removed his brigade from action, and delayed his divisional commander, Major General Harry Chauvel, by several hours that proved costly in terms of consolidating the initial gains. Only days after Romani, General William Birdwood sent a message requesting Antill take command of an infantry brigade on the Western Front. Antill accepted the offer, and relinquished command of the 3rd Light Horse Brigade to Brigadier General John Royston on 9 August. On arrival in Europe, Antill was given command over the 2nd Infantry Brigade, taking over in September and overseeing operations around Ypres and on the Somme. However, Antill became ill and had to be evacuated to England in November 1916. He returned to duty on 20 March 1917 at which time he assumed command of the 16th Infantry Brigade, which was being raised within the new 6th Division. The brigade was ultimately disbanded without seeing action, and Antill's health deteriorated. As a result, the medical review board refused to clear him for active duty. After failing his final medical examination he ceased his command on 20 September 1917. He returned to Australia shortly afterwards. For his service during the First World War, Antill was created a Companion of the Order of St Michael and St George in 1916. Post-war and later life On his return to Australia, Antill's appointment to the AIF was terminated in December 1917 and he returned to the permanent forces. He subsequently assumed the role of Assistant Adjutant General in 1918. Later that year, he took over as Commandant of the 5th Military District, in South Australia. He held this position until 1921, when he took up the role of Chief Instructor at the Training Depot, based in Liverpool, New South Wales. On 26 January 1924, Antill retired from the military, with the honorary rank of major general. In retirement, he lived in Jarvisfield, Manly and then Dee Why, and undertook a variety of hobbies including gardening, and sports. In 1936, he co-authored a play called The Emancipist with Rose Antill de Warren, about William Redfern. The final years of his life were spent in ill health, as he was diagnosed with cancer. Antill died on 1 March 1937 at the age of 71. He was cremated. In summarising Antill's character, his biographer Rex Clark in the Australian Dictionary of Biography describes Antill as: Ross Mallett's "General Officers of the First AIF" describes him in the
