"No, I don't," he said. "I mean that that's the headquarters base for a lot of spots in this section just like it, only we haven't seen them. And, by good luck, we didn't stumble into them since leaving our burned up Skua."

Dave started to nod, then checked himself and gave Freddy a perplexed look.

"Don't look right now," he said, "but you're getting me all balled up, my friend. Just what are you driving at, anyway? Come clean with the works; then maybe I'll argue with you."

"It's quite simple," the English youth said with a faint smile. "You just mix a little imagination with what facts you know, and there you are."

"Maybe you are, but I'm not!" Dave grunted. "Skip the imagination part and just give me the facts."

"Right you are," Freddy said, and started counting off the fingers of one hand. "First, British Middle East High Command knows that troops, planes, and supplies, and so forth, have been transported across the Mediterranean to Tripoli by air and water. Two, High Command knows that it is mostly Nazi stuff. Three, it is obvious that preparations are being made for a drive to beat back Wavell's forces. Four, it is equally obvious that the enemy knows that Wavell's forces are not very strong. As Group Captain Spencer said, everything that could be spared was yanked away and sent down south to hand the Italians a quick mop-up knockout blow in Ethiopia. Five, the one important thing in desert warfare is surprise—surprise attack. Six, if the Axis forces simply started along the main coast road from Tripoli and around the southern end of the Gulf of Sidra, Wavell's outposts, to say nothing of his planes, would spot them long before they were within attacking range, and there would be no surprise at all. You want me to continue?"

"Sure, stay in there and pitch," Dave nodded with a grin. "I know you've got something, kid, and I want to hear it all. I really mean that."

"Very well, then," Freddy said, and started counting his fingers over again. "Seven, to move a huge attacking army down toward the south and back up toward the north would be much too exhausting for the troops, and such an army would be spotted by Wavell's pilots days ahead of time. R.A.F. bombers would then sail out and bomb the stuffing out of the advancing armies."

"Just a minute," Dave cut in. "They wouldn't be dumb enough not to have air protection of their own."

"Correct," Freddy said, and made a little gesture with one hand. "But where would that air protection base itself in this part of the desert? Certainly not with the armies as they moved forward a few miles each day. At Tripoli? And keep flying way out here to guard troops and tanks and other motorized equipment on the move? Not a bit of it, Dave. They might just as well send General Wavell a letter telling him they were creeping up for a surprise attack! They'd—"
