Part 15

On the Western front it had been expected that the heavy hammering to which the Germans had been subjected during the battle of the Somme would be carried on in concert under the direction of Sir Douglas Haig and General Foch. But a change was made in the French High Command, General Joffre retiring, and his place being taken by General Nivelle, who had done so well at Verdun, while Foch was relegated to the task of preparing against a possible thrust of the Germans through Switzerland. Unity of command was not achieved, except in appearance. Nivelle's plan was to strike at the German centre; Haig was to aid him by simultaneous attack, though Haig's own prepossessions were in favour of freeing the Channel ports by a burst from the Ypres salient. In the result, neither plan succeeded. Nivelle failed because neither the French Government nor a section of the French soldiery would bear a repetition of the losses incurred in his thrust at the Chemin-des-Dames; Haig failed because he had neither the time nor the weather in which to drive his last blows home in the autumn of the year.

A contributory cause of the comparative failure of the Franco-British plan of campaign in 1917 was the want of perception of the intention of the Germans to withdraw from the positions in the Somme area which they had defended so stubbornly in 1916, and which the Allies were preparing to render untenable or to batter down. The want of perception was not complete, but both British and French plans were upset by the suddenness and extent of the withdrawal, which the Germans effected with much less loss than they should have been forced to sustain. The first symptom of the general withdrawal was discovered in March, when portions of St. Pierre Vaast Wood, near the junction of the French and British lines, were found to be evacuated. By 17th March the German voluntary retirement was in full swing, and their forces ruined everything as they retreated. By 17th March, also, the British front from Roye to Arras was moving forward, and on 2nd April the Fifth Army was within two miles of St. Quentin, while the Fourth Army on 5th and 6th April was at Ronssoy and Lempire. While the British armies were pushing towards the Cambrai-St. Quentin line the French were pushing on a 30-mile front from the north of the Upper Somme, towards the new German line from St. Quentin, behind Soissons, in front of the St. Gobain plateau, the Forest of Coucy, and the Chemin-des-Dames. Behind the new line Nivelle matured reconstructed plans for the great French attack towards Laon.

Of the new fortress line (the Hindenburg and Drocourt-Queant line) which the Germans had constructed and continued to improve, the La Fere-Laon position and the Chemin-des-Dames were the southern bastion, and the Vimy Ridge the north-western pillar. Sir Douglas Haig's preconcerted plan had been to attack the Arras front, not in order to assault this line, but as preliminary to the Ypres salient thrust farther north. Nevertheless, the plan could be adapted and it was prosecuted. Preparations on a large scale, equivalent to building a counter-fortress front, had been made for the Arras operations, and the greatest precautions were taken to lend the attack all the support which mines and artillery could give. Two armies, the First (General Horne) and Third (General Allenby), were prepared for this action. Horne's army made its attack on the Vimy Ridge, with the Canadian Corps as shock troops, on 9th April, and the attack was extended on a 12-mile front from Henin-sur-Cojeul, south-east of Arras, to Givenchy-en-Gohelle, north of Arras. The Canadians took the whole of Vimy Ridge, except its northern end, the conquest of which was completed next day. Five villages fell into British hands and 6000 prisoners. Subsequent days saw the extension of the victory, but though Vimy village, Givenchy-en-Gohelle, and other important points were taken, the fortified villages of Heninel and Wancourt held out by dint of machine-guns, and prevented the possibility of the Third Army's joining hands with the Fifth Army beyond the third line of the German defences until it was too late. The whole of the expected gains were therefore not realized, but the possession of the Vimy Ridge was invaluable, and became a most important factor in stemming Ludendorff's rush in 1918, when he attacked the Third Army after destroying the Fifth.

The British attacks did not end on 11th April, as they should have done, but were continued here, as well as at other portions of the British line to its junction with the French armies, in order to lend assistance to Nivelle while his attack in Champagne was in progress. It was a very costly procedure, and its scope may be inferred from the statement that on 23rd April a "second phase of the battle of Arras" began; another 12-mile front east of Arras was launched on 3rd May; and there were bloody encounters about Bullecourt or Fontaine-les-Croiselles on 7th and 12th, 15th and 16th, and 21st May. Some 20,000 German prisoners were captured in these preliminary spring operations, but the drainage in casualties to the British armies was heavy, and more damaging still was the loss of time by the postponement of Field-Marshal Haig's major plan farther north.

This, however, was at last begun on 7th June by the assault on the Messines-Wytschaete Ridge, which, under the name of the 'Battle of Messines' denotes one of the most completely successful actions fought in that year. It was undertaken by the Second Army (General Plumer), and the preparation for it, including the mining of the ridge, had been as near perfection as possible. The attack was launched; the mines which blew the German front line to pieces were exploded on the morning of 7th June at ten minutes past three. Nine miles of front were stormed and 6400 prisoners taken. In the next week the number of prisoners was considerably augmented; German counter-attacks were beaten off; and the captured position enlarged and firmly consolidated.

