CHAPTER XXVI.

IN GRAVE PERIL.

Helen led the way to the roof, the others following closely. As Hal had predicted, it was possible from this height to obtain a fair view of the opposing armies.

To the north, as far as the eye could see, the army of King Ferdinand of Bulgaria spread out, a mass of moving energy. Faint puffs of smoke dotted the Bulgar line as far as the eye could see.

"Cannon!" said Hal briefly.

To the south, the Serbian line moved forward. It, too, spread out on either side as far as the eye could reach and puffs of smoke rose steadily, shutting out the view of the moving men.

"More cannon," said Chester.

"We seem to be safe enough for the moment," said Hal. "The shells are passing over us. But if one side or the other should advance as far as this house, we would be in imminent danger of being struck by shells from the other side."

"Well, one side is bound to advance sooner or later," declared Chester; "but I guess there is nothing for us to do but wait and watch the progress of the battle."

"You fellows can watch all you want to," said Stubbs. "I'm going down stairs where I won't be able to see a shell coming."

"It won't make much difference whether you are up here or down there if a shell hits this house, Mr. Stubbs," said Chester.

"Maybe not; but I won't see it and that will help some."

Stubbs betook himself below.

"Don't know what is coming over Stubbs," said Chester. "He didn't use to be as bad as that."

"He was when we first met him," Hal replied. "But he seemed to be getting over it. He's worse than ever now."

From their position, those upon the roof of the house could witness the effect of some of the great shells that were hurled into the opposing lines. One, from the Serbians, struck squarely upon the Bulgarian first line troops, doing terrible execution. Men were mowed down in great numbers.

A few moments later the Bulgarians also found the range and the havoc was frightful on each side.

"They can't stand that very long," said Hal. "One side or the other will have to make a move."

The lad was right; and as it transpired the first move was to be made by the Serbians.

So suddenly that it appeared the work of magic, a great body of horsemen, stretching out for perhaps half a mile, issued from the Serbian line in a charge. On they came, their sabers flashing in the early morning sun, straight for the distant Bulgarian line.

Chester gave an exclamation of dismay.

"They'll pass within a short distance of us," he ejaculated. "Then the Bulgarians will turn their big guns on us." He turned to Helen. "You would better go downstairs, Miss Ellison," he said quietly.

"But I want to see the battle," the girl protested.

"Chester is right," Hal agreed. "This is no place for you. Bullets are likely to be flying about here before long now."

"But the rest of you are not coming down?"

"That's different," said Chester.

"I don't see how. A bullet is no more liable to hit me than it is to hit you."

"Well, of course if you insist, I won't push you down," said Hal, somewhat nettled.

Helen Ellison tossed her head.

"Of course if you are going to be mean about it, I'll go down and sit with Mr. Stubbs," she said.

Without another word she disappeared below.

Hal looked at Chester and smiled.

"Women and girls," he said, "are very peculiar. As soon as you agree with them they change their minds."

"Well, she's down, anyhow," said Chester. "That's some relief."

"And here come the Serbians," said Hal.

A handsome body of men, these Serbian cavalrymen, as they charged straight across the open field into the very jaws of death. Men fell on all sides, but those who were left did not pause. The command had gone forth that the Bulgarian guns must be silenced and the Serbians went about the work as coolly as though they had been on dress parade.

But it appeared a few moments later that the battle was not to be between horsemen and artillery, but rather between cavalry and cavalry.

From the Bulgarian lines now issued a large body of horsemen; and they came toward the Serbians at a swift gallop, their officers riding in front with swords flashing and urging their men on with words of encouragement.

The Serbian cavalry, at a command, halted and braced to receive the shock.

"Great Scott! What did they stop for!" exclaimed Hal. "They are giving the other fellows, all the advantage when they come together."

"Looks like bad generalship to me," Chester agreed.

Now, at a command from their officer, the Serbians resumed their charge; but the damage had been done and when the long lines of opposing horsemen came together the very impetus of the Bulgarian charge carried them through. The Serbians reeled, staggered and their line broke.

The Bulgarian horse plowed in among them, cutting, slashing and stabbing. Individually, the Serbians fought as bravely as their foe, but in spite of the desperate work the Bulgarian cavalry retained its cohesion and pushed steadily on.

