In 1895, Brett became
Permanent Secretary to the
Office of Works, where
Edward, Prince of Wales, was impressed by his zeal and dedication to the elderly
Queen Victoria. After Edward's
coronation in 1902, he gained greater royal influence and shunned political office; by the end of 1903, he met or corresponded with Edward VII daily and meeting with the King's adviser
Lord Knollys three to four times daily.
Esher Report and military influence From 1903, Esher was a member of
Lord Elgin's South African War Commission, which investigated the
British Army's near-failure in the Boer War. In that role, he informed the King of the views of the commission, party leaders, and
War Office civil servants with whom he was still in touch from his days working for Hartington, who had in 1891 become 8th Duke of Devonshire.
Secretary of State for War St John Brodrick was resentful of Esher's influence, which paralysed Brodrick's scope for operation, On 7 December, Arnold-Foster advised the
militia must be absorbed into the Army to save £2,000,000. Encouraged by the King, Esher wanted prime minister
Arthur Balfour to look to party first, while at the same time warning the King's Secretary that, "the Prime Minister will have to take matters into his own hands". Esher's role, playing both Crown and Parliament against each other by confidential memoranda was kept secret for sixty-seven years. It was decided on 19 December a Reserve Force should be set up "in commission". On 12 January, Esher told the minister to accept his sub-committee's recommendation, even though Arnold-Foster had not even been told of the agenda. Despite the intrigues, the King approved of the committee's work. The sub-committee produced the
Esher Report in February and March 1904, recommending radical reform of the British Army, including the establishment of the
Army Council and the
Committee of Imperial Defence, a permanent secretariat. The King successfully urged adoption of its recommended reforms by Prime Minister
Arthur Balfour. Esher cultivated a friendship with Colonel Sir Edmund Ward, secretary to the
Army Council, in order to control minute-taking, the Council agenda, and quorum at meetings. In 1904, Esher told Ward he had "proof of the Army Order" and a plan toward Army decentralisation, called "Traverse". Believing the
royal prerogative had been circumvented "without reference to the Sovereign", Esher marched into Arnold-Foster's office to remind him that precedent under Victoria had been to yield to arguments from the monarch, which had already been put forward by the Adjutant-General. After 1904, all War Office appointments were approved and often suggested by Esher. He approved the establishment of the
Territorial Force, although he saw it as a step toward conscription, a step not taken. Many of Esher's recommendations were implemented between 1905 and 1918 under Secretary of State for War
Richard Haldane, assisted by Esher's protégé, the young Major-General
Douglas Haig. Esher's biographer Peter Fraser thus argued "the
Haldane reforms owed little to Haldane." Although Edward VII urged Esher's appointment as Secretary of State for War, he declined it, along with many other public offices, including the
Viceroyalty of India. He gained a reputation as a disciple of national efficiency, an able administrator, and a silky, smooth influence as a courtier. He was accused of being an arch-insider, undemocratic and interfering. However, the King favoured Esher, and his influence over the Army grew, with a focus on to averting conflict in Europe. Despite his close political connections, including
Lord Tweedmouth and
Lord Rosebery, his undemocratic reputation and ties to the monarch prevented further political ambition or any high cabinet office. He founded the Society of Islanders, established on the principle of "two for one Keels", an expression of British naval supremacy in order to maintain global peace. Esher's involvements in the Territorials were not limited to the War Office. He was the first chairman appointed in 1908 to the County of London Territorial Forces Association and its president from 1912 to his death, in addition he was appointed
Honorary Colonel of the 5th (Reserve) Battalion of the
Royal Fusiliers in 1908 and held the same appointment with the
6th County of London Brigade, Royal Field Artillery, from 1910 to 1921. In 1911, Esher helped ease out Lord Knollys, who was then seventy-five years old and a member of the Royal Household since 1862, but who had lost royal confidence over his negotiation of the
Parliament Act 1911. Esher arranged
Lord Stamfordham as his replacement.
