The agitated children pressed about, and the lieutenant tried in vain to keep them off. Some more venturesome than others, after seeing Ralph and Alfred, began to question them. To the relief of the boys they learned that the French out-posts were less than a mile distant.

"Let us make the repairs as rapidly as possible," said the lieutenant.

An examination showed that not only was the control wire cut in two places, but the vertical plane had its pivot shot away, thus accounting for the peculiar action of the lever, which seemed to jam whenever an attempt was made to turn it to the right. Ralph did not know this, while seated astride the body and manipulating the plane, and it was obvious that even though he had succeeded in splicing the wire, it would have been impossible, with the rudder in that condition, to turn by means of the wire controls.

a.s.sisted by the machinist from the garage belonging to the owner of the school, they completed the repairs in an hour, and, hungry though they were, they again went aloft and sailed for their camp, which was reached after an absence of three hours.

They thus had less than a hour to get a hurried meal and prepare to line up with the squadron, to carry out the orders for the movement to the north. They were now going to that section of the fighting line in France where the most intense struggles up to that time had taken place, and where, ever since the opening of the conflict the most stupendous operations were being carried out to gain the mastery.

Imagine, if you can, the sight that met their gaze, as they took their place on the extreme right of the three squadrons, which were about to launch on this memorable occasion. They were about twenty miles south of the city of Verdun. The extreme northern aviation base was not more than eight miles southwest of the city, located on a level plain east of the forest of Argonne, and close to the Aire river, a tributary of the Aisne.

The trip was a short one, as the actual flying distance was less than fifteen miles. Long before they reached the scene of the great camp, they could see the thousands of vehicles, and the hundreds of thousands of soldiers, on the highways, in the fields, and around the villages along the two main railways which threaded their way along the wide valleys between the Meuse and the Aire.

During every mile of the trip they were under the constant vigilance of the officers, who moved them into echelon, formed them into squares, or caused them to trail in columns of two or three, the object being to accustom the pilots to obey and execute signals while in flight.

CHAPTER XI

A FIGHT AND A LANDING IN BELGIUM

The day following their arrival at the field base, as it was called, they found a wonderful change in the order and arrangement of the place.

Everything was done in the most systematic way. So many machines, from each squadron, were told off each morning for certain duties. Those duties were as follows: First, scouting. This meant ascertaining where the enemy was most active; where the batteries were located; noting the movement of troops, and their general character.

Scouts generally operate in pairs, for if it is impossible to signal back from the ships, one continues the work while the other makes a signaling report from such point or points in the rear as will make the information useful.

The next duty is to protect the scouts from interference. This work is carried on by the large ships, which are usually provided with rapid fire guns. They need not, necessarily, be speedy, for they are to keep in touch with the speedy scout ships, the latter of which sail around over a small area so the observations can be carried on as leisurely as possible.

Third come the bomb-throwers, usually heavy-powered machines, generally not armed, as all the carrying power is devoted to the transportation of bombs. These are also guarded by the heavily armed machines. Sometimes, as in the case of the Farman machine, which the lieutenant used, they were used for scouting, and were also serviceable for fighting purposes.

In the early period of the war there were not many pilots capable of doing the duty required in all branches of the service. It was frequently the case that the aviator would command a ship with a gun on it and do double duty, acting as scout, or he would chase and fight an enemy, manipulating the gun while manoeuvering the machine. It was the sort of duty in which Lieutenant Guyon was engaged at the time he was promoted to the command, and supplied with the new type of machine.

Naturally, as commander of the squadron, he was at liberty to take any one he desired in his flights, and as he had a real affection for the boys, he took delight in having them accompany him on many of his exploits. It was the custom for the lieutenant to entrust the piloting of the machine to one of the boys, while he acted as a scout. Frequently Ralph would perform this duty, while Alfred, with his camera engaged, under the direction of the lieutenant, taking such photos as were deemed necessary to supplement the Department maps.

Thus over a month was spent in scouting duty, and, as the weather became somewhat chilly, especially in the evenings, they never went aloft without being well m.u.f.fled up. One morning the lieutenant called out to the boys that they were likely to have a busy day before them, as the weather was unusually mild for the season.

