It was his duty to save the money.

He ordered the soldiers to turn back and make the best of their way to Szaszvar, the money that had been already spilt was given up for lost.

It was of no use for mere men to attempt to grapple with such a devil incarnate as Fatia Negra.
"After them, after them!--Give me a horse!" roared Fatia Negra to his comrades as they came galloping up, whereupon they all leaped from their nags, not so much indeed for the sake of giving him a mount as for the sake of grabbing the scattered heaps of ducats.
"Let that alone; it won't run away" cried the adventurer.

"The bulk of it is galloping in front of us--follow me!" And at that, without waiting their decision, he seized one of the horses, swung himself into the saddle and dashed after the lancers.
Nobody followed him.

The robbers were wise enough to perceive that if they left lying here these thousands of ducats, actually won, in order to run after ten times as many which they had still to catch, (not to mention the broken heads which they were sure to get into the bargain), the loafing members of the confraternity who were following behind them on foot, would pocket the booty nicely at their ease, so they stayed where they were, with the comfortable persuasion that Fatia Negra would be sure to turn back when he perceived he was alone.
He, however, never gave them a thought, but putting spurs to his horse, pursued the soldiers.
