Affairs were looking bad for them, even when "Pan" ran out and west with no enemy ahead but with four of them clinging to her flanks and tail and pumping quick bursts at her; but just here came in those two Flights of our fighting scout Squadrons--quite accidentally so far as they knew, actually of set design and as part of the ordered scheme. Six streaking shapes came flashing down into the fight with their machine-guns pouring long bursts of fire ahead of them, and the four close-pursuing Huns left the "Pan" and turned to join up with their scattered companions. Washie left them to fight it out, and turned directly, and very thankfully, for his 'drome. This ends the tale of "Pan," but not by any means of the result of her work. That work, in the shape of jerky but significant reports, was being dissected in the map-hung Nissen hut even before Pip had reached the Casualty Clearing Station; and "Pan's" work (confirming those suspicious photographs) again bred other work, more urgent telephone talks, and Immediate orders. The stir spread, circle by circle, during the night, and before daybreak the orders had borne their fruit, and Flights--Artillery-Observing, reconnoitring and fighting-scout--were lined up on their grounds waiting the moment to go; the Night Bombers were circling in from their second and third trips of destruction on lines of communication, railways and roads, junctions and bridges, enemy troops and transport in rest or on the march, ammunition dumps and stores; in the front lines the infantry were "standing to" with everything ready and prepared to meet an attack; the support lines were filling with reinforcements, which again were being strengthened by battalions tramping up the roads from the rear; in the gun lines the lean hungry muzzles of the long-range guns were poking and peering up and out from pit and emplacement, and the squat howitzers were lifting or lowering to carefully worked out angles. Before daybreak was more than a mere doubtful smudge of lighter colour in the east, the waiting Flights were up and away to their appointed beats, and the first guns began to drop their shells, shooting "by the map" (maps made or corrected from air photographs), or on previously "registered" lines.
