ery failed to respond to the emergency. The wireless-telegraph system broke down on every vessel, and out of this fact arose the curious discovery that among the obscure gases generated by exploding thorite in the upper atmosphere was one that arrested the wave action of an electrical discharge. The signal-readers were unable to take off the Lietke-ray readings among all the aerial disturbances, so that each vessel remained isolated, and acted on its own initiative. Prince Friedrich, who commanded the fleet from the deck of the flagship Die Schwalbe (the second in line, and now a mile removed from her nearest support), failing to discover any sign of open attack, at once decided to sail away at full speed from so disastrous a spot, and to wait until daylight enabled him to operate prudently. This order was indeed signalled from Die Schwalbe by means of her searchlight, but in the multiplicity of lights and cross-lights the significance of the flashes passed unrecognised. Der Geier and Der Fliegende Fisch therefore remained, pressing to their service every device for repelling attack which they possessed, while Die Schwalbe stole away to the northwest, silently, and with every light obscured.
From the details supplied by the invaders who survived the battle of Elmstead Down it is generally surmised that the second wingman in the line of attack—the one through whose defection Die Schwalbe was able to slip away untouched—was probably struck by a flying fragment of Die Wasser-jungfer, and at this point in the fight a second mishap weakened the successful chance of Reed's desperate venture.
In the uncertainty of their position Der Geier and Der Fliegende Fisch had drawn closer together when the fourth and the fifth wingmen simultaneously swept into the effective range of their lights and rifles. The changed position of the air-ships gave them a moment
