Again we both wheel to the combat. This time he is on top of us. We give up hope, and prepare for the worst. On the top of us again; his shooting is bad, but he has got the observer in the arm. Turn round to escape--no combat possible with the man at the gun _hors de combat_; but the observer, plucky fellow! does not know the meaning of defeat. He signals to his pilot to carry on. We turn again. The enemy is confident that he has winged us. Too confident! We wait till he is almost level with us before we fire. Then zipp, zipp, zipp, he is hit. He plunges downward. We get on top of him. Another round of lead into his back. It is all over, he plunges headlong to earth; and with a feeling of regret for our gallant foe, who fought so well, we turn homewards to earth, peace, and safety. CHAPTER XX A BATTLE FROM ABOVE _Somewhere in the North of France, Thursday._ Dawn--not as we imagine it; but a dawn with God’s clear Heaven filled with every winged messenger of death. The very earth is shaken with agony, and the face of the sun is blotted out by heavy, choking clouds of picric smoke that hangs and hovers over the earth like a pall. Far in the background rises a battle aeroplane. Nearer and nearer to the line it creeps, and without any attention from the enemy’s anti-aircraft guns. The German artillery is too much engaged in work of a more serious nature--the work of hurling back the irresistible lines of British infantry. The frail craft passes over the lines, and meeting with no opposition sinks lower in long, sweeping circles, and finally appears to hover, as nearly as an aeroplane can hover, some two miles to the east and well over the enemy’s country. Then it is bombarded on all sides with “Archibalds,” now above, now below, now immediately in front, now immediately behind, but the machine continues to maneuver as if entirely oblivious of shell fire. Other swiftly moving shapes have now crept out from the direction of the British base, and all are hovering over different portions of the long line of muddy trenches, while the battle rages in all its fury. All the varied operations of the extensive battle-field are as an open book to the watch in that frail craft ... the battle swaying backward and forward from trench to trench, the hand-to-hand combat in the open, the ding-dong artillery duel, and the hurried rush of supports and reinforcements. Nothing can be hidden from this peering eye above, that transmits the news by wireless to the great guns far in the rear, and to the headquarters, where the commander traces every movement of the battle on his map, like a chess-player planning his moves and counter-moves on a chessboard.
