Punch gave a low grunt, raised his head a little, and tried to look round and pierce the darkness, seeing very little though but the fact that they were surrounded by wounded men, for the most part asleep, though here and there was one who kept trying to move himself into an easier position, but only to utter a low moan and relapse into a state of semi-insensibility.

About a dozen paces away, though, he could just make out one of the sentries leaning upon his musket and with his back to them. Satisfied with his scrutiny, Punch shifted his position a little, drawing himself into a position where he could get his lips close to his companion's ear.

"Look here," he said, "can you bite?"

"Bite! Nonsense! Who could think of eating now?"

"Tchah!" whispered Punch, "who wants to eat? I have been wiggling myself about quietly ever since they set me down, and I have got my hands a bit loose. Now, I am just going to squirm myself a bit farther and turn over when I have got my hands about opposite your mouth, and I want you to set-to with your teeth and try hard to draw the tongue of the strap out of the buckle, for it's so loose now that I think you could do it."

"Ah! I'll try, Punch," whispered Pen.

"Then if you try," said the boy, "you'll do it. I know what you are."

"Don't talk, then," replied Pen excitedly, "but turn over at once. Why didn't you think of this before? We might have tried at once, and had a better chance, for it will be light before long."

"Didn't think of it. My arms hurt so that they made me stupid."

Giving himself a wrench, the boy managed to move forward a little, turned over, and then worked himself so that he placed his bandaged wrists close to his comrade's mouth, and then lay perfectly still, for the sentry turned suddenly as if he had heard the movement.

Apparently satisfied, though, that all was well, he changed his position again, and then, to the great satisfaction of the two prisoners, he shouldered his musket and began to pace up and down, coming and going, and halting at last at the far end of his beat.

Then, full of doubt but eager to make an effort, Pen set to work, felt for the buckle, and after several tries got hold of the strap in his teeth, tugging at it fiercely and with his heart sinking more and more at every effort, for he seemed to make no progress.

Twice over, after tremendous efforts that he half-fancied loosened his teeth, he gave up what seemed to be an impossibility; but he was roused upon each occasion by an impatient movement on the part of Punch.

"It's of no use," he thought. "I am only punishing myself more and more;" and, fixing his teeth firmly once more in the leather, he gave one shake and tug such as a wild beast might have done in worrying an enemy. With one final drag he jerked his head back and lay still with his jaws throbbing and the sensation upon him that he had injured himself so that several of his teeth had given way.

"It's no good. It's of no use, Punch," he said to himself; for the boy shook his wrists sharply as if to urge him to begin again. "I can't do it, and I won't try;" when to his astonishment he felt that his comrade was moving and had forced himself back with a low, dull, rustling sound so that he could place his lips to his ear again; and to Pen's surprise the boy whispered, "That last did it, and I got the strap quite loose.

My! How my wrists do ache! Just wait a bit, and then I will pull you over on to your face and have a turn at yours."

Pen felt too much confused to believe that his companion had succeeded, but he lay perfectly still, with his teeth still aching violently, till all at once he felt Punch's hands busy about him, and he was jerked over upon his face.

Then he felt that the boy had raised himself up a little as if to take an observation of their surroundings before busying himself with the straps that bound his numbed wrists.

"Lie still," was whispered, "don't flinch; but I have got my knife out, and I am going to shove it under the strap. Don't holloa if it hurts."

Pen set his aching teeth hard, and the next minute he felt the point of the long Spanish clasp-knife which his comrade carried being thrust beneath one of the straps.

"He will cut me," thought Pen, for he knew that the pressure of the strap had made his flesh swell so that the leather was half-bedded in his arm; but setting his teeth harder--the pain he felt there was more intense--while, when the knife-blade was being forced under the strap he only suffered a dull sensation, and then grew conscious that as the knife was being thrust beneath the strap it steadily divided the bond, so that directly after there was a dull sound and the blade had forced its way so thoroughly that the severed portions fell apart; sensation was so much dulled in the numbed limbs that he was hardly conscious of what had been done, but he knew that one extremely tight ligature had ceased its duty, though he could hardly grasp the idea that one of his bonds was cut.

Then a peculiar throbbing sensation came on, so painful that it diverted the lad's attention from the continuation of Punch's task, and before he could thoroughly grasp it Pen found that the sharp blade had been thrust under another strap, dividing it so that the leather fell apart, and he was free.

But upon his making an effort to put this to the proof it seemed as if his arms were like two senseless pieces of wood; but only for a few minutes, till they began to prove themselves limbs which were bearers of the most intense agony.

_Click_! went Punch's closing knife-blade; and then he whispered, "That's done it! Now, when you are ready, lead off right between those sleeping chaps. Creep, you know, in case the sentry looks round."

"A minute first," whispered Pen; "my arms are like lead."

"So's mine. I say, don't they ache?"

Pen made no reply, but lay breathing hard for a time; and then, raising his head a little so as to make sure of the safest direction to take, he turned towards his comrade and whispered, "Now then: off!"

CHAPTER THIRTY EIGHT.

"HEAR THAT?"

It was still dark, but there were faint suggestions of the coming day when Pen began to creep in the direction of a black patch which he felt must be forest.

This promised shelter; but he had first to thread his way amongst the wounded who lay sleeping around, and his difficulty was to avoid touching them, for they apparently lay thickest in the direction he had chosen.

Before he was aware of what he was doing he had laid his inert right hand upon an outstretched arm, which was drawn back with a sharp wince, and its owner uttered a groan. Bearing to the left and whispering to Punch to take care, Pen crept on, to find himself almost in contact with another sufferer, who said something incoherently; and then a whisper from Punch checked his companion.

"Come on," said Pen hastily, "or they will give the alarm."

"Not they, poor chaps! They are too bad. That sentry isn't coming, is he?"

Pen glanced in the man's direction, but he was not visible, for some low bushes intervened.

"I can't see him," said Pen.

"Then look here, comrade; now's our time. It's all fair in war. Every man for himself."

"What do you mean? Don't stop to talk, but come on."

"All right; but just this," came back in a whisper. "They can't help themselves, and won't take any notice whatever we do, unless they think we are going to kill them. Help yourself, comrade, the same as I do."

Pen hesitated for a moment. Then, as he saw Punch busily taking possession of musket and cartouche-belt, he followed his example.

"It's for life, perhaps," he thought.

He had no difficulty in furnishing himself with the required arms from a pile, and that too without any of the wounded seeming to pay the slightest attention.

"Ready?" whispered Punch. "Got a full box?"

"Yes," was the answer.

"Sling your musket then. Look sharp, for it's getting light fast."

Directly after the two lads were crawling onward painfully upon hands and knees, for every yard sent a pang through Pen's wrists, and he thoroughly appreciated his comrade's advice, for there were moments when he felt that had he been carrying the musket he would certainly have left it behind.

He did not breathe freely till he had entered the dark patch of woodland, where it was fairly open, and they had pressed on but a short distance in the direction of the mountain, which high up began to look lighter against the sky, when he started violently, for the clear notes of a bugle rang out from somewhere beyond the spot where the wounded lay, to be answered away to left and right over and over again, teaching plainly enough that it was the reveille, and also that they were in close proximity to a very large body of troops.

"Just in time, comrade," said Punch coolly, as he rose to his feet.

"Take care!" cried Pen. "It isn't safe to stand up yet."
