Then Servian victories came thick and fast. Even while batches of Austrian prisoners were being brought in, Servian troops in great strength followed, and there was a daring, magnificent raid across the Save, in which the Austrian monitors were driven out into the Danube and away by the terrific fire of the splendidly handled big guns of the Servians. For two or three splendid days Servian troops held Semlin, before the exigencies of the strategy of the campaign forced them to give up their prize and let the Austrians, now heavily reënforced, reënter their capital city.

"We couldn't stay, but we showed them what we could do, didn't we?" said Stepan, exultingly.

"Yes. But isn't there danger that they may come on now in great force?"

"They are sure to do that," said Stepan, his eyes burning brightly. "It is what we hope. Now the second stage of the campaign will begin. They have already sent great reënforcements into Bosnia, and the army that we and Montenegro sent against Serajevo has had to retire. Remember, Dick, we are not fighting this war alone. Russia is at war, too. It was our aim to compel the Austrians to withdraw many troops from Galicia and Bukowina and the passes of the Carpathians. Now they have done that, and we shall see. They are beginning to advance across the Drina toward Valjevo. We shall see soon what the result is to be."

That prophecy was soon made good. For now the Austrians poured across the northern and western borders of little Servia in overwhelming force, and the Servian armies, muttering, fighting as they went, fell back before them. Behind Belgrade, to the south of the city, the Servian army that had won the great victory of Schabatz gave ground, lest it be taken in the rear by the Austrian advance from Valjevo, and that movement changed the whole aspect of affairs. That army had been the real protection of Belgrade. As soon as it retreated the Austrians marched into the city. But it had taken them five months, instead of as many days, to accomplish their end.

"We are to stay," Stepan had said, when it was certain that Belgrade must fall. And they had stayed, unmolested by the small Austrian force of occupation.


CHAPTER XVII

BETWEEN THE LINES

The Austrian occupation made surprisingly little difference in the outer aspect of Belgrade. The bombardment, which had been maintained spasmodically and at intervals ever since the outbreak of war, ceased, of course. There were a good many Austrian soldiers about, but these were not the trim, soldierly looking men one might have expected to see. Dick commented on this.
