On November 22, 1917, an action was fought on a larger scale than usual, in which British troops attacked and captured the Turkish post at Jabir, fifteen miles north of Aden, and its neighboring pickets. Losses were inflicted on the Turks and their defenses were destroyed.

On January 5, 1918, a strong reconnoissance was made toward Hatum and Jabir, the defenses of the former being destroyed by British troops. Aeroplanes cooperated with the British artillery, who inflicted considerable damage on the Turkish infantry.

In Mesopotamia there had been very little activity since the fall of Bagdad on March 11, 1917. Soon after that event a British column had been sent westward to Feluja on the Euphrates, a town almost on a line with Bagdad, but about thirty-five miles farther west. The Turks had offered no resistance and the town had been occupied by the British. The Turkish forces in the meantime had been withdrawn to Ramadie, about twenty-five miles northwest from Feluja and also on the Euphrates. In July 1917, a British column had successfully pushed forward about twelve miles in the direction of Ramadie, but after inflicting considerable losses on the Turks had to stop farther advance on account of the extreme heat.

Early in October, 1917, came the news that Ramadie had fallen on September 29, 1917. During the night of September 27, 1917, the British had moved in two columns from an advanced camp on the Euphrates, west of Feluja, one column on the right, the other on the left, and at dawn they attacked Mushaid Ridge, a low line of dunes running north and south from the Euphrates to Habbanie Canal.

At dawn they bombarded the main crest of the ridge, but the Turks had evacuated it, and they replied with a counterbombardment a few minutes afterward, expecting apparently that the British would follow up the barrage with an assault. The British, however, as soon as it became clear that the Turks were evacuating Mushaid Ridge, changed their line of attack. The right column was withdrawn and, swinging round west behind the left column, became the left wing of the force.

As soon as the infantry had carried Mushaid Ridge British cavalry made a wide sweeping movement across the desert round the right flank of the Turks. They left the battle area at 8 a. m. and by 4 p. m. they were established astride the Aleppo road on a regular line of hills running at right angles with the river five miles west of Ramadie.

By this move the Turks were cornered. The net which the British had flung round them was complete. They had no bridge behind them and were cut off from all hope of reenforcement or supplies. Their only chance was to drive in determined counterattacks, and to break through before the British drew the ring in closer and drove them out from their trenches with their artillery.

Meanwhile the British infantry were closing in. At 1 o'clock, after bombardment, one column attacked Ramadie Ridge, on the right, while the other was working round to Azizie Ridge, on the left. The capture and holding of Ramadie Ridge by British and Indian infantry was a difficult achievement. This low pebbly rise is perfectly smooth, a long and gentle gradient barely seventeen feet above the plain level. It offered no cover of any kind, and the British infantry became visible to the Turks a full 200 yards before they reached the top of the rise. As soon as they came into view the Turks opened concentrated rifle and machine-gun fire on the British front and right flank, while their guns opened intense enfilade fire from the batteries on the left. The British and Indian soldiers hung on to their positions and at night dug themselves in. Their action so occupied the Turks that the left column was able to work round and seize the Azizie Ridge before dusk with very little opposition.

At night British cavalry, who occupied strong points on a front of three miles along the ridge, prepared for a desperate struggle. The expected attack began the battle after 3 o'clock, when the Turks tried to break through between the cavalry and the river. The action continued for two hours till dawn, when it degenerated into casual sniping. The nearest Turkish dead were found within fifty yards of the cavalry trenches.

In the meantime the infantry soon after daybreak had taken up the attack again and in face of well-directed fire and against repeated counterattacks, had carried the last outlying defenses of the Turks on the British left, until 8 o'clock, September 29, 1917, they had seized and were holding the bridgehead of the Azizie Canal. After this new repulse an intense bombardment was opened on the Turkish trenches. The British line of cavalry, far away west, soon saw the dark masses of the enemy approaching and apparently prepared for bloody battle. They watched this advance, as they thought, for over an hour, but there came a moment when, to their astonishment, they saw the Turks turn and walk in mass formation toward the British. The Turkish guns were silent and white flags went up all along the line.
