That they were effective tactics was promptly demonstrated to the Huns by one of their machines bursting into flames, another rolling over sideways and "dead-leafing" down in a series of side-to-side slips which ended in a crash on the ground below, and by another continuing his dive well down, changing it into a long glide to the eastward and out of the fight, evidently with machine or pilot out of action. Several of the Fo-Fums had bullet-holes in their machines, but nothing vital was touched, and they had just time to connect up nicely into their compact circle when the remainder of the Huns came tearing down on them in similar terrifying fashion. But the Fo-Fums met them in their similar fashion, and when the Huns, instead of diving past and down as the first lot had done, curved up in an abrupt zoom, the observers swung their gun-muzzles up after them and pelted them out of range. One Hun lost control just on the point of his upward zoom, flung headlong out until he stalled and fell out of the fight for good. From the fact that his gun continued to fire at nothing until he was lost to notice it was evident either that his gear was damaged or the pilot hit and unconsciously gripping or hanging to the trigger or firing mechanism. A fourth Hun at the top of his zoom up lurched suddenly, fell away in a spinning nose dive, and also vanished from the proceedings--whether "crashed" or merely "out of control" was never known. In a fight against this sort of odds, which our pilots so often have, the need of keeping an eye on active enemies rather than on the subsequent interesting fashion of an out-of-control's finish certainly reduces our air men's score a good deal, since it is the rule only to claim and record officially as a "crash" a machine which is actually seen (and confirmed) to have smashed on the ground, to have broken in air, or otherwise have made a sure and positive finish. Five Huns down and definitely out of action was a good beginning to the fight, especially as no Fo-Fum was damaged, and the odds were now reduced to fifteen against six--quite, according to the Fo-Fums, usual and reasonably sporting odds. But the odds were to lengthen to such an extent that even the seasoned and daring fighters of No. Umpty Squadron began to look grave and feel concerned. Two Flights came looming up rapidly from eastward, and, occupied as the Fo-Fums were with the first brush, the new enemies were upon them almost the instant the second rush on them finished--before, in fact, the first Huns shot down and hit the ground. The newcomers converged on the fight and dashed straight at the Fo-Fum circle without a pause. There were twelve of them in one lot and eight in the other, and that, added to the twenty the Fo-Fums had counted at the beginning of the fight, made a total of forty machines against their six.
