"Who knows?" he said quietly. "We'll have to leave something to chance."

"And Miss Ellison?"

"A uniform for her also," said Hal decisively. "It's the only way."

"But--"

"Oh, I know it is a desperate chance," exclaimed Hal. "But certainly it is better than sitting down and awaiting the arrival of the firing squad."

"You're right, Hal," said Chester. "But it's a ticklish business and one that will require nerve."

"It's not a question of nerve, when you know what's in store in the morning," said Hal. "But as this is my plan, I'll do the work, or what part of it I may."

"You're the doctor," Chester agreed.

"Now," said Hal, "we'll try and get a little sleep. We can do nothing until after dark, and the better our physical conditions, the better our chances for escape."

CHAPTER XXVIII.

THROUGH THE NIGHT.

Hal, Chester, Colonel Anderson, Nikol and Ivan slept. The first three, veterans of many campaigns and hardships, had schooled themselves to sleep under almost any conditions. The same might be said of Nikol and Ivan because of days spent in the mountain fastness, where danger lurked at all times.

Stubbs, however, although he bore up bravely under the death sentence, was unable to sleep, try as he would. Nor could Helen gain a much needed rest, though she was not conscious that she was at all afraid. So these two talked during the long hours of the day as the others slept peacefully and deeply.

With the coming of darkness a man entered bearing a tray with bread and water. The others awakened now and all did full justice to the frugal meal. Their hands were untied while they ate, but the meal over, they were bound again.

Then all waited for what seemed hours, though in reality it could not have been more than three. Then Hal addressed Nikol.

"Still think you can break your bonds?"

"I can," replied Nikol quietly.

"And you, Ivan?"

"Yes, although it won't make much difference. Nikol could release the rest of us."

"I thought the second tying-up might have made it impossible," said Hal.

"I'm ready any time you give the word," said Nikol.

"Then do it now," said Hal.

The others gazed curiously as Nikol made his little form still smaller.

He drew in his chest as much as possible and then expanded suddenly, at the same time thrusting out with his strong arms. There was a report as of a revolver being discharged, though much fainter, and Nikol was free.

"Ha!" said Ivan. "He did it. Now watch me."

The mighty muscles of the giant strained once and the strong rope snapped. Ivan did not seem to have exerted himself.

"Now for the rest of us," said Hal.

Quickly Ivan and Nikol released the others.

"Now what?" asked Ivan.

"Now comes my work," said Hal quietly.

He moved silently to the edge of the tent and lay down flat, feeling the edges with his fingers.

"This will come up all right," he muttered to himself. "I can get out here."

He went back to the center of the tent again and enjoined the others to silence.

"Don't make a sound on your lives," he commanded sternly. "Chester, you remain right where I leave the tent and if I bring a man back with me you drag him under and see that he doesn't make a sound."

Chester nodded his agreement and took his place at Hal's side.

Now the lad lifted the bottom of the canvas slightly and peered out. He smiled a trifle to himself. It was as he hoped. The guard or guards, as the case might be, was not as vigilant as the security of the prisoners should have required. Hal wriggled into the open.

The huge camp slept. Here and there a sentinel stalked and it was upon these guardians of the night that Hal must prey.

He moved toward the front of the prison tent, seeking the guard there.

And directly he came upon him, stretched at full length upon the ground, his heavy military coat pulled closely about him, smoking a cigarette.

Hal moved toward him cautiously.

"I hate to do this," he muttered, "but--"

With a light leap he was upon the man and his right fist shot out hard and true. It caught the Bulgarian just above the left ear and the man never made a sound.

Quickly Hal dragged the body to where he knew Chester would be waiting.

Chester dragged it under the tent and Hal went under after it.

"This uniform is for me. I'll go after some more," he said.

Quickly he climbed into the Bulgarian uniform and disappeared again. But this time, garbed in a Bulgarian uniform, he went more confidently. His hand rested upon his revolver.

A short distance away he came upon an unsuspecting sentinel. A sharp blow with his revolver b.u.t.t placed the other _hors de combat_.

Supporting the unconscious figure with his arm, Hal moved back to the prison tent. This figure also was pushed beneath the canvas and the uniform donned by Chester.

"Now we can make a little better time," said Hal, "there are two of us."

Uniforms were still needed for Colonel Anderson, Ivan, Nikol, Stubbs and Helen. Hal and Chester disappeared into the night.
