The Yank air ace cut himself off short, leaned forward and peered out through the window glass on his side.

"See something?" Squadron Leader Hixon inquired casually.

Dawson didn't reply for a moment. He thought he saw something on the surface of the water a few miles ahead and a couple toward the north. It seemed to disappear from view, however, when he strained his eyes. Then, suddenly, he saw it again, and his heart leaped up in his throat to hit hard against his back teeth. Without taking his eyes off the distant object, he reached and rapped Squadron Leader Hixon on the arm.

"Take a look up ahead there, and a couple of degrees to the north, sir!" he cried out. "That looks to me like a submarine on the surface. Yes, it is. But I can't tell from here whether it's one of theirs or one of ours."

"By Jove, you're right, Dawson!" the Squadron Leader's voice boomed close to Dave's ear. "A sub, right enough. And not making headway, either. It's—Oh, blast our luck!"

"What do you mean?" Dawson shot at him.

"Not a U-boat," the pilot said with heavy disappointment in his voice. "Can tell from the shape of the conning tower. It's one of our undersea boats. Should know I'd never have the luck to come across one of Hitler's U-boats on the surface like that. I'm—I say! Seems to be a bit of trouble, what? They've sighted us and sent up a signal."

Dawson didn't make any comment for the moment. His gaze was fixed on the submarine awash on the surface, and he saw the red distress flare arc up into the air from the conning tower bridge. Squadron Leader Hixon had changed course and was drilling the Lockheed Hudson down across the sky straight toward the motionless submarine. In a matter of seconds Dave was able to see the groups of men on the bow and stern decks. And as a second and a third red distress flare arced upward, he saw the men on deck start waving their hands wildly. And a split second later he saw a thin column of smoke come up out of the conning tower hatch.

"Trouble is right!" he grunted. "Must be a fire inside, which forced them all up top-side. Nothing we can do for them, though, is there, sir? This Hudson can't land in the water to pick them up."

"Certainly can't!" the pilot grunted with a frown. "Too many of them, anyway, even if we could. The chaps are just out of luck, too. My orders are for radio silence, regardless. I can't even send out a flash to any of our navy boats that may be close by."
