Burton at once dashed after them, anxious about the safety of his friends at the cart, even more than about the peril of the whole party if the enemy's march should be hastened. Young Marco flew along at his heels. But the fugitives had had too long a start. Even the beam of the torch failed to discover them. Immediately after the torch flashed there was the report of a revolver, and Burton ran at break-neck pace down the rugged track. He came to the cart.

"Gone away!" cried Enderby.

"You're not hurt?"

"It was Nuta's revolver. We heard some one coming, but didn't know whether friend or foe until you flashed your torch. Then I guessed. But two men were just on us then; they swerved to avoid the cart, and dashed away beyond us there. The woman was quick, but it was too dark to aim, and I'm afraid they've both got clear."

"That's a pity. They'll report that we've got the tower, and the Bulgars may swarm up in an hour or two. We must get you out of harm's way."

He made signs to Marco that he wished the cart to be driven up at once. The boy whipped up the oxen, and the vehicle lumbered away with Hildenheim trudging disconsolately behind. At the gate in the wall they met old Marco.

"Let the woman and the boy go on with your wounded friend," he said to Burton. "They cannot help us; why should we endanger them? Moreover, they would then save the goods in my cart."

"As you please," said Burton. "But you yourself will hold to your agreement, and help us to check the enemy as long as we can?"

"Assuredly, and Milosh Nikovich will remain with me."

But when the matter was put to Nuta, she resolutely refused to leave the old man.
