"I can't be very particular about the company I keep," he thought, "and this gang hasn't tried to murder me, as the rascally Turks did. So for the present I'll stand in with the scowling chief and try to get a shot at the thieves who robbed me. If our side wins I may get a chance to recover some of my property. It's a slim chance, of course, but it's the only hope I have left."
That very evening an opportunity occurred for Rob to win glory in the eyes of his new friends. Just before sundown the gates of the city flew open and a swarm of Turks, mounted upon fleet horses and camels, issued forth and fell upon their enemies. The Tatars, who did not expect the sally, were scarcely able to form an opposing rank when they found themselves engaged in a hand-to-hand conflict, fighting desperately for their lives. In such a battle, however, the Turks were at a disadvantage, for the active Tatars slipped beneath their horses and disabled them, bringing both the animals and their riders to the earth.
At the first onslaught Rob shot his pistol at a Turk and wounded him so severely that he fell from his horse. Instantly the boy seized the bridle and sprang upon the steed's back, and the next moment he had dashed into the thickest part of the fray. Bullets and blows rained upon him from all sides, but the Garment of Repulsion saved him from a single scratch.
When his pistols had been discharged he caught up the broken handle of a spear, and used it as a club, galloping into the ranks of the Turks and belaboring them as hard as he could. The Tatars cheered and followed him, and the Turks were so amazed at his miraculous escape from their bullets that they became terrified, thinking he bore a charmed life and was protected by unseen powers.
This terror helped turn the tide of battle, and before long the enemy was pressed back to the walls and retreated through the gates, which were hastily fastened behind them.
In order to prevent a repetition of this sally the Tatars at once invested the gates, so that if the Turks should open them they were as likely to let their foes in as to oppose them.
While the tents were being moved up Rob had an opportunity to search the battlefield for the bodies of the three Turks who had robbed him, but they were not among the fallen.
"Those fellows were too cowardly to take part in a fair fight," declared the boy; but he was much disappointed, nevertheless, as he felt very helpless without the electric tube or the traveling machine.
The Tatar chief now called Rob to his tent and presented him with a beautiful ring set with a glowing pigeon's-blood ruby, in acknowledgment of his services. This gift made the boy feel very proud, and he said to the chief:
"You're all right, old man, even if you do look like a pirate. If you can manage to capture that city, so I can get my electrical devices back, I'll consider you a trump as long as I live."
The chief thought this speech was intended to express Rob's gratitude, so he bowed solemnly in return.
During the night that followed upon the first engagement of the Turks and Tatars, the boy lay awake trying to devise some plan to capture the city. The walls seemed too high and thick to be either scaled or broken by the Tatars, who had no artillery whatever; and within the walls lay all the fertile part of the oasis, giving the besieged a good supply of water and provisions, while the besiegers were obliged to subsist on what water and food they had brought with them.
Just before dawn Rob left his tent and went out to look at the great wall. The stars gave plenty of light, but the boy was worried to find that, according to Eastern custom, no sentries or guards whatever had been posted and all the Tatars were slumbering soundly.
The city was likewise wrapped in profound silence, but just as Rob was turning away he saw a head project stealthily over the edge of the wall before him, and recognized in the features one of the Turks who had robbed him.
Finding no one awake except the boy the fellow sat upon the edge of the wall, with his feet dangling downward, and grinned wickedly at his former victim.
