Lieutenant General Samuel Holt Lomax, CB (2 August 1855 – 10 April 1915) was a British Army officer who commanded the 1st Division during the early battles of the First World War.

[17] In late October 1914 the 1st Division was engaged in heavy fighting at the First Battle of Ypres in Belgium, with its headquarters in a chateau at Hooge, recently vacated by Lieutenant General Sir Douglas Haig, commanding I Corps.

[18] During the course of the battle, at a moment of crisis with the 1st Division's line under mounting pressure from a German attack threatening the destruction of the 1st Division and I Corps as a whole and a breach of the line being contested, Lomax received an offer from Haig of reinforcements from I Corps rapidly diminishing reserve troop strength being sent up to his sector to shore up its crumbling defences, Lomax refusing by reply, stating: "More troops now only means more casualties, it is artillery fire that is wanted".

[19] On 31 October 1914, at the height of the battle, with the Germans launching repeated mass man assaults on the weakening British line, supported by concentrated barrages of fire from their artillery, a meeting took place at the chateau H.Q.

[21] General Monro had stepped into another room in the building with his chief of staff just before the shells struck, and survived with minor injuries;[21] however, Lomax was seriously wounded and medically evacuated back to England.

[22] Sir Arthur Conan Doyle later wrote that Lomax's early death in the war had deprived the British high command of a talented general, which "was a brain injury to the Army and a desperately serious one.
