In anticipation of this advance, a party of selected officers and scouts lived day and night out on the Suvla Flats and in the Turkish territory on the Sari Bair. These were the men who were selected to guide the troops over the new ground to be attacked. Two other important works were put in hand at once in the Anzac area; the first, to widen the long communication trench from Anzac to the outposts; the second, to make a road available for wheeled traffic along the beach. In order not to make the enemy suspicious, this had to be done after dark, as the entire area was under the observation and rifle fire of the enemy on the heights. Making the Beach Road. Night after night the troops who were "resting" crept with their picks and shovels along the beach, to make the necessary road. This after-dark activity is most trying--each man working as silently as possible with his rifle at his elbow. Any noise is a magnet certain to attract machine-gun fire. Even in daylight it takes careful management to collect working parties and the necessary transport at the right spot, but in the darkness and in a region where enemy scouts and snipers roamed as soon as daylight failed, the difficulties were increased a hundredfold. Sand makes a poor road. To get a reasonable result it was necessary to collect the big stones of the seashore and carry them to the shore edge of the beach and place them as a foundation; on the top of this, clay was deposited--carted from the hillside near by in the mule carts of the Indian transport service; the whole was top-dressed by the sand of the beach, and finally, the hard-worked soldiers carried petrol tins of water from the sea and poured it over the surface to make the material set. So, harassed by the splutter of machine guns night after night, and weakened by the heat of the day, the faithful souls of the working parties steadily carried the road from Anzac Cove along North Beach towards the Suvla Flats.

To get troops quickly and secretly from Anzac to the outposts and to the foot of the deres up which the assaulting columns must approach the Turk, it was necessary to widen the communication trench known as the "Big Sap." This trench had been evolved as the outposts were established, and at many places could be enfiladed by the enemy on the heights; and nowhere was it wide enough to take troops two abreast. The pack mules used it by day, and though the soldier cared little for Turkish shells, he lived in fear of the donkey's steel-shod hoofs; it was no uncommon sight to see the soldier, disbelieving the warning "No kick! No kick!" of the Indian muleteer, climb out of the trench and risk a bullet rather than encounter a transport mule.
