Boer War In late 1899, Antill was promoted to the rank of
major. As part of New South Wales' contribution to the
Boer War, he was placed in command of 'A' Squadron, New South Wales Mounted Rifles, and sent overseas. Antill was present during the
Battle of Paardeberg, which took place on 18 February 1900. He also took part in securing Pretoria and other operations unil he returned to Australia in January 1901. Two months later, he returned to South Africa, this time serving as the second-in-command of the 2nd New South Wales Mounted Rifles. With this force, he took part in the capture of a Boer convoy under the command of
Fedinandus Potgier at the
River Vaal. and achieved the
brevetted rank of
lieutenant colonel. which was finalised the following year. reaching Egypt where the brigade undertook further training. In May, the light horsemen were sent to
Anzac Cove as dismounted reinforcements; initially, Antill's brigade undertook mainly defensive duties. However, in an effort to break the deadlock they were committed to the
August Offensive. During the fierce fighting at
The Nek, Antill, now in temporary command of the brigade, refused a request from the commander of the
10th Light Horse, Lieutenant Colonel
Noel Brazier, to cancel the third wave. Hughes had gone forward to observe the attack, leaving Antill in charge. Due to a communications breakdown, Antill believed Hughes had gone forward to lead the brigade forward and therefore ordered the attack to continue. Part of the fourth wave also went over the top, before Brazier and some officers from the 8th Light Horse Regiment reached Hughes in time to call off any further waves. Out of around 500 men committed to the attack, more than half became casualties, with 234 being killed and 138 wounded. Most of those that were killed, died within only a few metres of the Australian trench line having come under heavy, unsuppressed fire. Antill took over temporary command of the brigade in September 1915 when Hughes became sick and had to be evacuated. when the decision was made by the British high command to evacuate the peninsula. The 3rd Light Horse Brigade were among last troops to withdraw from the position on 20 December 1915. On 1 January 1916, after the light horse units had returned to Egypt, Antill was promoted to the permanent rank of
colonel, and temporary rank of
brigadier general. He was also confirmed in his position as commander of 3rd Light Horse. On 5 August, after an Ottoman force
attacked at Romani, Antill's brigade joined the rest of the
ANZAC Mounted Division east of the canal. They arrived too late to take part in the initial fighting although they were later committed to following up the withdrawing Turkish troops. 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. ==Post-war and later life==
