First of all, the radioman was caught with all of his equipment. The hunchback cracked when faced with the grim prospect of facing a firing squad within a half-hour. His code book revealed a complicated mass of information which was deciphered at once, with some assistance from him. Exact locations were charted and objectives laid out. All of it was done on the run.

Before the officers were through with the radioman, a message was sent out to the Nazis holding up the attack until further instructions were given. The message was in code and properly sent so that it would be received by the enemy as an order from their key man in London. Herr Naggel’s secret code number was signed to it.

Then there was a cold and clearheaded gathering around the big map in the central control room. Four flights would go out. Not just four ordinary flights, but four all-out invasion formations with all the punch the Royal Air Force could put behind them.

Red Flight, with its three deadly Hawks, was assigned to go with the long-range Consolidateds over France to the base from which the biggest of the Jerry bombers would take off. This would be the first wave sent over, because it had the longest route. It would be protected by the Hawks and by Defiants equipped for long-range flying. At last Stan got away from the O.C. and dashed to the mess.

He had secured three capable gunners to take along because he expected an opportunity to do some ground strafing. The early morning sky was cloudy with high fog and black clouds. If the weather held all the way over, they would be able to stage a real surprise.

In the mess he found Judd and McCumber and Kelley talking with Allison and O’Malley. Other men were gathered in small groups. The tension was high in the room.

“When do we get the signal?” Judd asked. His detail was to a field in Belgium.

“Any minute now,” Stan said. He looked over Judd’s head and saw that O’Malley was munching a slab of apple pie.

“Sure, an’ we’ll all get to go on a long vacation after this is over,” O’Malley said. “There won’t be a Jerry left in the sky.”

Stan smiled but back of the smile there was a feeling of grimness. A lot of the eager youngsters gathered in that room would not come back.
