“Friend,” he answered thickly. “Friend with a drink—have one?” And he staggered drunkenly forward, banking all upon the credulity and thirst of the soldier who confronted him with fixed bayonet.

That the sentry was both credulous and thirsty was evidenced by the fact that he let Barney come within reach of his gun. Instantly the drunken Austrian was transformed into a very sober and active engine of destruction. Seizing the barrel of the piece Barney jerked it to one side and toward him, and at the same instant he leaped for the throat of the sentry.

So quickly was this accomplished that the Austrian had time only for a single cry, and that was choked in his windpipe by the steel fingers of the American. Together both men fell heavily to the ground, Barney retaining his hold upon the other’s throat.

Striking and clutching at one another they fought in silence for a couple of minutes, then the soldier’s struggles began to weaken. He squirmed and gasped for breath. His mouth opened and his tongue protruded. His eyes started from their sockets. Barney closed his fingers more tightly upon the bearded throat. He rained heavy blows upon the upturned face. The beating fists of his adversary waved wildly now—the blows that reached Barney were pitifully weak. Presently they ceased. The man struggled violently for an instant, twitched spasmodically and lay still.

Barney clung to him for several minutes longer, until there was not the slightest indication of remaining life. The perpetration of the deed sickened him; but he knew that his act was warranted, for it had been either his life or the other’s. He dragged the body back to the bushes in which he had been hiding. There he stripped off the Austrian uniform, put his own clothes upon the corpse and rolled it into the river.

Dressed as an Austrian private, Barney Custer shouldered the dead soldier’s gun and walked boldly through the wood to the south. Momentarily he expected to run upon other soldiers, but though he kept straight on his way for hours he encountered none. The thin line of sentries along the river had been posted only to double the preventive measures that had been taken to keep Serbian spies either from entering or leaving the city.

Toward dawn, at the darkest period of the night, Barney saw lights ahead of him. Apparently he was approaching a village. He went more cautiously now, but all his care did not prevent him from running for the second time that night almost into the arms of a sentry. This time, however, Barney saw the soldier before he himself was discovered. It was upon the edge of the town, in an orchard, that the sentinel was posted. Barney, approaching through the trees, darting from one to another, was within a few paces of the man before he saw him.

The American remained quietly in the shadow of a tree waiting for an opportunity to escape, but before it came he heard the approach of a small body of troops. They were coming from the village directly toward the orchard. They passed the sentry and marched within a dozen feet of the tree behind which Barney was hiding.

As they came opposite him he slipped around the tree to the opposite side. The sentry had resumed his pacing, and was now out of sight momentarily among the trees further on. He could not see the American, but there were others who could. They came in the shape of a non-commissioned officer and a detachment of the guard to relieve the sentry. Barney almost bumped into them as he rounded the tree. There was no escape—the non-commissioned officer was within two feet of him when Barney discovered him. “What are you doing here?” shouted the sergeant with an oath. “Your post is there,” and he pointed toward the position where Barney had seen the sentry.

At first Barney could scarce believe his ears. In the darkness the sergeant had mistaken him for the sentinel! Could he carry it out? And if so might it not lead him into worse predicament? No, Barney decided, nothing could be worse. To be caught masquerading in the uniform of an Austrian soldier within the Austrian lines was to plumb the uttermost depth of guilt—nothing that he might do now could make his position worse.
