into the front line, commanded it there throughout its first battle, and remained longer in the field than almost any of the senior militia officers who had left with the original force". Post-war military service After his AIF appointment was terminated, Weir resumed his service in the Citizen Military Forces (CMF). In 1917, he was awarded the Distinguished Service Order and the Russian Empire Order of St. Anne, 2nd Class, with Swords, and was mentioned in dispatches for his performance at Pozières and Mouquet Farm. From 1917 to 1920, he was aide-de-camp to the Governor-General of Australia, Sir Ronald Craufurd Munro Ferguson. Weir retired from the CMF as an honorary brigadier general in March 1921, his last appointment being as commander of the 20th Infantry Brigade. He was only the second South Australia-born officer to reach the rank of brigadier general. On 31 March 1921, Weir was appointed Honorary Colonel of the 10th Battalion, a position he held for many years. Later life Weir had two significant advantages in his return to a civilian career. Firstly, he was repatriated well before most servicemen and, secondly, South Australia had implemented a policy of preferment of returned servicemen for government employment. These circumstances helped him gain appointment as the first South Australian Public Service Commissioner in 1916. Weir was not suited to this role, being unable to navigate the competing personal and political agendas of senior public servants and politicians, and was soon sidelined. In 1925, legislative changes made it possible for the government to replace Weir, and this took place in 1930. In the last year-and-a-half before his retirement in 1931, Weir was the chairman of both the Central Board of Health and the Public Relief Board, excelling at the latter. On 8 June 1923, after many years of poor health, Weir's wife Rosa died. He married Lydia Maria Schrapel in 1926. Weir led an active retirement, contributing to several religious, charitable and welfare organisations and activities. These included the Norwood and Maylands Churches of Christ, Benevolent and Stranger's Friend Society, the Our Boys Institute (OBI), the Masonic Lodge, Cheer-Up Society, and YMCA. At various times he served as President of the Commonwealth Club, the Churches of Christ Union, the St. Peters Sub-Branch of the Returned and Services League, and the Cheer Up Society. Weir wrote the foreword for the history of the 10th Battalion, titled The Fighting 10th: A South
