It was well they had arranged a proper plan of campaign, else their labour would have been half in vain. Now, with the information which had come to hand by the mysterious Captain Scott, they knew the exact location of the very buildings on which they were about to concentrate their fire.
"Now we're going to be strafed! I thought so!" cried Dastral.
"Phew! We're in for it now!" replied Jock, as the shot and shell began to scream past them, bursting with red spurts of flame, followed by white puffs and black clouds.
Where was the huge powder factory? They were all searching keenly for it now, for the atmosphere was smoky, which was partly their defence, and partly their disadvantage, making it difficult to place their bombs correctly.
It would never do to fail now. They must go lower down and risk the heavy fire from the "Archies."
The T.N.T. sheds, where are they? The nitro-glycerine works, and the huge dump?
Oh, yes, there they were. Not all the smoke could hide them. Not all the enemy's fire could stop those daring and intrepid raiders.
Dastral gave the pre-arranged signal, and each 'plane dived to the objective for which it had been detailed.
"Boom-m-m!" went the first land torpedo.
Yes, the Flight-Commander had found the powder works. A flame of fire shot up hundreds of feet, and the place began to burn fiercely. The "Archies" roared louder than ever.
