After making a sign of acquiescence in reply to the orders they had received, the Ulmens immediately regained their respective posts, and during some minutes the battle continued to rage with the same fury. But all at once a mass of fifteen hundred Indians simultaneously rushed with inexpressible force against the centre squadron, in which Don Tadeo fought, and enveloped it on all sides.

"Caramba!" shouted Valentine, "we are surrounded! Mon Dieu! we must disengage ourselves, or these demons will cut us up."

And he dashed headlong into the thickest of the combatants, followed by the rest of his party. After a hot struggle of three or four minutes, they were safe and sound outside of the fatal circle.

"Hum!" said Valentine, "rather sharp work. But, thank God, here we are."

"Yes," the count replied, "we have had a narrow escape! But where is Don Tadeo?"

"That is true," Valentine observed. "Oh," he added, striking his brow with anger, "I see it all now. Quick, to the rescue!"

The two young men placed themselves at the head of the horsemen who accompanied them, and rode back furiously into the mêlée. They soon perceived the person they were in search of; Don Tadeo, supported by only four or five men, was fighting desperately.

"Hold out! hold out!" Valentine shouted.

"We are here! Courage, we are here!" the count cried.

Their voices reached Don Tadeo, and he smiled.
