The Japs called again that night. This time the “cards” that they dropped were shells from a cruiser that had sneaked close to the shore, in the dark hours. Five miles away, she let loose with her heaviest guns. Her aim was surprisingly accurate. To the Rosy O’Grady’s crew, the stuff seemed to be exploding all around their tent.

The screaming of shells, each followed instantly by an earth-shaking blast, produced a nightmare of horror for the unseasoned men. Not one of them gave way to fear, however. The most upset man in the tent was Tex O’Grady, who paced up and down between the cots, worrying about his ship and fighting mosquitoes. He couldn’t get Rosy into the air, because the field had no lights as yet.

“If I knew this confounded field better,” he fumed, “I’d take off and get her safe upstairs. But except for those shell flashes it’s as dark as the inside of a cow. I’d only ground loop—”

WHANG!

A shell burst, nearer than any before it; tossed chunks of earth through the open flap. Some dirt must have struck O’Grady in the mouth, Barry guessed, from the way the Old Man sputtered and spat.

“Better get your head down, Captain,” Curly Levitt spoke up. “You’re not as big a target as Rosy, but you’ll be safer on your cot.”

The shelling stopped as suddenly as it had started. Later Barry learned that a pair of motor torpedo boats had routed the Jap cruiser, with two gaping holes below her waterline.

The damage to ships on the flying field was comparatively light. One bomber had received a direct hit. Three more were damaged by shell fragments. Sweet Rosy O’Grady had escaped without a scratch. The worst tragedy was the killing of a twin-engined bomber’s crew when a shell exploded in their tent. Seven men had been sleeping there. All that was found of them was buried the next day in a single grave.

The attack was the last thing needed to make Barry and his friends ready for a raid of their own. Every man in the field was fighting mad. When O’Grady brought them the news that they were scheduled for a bombing mission that day, the Rosy’s crew cheered like maniacs.

“We’re going with the squadron to lay eggs on Rabaul,” the Old Man told them. “High-altitude stuff. You gunners will probably get your chance at a few Zero fighters, so make sure you load up with ammunition before we leave. Here come the carts to bomb us up now.”
