He had never elaborated on this creed for Collegium, for there it would not have been understood. He had never lain with Tynisa who had, he knew, wanted it. Particularly he had never lain with Cheerwell, who would have agreed, for all the wrong reasons, if he had asked.

Basila buckled on her sword and, seeing Salma smiling at her, ventured a small one of her own.

‘Off to a hard day’s beating people?’ he asked, and her smile slipped. He assumed it was annoyance at him, but then she said, ‘It is dawn. The enemy is advancing on the walls.’

He dressed as fast as he could, his belongings having been returned to him. He took up the stolen Wasp sword without even buckling on a scabbard. Basila was now gone to join her unit or await prisoners or whatever she had to do. She had left him to cower here behind doors like the slaves of Tark and await his fate, and that cut deep.

He found Totho emerging from the next-door room just as he left. For a second he had time to wonder whether the halfbreed artificer had heard anything of the previous night’s activities, before recalling that Basila, of course, had been silent throughout.

So Totho heard nothing but the whole city knows we did it. He had to grin privately at that.

‘What’s going on?’ Totho asked sleepily.

‘The Wasps are attacking. Get your sword and bow.’

‘But the Ants won’t let us fight-’

‘Totho, if enough of the Wasps get over the wall, then our hosts’ preferences won’t come into it.’

Salma bolted up the stairs as Totho turned back for his gear.

They had been billeted in the rooms beneath Parops’s tower. Salma chose the first outside door, the ground-level door, and stopped with it half open, frozen.

The space before the gate was filled with ranks of Ant-kinden soldiers with crossbows and plenty of quarrels. Above them the walls, their crenellations slightly scarred from the previous day, were lined with more of them, and some of those had greater weapons. There were nailbow-men there with their blocky, firepowder-charged devices, and two-man teams with great winch-operated repeating crossbows resting on the walls.

They were shooting. All the men on the walls were shooting, either straight ahead or slightly upwards. Salma heard the grinding thunder of mechanisms, and the arm of the trebuchet atop Parops’s tower flung itself forward, slinging its load of man-sized stones in a high arc. All along the slice of wall that Salma could see, other engines were busy doing the same.

Then the Wasps were at the wall itself, and what he had only been told about became real.

The first wave was a great ragged sweep of spear-wielding savages who hurtled into a field of crossbow bolts. There were already deep holes punched in their scattered mass. Salma watched almost three in four get ripped from the sky in that first instant, as soon as their silhouettes appeared in the sky above the walls. Some were killed outright. Others screamed and plummeted from the air to be finished on the ground with pragmatic brutality. The surviving attackers paid them no heed. Some alighted on the walls. Others ploughed into the waiting men below or scattered across the city. They were in a blood-rage, foaming at the mouth, hurling their spears and blasting with their stings, drawing great slashing swords from their belts to lay about them. One came down close to the tower’s entrance, flinging his lance with such force that it punched right through an Ant’s chainmail, knocking the man off his feet. Salma leapt out instantly, taking to the air and dropping on the attacker with sword extended. Another Ant was there already, and the Wasp savage took both sword-blows simultaneously. He howled in something that was more rage than pain, swinging his own blade at Salma and then at the Ant soldier, cutting a long dent in the latter’s shield before falling.

There was a second wave of them at the walls already, coming too swiftly for many of the soldiers to have reloaded, although the repeating bows had taken a savage toll of the incursors. There was now hand-to-hand fighting all along the wall, and attackers kept dropping, or sometimes falling, down into the courtyard before the gates.

Salma had never seen Ants in combat before. There was no confusion here, no hesitation. The invaders were set upon efficiently, without haste. All found that any Ant they attacked was ready for them as those they tried to surprise turned to see them. The Ants had a hundred pairs of eyes watching each one’s back. The Wasps took a toll with their stings and their frenzied hacking, but how small that toll was! Most of their second wave had been turned into corpses, all for the loss of no more than two dozen defenders.

‘Get back inside, you!’ one of the Ants shouted over at him. ‘No place here for a civilian.’

‘I’m not a civilian!’ Salma called back. ‘Look, I have a sword!’

The man was about to answer him when something pulled his attention upwards. They were all looking up, and across all those raised faces one expression was asking: ‘What…?’

And then they were moving. Without a word, without panic or cries of alarm, they scattered as best they could. Those at the edge of the square were backing quickly into the side streets, others were pushing up against the wall itself. Some found the shelter of doors or doorways. All this in the space of seconds. Salma would have remained standing still if an Ant had not cannoned into him, pushing him back into the tower door, where he collided with Totho so that all three of them fell in a heap.

The first explosion came across the other side, just left of the main gate. A crack of sound, a burst of fire and stone and dust, flinging half a dozen soldiers up and away, shearing through the next nearest squad with jagged metal and shards of stone. Up above, the trebuchet was winching itself ponderously round, while other enemy missiles were landing now, some right before the gates and others impacting on nearby buildings in a sporadic and random rain of fire. Wherever they struck, they split and burst, cracking stone and flinging pieces of their shells in scything arcs. Soldiers everywhere were holding their shields up, falling back to what cover they could find. Each second yet another fireball burst close about the gates, and there had been so many soldiers gathered there a moment ago that each missile claimed at least one victim. Salma, clinging to the doorframe, saw shields punched inwards by the invisible fists of these explosions, a nearby door smashed to kindling, men and women given a second’s notice before being blown apart.

Yet there were no screams, and it seemed horribly unreal with that essential element missing. The Wasps that had come in first had screamed and shouted in fury and terror, but the Ants even died in silence, save for whatever last words they conveyed through that essential communion between them. In their last moments, he wondered, was that link a blessing for the fallen, or a torture for those still standing?

The artillery atop the wall was still pounding away, and Salma could see the Ant-kinden weapons, the ballistae, catapults and all the other murderous toys of the Apt, pivoting and tilting to get the range of the enemy siege engines. Totho went struggling past him, repeating crossbow cradled in his hands, even as another wave of Wasps passed overhead. These were the ones that Salma was familiar with, more disciplined and better armoured: the imperial light airborne. There were crossbows enough to deal with them but they had seized their moment and swiftly struck before the defenders had regrouped. Some circled overhead, spitting down with their stings, while others bedevilled the wall or passed into the city. There were strangers amongst them, Salma spotted: men of another kinden wearing breastplates and leathers in the imperial colours. One of these passed low over the crouching soldiers, and cast something behind him that erupted in a plume of fire and shattered paving flags.
