The above trenches were to be consolidated at once and barricades for Grenade Stations erected at about points A, B, C, D, E, F and G, as shown in corresponding red letters on the sketch. In the case of E, F and G, communication was to be at once opened to our Grenade Stations at Nos. 4, 3 and 2. If the whole of G11A was secured, a barricade was to be erected about point D1 in place of D and an emergency one afterwards at D.

In addition to the Battalion the following troops were to be at the C.O.'s disposal. Two grenade teams from the 7th H.L.I. and as a reserve two companies and three grenade teams from the 7th H.L.I., two grenade teams from the 6th H.L.I. and two from the 5th A. & S.H. In order to prevent confusion the grenade teams were lettered to correspond with their allotted stations and each grenadier wore on his arm a red band marked with the letter of his station, the reserves being distinguished by prefixing the figure 2.

Special arrangements were made by Brigade signalling officers regarding signal communication, and throughout the entire attack and afterwards these arrangements worked admirably.

The attack was divided into two portions, that on G12 and the communication trench leading into it from Sap 2 being named the East Attack, that on G11A the West Attack.

The East Attack was carried out by "B" Company under command of Major Findlay, with the assistance of two grenade teams from the 7th H.L.I. The parties were specially detailed for certain objectives and shortly before 2 o'clock the attacking parties were all in position. At 2.15 p.m. a mine was exploded at point E, and immediately the grenade teams and assaulting parties were seen doubling forward to their objectives, followed at a brief interval by the consolidating parties. Immediately the positions were reached the erection of the barricade was proceeded with. All parties reached their objectives without casualties, but very shortly afterwards the enemy opened heavy shell-fire and some rifle-fire. A number of casualties soon resulted. The consolidating parties had a very stiff job to face, as these trenches had been continually bombarded for some months, with the result that there was a large amount of broken earth to be cleared away before reaching hard undersoil. It was almost like working in sand. The work was continued with great perseverance and after some hours our labours began to show satisfactory results. About 9 o'clock the enemy launched a counter attack against F and G barricades without success, and again at about midnight a second counter attack also failed. Our casualties, excluding those of the attached grenadiers, were two officers wounded, Lieut. M'Culloch and Lieut. Dewar. Other ranks, eleven killed and thirty-six wounded.

The West Attack was commanded by Major Neilson. G11A was known usually to be unoccupied by the enemy at least by day, but the main central communication trench running back from G11A to G12C was known to be held by the Turks at various points, and it appeared to be very much a question of time whether they or the attacking party could first reach the junction of this trench with G11A. The attack too was obviously handicapped in this race by the fact that it must be initiated from the mouth of a tunnel, entrance to which was difficult and from which it would be necessary to emerge into the nullah man by man. Time was bound to be lost in hastily assembling each party at the mouth of the tunnel and getting it started on its mission, while to rush men forward individually as they left the tunnel would inevitably result in confusion, disorganisation and possible disaster. Instructions were therefore that each party was to assemble in the nullah and move as quickly as possible on its objective as soon as it was complete.

"C" Company was employed in this attack with grenade teams from other companies of the battalion to make it up to the necessary number of parties, while each had a definite object as in the east attack. At 2.15 p.m., simultaneously with the mine which was exploded at point E, another mine was exploded in the cliff of Krithia nullah some yards north of the tunnel. A few minutes after this explosion one of the grenade parties, whose objective was the main central communication trench, had got clear of the tunnel, assembled and was moving up the slope outside the west parapet of G11A. It was closely followed by two other parties, all three being clear of the nullah five minutes after the exploding of the mine. These parties, which were moving along in front of G11A, came under heavy rifle-fire and had to drop into the trench. The overhead traverses, which were in a state of disrepair owing to the trench being unoccupied by the enemy, were low and made progress difficult and slow. Lieut. Aitken, who was leading the first grenade team, had rounded a bend in the trench with a bayonet man of his team when they came under fire from a few yards range from an erection at the junction of the main communication trench with G11A. The bayonet man was killed and Lieut. Aitken wounded in the arm and leg. By this time the enemy were beginning to throw grenades from their central communication trench and getting them into G11A. Lieut. Milne, Lieut. M'Dougall and many of the men were wounded. The parties were crowded, there being about forty of all ranks in twelve yards of trench; the assault party was entering the trench at its northern end and the tunnel was still full of the rear parties coming down. Communication with the attack commander was impossible, and Lieut. Leith, who was the only unwounded officer in the trench, decided to erect a barricade at the furthest point which had been reached. The barricade was completed by 3.30 p.m., and during its erection grenades were constantly thrown at the enemy communication trench but with little effect, as they had to be thrown uphill from the trench while the enemy's grenades frequently rolled down into it. In the meantime another grenade party under Lieut. Pitchford had entered the trench at its northern end; they found a party of the enemy behind a barricade of bags about twenty yards up the communication trench, which runs parallel to the nullah. On throwing a few grenades the enemy began to retire. The grenadiers, however, and Lieut. Pitchford advanced up the trench with a bayonet man, but on arriving at the barricade he found none of his grenadiers had been able to follow him as they had got entangled with the head of the assault party which was pushing up G11A. As he went back to fetch his grenadiers, the Turks reoccupied their barricade and opened a brisk rifle-fire; he then decided to erect his barricade at the junction of the trenches, and in spite of the enemy fire the work was carried out.
