While we were quietly pursuing our road, with the Kél-owí in the van, the Tinýlkum marching in the rear, suddenly Mohammed the Sfaksi came running behind us, swinging his musket over his head, and crying lustily, “He awelád, awelád bú, ʿadúna já” (“Lads, lads, our enemy has come”), and spreading the utmost alarm through the whole of the caravan. Everybody seized his arms, whether musket, spear, sword, or bow; and whosoever was riding jumped down from his camel. Some time elapsed before it was possible, amid the noise and uproar, to learn the cause of the alarm. At length it transpired. A man named Mohammed, belonging to the caravan, having remained a little behind at the well, had observed three Tawárek mounted on mehára approaching at a rapid rate; and while he himself followed the caravan, he left his slave behind to see whether others were in the rear. The slave, after a while, overtook him with the news that several more camels had become visible in the distance; and then Mohammed and his slave hurried on to bring us the intelligence. Even Mr. Richardson, who, being rather hard of hearing, judged of our situation only from the alarm, descended from his slender little she- camel and cocked his pistols. A warlike spirit seemed to have taken possession of the whole caravan; and I am persuaded, that had we been attacked at this moment, all would have fought valiantly. But such is not the custom of freebooting parties: they will cling artfully to a caravan, and first introduce themselves in a tranquil and peaceable way, till they have succeeded in disturbing the little unity which exists in such a troop, composed as it is of the most different elements; they then gradually throw off the mask, and in general attain their object. When at length a little tranquillity had been restored, and plenty of powder and shot had been distributed among those armed with firelocks, the opinion began to prevail, that, even if the whole of the report should be true, it was not probable that we should be attacked by daylight. We therefore continued our march with a greater feeling of security, while a body of archers was despatched to learn the news of a small caravan which was coming from Sudán, and marching at some distance from us, behind a low ridge of rocks. They were a few Tébu, with ten camels and between thirty and forty slaves, unconsciously going to meet a terrible fate; for we afterwards learned that the Imghád of the Hogár, or rather the Hadánara, disappointed at our having passed through their country without their getting anything from us, had attacked this little troop, murdering the Tébu, and carrying off their camels and slaves.
