“Hold it. Drag him clear, Stubbi. All right. Pick-and-shovel party back into cover. Heave now, boys, and make it a good one. There—she’s home! Hammer in the piles, Brand, so she doesn’t roll back. Drop the ladders. Archers to the top platform. Storming party, after me.”

One pair of ladders took the heavily armed and armored men up twelve feet, all of them gasping now with exertion but swept along with excitement. More ladders, another twelve feet. A hand passed Shef his halberd, forgotten in the rush. He seized it, watched the men jamming close together on the top platform. Were they level with the wall?

Yes! He could see the battlements below him, not much more than knee height. There was an Englishman shooting upward. The point found a gap between the planks, whirred through till the shaft caught and snapped, ended an inch from his good eye. Shef broke it off and dropped it. The men were ready now, all waiting for the signal.

Shef laid the razor edge of his halberd to the rope and cut.

Immediately the drawbridge began to fall forward, slowly for a moment, then hurtling forward like a great hammer, its front edge weighted with sandbags. A thump, a cloud of sand blowing in the wind as a bag burst, bowstrings twanging just above him as the archer tried to keep the battlements clear.

Then a great grunt as Brand propelled his massive frame onto the drawbridge and hurled himself across, beard-axe raised. As Shef leapt to follow, arms closed round him from behind. He found himself staring over his shoulder at Ulf, the ship’s cook, the biggest man in three crews, after Brand.

“Brand said not you. He said keep you out of trouble for a few minutes.”

The men poured by, first the detailed storming party, then the rest of the machine’s crew, flinging themselves up the ladders and across the drawbridge without a pause. Then the men from the pick-and-shovel teams followed the rest of Brand’s crew. Shef struggled in Ulf’s grip, feet off the ground, hearing the clash of weapons, the screaming and shouting of the battle.

As complete strangers from other crews began to haul themselves up the ladder, Ulf released his grip. Shef leapt out onto the drawbridge, out into the open air, and for the first time could see how his plan had worked.
