"I am plighted, Nigel!" she replied with an equal seriousness. "Let us go on!"

They rose up from the table and went out, mounted and rode on to Plattling. And this time Nigel bade Blick and the troopers ride in front so that they might bring back word if any hindrance barred the road. For Nigel had noticed, and so had Blick, that the roads were patrolled by parties of the Elector's own bodyguard of horse, a circumstance which would have had no significance if they had been upon the road between Ratisbon and Ingolstadt, from which the Swedish troops might at any time arrive. Still, beyond a salute the Bavarian troopers gave no sign. The two rode on.

But as they neared Plattling and the bridge across the Isar by which they would reach the road to Passau, Sergeant Blick came back in haste and warned them that the passing of the bridge was forbidden by a strong party of cavalry in charge of an officer.

Nigel spurred his horse forward, and the Archduchess did the like. They were soon at the bridge.

The officer was unknown to Nigel, but they saluted with great ceremony. The officer saluted with still greater ceremony the Archduchess.

"My escort, captain, tells me you are unable to let us pass the bridge!" said Nigel.

"My instructions are that in sum!" said the officer.

"It would give us pleasure to hear them," said the Archduchess.

"As regards your Imperial Highness," said the officer, "my instructions were that, should you at any time desire to cross, I was to take care that you had an escort of at least fifty men and two officers. I can furnish them at once."
