struck down by typhoid again on 11 October and evacuated a second time, returning on 23 October 1915. For his services at Anzac, Gellibrand was twice mentioned in despatches, and awarded the Distinguished Service Order. On 4 December 1915, Gellibrand received a promotion to lieutenant colonel, and was given command of the 12th Infantry Battalion, the 1st Division's Tasmanian battalion, then resting on Lemnos. It did not return to Anzac, which was evacuated on 20 December 1915. Instead, the battalion returned to Egypt, arriving at Alexandria on 6 January 1916. Gellibrand would not lead it into battle. On 1 March 1916 he was again promoted, this time to full colonel and temporary brigadier general, and given command of the 6th Infantry Brigade, on the specific request of Legge. Apparently Gellibrand had greatly impressed Legge during his time as AA & QMG of the 2nd Division. The 6th Infantry Brigade sailed for the Western Front just a few days later, on 19 March 1916, and entered the line there on 10 April. On 31 May, Gellibrand was wounded by a German shell that had landed close to his headquarters and was evacuated to England, returning on 28 June. The brigade fought at Pozières, where it performed well in the attack on 4 August. He was mentioned in despatches once more. Gellibrand went to England on leave on 25 November 1916. While there he had four teeth extracted and did not return until December. He was evacuated again on 13 December 1916 with influenza, returning on 30 January 1917. In the meantime he was promoted to brevet major in the British Army's Reserve of Officers List, which he considered an insult. He was acting commander of the 2nd Division until 5 March 1917, directing it in probing attacks against Malt Trench when it was suspected that the Germans were withdrawing to the Hindenburg Line. The advance of the 6th Infantry Brigade to the Hindenburg Line began well but ended with a costly, ill-planned and ill-executed attack on Noreuil. This caused his division commander, Major General Nevill Smyth, and corps commander, Lieutenant General William Birdwood to lose confidence in Gellibrand, although the commander of the British Fifth Army, General Sir Hubert Gough considered it a risk that he had accepted. Gellibrand received a fourth mention in despatches. The 6th Infantry Brigade's next attack was against the Hindenburg Line near Bullecourt, in the Second
