Agat glanced once at Rolery and was gone into the storm. In a moment the clangor of metal on metal broke out from the tower overhead, booming, snow-muffled. They called that great noise the bell, and before the siege began had all learned its signals. Four, five strokes, then silence, then five again, and again: all men to the Sea Gate, the Sea Gate ...

Rolery dragged the messenger out of the way, under the arcades of the League Hall, before men came bursting from the doors, coatless or struggling into their coats as they ran, armed and unarmed, pelting into the whirling snow, vanishing in it before they were across the Square. No more came. She could hear some noise in the direction of the Sea Gate, seeming very remote through the sound of the wind and the hushing of the snow. The messenger leaned on her, in the shelter of the arcade. He was bleeding from a deep wound in his neck, and would have fallen if she had let him. She recognized his face; he was the Alterran called Pilotson, and she used his name to rouse him and keep him going as she tried to get him inside the building. He staggered with weakness and muttered as if still trying to deliver his message, "They broke in, they're inside the walls ..."

THE HIGH, narrow Sea Gate clashed to, the bolts shot home. The battle in the storm was over. But the men of the city turned and saw, over the red-stained drifts in the street and through the still-falling snow, shadows running.

They took up their dead and wounded hastily and returned to the Square. In this blizzard no watch could be kept against ladders, climbers; you could not see along the walls more than fifteen feet to either hand. A Gaal or a group of them had slipped in, right under the noses of the guards, and opened the Sea Gate to the assault. That assault had been driven out, but the next one could come anywhere, at any time, in greater force.

"I think," Umaksuman said, walking with Agat towards the barricade between the Thiatr and the College, "that most of the Gaal went on south today."

Agat nodded. "They must have. If they don't move on they starve. What we face now is an occupying force left behind to finish us off and live on our stores. How many do you think?"

"Not more than a thousand were there at the gate," the native said doubtfully. "But there may be more. And they'll all be inside the walls—There!" Umaksuman pointed to a quick cowering shape that the snow-curtains revealed for a moment halfway up the street. "You that way," the native muttered and vanished abruptly to the left. Agat circled the block from the right, and met Umaksuman in the street again. "No luck," he said.

"Luck," the Tevaran said briefly, and held up a bone-inlaid Gaal ax which he had not had a minute ago. Over their heads the bell of the Hall tower kept sending out its soft dull clanging through the snow: one, two—one, two— one, two—Retreat to the Square, to the Square ... All who had fought at the Sea Gate, and those who had been patrolling the walls and the Land Gate, or asleep in their houses or trying to watch from the roofs, had come or were coming to the city's heart, the Square between the four great buildings. One by one they were let through the barricades.

Imaksuman and Agat came along at last, knowing it was folly to stay out now in these streets where shadows ran. "Let's go, Alterra!" the native urged him, and Agat came, but reluctantly. It was hard to leave his city to the enemy.

The wind was down now. Sometimes, through the queer complex hush of the storm, people in the Square could hear glass shattering, the splintering of an ax against a door, up one of the streets that led off into the falling snow. Many of the houses had been left unlocked, open to the looters: they would find very little in them beyond shelter from the snow. Every scrap of food had been turned in to the Commons here in the Hall a week ago. The water-mains and the natural-gas mains to all buildings except the four around the Square had been shut off last night. The fountains of Landin stood dry, under their rings of icicles and burdens of snow. All stores and granaries were underground, in the vaults and cellars dug generations ago beneath the Old Hall and the League Hall. Empty, icy, light-less, the deserted houses stood, offering nothing to the invaders.

"They can live off our herds for a moonphase—even without feed for them, they'll slaughter the hann and dry the meat—" Dermat Alterra had met Agat at the very door of the League Hall, full of panic and reproach.

"They'll have to catch the hann first," Agat growled in reply.

"What do you mean?"

"I mean that we opened the byres a few minutes ago, while we were there at the Sea Gate, and let

'em go. Paol Herdsman was with me and he sent out a panic. They ran like a shot, right out into the blizzard."

"You let the hann go—the herds? What do we live on the rest of the winter—if the Gaal leave?"

"Did Paol mindsending to the hann panic you too, Dermat?" Agat fired at him. "D'you think we can't round up our own animals? What about our grain stores, hunting, snowcrop—what the devil's wrong with you!"

"Jakob," murmured Seiko Esmit, coming between him and the older man. He realized he had been yelling at Dermat, and tried to get hold of himself. But it was damned hard to come in from a bloody fight like that defense of the Sea Gate and have to cope with a case of male hysteria. His head ached violently; the scalp wound he had got in one of their raids on the Gaal camp still hurt, though it should have healed already; he had got off unhurt at the Sea Gate, but he was filthy with other men's blood. Against the high, unshuttered windows of the library the snow streaked and whispered. It was noon; it seemed dusk. Beneath the windows lay the Square with its well-guarded barricades. Beyond those lay the abandoned houses, the defenseless waLls, the city of snow and shadows.

That day of their retreat to the Inner City, the fourth day of seige, they stayed inside thenbarricades; but already that night, when the snowfall thinned for a while, a reconnoitering party slipped out via the roofs of the College. The blizzard grew worse again around daybreak, or a second storm perhaps followed right on the first, and under cover of the snow and cold the men and boys of Landin played guerrilla in their own streets. They went out by twos or threes, prowling the streets and roofs and rooms, shadows among the shadows. They used knives, poisoned darts, bolos, arrows. They broke into their own homes and killed the Gaal who sheltered there, or were killed by them.

Having a good head for heights, Agat was one of the best at playing the game from roof to roof.

Snow made the steep-pitched tiles pretty slippery, but the chance to pick off Gaal with darts was irresistible, and the chances of getting killed no higher than in other versions of the sport, streetcorner dodging or house-haunting.

The sixth day of seige, the fourth of storm: this day the snowfall was fine, sparse, wind-driven.

Thermometers down hi the basement Records Room of the old Hall, which they were using now as a hospital, read —4C. outside, and the anemometers showed gusts well over a hundred kmh. Outside it was terrible, the wind lashing that fine snow at one's face like gravel, whirling it in through the smashed glass of windows whose shutters had been torn off to build a campfire, drifting it across splintered floors. There was little warmth and little food anywhere in the city, except inside the four buildings around the Square. The Gaal huddled in empty rooms, burning mats and broken doors and shutters and chests in the middle of the floor, waiting out the storm. They had no provisions—what food there was had gone with the Southing. When the weather changed they would be able to hunt, and finish off the townsfolk, and thereafter live on the city's winter stores.
