the 2nd Portuguese Division suffered 7,000 casualties and 300 officers (out of a divisional strength of 20,000) in the Battle of Estaires. Haking and his Corps "did well" in the halting of this offensive. Haking was not a believer in "defence in depth", but Andy Simpson argues that this was not necessarily a bad thing, as 55th (West Lancashire) Division under his command – fresh troops holding old fortifications – were able to hold their positions and even establish a defensive flank despite the rout of the Portuguese division to their south. Lloyd George told the War Cabinet (11 April) that the Liberal War Committee (a committee of backbench MPs) had made "very serious protests" to him that afternoon against the retention of "incompetent" officers like Gough (who had just been sacked after his Fifth Army had borne the brunt of the German March Offensive) and Haking. Unlike Gough, Haking retained his command. General Gomes da Costa later wrote (in O corpo de exercito portugues na Grande Guerra: A batalha do Lys) of "the esteem in which I held General Haking … who always showed himself through his knowledge of the Portuguese language, extremely intelligent and clever, a fine soldier and a loyal friend". Haking conducted a successful attack at La Bassee in June 1918. Simpson writes that his "performance continued to be far more convincing than earlier in the war". On 17 October 1918 his corps entered the line as part of Birdwood's Fifth Army. Corrigan writes that that autumn Haking "earned a high reputation in the British Offensive which ended the war" whilst Simpson writes that "(h)is promise before the First World War was never realised during it, but he undoubtedly showed far more skill with the soldiers of 1918 than with those under his command in 1915–16". Haking was honoured with the Knight Commander of the Order of St Michael and St George (KCMG) in 1918. Post-war After the war, in Corrigan's view, "his ... career was distinguished": he became chief of the British section of the Armistice Commission in 1918–1919, commander of the British military mission to Russia and the Baltic Provinces in 1919 and commander of Allied troops in the plebiscite area of East Prussia and Danzig in 1920, before becoming High Commissioner to the League of Nations in Danzig in 1921–1923. Haking was appointed Knight Grand Cross of the Order of the British Empire
