Whether Stanley understood or not Blaine was not certain. But just then the stricken man crumpled back again into his former nest at the bottom of the manhole. A slow groan came up.
"Poor chap! He's in misery, no doubt. But I've just got to try this job —"
Just then the Archies began to cut loose, but Blaine went to zigzagging, at the same time increasing his speed, swooping still lower — lower. At last directly over the front train, with machine guns, Archies, and rifles peppering away at him, he let go with one side of his bomb rack. With the sound of the resultant explosion he wheeled and let go the other.
Both racks landed directly upon the leading train loaded, as Blaine suspected, with all sorts of ammunition.
Instantly he pressed the upward controls and his machine darted on towards the rear just in time to escape the tremendous blaze and roar as that string of loaded cars began to explode one after another. The noise, flames and confusion were indescribable. Regardless of the still up flying shrapnel and shot, the daring man turned loose the controls and instantly whipped into place another rack or two of bombs.
By this time he was directly in the path and, right over the long troop train already slowing down to avoid collision with the exploding ammunition train. This in itself was almost impossible, so closely had one train followed the other, a most incautious thing to do.
He felt that his big spread of wings offered too great a bombarding surface to the forces at the crossroads below, but he was bound to finish the job so well begun, no matter what resulted to himself and Stanley.
Still further down he went, and at the pivotal instant began again with the first rack of bombs. Down they flow, crashing upon car after car. Though half conscious of something at his rear and left, he did not dream the cause until, turning, he saw Stanley's pallid face contracting with pain. The observer was shoving forward the second rack into the essential groove for firing. Blaine in his baste had missed fixing it in the notch necessary for accurate discharge. At untold bodily cost to himself Stanley had again risen and completed the task, just in time for the second rack to fall along the rear half of the train, the last bombs crashing into the rear engine pushing the heavy train from behind.
So far as could be seen from above the wrecking of the two trains was complete. Amid the din of exploding munitions rose the cries of hundreds of wounded, dying men, while the debris of the burning wreckage was strewn up and down the single track for a mile or more.
As Stanley sank back again, more deathlike than ever, Blaine put on all his power and strove to rise. Still roared the anti-aircraft guns, the machine guns and the rest of the snipers below; that is, all that were still on the job after the terrifying disaster so deftly accomplished by Blaine.
