No one had slept during the night. Re-embarkation was suggested, but a conference was held and the Generals decided to hold on. The men made strenuous efforts. Those not actually fighting were employed making roads up Maclagan's Ridge in the centre, and up Walker's Ridge on the left, in order that the guns might be man-handled up to the positions selected by the artillery commanders. [Illustration: [_Photo by the Author_ UNLOADING GUNS. The stern of the horse boats dropped in the water makes an inclined plane down which the gun is manhandled. The country was too rough for horses, but fifty men on a rope can overcome most obstacles.] About midnight, three companies of the 15th Battalion, 4th Australian Infantry Brigade, arrived and were sent up to reinforce the 1st Australian Division away on the right. They had been hardly pressed just before sunset, and orders were given that all available troops were to support the covering force (the 3rd Australian Infantry Brigade) as they arrived, and to connect up with the New Zealand Infantry Brigade on the left. During the remainder of the night, platoons and companies of the Wellington Battalion of the New Zealand Infantry Brigade, and of the 13th, 15th, and 16th Battalions of the 4th Australian Infantry Brigade, were brought ashore. The troops arrived in very irregular order--some from one ship and some from another. As each platoon or company came ashore, it was immediately despatched, under the senior officer present, to support the right flank, where the 1st Australian Division was most hotly engaged. The result was that units of both divisions became hopelessly mixed up, and it was several days before they could be disentangled. By 3 a.m., the whole of the Australian 13th Battalion had arrived. The bulk of it was held temporarily in reserve. One and a half more companies of the Wellington Battalion now occupied Plugge's Plateau, above the beach, and half a company had been sent off to join the 1st Australian Division on the right. By 5 a.m., the remaining company of the Wellington Battalion had arrived, and by 6 a.m., a section of the New Zealand Howitzer Battery was brought ashore, and gladdened the heart of every infantryman as it came into action at the foot of Howitzer Gully. "Boom!" went the howitzer. "The guns, thank God! the guns!" murmured the tired soldiers. Shrapnel Gully. The Turk quickly realized that the valley running from behind Hell Spit deep into the centre of Anzac must be the channel of communication. His gunners were so assiduous that it was quickly christened Shrapnel Gully. The top of this valley was afterwards known as Monash Gully.
