"How are the engines running?"

"Perfectly, sir; never better! They never misfired once, and there isn't a strut or control wire damaged."

"Right!" exclaimed the Commander laconically, who then rolled up the big map, touched a bell, and ordered the aerodrome Flight-Sergeant to run out the machines and to let the air mechanics, observers, wireless men and aerial gunners fall in and stand by the 'planes. Then, turning to the three Flight-Commanders he said:

"Graham, you will take 'A' Flight and patrol the Lestrée line. You, Dastral, will take charge of 'B' Flight and watch the Havrincourt-Bapaume route, and Wilson there will watch the Peronne loop-line. They may come by any of those three routes. Where they will detrain I cannot say. It will be for you to discover. Fill up with the twenty-pound bombs, as they're the handiest, for I expect it will be more of a bombing raid than anything else. But if the enemy is escorted by Fokkers or Rolands, you must be prepared for a fight in the air as well, and I want each Flight to act independently, but if necessary to co-operate, should Himmelman and his crowd turn up. Smoke signals will be the best, I think. Is that quite clear, boys?"

"Yes, sir. Quite clear," they replied, for they were all in high glee, and regarded it all as nothing more or less than a boyish adventure, though more than one of those brave youths was going forth to his death. And what a death it is to be hit in mid-air by bursting shrapnel, and hurled seven thousand feet to the earth! But such a death they faced daily without flinching.

"Then fill up your glasses, boys, and I will give you The King! God bless him!"

And standing up they drank confusion to the King's enemies, and if a stranger had been there to note it, he would have seen that many a glass was filled with water, for the continuous demand upon the pilot's nerve and intelligence forbids his frequent use of alcohol.

Soon afterwards, the pilots, observers and gunners were carefully examining their machines, guns, fixing bombs, waterproof maps, and arranging every detail with care and skill. A faulty strut or control wire, a defective bomb release, or a leaking petrol tank might mean failure or disaster.

At last all was ready, and the final words of command were given to the air mechanics.

"Stand clear! Away!"
