One or two Taubes and Aviatiks which had been out on a reconnaissance and for a few photographs, rapidly retired before the hornets and fled to find shelter somewhere beyond. Meanwhile, the telephones in the German lines were busy and the presence of the raiders was quickly reported to the various commands, and from thence to half a dozen aerodromes. Machines were rapidly run out, and got ready to mount up and meet the invaders, for it was evident that the perfidious Britishers had resolved to carry out another great bombing raid on railway communications, billets, and ammunition dumps. Within an incredibly short space of time, Himmelman himself had started to meet the the enemy. But the raiding party swept on, beyond Bazentin, Ginchy and Longueval, bombing, as they passed, Combles and the Peronne railway. Soon, they sighted the aerodromes at Scilly and Etricourt, and bombarded them, receiving another crackle of fire from the A.A. guns posted to defend the hangars and sheds. Then, wheeling north they scattered a large transport column which was proceeding slowly along the main road from Le Transloy to Bapaume. Shortly afterwards, a swift circling movement and a smoke bomb from the leading 'plane gave the signal: "Enemy 'planes approaching!" All this had been accomplished within half an hour of crossing the enemy's lines, and the Germans had been caught fairly on the nap. But now Himmelman had got his machines in motion, and a fight in mid-air could not be much longer delayed. The English pilots looked down, and far below they could see from half a dozen places Aviatiks, Taubes and Rolands creeping up to the attack. By this time all the heavy missiles had been dropped, and the machines, with their engines running superbly, had gained something in buoyancy from the release of the half dozen 20-pounder bombs, with which each aeroplane had started. Guns were now cocked and loaded, and the discs were clapped into place, while extra drums were placed where they would be most handy, for when the fight commenced, a delay of five seconds might prove fatal. Then a bold attempt was made to get the weather-gage, and to use their advantage in altitude to place the sun behind their backs, so that the enemy would have it in his face. Every type of aeroplane approaching was carefully scrutinised, and, with sundry circling dips, short nose-dives and smoke bombs, the Squadron-Commander told off various machines to fight them, for every type of machine has its own special capabilities and limitations. At the same time the heavens were eagerly scanned for a sight of the hated Fokker. "Where is Himmelman? Where is Dastral?" every keen-eyed pilot was asking himself. And every little cloud above and beyond was searched, but no sight of the air-fiends was vouchsafed. Ah, well, they must fight without Dastral if he had not yet picked them up.
