"Hush, man, and come help. We may annihilate the whole crew at a blow," said the old soldier, who had no petty scruples about ways and means; "an enemy dead is a friend the more, however he come by his end."

Scarlett and Wat stole to the wall and peeped cautiously over. The ill-laid and mouldered stones tottered even as they leaned against them; one or two rattled into the defile as they looked down. The heads of the pursuers were just appearing at the entrance of the dell. One of them was training his piece to shoot it off at the girl, who ran lightly as at a frolic a hundred yards in front.

Without a suspicion of danger the assailants came posting along.

"Now, with all your might!" cried Scarlett, when he saw the villains exactly underneath. He could plainly descry the same four men who had sat about the table in the Hostel of the Coronation, and some of the others also who had flocked in thither to join the fray.

So without further word Wat and Scarlett set their thews to the wall; and between them, panting with the long chase and grimed with powder, where the touchhole had spat up in her face, the Little Marie threw herself on the parapet to help on the catastrophe with all her feeble strength.

The wall swayed in a piece and quivered a moment on the verge ere it fell with a prodigious crash upon the straggling file of men in the deep defile below. A hoarse, confused cry was heard, running up, as the pursuers too late recognized their danger, into a shriek of agony. Then a thick cloud of dust and sand arose, which prevented those in the redoubt from seeing the effect of their stratagem. Presently from the gap they could see a few limping stragglers disentangle their disabled bodies from the ruins, and make haste to put as much space as possible between themselves and the unseen dangers which beset them on every side on these wide, unwholesome dunes.

The Little Marie stood erect in the breach. She held her pistols in her hand and marked down the survivors as they ran.

"Let them go, Marie," cried Wat; "they are powerless to harm us now!"

Wat's heart was a little turned to pity by the wholesale destruction wrought beneath his eyes by the falling of the wall; but Marie's eyes only glistened the more brightly with excitement and the light of battle.

"But they are your enemies, my captain!" said Marie, evidently surprised at his words. Then very coolly she went on loading her pistols.
