Using the knife to hold himself against the hull, Belisarius desperately sought the surface. He was almost out of air.
Again, he had misgauged. He was still too far from the stern. The side of his face was pressed against the hull. He could feel the surface of the water ruffling through his hair, but could not reach it to breathe.
He jerked the knife out, let the current carry him for a split second, stabbed again. The thrust, this time, was even feebler.
It was enough, barely. The blade held. He let the current raise him up against the hull. His head broke water.
His lungs felt like they were about to burst, but he took the time for a quick upward glance before taking a breath.
Finally, something went as planned. As he had hoped, he was hidden beneath the overhang of the stern. He opened his mouth and took a slow, shuddering breath, careful to make as little sound as possible.
For a minute, he simply hung there, breathing, resting. Then he took stock of his situation.
The situation was precarious. The knife was barely holding him to the hull. It could slip out at any moment. If it did, the galley would sweep forward, leaving him cast behind in its wake. He was not worried so much at being spotted, then, but he could not afford to lose the shelter of the galley. The shelter—and the relaxation. He had no desire to make the long swim to the opposite shore on his own effort. He could make it, yes, but the effort would leave him exhausted. He could not afford exhaustion. He still had many, many hours of exertion before him. A day, at least, before he could even think to rest.
