Two days later the camp broke up, and, with a naval flotilla steaming beside them up the river, they marched on Basra, which town they occupied, after meeting with only small resistance. They were now approaching the confluence of the Rivers Tigris and Euphrates, and were, indeed, within striking distance of that portion of the desert which, in days long gone by, was known as the Garden of Eden, where the toil of the inhabitants then living in those parts had converted what may have been a desert in their earlier days into a smiling garden the fame of which has descended through the ages. Yet now it was a desert, a sandy, gravelly stretch of dried-up, waterless, and inhospitable desert, peopled but sparsely, and for the most part only along the actual banks of the river, where the moisture, finding its way into the soil on either side, kept it fertile, and where grew a thick belt of palms, descending past Basra to the open sea. There were marshes, too, for the River Euphrates in particular, which traverses a flat country, has changed its course through the ages on numerous occasions. Some particular course may remain open for a considerable period, and have the appearance of being the main channel, yet always there are overflows, and often enough such a main channel is silted up with the dirt and debris coming from higher parts of the desert; then the water, bursting over the low banks, and particularly the southern bank, has gouged some other channel for itself, or has widened out into broad stretches of marsh--perhaps only two feet in depth--leaving no semblance of the river channel. "It's there, amongst the marshes, that the Turks lie hidden," the chief told Geoff that evening. "Of their numbers and of their exact positions I know nothing, yet the rumour has reached me that they are there, and that soon they will attempt to come in behind the British and attack them. It were well, my master, if some of those ships that I see floating upon the water, and in particular some of the smaller ones, were sent into the marshes. There are channels deep enough to take them, and if careful search were made it may be that the Turkish enemy would be discovered."