From this time forward the operations of the British armies may be envisaged as an attempt to enlarge the great bulge of the Ypres salient by fighting their way up to and along the ridges which enclosed it, so as to force the Germans to relinquish their hold on the coast near Nieuport, Zeebrugge, and Ostend. One very awkward spoke was put in the British wheel by an attack (10th July) on the extreme coastal sector of Lombaertzyde and the mouth of the Yser, by which any combined sea and land attack that might have been projected by the British was discounted. Most of the positions were recovered, but the amphibious plan had perforce to be postponed.

The putting into effect of Sir Douglas Haig's major plan, after the preliminary step of the capture of the Messines Ridge had been taken, did not operate till 31st July, when the 'Third Battle of Ypres' began, with a combined British and French attack on a 15-mile front beyond Boesinghe, on the Yser-Ypres Canal, to Zillebeke. The attack was conducted by the First French Army (General Anthoine); the bulk of the fighting fell on the Fifth British Army (General Gough). Twelve villages were taken and 5000 prisoners. There was, and could be, no break-through. The Germans rallied to a counter-attack, and were able to do so because their defences, their concrete pill-boxes, and their machine-gun effectiveness could, and did, hold up attacks before they progressed too far.

The rest of the British campaign in 1917 till it was arrested by the torrential rains of a wet October, and by the mud of the impossible declivities, may be summed up as a series of desperate forward thrusts which exacted each its toll of prisoners, ground, and positions, but none of which succeeded in its object of inflicting a lethal injury on the German resistance. In the end these attacks had to cease while the last fragment of coveted ridge, the Passchendaele spur, was still not won, because on that ridge, as elsewhere, though blood had been poured out like water, and losses endured with unflinching fortitude, flesh and blood could do no more. The chief actions were as follows:

15th Aug.--British attack on wide front from north-west of Lens to Bois Hugo, north-east of Loos. Enemy's position penetrated to 1 mile depth.

16th Aug.--Franco-British attack on 9-mile front north of Ypres-Menin road. British carry Langemarck.

15th to 21st Sept.--Second phase of third battle of Ypres. 3000 Germans captured.

4th Oct.--British advance on 8-mile front, anticipating German attack east of Ypres. 3000 German prisoners.

9th Oct.--Third phase of third battle of Ypres. One mile advance on Passchendaele Ridge. 2000 prisoners.

6th Nov.--British attack on Ypres Ridges. Canadians capture Passchendaele.

These attacks were interspersed with costly minor encounters, and by the repulse or endurance of counter-attacks. The battle may be said to have closed by stress of weather in mid-November.

It was followed on 20th Nov. by a British attack of an altogether different kind, in an unexpected quarter--at Cambrai. Here the Third Army, under General Byng, made an attack on a 10-mile front between St. Quentin and the River Scarpe--tanks being employed for the first time in large numbers to lead the advance without a preliminary bombardment. It was a complete surprise, and all but a complete success. The 'Hindenburg Line' was broken, numerous villages and 8000 prisoners were taken. If the cavalry had been up, as they ought to have been, a first-class disaster might have been inflicted on the Germans, and their railway communications at this point broken. But the cavalry were late; the next few days were spent in consolidation by peculiarly hard fighting; and on 30th Nov. the Germans counter-attacked and subjected the British defences of the newly-created salient at Bourlon Wood and Moeuvres to almost as severe a surprise as they had sustained ten days before. The British lost a number of prisoners, and had eventually to evacuate most of their hard-won positions.

_French Front in the West, 1917_

The history of the French armies in 1917 is largely the history of Nivelle's frustrated attempt to pierce the German centre between Soissons and Rheims in April; the pause necessitated by the fact that it was felt impossible to press the French armies too hard or too soon after the disappointment of the attenuated success at the Chemin-des-Dames, where the chief sacrifices of the attack took place; and the efforts on a more moderate scale by General Petain, who succeeded Nivelle, to win tactical victories at a moderate cost on the terrain acquired in the April adventure. The second battle of the Aisne, as Nivelle's offensive was called, was planned over a length of 50 miles from La Fere, on the Oise, round the edges of the Forest of Gobain and Coucy, to Laffaux, thence below the line of the Chemin-des-Dames ridge and behind the Aisne to the crossing of the river at Berry-au-Bac, and Brimont, near Nogent-l'Abbesse, to the Moronvilliers heights on the other side of Rheims.

