There is little to be said about the Sand Dunes, though, being on the flank, they were often the scene of operations. The sand here is soft and the going bad. Recourse in these operations was therefore had to camel transport. To the field engineer, difficulties were presented much as in the desert. During the trench warfare before Gaza, when a raid was carried out on Beach Post, no attempt was made to cut the enemy wire with our artillery, but the wire was simply pulled up by hand with the standards, for which the soft sand had provided no firm foundations. The Coastal Plain comprises, towards the north, the Biblical Plain of Sharon, and, towards the south, the land of Philistia. By this plain, and not through Judaea, lies the road from the Nile to the Euphrates. Along this plain have marched the invading armies of all the ages. Though generally a flat country, the flatness is relieved by a few rolling hills, of no great height. It is very fertile and has a good supply of water, contained in wells. It thus presents many advantages, and but few disadvantages, to an army operating in the field. Roads are good or are easily improvised, while such obstacles to an invader's advance do not exist here as in the hills. Our successes in the campaign under consideration were generally attained by first pushing forward along the plain and then turning right-handed into the hills. From the plain, the country rises, in places through the intermediate foot hills of the Shephelah, in places more abruptly and directly into the mountains of Judaea. These mountains are of limestone formation, terraced, where possible, for cultivation, and often wooded with olive trees or tilled as corn patches or vineyards. The scenery is rugged and pretty, the hill-sides generally steep, sometimes precipitous. This is the Palestine of the picture books. Deep gorges have been cut out by water action; but, as no rain falls throughout the summer months, these are, for the most part, but dry watercourses. There are a few good springs to be found in the valleys; the villagers upon the hills are, however, mainly dependent upon cisterns constructed in the rock, in which they catch as much water as possible during the winter rains. These mountains formed the stronghold of the Israelites, who never maintained sway for any length of time over the lower surrounding country. The mountains abound in ruins and are rich in caves, such as may have been the Caves of En-gedi and Adullam. One of the caves witnessed a lurid scene in our mountain fighting. A party of the enemy had established themselves in a cave with machine guns. Ghurkhas attacked, and the enemy, after inflicting casualties, thought to make good their escape by a back exit. But outside there were other Ghurkhas lying in wait, and, as the enemy emerged, they killed them all.
