It was my plan to keep them very high in the air, beyond what we estimated was the effective range of Talon’s black flash. They were armed only with small explosive bombs, but were expert at dropping them upon a mark.

A hundred and fifty of these mounted girls gathered now in a hovering group, then in wedge-shape, flew in a wide, slow circle. The birds were well-trained, capable of flying swiftly to great heights. And the most agile of the young girls; Sonya had selected them carefully.

This unit was the swiftest, most mobile of my forces. Sonya was to lead it. She was presently ready, bringing up her great gray bird, with its rug saddle upon which she would recline on its back between its great spreading wings.

She was dressed, as were all the girls in the air squadron, in a single dark flowing garment from shoulder to knee, with her hair bound tightly in braids around her head. The small metallic bombs were in a belt at her waist, bombs fitted with a chemical most explosive.

She offered her hand in my own fashion.

“Good-bye,” I said. “And remember, Sonya, keep well up, and listen to my signals. Do not attack until I order it.”

She leaped upon her mount. It rose over me with dangling legs; the rush of air from its wings was on my face. In a moment I saw her up there, taking her place just below the girl at the point of the wedge.

From the garden, the first of the flying platforms rose. There were three of this size, each with twenty men and some ten girls. Forty birds were harnessed to each platform: birds in tandem along each side, and two long strings in front. Four girls were to drive them; the other girls had bombs, and the men had the smaller range electronic needle-pipes.

These platforms were fairly swift. They were insulated underneath, with the shaggy black fabric of woven wire through which the insulating current circulated. And they had side shields which could be raised; and dangling, insulating curtains beneath some of the birds.

I stood watching the three platforms as they rose majestically, joined the mounted girls, and circled with them over the city.
