Strategic debates Robertson was a strong supporter of BEF commander
Douglas Haig and was committed to a
Western Front strategy focusing on Germany and was against what he saw as peripheral operations on other fronts. including
George Milne, whom he discouraged from offensive operations at Salonika, and
Frederick Stanley Maude who may have "consciously or unconsciously" ignored his secret orders not to attempt to take Baghdad. In a 12 February 1916 paper Robertson urged that the Allies offer a separate peace to
Turkey, or else offer Turkish territory to
Bulgaria to encourage Bulgaria to make peace. In reply, Sir
Edward Grey pointed out that Britain needed her continental allies more than they needed her, and Britain could not risk them making a compromise peace which left Germany stronger on the continent. The War Committee had only agreed with some reluctance to make preparations for the Western Front Offensive agreed at Chantilly, which Haig and Joffre agreed (14 February) should be on the
Somme. For three months, against a backdrop of Russia planning to
attack earlier than agreed,
Italy reluctant to
attack at all and the scaling-down of the planned French commitment because of
Battle of Verdun, Robertson continued to urge the politicians to agree to the offensive. He increasingly believed that France was becoming exhausted and that Britain would carry an ever greater burden. After Robertson promised that Haig "would not make a fool of himself", the War Committee finally agreed (7 April). Robertson lobbied hard with politicians and the press for the extension of conscription. When the Cabinet finally authorised the Somme Offensive, Robertson had the
Army Council make a statement in favour of conscripting married men. In the face of protests from
Bonar Law that the government might break up, to be followed by a general election and conscription brought in by martial law, Robertson refused to compromise and encouraged
Geoffrey Dawson, editor of
The Times, to make his stance public. At first Robertson tried to limit information to the War Committee only to a summary of news, most of which had already appeared in the newspapers – this was stopped by Hankey and Lloyd George when it was discovered that Robertson had moved troops from Egypt and Britain to France with little reference to the War Committee. In late May Haig and Robertson also angered ministers by challenging their right to inquire into the shipping of animal fodder to France. Robertson was promoted to permanent general on 3 June 1916. At an Anglo-French conference at
10 Downing Street Robertson finally succeeded in blocking a major offensive from Salonika. Robertson lobbied hard but in vain to prevent Lloyd George, who made no secret of his desire to use his control over military appointments to influence strategy, from succeeding Kitchener as Secretary of State for War. Although Robertson retained the special powers he had been granted in December 1915, and
Edward Stanley, 17th Earl of Derby, an ally of the soldiers, was appointed Under-Secretary, Robertson still wrote to Kiggell "That d----d fellow L.G. is coming here I fear. I shall have an awful time".
The Somme Robertson had been clear that it would take more than one battle to defeat Germany, but like many British generals he overestimated the chances of success on the Somme. Robertson also wrote to Kiggell (Chief of Staff BEF) stressing that "the road to success lies through deliberation". He recommended "concentration and not dispersion of artillery fire" and "the thing is to advance along a wide front, step by step to very limited and moderate objectives, and to forbid going beyond those objectives until all have been reached by the troops engaged". Kiggell conceded that there had been problems with infantry-artillery coordination, but seemed more concerned with the slowness of progress. Henry Wilson recorded rumours that Robertson was angling for Haig's job in July, although there is no clear evidence that this was so. Robertson complained that Haig's daily telegrams to him contained little more information than the daily press releases.
F. E. Smith (1 August) circulated a paper by his friend Winston Churchill criticising the high losses and negligible gains of the Somme. Churchill argued that this would leave Germany freer to win victories elsewhere. Robertson issued a strong rebuttal the same day, arguing that Britain's losses were small compared to what France had suffered in previous years, that Germany had had to quadruple the number of her divisions on the Somme sector and that this had taken pressure off Verdun and contributed to the success of
Russian and
Italian offensives. With Allied offensives apparently making progress on all fronts in August, Robertson hoped that Germany might sue for peace at any time and urged the government to pay more attention to drawing up war aims, lest Britain get a raw deal in the face of collusion between France and Russia. Prompted by Asquith, Robertson submitted a memorandum on war aims (31 August). He wanted Germany preserved as a major power as a block to Russian influence, possibly gaining
Austria to compensate for the loss of
her colonies,
Alsace-Lorraine and her North Sea and Baltic ports.
