their Hundred Days Offensive, which ultimately brought an end to the war. On the opening day of the offensive, the 26th led the 7th Brigade's attack around Villers-Bretonneux. After a period in reserve, in late August they advanced on the brigade's left during an attack at Biaches which saw the Allies push towards the Somme River. The following month they took part in the attack on Mont St Quentin, during which they experienced heavy machine-gun fire. After the Somme was crossed, the 26th joined an attack around Grandcourt and Lormisset on 3 October 1918, part of the "Beaurevoir Line", which was the third and final line of the Hindenburg Line defences. During the attack, the 26th followed up the initial gains made in the 7th Brigade's sector by the 25th Battalion, and attacked the second line of German defences around Grandcourt, suffering 123 casualties, including 21 killed. Shortly after this, the 26th received a batch of reinforcements from the 25th Battalion, which was subsequently disbanded. Nevertheless, the fighting along the Beaurevoir Line was the 26th Battalion's last contribution to the war and they were withdrawn to Berteaucort for a rest shortly afterwards. They did not return to the front line before the armistice was declared in November and were subsequently disbanded on 31 May 1919. The battalion's last commanding officer was Lieutenant Colonel William Davis, who took command of the battalion in mid-October 1918 and remained in command until it was disbanded. During the course of the 26th Battalion's involvement in the war it lost 877 men killed and 2,745 men wounded. Members of the battalion received the following decorations: two Victoria Crosses (VCs), one Member of the Order of the British Empire (MBE), four Distinguished Service Orders (DSOs) including one Bar, 25 Distinguished Conduct Medals (DCMs), 26 Military Crosses (MCs) including three Bars, 96 Military Medals (MMs) including four Bars, four Meritorious Service Medals (MSMs), and 37 Mentions in Despatches (MIDs). Inter-war years In 1921, following the completion of the demobilisation process, the AIF was disbanded and the Citizens Forces, Australia's part-time military force which was responsible for the defence of Australia, was reorganised to perpetuate the battle honours and traditions of the AIF by renumbering the units of the Citizens Force to adopt the numerical designations of their related AIF units. This process had partially commenced in late 1918, with the introduction of a regimental system within the
