Having arrived, after ten minutes' chat with the officer belonging to the secret service, his first words were: "Grenfell, ask Flight-Commander Dastral to come down at once." "Yes, sir." And on his next journey, Brat fetched Dastral down from his bunk at the mess to join the party. "Dastral," was the first word from the C.O. as soon as the daring young pilot entered. "Yes, sir," replied the Flight-Commander, saluting smartly. "Here's something for you after your own heart." "What is that, sir?" asked the youth, smiling. "The promised raid on Krupps'. How would you like to undertake it with your flight? You have often spoken about it." "Nothing would please me better, sir." "And the other fellows belonging to your flight, what about them?" "They would follow me anywhere, sir!" "Gad, I believe they would, for they all worship you. I believe they'd follow you to 'Gulfs,' if you led them there." Dastral laughed, and repeated his avowal, that he would be only too pleased to start at dawn should the weather conditions prove good enough. "Right!" exclaimed the major. "Then, you'd better spend the next two hours with Captain Scott here, and with your men. Get thoroughly hold of these plans, and fix them in your mind." So, while breakfast was laid for the Intelligence officer, Dastral got his men together, including Mac and Jock. Afterwards the eight men who were going into action carefully laid their plans, arranging a code of signals and the method of attack, should they succeed in reaching their destination. Then they went over to the sheds, examined and tested the machines, saw them loaded up with bombs and drums of ammunition. The guns, compasses, etc., were then shipped and everything was ready. Dastral looked at his watch. In an hour it would be dawn. "We must be off, boys. We must cros the German lines before daybreak." "Right, sir," replied the others, "We can be ready in ten minutes." Then, having previously breakfasted, they put on their thick leather coats, pilots' boots and helmets, and made ready. The C.O. came down to wish them godspeed and a safe return. The probable time of their return was fixed, and it was arranged that an escort should meet them on their way back to defend them from hostile aircraft, lest any of them should be in difficulties, and unable, through damaged machines or lack of ammunition, to fight their way home. "Stand by! Contact, switch off!" came the order. The propellors were swung vigorously once or twice, then, one after another, the engines broke into their mighty song, and the machines taxied off into the darkness across the aerodrome, and as the joy-stick was pulled over each 'plane sprang into the air, and began its long voyage. "Good-bye, and good luck!" shouted the C.O. as each man taxied off, and as a parting salute, each pilot raised his gloved hand from the controls for an instant.