The attack on the larger part of this line began on 16th April; that on the Moronvilliers sector on 17th April. The attack on the 16th was extremely costly; it succeeded in only part of its objectives, but it captured 11,000 prisoners. The next day, one of pouring rain, improved on the positions won, especially at the western end of the Chemin-des-Dames, and on the 18th and 19th Nivelle so far enlarged his successes as almost to give them the appearance of a great victory. But the French bolt had been shot, and, to put it plainly, Nivelle was not encouraged to go on. By the 28th he had taken 28,000 prisoners, 175 guns, and some of the strongest points on the heights of the Aisne; but everywhere the positions had been only half-won, and the temper of the French army as a whole had suffered too severe a test. Nivelle was succeeded by Petain and his plan was abandoned. The rest of the year was occupied by General Petain in very skilled attempts, named limited offensives, to repel the Germans from disputing some of the positions won and to enlarge the French gains at other points. The chief engagements were as follows:

5th May.--The French, co-operating with the British on a 20-mile front north of the Aisne, take Craonne and 6000 prisoners.

20th Aug.--French carry enemy defences north of Verdun on 11-mile front; 6000 prisoners. By 28th Aug. the French were back at their original Verdun positions.

23rd Oct.--French advance on the Aisne north-east of Soissons on e-mile front; 8000 prisoners. By 25th Oct. further 3000 prisoners and 160 guns were taken.

_The Balkans, 1917_

In the Balkans the military situation during 1917 remained much as the end of 1916 had left it, the Germans, as already mentioned, completing their conquest of Roumania, and the Allies remaining comparatively inactive in the field while they cleared up the extremely unsatisfactory situation in Greece. The chief operations consisted of a Franco-Serbian attack north of Monastir, and attacks by General Milne on the British front in the Struma valley; but though the situation remained in the field virtually unchanged, the political situation was vitally affected in 1917 by the deposition of King Constantine in favour of his second son, Alexander--the king being induced to abdicate on 12th June--and the formation of a new Government under M. Venizelos. From 30th June, Greece, having formally severed diplomatic relations with Germany, was at length added to the list of countries fighting on the Allies' side.

_Italian Campaign, 1917_

Italy, who, meantime, had proclaimed Albania an independent state under Italian protection, and occupied Yanina in June, 1917, had committed herself wholly to the Allies' cause in 1916 by declaring war on Germany on 28th Aug. It was in Aug., 1917 that Ludendorff began his preparations for the terrific blow which was to lead to the Italian disaster at Caporetto in October. During the earlier months of the year the initiative had remained with the Italians, and Cadorna had used it in a series of offensives which, while carrying him farther across the Carso towards Trieste, and winning seemingly impregnable positions in the Trentino, together with upwards of 30,000 prisoners and 140 guns, were indecisive, and left his exhausted troops--reduced by some 150,000 casualties--ripe for the blow which Ludendorff had prepared for them. The Russian Revolution and the collapse of Roumania freed Austria-Hungary at the same time from any anxieties on her Galicia front, so that she could concentrate all her energies and the bulk of her armies against the Italians. When the enemy's great counter-stroke was delivered on 24th Oct., the control of the campaign was taken over by the German High Command. Ludendorff had been training picked troops in special tactics--to be developed at their full strength on the Western front in the following year--and von Below was transferred from the French front to take command. Following an intense bombardment, the Austro-German troops were launched against the Second Italian Army between Zaga and Auzza, in deep formations so closely packed that the way could not be lost amid the prevailing snow and rain. Taken by surprise, and seriously demoralized in parts by Bolshevist propaganda and enemy intrigue, the Second Italian Army, which had hitherto distinguished itself by its splendid courage, found the whole of its left wing giving way before the impact, thus opening a gap for the enemy 20 miles wide over the Julian and Carnic Passes. Having shattered both the first and second Italian lines at Caporetto and Vodil Vrh, the Germans and Austrians surged forward from the Tolmino bridge-head until the retreating Italians, becoming entangled with their own reserves, broke in disorder. Although the right wing of the Second Army held, and many heroic efforts were made by isolated units, General Cadorna decided that it was impossible to save the situation from irretrievable disaster except by a general retreat to the Piave line. This was ordered on 26th Oct., when the broken fragments of the Second Army, as well as the Italian Third Army, began the great retreat which will be remembered as one of the finest achievements in Italian military history. The territorial gains of over two years' fighting had already been lost, and the conquering invaders reached within 15 miles of Venice, but they never succeeded in making the disaster irremediable. General Cadorna's scathing Order of the Day denouncing the units of the Second Army which had let the enemy through, and the new sense of national unity inspired by the military crisis, did their work. By 8th Nov. the bulk of the Italian armies, now in orderly retreat, were across the Piave, and two days later were ready to turn on their pursuers. The danger was not yet over; the enemy succeeded in carrying several further heights dominating the Venetian plain between the Piave and the Brenta; but by 21st Nov., when a last German attack was made on the Monfenara Ridge, and defeated, the invaders were for the time being held. They claimed some 250,000 prisoners and 1800 guns of every calibre, besides immense quantities of munitions. They had also succeeded in diverting French and British divisions from the Western front, the Allies sending what assistance they could to stave off the defeat of Italy. The French and British troops arrived in time for the winter struggle, which began on 4th Dec., by which time General von Below had returned to France--being succeeded in command of the Austro-German operations by General Krobatin--and General Cadorna had been transferred to the Allied War Council, his place as Italian Commander-in-Chief being taken by General Diaz. Two British divisions, under Cavan, took up their positions in the Italian line at Montella; the French divisions at Monte Tomba; and they served to relieve the pressure while the enemy was making his last efforts to break through before the long-delayed snows put an end to the struggle for the year.

