Our own casualties amounted to forty-seven men in the ground forces, eighteen of whom had been slain in hand-to-hand fighting with the few of the enemy who managed to reach our lines, and sixty-two in the crew and "kite tail" force of swooper No. 4, which had been located by one of the enemy's ultroscopes and brought down with long-gun fire.
Since nearly every member of the Sinsing Gang had, so far as we knew, been killed, we considered the raid a great success.
It had, however, a far greater significance than this. To all of us who took part in the expedition, the effectiveness of our barrage tactics definitely established a confidence in our ability to overcome the Hans.
As I pointed out to Wilma:
"It has been my belief all along, dear, that the American explosive rocket is a far more efficient weapon than the disray of the Hans, once we can train all our gangs to use it systematically and in co-ordinated fashion. As a weapon in the hands of a single individual, shooting at a mark in direct line of vision, the rocket-gun is inferior in destructive power to the disray, except as its range may be a little greater. The trouble is that to date it has been used only as we used our rifles and shotguns in the 20th Century. The possibilities of its use as artillery, in laying barrages that advance along the ground, or climb into the air, are tremendous.
"The disray inevitably reveals its source of emanation. The rocket gun does not. The disray can reach its target only in a straight line. The rocket may be made to travel in an arc, over intervening obstacles, to an unseen target.
"Nor must we forget that our ultronists now are promising us a perfect shield against the disray in inertron."
"I tremble though, Tony dear, when I think of the horrors that are ahead of us. The Hans are clever. They will develop defenses against our new tactics. And they are sure to mass against us not only the full force of their power in America, but the united forces of the World Empire."
"Nevertheless," I prophesied, "the Finger of Doom points squarely at them today, and unless you and I are killed in the struggle, we shall live to see America blast the Mongolian Blight from the face of the Earth."
