Vasudeva was rich, now, for he had been the only Kushan to dare that gamble. Rich, not so much in material wealth—his soldiers had had little to wager, after all—but in the awe and esteem of his men. Kushans admire a great gambler.
“How did you know?” asked one of his lieutenants.
Vasudeva smiled.
“He promised me. When we gave our oath to him, he swore in return that he would treat Kushans as men. Executed, if necessary. But executed as men. Not hanged like criminals, or beaten like dogs.”
He pointed to the river below Peroz-Shapur. “Or drowned, like rats.”
The lieutenant frowned. “He made that vow to us, not—” A gesture with his head upriver. “—to those Kushans.”
Vasudeva’s smile was quite like that of a Buddha, now.
“Belisarius is not one to make petty distinctions.”
The commander of the Kushan captives turned away.
“Your mistake was that you bet on the general. I bet on the man.”
Two days later, at Babylon, Khusrau Anushirvan also basked in the admiration of his subordinates. Many of them—many—had questioned his wisdom in placing so much trust in a Roman general. Some of them had even been bold enough, and honest enough, to express those reservations to the Emperor’s face.
None questioned his wisdom now. They had but to stand on the walls of Babylon to see how wise their Emperor had been. The Malwa fleet had been savaged when Belisarius lowered the river. It had been savaged again, when he restored it. A full quarter of the enemy’s remaining ships had been destroyed in the first few minutes. Tethered to jury-rigged docks, or simply grounded in the mud, they had been lifted up by the surging Euphrates and carried to their destruction. Some were battered to splinters; others grounded anew; still others, capsized.
And Khusrau had sallied again. Not, this time, with dehgans across a pontoon bridge—no-one could have built a bridge across the roaring Euphrates on that day—but with sailors aboard the handful of swift galleys in his possession. The galleys had been kept ashore until the river’s initial fury passed. As soon as the waters subsided to mere turbulence, the galleys set forth. Down the Euphrates they rowed, adding their own speed to the current, and destroying every Malwa ship they encountered which had managed to survive the Euphrates’ rebirth.
There was almost no resistance. The galleys passed too swiftly for the enemy’s cannons to be brought to bear. And the Malwa soldiers on the ships themselves were too dazed to put up any effective resistance.
Down the Euphrates the galleys went, mile after mile, until the rowers were too weak to pull their oars. They left a trail of burning ships thirty miles behind them, before they finally beached their craft and began the long march back to Babylon. On the west bank of the river, where the Malwa could no longer reach them.
Between the river and the Persian galleys, over half of the remaining Malwa fleet was destroyed. Not more than two dozen ships eventually found their way back to Charax, of the mighty armada which had set forth so proudly at the beginning of the year.
Other than sending forth the galleys, Khusrau made no attempt to sally against the Malwa encamped before Babylon. He was too canny to repeat Kurush’s mistake at Peroz-Shapur. The Malwa lion had been lamed, true. It had not been declawed. There were still a hundred thousand men in that enemy army, with their siege guns loaded with cannister.
The Emperor simply waited. Let them starve.
The siege of Babylon had been broken, like a tree gutted by a lightning bolt. It had simply not fallen yet, much like a great tree will stand for a time after it is dead. Until a wind blows the hollow thing over.
That wind arrived twelve days later. Emperor Khusrau and his entourage, from the roof of Esagila, watched the survivors of the Malwa expedition drag their mangled army back into the camps at Babylon. That army was much smaller than the one which had set out a few weeks since. Smaller in numbers of men, and horses, and camels, positively miniscule in its remaining gunpowder weapons.