When they arrived at the hangar the machine was already out of the shed, and the lieutenant was busy with the charts in consultation with the officer of the day. Evidently something unusual was afoot, for they waited more than an hour before the lieutenant re-appeared.

"You might wrap up well," he said. "I have ordered a good luncheon, as we shall have a good long scouting area to cover."

"Which way are we going?" asked Ralph.

"Directly across the city, and then to the east. There is some unusually active business going on between this and Metz."

"Think I had better load up the camera pretty well, even though it is a little misty," said Alfred.

"By all means," responded the lieutenant.

It was eleven o'clock before all was ready, when the lieutenant, addressing Ralph, said: "After we pa.s.s over Verdun, going east, we cross what is called the La Pietrie forests. The princ.i.p.al towns we shall visit are Conflans and Briey, both within the German lines. Through those towns are the princ.i.p.al railway lines which supply the enemy forces to the west with provisions and ammunition. We have eight bombs aboard to be used at convenient points. After lightening up the machine by disposing of them we may make a visit to Longwy, a town twenty-two miles north of Verdun. We ought to have good maps of the railroad sections over there."

As they arose the weather was somewhat hazy, so it was difficult to make observations at high alt.i.tudes. They, therefore, ascended at available points, and took a number of snapshots. To the left the Meuse river, and the edge of the forest beyond were distinctly visible, although they were then registering an alt.i.tude of more than 5,000 feet, and were five miles east of the river. To the east was an impenetrable haze, so the lieutenant directed the machine toward the river, and soon the German encampment and lines were visible through Barencourt.

All were on the alert to notice signs of the enemy's machines, for they were now in such a position that the Germans would be most likely to observe them, but there was not an indication that they would be molested. They then turned the machine to the northeast where a bridge was visible in the distance, and the lieutenant shouted through the tube:

"Make for the first bridge; follow the track on this side for a quarter of a mile, so as to give me a chance to aim. Then take the second bridge to the north further on, and in doing so pa.s.s the factory beyond."

"I understand," said Ralph.

The track was reached, and directions followed. Long before they were over the bridge the lieutenant pushed down the lever which released a bomb, which could plainly be seen at first, but they soon lost sight of the flying missile. A moment later the second bomb was released. How long it seemed for even the first bomb to reach the earth! As they were directly over the bridge an explosion was plainly visible. The first bomb had missed the bridge, but before they had time to comment on it the second one burst at the end of the bridge, and one of the spans went down.

[Ill.u.s.tration: _A Dangerous Position_]

The factory was now in view. "Go down lower," shouted the lieutenant.

Alfred nudged the lieutenant, and pointed to the north. "That looks like an airship," he said.

"So it is," replied the lieutenant, after a hasty glance. "But we must attend to this little business first," he continued, as his foot was extended down to the bomb dropper.

"You have hit it!" shouted Alfred in glee. "Now for the other bridge."

They were not as successful with the last structure, although three bombs were expended on it.

"Now, where is the flyer you saw?" asked the lieutenant.

"It went easy just before we reached the second bridge," said Alfred. "I don't see it now."

"Then I suppose we shall have to go to Longwy to find where it is," said the lieutenant. "Can you see the city beyond?" he continued, pointing to the north. "Go to the left of the city," he said through the tube.

"Why did you tell him to go to the left?" asked Alfred.

"In that way we can avoid the long range aircraft guns, which we know are mounted in the forts to the east of the town," was the reply.

They were soon on the northern side of the town, and in looking south they were surprised to see two machines, one making for the east and the other seeming to fly directly toward them.

"That fellow will be a little surprised when he finds what he has to deal with," said the lieutenant with a chuckle.

"It's a Fokker, isn't it?" shouted Ralph through the tube.

"Quite right; when I give the signal turn to the left, and describe a sharp circle. I'll fool him," said the lieutenant.

The signal came; the machine veered around just as the Fokker came plainly into sight. As the turn was made the lieutenant turned the machine gun to the other side, and when the sight was cleared past the wings he gave the first turn of the crank to the gun.

There was a hum and a succession of cracks, which seemed to surprise the man in the Fokker. He evidently thought that the French machine was trying to get away, or it never would have ventured so close.

"The other machine is coming!" cried Alfred.

"Here is where we can get in the fun," said the lieutenant. "Make a straight line for the one coming up in the east. Go on until I signal."
