Inside the city, he found that the Zirk cavalry from Krink had thrust up one of the broader streets to within a thousand yards of the Palace, and, supported by infantry, contragravity, and a couple of air-tanks, were pounding and hacking at a mass of Skilkans whose uniform lack of costume prevented distinguishing between soldiery and townsfolk. Very few of these, he observed, seemed to be using firearms; with his glasses, he could see them shooting with long Northern air-rifles and a few Takkad Sea crossbows. Either weapon would shoot clear through a Terran or half-way through an Ullran at fifty yards, but at over two hundred they were almost harmless. There were a few fires still burning from the bombardment of the night before--Ullran, and particularly North Ullran, cities did not burn well--and the blaze which had consumed the bulk of Firkked's stock of thermoconcentrate fuel had long ago burned out, leaving an area of six or eight blocks blackened and lifeless. The ship let down, while the six combat-cars which had accompanied her buzzed the Palace roof, strafing it to keep it clear, and the Kragans aboard fired with their rifles. She came to rest on seven-eights weight reduction, and even before the gangplanks were run out, the Kragans were dropping to the flat roof, running to stairhead penthouses and tossing grenades into them. The taking of the Palace was a gruesome business. Knowing exactly how much mercy they would have shown had they been storming the Residency, Firkked's soldiers and courtiers fought desperately and had to be exterminated, floor by floor, room by room, hallway by hallway. They had to fight for every inch downward. Driving down from above, von Schlichten and his Kragans slithered over floors increasingly greasy with yellow Ullran blood. He had picked up a broadsword at the foot of the first stairway down; a little later, he tossed it aside in favor of another, better balanced and with a better guard. There was a furious battle at the doorways of the Throne Room; finally, climbing over the bodies of their own dead and the enemy's, they were inside. * * * * * Here there was no question of quarter whatever, at least as long as Firkked lived; North Ullran nobles did not surrender under the eyes of their king, and North Ullran kings did not surrender their thrones alive. There was also a tradition, of which von Schlichten was mindful, that a king must only be killed by his conqueror, in personal combat, with steel.