_Naval War in 1917_

At sea, where the British Grand Fleet was now commanded by Sir David Beatty in place of Sir John Jellicoe, who had succeeded Sir Henry Jackson as First Sea Lord in the previous November, the year 1917 passed without a single outstanding engagement. Since Jutland, the German High Seas Fleet had run no risk above water of again seriously challenging Britain's sovereignty of the sea, though her submarine campaign was pursued with ever-increasing vindictiveness. Risking rupture with the United States and other neutrals whose shipping and subjects were thus exposed to wanton attack, she inaugurated 'unrestricted' U-boat war on 1st Feb. "Give us two months of this", said the German Foreign Secretary to the American Ambassador in Berlin, "and we shall end the war and make peace." The argument was that the Allies' losses in tonnage, already more than they could bear, would increase to such an extent that they would be starved into submission. The United States, with President Wilson as spokesman, replied by severing diplomatic relations with Germany, but it was not until 5th April that she formally declared war against her. Cuba followed suit on 5th April; Panama three days later; Brazil on 2nd June. Germany could afford the risk of offending the smaller American republics, but her defiance of the United States was a fatal blunder. She relied on her submarines to prevent the transport of American troops across the Atlantic--at least until they were too late to affect the issue. The first American contingents crossed unharmed and arrived in France on 26th June. It was not until the following year, however, that the new American army was ready to throw its weight into the scales on the Western front. The naval resources of the United States were at once placed at the Allies' disposal, the American destroyer squadron in particular being of great service in helping in the protection of trade off the Irish coast. Proof of the closeness of co-operation between the British and United States navies was afforded in June, 1917, when Vice-Admiral Sims, commanding the United States Naval Forces in European Waters, was given the command of the Irish station during the absence of Vice-Admiral Bayley on sick leave. No foreign naval officer had ever previously held the command of British ships, as well as his own, off the British coast.

Apart from the relentless submarine campaign, which every week exacted heavy toll yet never brought the Allies within measurable distance of the starvation-point to which the Germans had been so sure of reducing them, the enemy's operations at sea were restricted to destroyer and torpedo-boat raids in the Channel from Zeebrugge. Some of these did a certain amount of damage to patrol boats, and bombarded Ramsgate, Broadstairs, and Margate (27th Feb. and 26th April) with little effect save the death of women and children. One memorable incident in these minor operations in 1917 was the raid on Dover on the night of 20th-21st April, when 6 German destroyers, after firing a number of rounds inland, were caught on their way back by the British destroyers _Broke_ (Commander R. G. E. Evans) and _Swift_ (Commander A. M. Peck)--the advance ships of the British destroyer guard in the Straits of Dover. The _Swift_, which was leading, dashed between two of the retreating destroyers and, turning, sent one of them to the bottom with a torpedo. The _Broke_ rammed the third vessel, and while the two ships were locked, an old-fashioned hand-to-hand fight took place on the _Broke's_ forecastle, in which the German crew were beaten back. Two minutes later the _Broke_ wrenched herself free and the German destroyer sank. Ten German officers and 108 men were rescued at the close of this dashing affair.

_1918 on the European Fronts_

_First Phase of Ludendorff's Offensive._--The Bolshevist betrayal of the Allies at Brest-Litovsk, the treaty of which took Russia irrevocably out of the conflict, and released Germany's Eastern forces for a concentrated assault in the West, gave the Central Powers their greatest opportunity of winning the war since their first hopes were shattered on the Marne in 1914. The crushing defeat of Italy at Caporetto afforded them further grounds for confidence. America, it was true, had thrown in her lot on the side of the Allies, but Germany counted on striking her decisive blow before the American troops could arrive in sufficient numbers to matter; and she had not yet lost faith in her submarines. All through the winter of 1917-8 Ludendorff, the German Commander-in-Chief, was secretly training his troops in the new tactics which were to bring open warfare into full play again, equipping them with Teutonic completeness, and massing guns and ammunition proportionate to the task in view.