Great War After the outbreak of the
First World War, Esher served as an emissary to France and often travelled to France as a respite from the "mephitic" atmosphere of the War Office. In one writer's description, Esher served as
de facto head of British Intelligence in France, reporting on the French domestic and political situation, although he told his son he preferred not to have a formal position where he would have to take orders. Following the Russian defeats on the Eastern Front,
H. H. Asquith's neutrality over Briand's Salonica Plan perplexed Esher, and he perceived the balance of power in cabinet shifting toward a more conservative coalition. He also made contact in Paris with
Maurice Bunau-Varilla, owner and editor of
Le Matin, with the intent of influencing the
Russian Empire to remain in
the Allied Forces and the United States to join. By 1916, however, the French war effort was almost spent, and Esher reported that Finance Minister
Alexandre Ribot sought to sue for peace. At the
Chantilly Conference, they discussed combined operations to maintain the momentum. Esher accompanied Haig to the Amiens Conference, but on his return to Paris, was informed of the sinking of the
HMS Hampshire and death of
Earl Kitchener. Returning to London, Esher spoke with Prime Minister of Australia
Billy Hughes. The following month at the Beaugency Conference, they discussed the
Somme Offensive. Esher told
Maurice Hankey, "For heaven's sake put every ounce you have got of will power into this offensive." He also learnt firsthand the French government's scheme for a "Greater Syria" to include British controlled Palestine. In 1917, he told Lloyd George, now Prime Minister, that diplomacy in Paris was weak and that Lloyd George "was badly served". Ambassador
Lord Bertie was the last of the Victorian imperial envoys and Esher argued he had failed to do enough to persuade France to remain in the war. When offered the ambassadorship himself, Esher crowed, "I cannot imagine anything I would detest more." Following a
French mutiny the next month, Haig and
Henry Wilson lent support to an offensive to bolster the French.
Philippe Pétain, the new French commander-in-chief, was deemed too defensive, and Esher sent
Charles à Court Repington on a "charm offensive". With support from
Minister of Munitions Winston Churchill and
Lord Milner for dramatic action, Esher entered diplomatic conversation with the
War Policy Committee, a unique departure in the management of British policy. However, bad weather and sickness of war made Esher ill in 1917, and he was encouraged by
King George V to holiday at
Biarritz. Partly on Esher's advice, the War Office undertook major re-organization in 1917, unifying all British military commands at the Imperial War Office. Esher was at the famous Crillon Club dinner meeting in Paris on 1 December 1917, at which with
Georges Clemenceau, they took critical decisions over the strategy for 1918. The Allied Governments proposed a unified Allied Reserve, despite negative press and publicity in the Commons. As cabinet enforcer, Esher visited Henry Wilson on 9 February 1918, during the crisis over his succession to
William Robertson as
Chief of the Imperial General Staff. Esher became instrumental in remonstrating against the war effort with loose press articles in
Lord Northcliffe's newspapers and
The Morning Post. In France, Esher established a
rapprochement with the press to help hold the Clemenceau government together, at a time when England was at the zenith of her military strength. As the war concluded, Esher learned that the King wanted his resignation as Deputy-Governor of Windsor. In fact, he coveted the post of
Keeper of the Royal Archives. Lord Stamfordham demanded his resignation in favour of historian Sir
John Fortescue, but Esher remained as Governor. Professionalization also warned Maurice Hankey against becoming secretary to the
Paris Peace Conference, which to Esher's mind was beyond his competence. Esher also persuaded his friend not to desert the
British Empire for the
League of Nations. Domestic unrest and
trade unionism, which Esher loathed, as it threatened peace and stability, also destabilized his position as President of the Army of India Committee. Ever skeptical of political changes, "omnivorous" introductions to the Viceroy's work forced him to decline a solicitous offer to chair a sub-committee of the Conditions of the Poor.
Post-war work Esher was sworn of the
Privy Council in 1922. In 1928 he became
Constable and Governor of Windsor Castle, an office he had always wanted, holding it until his death in 1930. Lord Esher was also a historian; besides the aforementioned work, he also published works on
King Edward VII and
Lord Kitchener. In February 1920, he proofread Haig's
History of the General Head Quarters 1917–1918. That summer, Esher's critique of a
Life of Disraeli appeared in
Quarterly Review. His memoir, ''Cloud-capp'd Towers
, was published in 1927. After his death, his sons published four volumes of his Journals and Letters'' (1934–1938). == Honours and arms ==
