He started when he heard the Generalissimo's order, for even yet he could not be sure, but the dots had now grown so large that it was possible to tell the make of the two machines, and somebody said: "The first one is an Aviatik; the other is a Fokker."

If the seeming chase were a piece of German stage management it was certainly being carried out with marvellous realism, for now Martique could distinctly see the puffs of the machine-gun, and that the bullets were ripping through the lifting planes of the Aviatik.

"Mon Général!" he cried suddenly, "for the love of heaven order our battery not to fire! Look! The observer in that machine is waving a French flag. He has dropped it now, and he slues his gun into position—but with one arm only! He is wounded!"

"Do you know what you are talking about, young man?" said the Generalissimo sternly.

"Forgive me, mon Général!" faltered Martique. "It was a little secret. Oh, look! The Fokker has got the top place, and is about to ram poor Laval and his English companion!"

Everyone held his breath, for indeed it was as Martique had cried. The Aviatik was volplaning down in a wide spiral now, and above it the relentless pursuer poised like a hawk. He was judging the circumference of those spiral curves, and even the Generalissimo himself tightened his lips under the huge white moustache.

Over the side of the fuselage there was no mistaking the glorious red, white and blue that fluttered wildly in the descent, and then the Aviatik's swivel-gun spoke three times. A German always speaks French badly, but that German gun rang out with a true accent that time, and the Fokker gave a strange quiver, burst into a sheet of flame, and dropped like a stone to death and destruction six thousand feet below!

The engines of the Aviatik ceased; the nacelle, pointing earthwards, curved suddenly up again, and floating for some distance like a tired bird, the machine dropped out of sight on the other side of the tall poplars.

There was an instant stampede to the spot, the Generalissimo himself following, unable to curb his curiosity; but as he reached the bank at the edge of the cornfield a running figure in leather jacket and flying helmet checked his pace and, throwing up his goggles, saluted smartly.

"Mon Général, I hope you will accept my apology," said Dennis Dashwood. "I am five minutes behind my time, but I am here, and I have a good deal to tell you!"
