The senior office emphasized the last by rapping a clenched fist on the desk.

"Then you know what they're up to, sir?" Dawson asked quickly. "I suppose the colonel told you that we sighted them off shore? Is their base near here, sir?"

Dawson would have asked more questions, but the major general raised a hand for silence and looked at Colonel Welsh.

"Do you want me to do the talking, Colonel?" he asked. "Or would you rather?"

"No, go right ahead, sir," Colonel Welsh replied with a shake of his head. "After all, you've been right here where it's all been going on. Go right ahead, sir."

Major General Hawker grunted and stared down at the desk top for a moment, as though taking time out to choose his words. Presently he looked up at Dawson and Farmer. Both youths were a little startled by the glitter of seething anger in his eyes.

"The North African campaign has progressed so rapidly and so successfully," he began, "that we're way ahead of ourselves, you might say. I mean that we've been so busy doing the big things that we've had to let much detail work slide. For example, this base wasn't to be ready for another month yet, but it is in operation right now. It has been for the last three or four weeks. However, it is simply a port through which equipment and personnel pass on the way to the battle fronts. The working staff is very small, and we have no squadron, or even a flight of planes and pilots of our own. I mean, based here for our protection. That, of course, is because every plane and pilot is needed at the front. Those of us who are behind the front must shift as best we can, until there comes a lull in the main battle, and we've the time to start tucking in the ends."

The major general paused for breath.

"So far, I've only given you a picture of conditions here," he continued presently. "Well, about ten days ago I was secretly informed through Colonel's Welsh's office that the President and Mr. Churchill were going to hold a war conference here at Casablanca. Naturally, I kept that secret. However, the Nazis must have got hold of that news somehow, either here or in Washington. We'll probably never know which. Three days ago those Junkers long-range bombers started putting in an appearance. At first, I thought they were after convoys, but pilots who sighted them off shore reported that they either kept at a safe distance, or raced away to hide in the clouds before our planes could reach them. In short, they did everything in their power to avoid air battle. In addition, they went the limit to prevent any of our planes from following them back to their base."

"Just what do you mean by that, sir?" Dawson asked with a puzzled frown.