Clash with Lloyd George Robertson correctly guessed that the
Bulgarian declaration of war on
Romania (1 September) indicated that they had been promised German aid. While Lloyd George, who wanted
Greece to be brought into the war on the Allied side, if necessary by a naval bombardment, was visiting the Western Front Robertson persuaded the War Committee that Romania was best helped by renewed attacks on the Somme. Robertson had told
Charles Monro, the new
Commander-in-Chief India, to "keep up a good show" (1 August 1916) in Mesopotamia but wanted to retreat from
Kut to
Amara rather than make any further attempt to take
Baghdad; this was overruled by
Lord Curzon and
Austen Chamberlain. Lloyd George criticised Haig to
Ferdinand Foch on a visit to the Western Front in September, and proposed sending Robertson on a mission to persuade Russia to make the maximum possible effort. With royal backing, Robertson refused to go, later writing to Haig that it had been an excuse for Lloyd George to "become top dog" and "have his wicked way". Lloyd George continued to demand that aid be sent to help Romania, eventually demanding that 8 British divisions be sent to Salonika. This was logistically impossible, but to Robertson's anger the War Committee instructed him to consult Joffre. Derby dissuaded him from resigning the next day, but instead he wrote a long letter to Lloyd George complaining that Lloyd George was offering strategic advice contrary to his own and seeking the advice of a foreign general, and threatening to resign. Lloyd George had to give his "word of honour" to Asquith that he had complete confidence in Haig and Robertson and thought them irreplaceable. However, he wrote to Robertson wanting to know how their differences had been leaked to the press and asserting his right to express his opinions about strategy. The Army Council went on record forbidding unauthorised press contacts, although that did nothing to stop War Office leaks.
The Somme ends At the inter-Allied conference at Boulogne (20 October) Asquith supported Robertson in opposing major offensives at Salonika. Robertson wrote to Repington "If I were not in my present position I daresay I could find half a dozen different ways of rapidly winning this war". He advised Hankey that further high casualties would be needed to defeat Germany's reserves. Robertson wanted industrial conscription, national service for men up the age of 55, and 900,000 new army recruits, similar to the new German
Hindenburg Programme. He was concerned at the Asquith Coalition's lack of firm leadership, once likening the Cabinet to "a committee of lunatics", and although he avoided taking sides in party politics he urged the creation of a small War Committee which would simply give orders to the departmental ministers, and was concerned (letter to Hankey, 9 November) that ministers might be tempted to make peace or to reduce Britain's Western Front commitment. Robertson gave an abusive response to the
Lansdowne letter (13 November 1916) (calling those who wanted to make peace "cranks, cowards and philosophers"). Robertson successfully lobbied Joffre and at the Chantilly Conference (15–16 November 1916) Joffre and Robertson (in Haig's view) "crushed" Lloyd George's proposal to send greater resources to Salonika. The Somme ended on 18 November. There was already divergence between MacDonogh and Charteris as to the likelihood of German collapse. Robertson shocked ministers by forecasting that the war would not end until summer 1918. On 21 November, Asquith again met ministers without Robertson present, and they agreed they could not order him to go to Russia. His influence was already beginning to wane. At the second Chantilly Conference it had been agreed that Britain would in future take a greater share of the war on the Western Front. Asquith had written to Robertson of the War Committee's unanimous approval of the desirability of capturing or rendering inoperable the submarine and destroyer bases at
Ostend and
Zeebrugge. Haig and Robertson had obtained Joffre's approval for a British Flanders Offensive, after wearing-out attacks by Britain and France.
Lloyd George becomes prime minister During the December political crisis Robertson advised Lloyd George to form a three-man War Council, which would probably include the
Foreign Secretary but not the
First Lord of the Admiralty or the
Secretary of State for War. He was suspected of briefing the press against Asquith, and had to assure the Palace that this was not so. Robertson warned the first meeting of the new five-man War Cabinet against the danger of "sideshows". By contrast Hankey advised sending aid to Italy and offensives in Palestine – Lloyd George used this as the blueprint of future strategy discussions. With Murray's support, in the autumn of 1916 Robertson had resisted attempts to send as many as 4,000 men to
Rabegh to help the nascent
Arab Revolt, stressing that logistical support would bring the total up to 16,000 men, enough to prevent Murray's advance on El
Arish. Robertson accused the ministers of "attaching as much importance to a few scallywags in Arabia as I imagine they did to the
German attack on Ypres two years ago", but for the first time ministers contemplated overruling him. Encouraged by hope that the Russians might advance to
Mosul, removing any Turkish threat to Mesopotamia, Robertson authorised Maude to attack in December 1916. ==CIGS: Spring 1917==
