Then, what with its own weight, what with the weight of the laden bridge,—which dragged upon it from behind,—the huge sow began to tilt backwards, and slide down the slimy bank.

The men on the top tried vainly to keep their footing, to hurl grapnels into the rampart, to shoot off their quarrels and arrows.

“You must be quick, Frenchmen,” shouted Hereward in derision, “if you mean to come on board here.”

The Normans knew that well; and as Hereward spoke two panels in the front of the sow creaked on their hinges, and dropped landward, forming two draw-bridges, over which reeled to the attack a close body of knights, mingled with soldiers bearing scaling ladders.

They recoiled. Between the ends of the draw-bridges and the foot of the rampart was some two fathoms’ depth of black ooze. The catastrophe which Hereward had foreseen was come, and a shout of derision arose from the unseen defenders above.

“Come on,—leap it like men! Send back for your horses, knights, and ride them at it like bold huntsmen!”

The front rank could not but rush on: for the pressure behind forced them forward, whether they would or not. In a moment they were wallowing waist deep, trampled on, and disappearing under their struggling comrades, who disappeared in their turn.

“Look, Torfrida! If they plant their scaling ladders, it will be on a foundation of their comrades’ corpses.”

Torfrida gave one glance through the openings of the hoarding, upon the writhing mass below, and turned away in horror. The men were not so merciful. Down between the hoarding-beams rained stones, javelins, arrows, increasing the agony and death. The scaling ladders would not stand in the mire. If they had stood a moment, the struggles of the dying would have thrown them down; and still fresh victims pressed on from behind, shouting “Dex Aie! On to the gold of Ely!” And still the sow, under the weight, slipped further and further back into the stream, and the foul gulf widened between besiegers and besieged.

At last one scaling ladder was planted upon the bodies of the dead, and hooked firmly on the gunwale of the hoarding. Ere it could be hurled off again by the English, it was so crowded with men that even Hereward’s strength was insufficient to lift it off. He stood at the top, ready to hew down the first comer; and he hewed him down.
