Rob maintained his position in the front rank, but escaped all injury through the possession of the Garment of Repulsion.  But he took an active part in the fight and pressed the button of the electric tube again and again, tumbling the enemy into heaps on every side, even the horses and camels falling helplessly before the resistless current of electricity.
The Tatars shouted joyfully as they witnessed this marvelous feat and rushed forward to assist in the slaughter; but the boy motioned them all back.  He did not wish any more bloodshed than was necessary, and knew that the heaps of unconscious Turks around him would soon recover.
So he stood alone and faced the enemy, calmly knocking them over as fast as they came near.  Two of the Turks managed to creep up behind the boy, and one of them, who wielded an immense simitar with a two-edged blade as sharp as a razor, swung the weapon fiercely to cut off Rob's head.  But the repulsive force aroused in the Garment was so terrific that it sent the weapon flying backwards with redoubled swiftness, so that it caught the second Turk at the waist and cut him fairly in two.
Thereafter they all avoided coming near the boy, and in a surprisingly short time the Turkish forces were entirely conquered, all having been reduced to unconsciousness except a few cowards who had run away and hidden in the cellars or garrets of the houses.
The Tatars entered the city with shouts of triumph, and the chief was so delighted that he threw his arms around Rob's neck and embraced him warmly.