The fighting was terrible to behold. Revolvers were brought into play and their sharp crack, crack could be heard above the sound of the trampling horses and yelling men. It became apparent to the onlookers that the Serbians were getting the worst of the encounter.

Casting his eye toward the main Serbian line, Hal gave a short cheer. A long, dense line of infantry was moving out to the support of the cavalry. Slowly they came at first, then faster and still faster as the men broke into a run. An imposing sight, indeed, and one to stir the blood. The Serbian cavalry, at a command, fell back upon the infantry, which separated into two sections to permit of the cavalry passing through the center. Then the infantry closed in again.

But the Bulgarian cavalry, with victory apparently within its grasp, had no intention of giving up now. With utter recklessness they charged the Serbian infantry, dying bravely before the rifles and upon the bayonets of their enemy when they chanced to escape the rifle fire.

The Serbian line held like a stone wall.

Then the Bulgarian cavalry drew off. A cheer, which arose from the
Serbian line, was quickly checked as the giant batteries of the
Bulgarians opened upon the unprotected Serbian line. The Serbians
wavered, broke and fled.

Then once more the Bulgarian cavalry wheeled and charged. Right into the dense masses of Serbians rode the troopers, cutting and slashing to right and left. The execution among the panic-stricken Serbians was terrible to behold.

"They can't stand it long," Hal shouted, barely making himself heard above the roar of battle.

"The day is lost already," Chester shouted back.

There seemed no doubt of that now.

What was left of the Serbian infantry staggered back to the main army shattered and beaten. The big guns took up the battle again, but not with the same vigor and confidence as before. The Serbian fire seemed even to tell the spectators on the housetop that the Serbians had lost hope.

Half an hour later a general retreat began.

"Bad generalship, that's all," declared Hal.

"Without doubt," agreed Colonel Anderson. "A charge is a charge and once begun must be finished. That was where the Bulgarians gained the whip hand."

"The next step, I suppose, is an advance by the Bulgarians," said
Chester.

"Very likely," Hal agreed, "and that means that we shall be caught in the
Bulgarian lines."

"It means worse than that," said Colonel Anderson. "We are all in civilian attire and if our identities are discovered, it means that we'll be stood up and shot."

"By Jove!" said Hal. "I hadn't thought of that."

"Oh, we've been in predicaments just as serious," said Chester, "and we have always come through somehow. I guess we shall do so again."

"We'll get into one just once too often, I'm afraid," said Hal, "and this is likely to be it."

"You're getting as bad as Stubbs, Hal," said Chester. "Just keep a stiff upper lip and we'll come through this thing some way."

"I'm no quitter," said Hal. "But the best we can do now is let events shape themselves."

And now the Bulgarian advance began.

Apparently the Bulgarian commander had no thought of attempting to overtake the Serbians and annihilate them. Apparently he figured that ground gained was ground gained whether with or without a fight. The army moved forward slowly.

A party of officers, following in the wake of the vanguard, rode suddenly toward the house in which the friends had taken refuge.

"And here comes the trouble, as Stubbs would say," declared Hal. "Let's go below and get ready to receive them."

He suited the action to the word and the others followed him silently. Below, Hal acquainted Helen with what had transpired and announced that the Bulgarians were approaching.

"And what of the bodies without?" asked the girl quietly.

"Whew!" Hal gave a long and expressive whistle. "I hadn't thought of that. Wait a moment, though. We'll have to say they were here when the Serbians advanced and were killed."

"But the Serbians were not so close to the house."

"I know that, but I cannot think of any better excuse."

"Besides," said Stubbs, "if the Bulgarians were killed here by the Serbians, the chances are the Bulgarian commander will want to know how it happens we weren't killed also."

"Stubbs," said Hal, "I told you you were always a kill-joy. You can pick more flaws in things than any one I can think of. We'll tell the Bulgarians that story and take a chance on its passing muster."

"Then we may as well say our prayers now," said Stubbs mournfully.

"But what will we tell them we are?" asked Chester.

"Americans," replied Hal. "Caught here by the retreat. We were just making our way out of the country. I'll do the talking."

"All right," said Chester, and added: "Sh-h-h, here they come now!"
