Before, however, the Russians undertook their own expedition, they were urgent in pressing on France and Great Britain the desirability of opening up the Dardanelles so as to bring the Allies into touch with each other through the Black Sea ports. In response to this invitation, the naval possibilities of which were insufficiently considered by the advisers of the British Admiralty, and the prospects of which had been roundly condemned by all who had previously considered the problem, Admiral Carden began a bombardment of the Dardanelles forts with old battleships, British and French, on 19th Feb., 1915. The bombardment was renewed on 25th Feb. and 6th March. Admiral Carden resigned on 16th March owing to ill-health, and was succeeded by Admiral de Robeck, who favoured the idea of breaking into the Sea of Marmora by rushing the straits. Four big ships, one the Queen Elizabeth, engaged the guardian forts, Chanak and Kalid Bahr, at long range (18th March); other ships closed in, and a French squadron penetrated as far as Kephez Point. But the hidden batteries, the mines, and various other devices frustrated the attempt, which was a practical failure by the afternoon. Two good ships, Irresistible and Inflexible, were put out of action, and two others, Bouvet and Ocean, sunk. After this Admiral de Robeck accepted the professional view that a fleet operation should be combined with one on land. Lord Kitchener, who had been as little disposed towards the Dardanelles adventure as Lord Fisher, reluctantly consented, and General Sir Ian Hamilton was appointed to command the British expedition, while General d'Amade was in charge of the less numerous French Colonial Corps.
Sir Ian Hamilton's force eventually comprised the 29th Division, the Australian and New Zealand (Anzac) Corps, the East Lancashire Territorial Division, and part of the Royal Naval Division. There was an unfortunate delay in getting the expedition off from its Egyptian base, and the Turks had ample time to prepare for its landing (25th April), which they did not believe to be a possible feat. The landing was effected, nevertheless, with incomparable gallantry, at five beaches on the nose of the Gallipoli Peninsula, and at Gaba Tepe (by the Anzac Corps) farther north. Some 8000 men were got ashore in twelve hours, and an advance was made on the following day (26th April). On 28th April the French Corps, which had made a feint attack on the other side of the Narrows, was brought across to assist in a general advance on the dominating height of Achi Baba. The resulting engagement, the battle of Krithia, revealed the fact that the Turkish field fortifications, the Turkish artillery, and the Turkish numbers had all been too well organized under von Sanders to admit of being rushed. Evidence accumulated that Achi Baba, which was the key to the Dardanelles forts, could only be taken at ruinous cost by a frontal attack, though an attack in force on 6th May went nearer to success than any other, and appeared to fail only through a culminating misfortune of misdirected artillery. Fighting continued in May and June, both here and at Gaba Tepe, where General Birdwood commanded the Anzac Corps. Engagements in which local advances were made took place on 29th May (Anzac Corps), 4th and 21st June (French Corps), 28th June (29th Division), and though the climate and the insufficient protection inflicted appalling losses on the hard-tried British and French troops, it was on the Gallipoli Peninsula that the flower of the Turkish army also was lost. Of the naval forces the Queen Elizabeth was summarily ordered home just before a new Turco-German submarine campaign set in; three more old battleships were torpedoed; but the English submarines retaliated by torpedoing a Turkish battleship, gunboats, and transports in the Straits.
General Gouraud relieved General d'Amade in the middle of May, but was badly wounded by a shell (30th June), and returned to France. General Sir Ian Hamilton, who had unceasingly asked for more guns and more men, received some part of the aid he asked in order to put a new plan into operation. The plan was to land a force at Sari Bair, on the neck of the Peninsula, where it could co-operate with the Anzac Corps in forcing a way to the commanding heights there, and ultimately might take the Turks in the flank. One force was to land at Anzac Cove; two other of the three new divisions sent out to
Sir Ian Hamilton were to be landed 4 miles north, at Suvla Bay. The forces at Anzac were landed on 4th-6th Aug., bringing up the numbers of Sir W. Birdwood's command to 36,000. Sir F. Stopford was in command of the force to land at Suvla Bay (6th and 7th Aug.), with Generals Hammersley and Mahon as divisional generals.
The fresh attack on the night of 6th Aug. was not completely successful, and the Anzac columns under General Godley were still short of the ridges at Koja and Chunuk on the night of 7th Aug. The Turks were then alive to the threat, and made continuous counter-attacks, so that by 10th Aug. all the efforts of the combined force of Anzacs, Gurkhas, and English regiments had failed to maintain more than a slippery hold on the ridges. The chief cause of the failure was that the contributory aid of the attack at Suvla Bay farther north had not been forthcoming, owing to various reasons. Lack of water had exhausted the unseasoned divisions landed in Suvla Bay; misunderstandings among the generals were other reasons; and when the Commander-in-Chief, on hearing of their failure, came up from Zimbros, he met a situation which it was too late to redeem. General Stopford was succeeded by General de Lisle (15th Aug.). Lord Kitchener declined to send further troops from home, and though Sir Ian Hamilton, bringing the veteran 29th Division up to Suvla, with reinforcements of yeomanry, made another attempt on 21st Aug., it was unavailing. After 24th Aug. the British campaign assumed
a defensive character, and in spite of Sir Ian Hamilton's representations the War Office declined to waste further men and material on it. On 15th Oct. Sir Ian Hamilton was recalled, and Sir Charles Munro, who reported that the expedition should be abandoned, was supported by Lord Kitchener after personal inspection of the surroundings. The evacuation was carried out with remarkable success on 18th Dec. and 8th Jan. (1916). The cost of the expedition in men was 31,389 killed, 78,749 wounded, and 9708 missing.
Mesopotamian Campaign
The Mesopotamian campaign ran contemporaneously in part with the Dardanelles operations, and in part with the campaign between Erzerum and the Caucasus in Armenia, in which Russia co-operated. A small British force, sent out to the Persian Gulf in 1914, occupied Basra (22nd Nov.) and pushed outposts forward to the junction of the Tigris and Euphrates. General Sir John Nixon took command (Jan., 1915), and in April (11th to 14th), following a Turkish attack, the British force, now a division strong, advanced to Shaiba, and on 31st May took Kurna. Amara, on the Tigris, capitulated to General Townshend (3rd June), who was empowered to push forward an advance column, while another column, under General Gorringe, beat the Turks at Nasiriyeh (24th July). At this time the Russians were on the headwaters of the Euphrates.
