Watching until the sentry was near the end of the bridge, Gavin, with a few swift strokes, found himself in darkness under the arches. There he waited until the sentry again left the middle of the bridge, and some minutes more of hard pulling carried the boat a considerable distance down the stream. Gavin, pulling away with the greatest energy, congratulated himself on the ease with which he had got out of Breslau.

“As soon as I am quite clear of the outposts,” he thought, “I will go ashore, and make straight for the nearest military post where they do not have to report at Vienna, and with my papers and my uniform I can easily get a safe-conduct through the Prussian lines. And how cheap will St. Arnaud feel when I arrive at Vienna a week ahead of him!”

Inspired with these agreeable ideas, Gavin tugged valiantly at his oars, and being heated with the exercise, took off his coat; his cloak already lay in the bottom of the boat.

Having pulled for nearly two hours, he found himself far in the open country. The moon was then rising, and by its light he saw a smooth, wide road, leading down to a landing-place. Concluding this to be a good place to disembark, he rowed ashore, put on his coat and cloak, and took the road.

He had not travelled more than two miles when he struck the highway to Breslau. He remembered various landmarks at that point, and discovered to his joy that he was quite eight miles from the city gates.

Trudging along cheerfully in the moonlight, away from Breslau, he heard behind him a clatter of hoofs. Ten or twelve troopers, with a non-commissioned officer riding at their head, were coming rapidly down the road. Involuntarily, Gavin started to conceal himself in the hedge by the roadside; but the troopers were too quick for him. One of them saw him, galloped toward him, and, seizing him by the collar, held him until the sergeant rode up.

Gavin made no effort to escape, and, in truth, was rather glad to be caught, and said promptly to the sergeant, a coarse, brutal-looking fellow:

“I am Lieutenant Hamilton, of the First Austrian Hussar Regiment. I have been to Breslau with a flag of truce with a companion, Captain St. Arnaud, of General Loudon’s corps; but being impatient to return to Vienna, I quietly walked away this evening, and if you can help me on my way, I shall be infinitely obliged.”

“I see you wear the uniform of an Austrian officer, but what have you got to prove the remarkable tale you are telling us?” replied the sergeant gruffly.

Gavin put his hand in his breast pocket. It was quite empty.
