The Anzac area now consisted roughly of two lines. Taking the sea as a base, the inner line resembled a V, starting from Hell Spit, running up Maclagan's Ridge, around to Plugge's Plateau, and then down the face of the cliff to Ari Burnu, the northern limit of Anzac Cove. This was the inner line of defence, and was never really manned, except by field guns and a howitzer or two. The outer line was shaped like a boomerang, with Quinn's Post as the apex. The fire trench started from a point about 1000 yards south of Hell Spit and ran up the crest of low ridges, thence to the hills overlooking Monash Gully to Steel's Post, Courtney's and Quinn's; next came Dead Man's Ridge and the post called Pope's Hill. Here the impassable ravine intervened, on the other side of which was the section later known as Russell's Top, whence the line took a right-angled bend down Walker's Ridge to the sea. There probably never existed a more tangled and confused line, consisting as it did of posts perched perilously on the brink of steep cliffs, often not even connected one to the other.

Malone, Post Commander; and Major Ferguson, R.E., Engineer Staff Officer for No. 3 Defence Section.] Quinn's Post. Of all these posts, Quinn's became the most famous. It was the salient of the Anzac line and the nearest point to the Turk. Looking back, it is a marvel that the place ever held at all. If the enemy could have shelled it, Quinn's would not have lasted five minutes. It was first held, a ragged trench line just below the crest, by men of the 4th Australian Infantry Brigade, which formed part of the N.Z. and A. Division. Those famous battalions--the 13th, 14th, 15th, and 16th Australian Infantry--established themselves on the night of April 25 at the head of the gully named after their well-known Brigadier. The Turk seemed determined to regain possession of Quinn's--this would have imperilled the whole Anzac line, for the holding of Quinn's alone ensured the communications by way of Shrapnel Valley and Monash Gully. Because holding Quinn's meant holding Anzac, no labour was too great to be expended on it. Men in the bomb factory, having completed a long day's work, turned to again when it was made known that "Quinn's was short of bombs," and pathetic it was to see these hard-swearing Australian and New Zealand sappers nodding their heads and dropping off to sleep with a detonator in one hand and a piece of fuse in the other, only to wake with a start and, in the small hours of the morning, carry the product of their toil up to their beloved Quinn's--a journey of over a mile in the dark with a box of high explosives!
