Those who wish to imagine the scenes must think of twenty miles of any rough and steep sea coast known to them, picturing it as roadless, waterless, much broken with gullies, covered with scrub, sandy, loose and difficult to walk on, and without more than two miles of accessible landing throughout its length. Let them picture this familiar twenty miles as dominated at intervals by three hills bigger than the hills about them, the north hill a peak, the centre a ridge or plateau, and the south hill a lump. Then let them imagine the hills entrenched, the landing mined, the beaches tangled with barbed wire, ranged by howitzers and swept by machine guns, and themselves three thousand miles from home, going out before dawn, with rifles, packs, and water bottles, to pass the mines under shell fire, cut through the wire under machine gun fire, clamber up the hills under the fire of all arms, by the glare of shell-bursts in the withering and crashing tumult of modern war, and then to dig themselves in in a waterless and burning hill while a more numerous enemy charge them with the bayonet. And let them imagine themselves enduring this night after night, day after day, without rest or solace, nor respite from the peril of death, seeing their friends killed, and their position imperilled, getting their food, their munitions, even their drink, from the jaws of death, and their breath from the taint of death, and their brief sleep upon the dust of death. Let them imagine themselves driven mad by heat and toil and thirst by day, shaken by frost at midnight, weakened by disease and broken by pestilence, yet rising on the word with a shout and going forward to die in exultation in a cause foredoomed and almost hopeless. Only then will they begin, even dimly, to understand what our seizing and holding of the landings meant. All down the southeastern coast of this Peninsula or outlier from Europe is a channel of sea, known, anciently, as the Hellespont, but in modern times more generally as the Dardanelles, from old fortifications of that name near the southwestern end of the Strait. This channel, two or three miles across at its southwestern end, broadens rapidly to four or five, then narrows to two, then, for a short reach, to one mile or less, after which (with one more contraction) it maintains a steady breadth of two or three miles till it opens into the great salt lake of the Sea of Marmora, and thence by another narrow reach into the Black Sea, or Euxine. It is a deep water channel, with from 25 to 50 fathoms of water in it throughout its length. The Gallipoli, or European, shore is steep-to, with a couple of fathoms of water close inshore, save in one or two beaches, where it shoals. On the Asian shore, where the ground is lower and the coast more shelving, the water is shallower. A swift current of from two to three knots an hour runs always down the channel from the Sea of Marmora; and this with a southwesterly gale against it makes a nasty sea.
