"G.o.d pity San Francisco!" murmured the Commanding Officer, and stepped back involuntarily as the whole fleet lifted their glyco-scarzite crammed bellies from the field and, as if moved by some magical, unseen, unheard force, shot up into the darkness with ever gathering speed.

"G.o.d pity it, indeed!" chuckled Singe exultantly. "It'll need it!"

The C. O. sighed and shook his head slowly. "War!" he mused. "And yet, it's our only chance." For a moment he paused, seemingly unconscious of the macabre little form next to him, still gazing aloft at the now invisible torpedoes, and then muttered:

"And G.o.d pity Basil Hay, who's giving his life to America--a glorious, unselfish hero. G.o.d pity Basil Hay!"

American flyers never knew of Basil Hay's last fight. Had they, it would have become legendary.

For Hay fought a grim battle against two foes. One, he could face and conquer, as he had conquered often before. But the other lurked next to his dauntless heart, and it Hay could not subdue.

It was death.

Truly, Hay's fight there in the wet clouds above Sola Ranch was an inspired one. He fought almost by instinct alone, instinct twenty years of piloting had planted deep in his veins. He fought for Lance--for America. His eyes, glazing rapidly, could not distinguish the roaring phantoms that laced around his lone plane, but uncannily his bursts of fire went home again and again, while theirs ripped aimlessly over the Goshawk's h.e.l.l-driven snout.

Of course it could not last. Gallant spirit alone kept Basil Hay taut at his controls. Spirit alone thrust back the ever-increasing surge of black oblivion that pounded at his heart and brain. Spirit alone sent the pitifully outnumbered plane corks.c.r.e.w.i.n.g in peerless maneuverings that baffled the on-pa.s.sing Slavs and thrust four of them to the sodden ground in flame. Spirit that would not surrender--but had to.

They could never have conquered Basil Hay in a plane. An ambushing bullet that caught him off guard did that. And finally Hay fell.

But he had kept them for ten full minutes. Ten minutes--each one a lasting, mute testimony to his unquenchable, unyielding spirit.

He flung a last salvo from his hot machine-guns, then, heart numbing, jerked back the control-stick and careened high. He slumped down. The plane paused, wallowed crazily for a moment, and then roared earthward, "Carry on!" formed faintly on its dead pilot's b.l.o.o.d.y lips.

Basil Hay had fought his last fight.

Ten minutes....

Lance hadn't expected that long. He'd thought Hay would die in a few seconds. The man was mortally wounded; could not last.

Nevertheless, minutes or seconds, he was entrusted with the Singe beacon, and it was his job and his will to put it through.

He'd climbed the Slav plane up to its ceiling, driven it till it simply refused to go higher, and then roared on towards San Francisco.

Each second he expected to see others come hurtling after him. When they did not, he knew how really great Hay's will was. It was an inspiring example.

But his brain was tortured by a mult.i.tude of conflicting doubts. A patrol of Slav scouts had ambushed them. Just how much did the Slavs know, then, about the torpedoes?

He, Lance, had to guide the Singe beacon. Quickly he reviewed what Hay had told him.

"Light about five miles this side of Frisco. Anywhere in that territory would do, though. The beacon doesn't go up in a narrow ray; it spreads, diffuses."

_Spreads, diffuses._

Hay had been clad in Slav uniform, and thus could, with a certain measure of safety, put the beacon machinery on the ground itself. But Lance was in American uniform; if he landed, he ran great risk of being noticed and attacked at once.

Lance saw immediately that there was only one way out. It was sure death, but Hay had expected death, and so must he.

His lips set in stern resolve. It meant good-by--farewell to the girl he'd left behind, farewell to life, farewell to everything--but not for a second did he debate the course he would take.

Lance glanced at his watch. Nine-thirty. The torpedoes were even now on their way, hurtling along miles above the earth. In fifteen minutes they would be over San Francisco. In fifteen minutes the Singe beacon had to meet them.

He was not familiar with the Slav plane's instruments, but he judged he'd traveled some hundred and twenty-five miles; was nearing the outskirts of San Francisco. The air below would be thick, probably, with enemy scouts, but his appearance should pa.s.s unchallenged as long as they didn't glimpse his betraying uniform.

He set the plane's nose down in a long slanting dive.

Whipping through the clouds, the guarding search-rays of San Francisco were soon visible. Lance saw a few patrols of enemy scouts; he clung to the clouds, decreased his speed, and began circling over the heart of the metropolis itself.

Twenty to ten.

Occasionally a Slav plane flashed by him. Thank G.o.d, they didn't challenge! Lance went still lower. Finally, at a thousand feet, he set the helicopter props in motion and hung in mid-air--directly above the very center of the city.

Sixteen minutes to ten.

Now!

In the American front-line trenches, ma.s.sed troops crouched expectantly. Cl.u.s.tered on every air base were flights of planes, each one crammed with bombs. Far behind, the Yank gun-crews edged nervously up to their mighty charges, and fingered anxiously the stubby gas sh.e.l.ls which soon would be flung through the dripping night.

And at Base No. 5 a very uneasy Colonel Douglas paced back and forth in his office, muttering: "No news from Lance! No news from Lance!

G.o.d! He can't have failed! But why doesn't he show up?"

He had not failed.

Hovering in the plane over San Francisco Lance squirmed round in his seat, reached back into the fuselage, and pressed rapidly the studs on the Singe beacon. A high whining noise pierced instantly through the plane. And up stabbed the beacon, invisible, deadly--up, up, up to a thin realm miles above, where it flashed into an awesome squadron of terrible sh.e.l.ls of steel!

Sh.e.l.ls that, a second later, wavered, staggered, and plunged earthward!

And Lance tensed in his seat. From above, he caught a tiny whistling noise--a whistling that hurtled into a terrific shriek--that roared ever closer.

"Carry on!" he muttered. "Carry on!"

The words froze on his lips, for the world was suddenly consumed, it seemed, by flame and splitting, bellowing thunder.

The American guns spoke.

From every aerodrome long flights of scouts and bombers and transport planes roared upward.

In the front trenches the troops, still somewhat dazed by the earth-shaking explosion that had just tumbled from the far horizon--a horizon still lit by leaping tongues of awful flame--poured over the top, gas-masks on, repeaters and portable machine-guns at the ready, with a fierce cry on their lips.

Before that avenging attack the Slavs, their very spine broken, bewildered and confused, already turning in panic, could not stand.

America swept to the Pacific, and left death in her wake. And when she came to San Francisco, not even the sternest fighting men, still hot from battle, could repress a shudder, so awful was the devastation.
