"Bravo! Well done, boys!" yelled the leader, waving his hand to the daring men behind. For they had outclassed the Boche, and before he could rectify his aim, the machines were out of range once more.
On the other side of the town, however, they came in for the same treatment, but they once more evaded the enemy's fire, and soon they left the town of Coblentz, with its Denkmal of Wilhelm der Grosse, and the forts of Ehrenbreitstein behind them.
"Three hundred shots for nothing, Jock," shouted Dastral, who was highly pleased with himself.
Jock did not hear, however, for the wind carried the words away, and the observer was otherwise engaged, searching the skies with his glasses. A moment later, however, having discovered what he was looking for, he turned and shouted:
"One, two, three of them climbing to attack us!"
"Where are they?"
"Down below there to the left. Two yellow fat 'planes with black crosses on them, and a white one."
Dastral looked serious for a moment, as, holding the joy-stick with his right hand, he raised his glasses with the other and looked down, to where, from an aerodrome just by the river, three enemy 'planes were rising up to fight with them.
The shadow passed from the fair, young face of the chief pilot, as he gazed upon the enemy, and a calm smile wreathed his face.
"Humph! Let the devils come. We are not afraid of them. Sorry I can't stay to fight them, Jock. Our first business is to bomb the arsenal, not to pick a stray quarrel with these beasts, who are asking for trouble."
