Von Rheinhoff's battered squadron rode raggedly to safety.

"Got him—whoop!" yelled a thousand voices, as from one machine there came a scatter of pieces as a high-explosive shell burst under the wing, and the soaring bird collapsed and came trembling, slowly, head-over-heels to the ground.

Von Rheinhoff, that redoubtable man, was half conscious when they pulled him out of the burnt and bloody wreck.

He looked round sleepily at the group about him and asked in the voice of a very tired man:

"Which—of—you—fellows—bombed—our Kaiser?"

Tam leant forward, his face blazing with excitement.

"Say that again, sir-r," he said.

Von Rheinhoff looked at him through half-opened eyes. "Tam—eh?" he whispered. "You—nearly put an empire—in mourning."
