He turned to the Avar in scalemail and shouted again. The warrior made as if to argue with him, whereupon the fellow’s shouts turned into screams. George didn’t know what he was saying, but wouldn’t have wanted it said to him.

Reluctantly, the Avar captain accepted the rebuke and the instructions that had led to it. He shouted something himself. The Slavic archers in range of his voice trotted away from the walls of Thessalonica and back toward their encampments. All around the city, the same shouted orders went out to the Avars’ subject allies. George could not see all around the city. As far as he could see, though, the Slavs were giving up the fight for now.

“That’s done it!” Sabbatius cried gleefully. “We’ve shown them they’ve got no business messing with good Roman men!”

His words were almost lost in the cheers that rose from the wall as the defenders of Thessalonica watched the Slavs withdraw. Despite those cheers, Rufus shook his head. “They don’t think the attack will work now--that’s plain enough,” he said. “But they haven’t done all this work so they could go off and leave it. They’ll be back.”

“But--” Paul, for once, sounded as confused as Sabbatius. “That crazy fellow out there, whatever he was, he saw that the power we prayed into the grappling hook was stronger than anything he could do against it.”

“No.” Like Rufus, George had caught the distinction his other comrades were missing. “He saw that what he tried now didn’t work. That doesn’t mean he can’t try something else. Doesn’t mean he won’t try something else, either. I wish it did.”

Sabbatius scowled like a child learning he would have to go to school not only on the first day he’d just survived but also for months to come. “Why, the dirty, cheating son of a poxed ewe!” he exclaimed.

George looked at Rufus. Rufus looked down at the ground. Looking down at the ground didn’t help. The veteran and the shoemaker both started to laugh, and then started bleating out at the Slavs and Avars. Sabbatius and Paul joined them. The bleating spread along the wall. More than a few feet away from the people who’d started it, the militiamen had no idea why they were making noises like sheep, but any derision aimed at their foes seemed worth sending.

The Slavs stared up at the Romans on the wall. Some of them made peculiar gestures. George stopped bleating and started laughing again. “They think we’re cursing them!” he exclaimed.

“Good,” Rufus said, and bleated louder than ever. So did George, wishing the bleats really would do something to the Slavs and Avars.

Even more suddenly than it had begun, the bleating died down. George looked around to find out why, and saw Bishop Eusebius coming down the walkway in his shining vestments. He waited for the bishop, a somber sort, to make some cutting remark about the racket the militiamen had been creating. But Eusebius surprised him. In a great voice, he cried, “Sing out, you lambs of God!”

George didn’t sing out, not at first. He cheered instead, along with most of his companions. But then he did bleat, and hoped that, with Eusebius’ blessing, the sound would gain potency in the spiritual realm. The words of the psalmist ran through his mind: Make a joyful noise unto the Lord, all ye lands. Bleating probably wasn’t the sort of joyful noise the psalmist had had in mind, but George didn’t fret about that.

Eusebius came up to Rufus and said, “I see it is the same here as it is all along the circuit of the wall: they have not dared attack us, feeling the power of the Lord our God.” He pointed to the chain from which the grappling hook hung down over the Litaean gate.

Rufus cleared his throat. “Don’t like to contradict you, Your Excellency, but it looks to me more like they haven’t attacked yet. This Avar… I don’t know… priest, I guess, he tried to overthrow the power in the hook. He didn’t do it, but I wouldn’t swear he can’t do it. You know what I’m saying?”

“I do,” Eusebius answered. “I wish I did not, but I do. We shall be tested in all ways. I pray only that we shall not prove like Belshazzar the king of Babylon, who was weighed in the balances, and found wanting. May our city not be given to the Slavs and Avars, as his kingdom was given to the Medes and Persians.”

“The Persians,” George muttered. Off in the distant east, the Persians still contended with the Roman Empire. When God gave a gift, He gave a long-lasting one--though who heard anything of the Medes these days?

As the Avar wizard’s preposterous costume had drawn Roman eyes to it, so Eusebius’ bright silks stood out among the drab wool and linen tunics the defenders of Thessalonica wore. The Slavs, who had been standing around dejectedly after their overlord’s spells failed to beat down the power in the grappling hooks, now took fresh spirit and began shooting arrows at the bishop.

None of them touched him; his holiness shielded him from them, as the Avar’s power had kept Roman shafts from piercing him. However holy Eusebius was, though, George and his comrades could not match him. They ducked down behind the outer wall of the walkway. “Be careful with those arrows,” Rufus said to Sabbatius when one rebounded back near them. “Remember, the Slavs sometimes poison the points.”

“I wasn’t going to touch it,” Sabbatius said, and gave himself the lie by jerking his hand away. Again he reminded George of a schoolboy, though schoolboys commonly drank their wine well enough watered to keep from getting drunk.

Bishop Eusebius said, “By my presence, I am bringing you brave men into danger. I shall withdraw.” He went over to the stairway and back down into Thessalonica. The storm of arrows died away.

Indeed, but for the short advance of the battering rams, it was as if the efforts of the Slavs and Avars had never been. Paul laughed nervously. “Does it usually get so quiet so fast?” he asked.

“A lot of things about this siege strike me as peculiar,” Rufus answered. “When I was fighting the Goths, now, and then the Lombards, it was Christian against Christian. Oh, they were heretics, but that’s a small thing. Their saints had the same powers as ours, near enough. With the Slavs and Avars, it’s like they aren’t sure what their powers can do to us, or about what God and the saints can do against them. They’re feeling us out as they go.”

“I don’t want any Avar feeling me,” Sabbatius said emphatically. Everyone else tried explaining that it was a figure of speech. Regretfully, George saw again that he didn’t need to be drunk to be stupid.

As the sun crossed the sky, Romans went down from the wall and resumed their normal occupations. George’s shift on duty was long past, but he didn’t feel like descending while Rufus stuck to his post. And the sudden slackening of the assault in which the Avars had apparently put so much effort and so much faith--in several senses of the word--struck him as being as odd and suspicious as it did the veteran. If something was about to happen, he wanted it to happen while he was here to see it and to try to do something about it, not to hear about it after it was done.

Now the light shone in his face, not at his back. He wondered if the Slavs and Avars would renew the attack because of that. He didn’t think so; the sun still blazed high in the southwest, casting only fairly short shadows. It wouldn’t interfere with the Roman archers’ aim.

“Hello!” Rufus said suddenly. “Here comes that cursed wizard or priest again. What sort of deviltries does he have in mind now?” He made the sign of the cross, to rout whatever demons or powers might be lurking to aid the Avar.

If the gesture bothered the fellow, he did not show it. He was not alone this time: a couple of fair-haired, shaggy-bearded Slavs accompanied him. Reading the attitudes of the three of them as best he could across a furlong or so, George guessed the Avar was doubtful and the Slavs to either side of him more confident.
