12th Infantry Battalion AIF, (TAS) 3rd Brigade, 1st Division

About This Unit

The 12th Battalion was raised to become part of the 3rd Brigade in the 1st Division. Its colour patch tells the story;  the rectangle signifies the 1st Division.  The pale blue lower portion signifies the third brigade in the division.  The white upper signifies the fourth battalion of that brigade.  

The 12th Battalion was drawn largely from Tasmania but about 50% of the unit was comprised of South and Western Australians. Many of the South Australians were from the Port Pirie region in that State's mid North.

The Third Brigade comprised Battalions from the smaller States. It was also destined to be the Covering Force (ie first ashore) at Gallipoli.  The Commanding Officer Lieutenant Colonel L.F. Clark was the first of a significant number of unit COs killed at Gallipoli. He was shot and killed by an enemy sniper within hours of the landing.  

After withdrawal from Gallipoli in December 1915, the Battalion served on the Western Front and participated in fighting at Pozieres / Mouquet Farm, the follow up of the  German consolidation at the Hindenburg Line, where two Victoria Crosses were won by Captain Newand and Sergean Whittle.  The battalion then moved with its parent Brigade to Belgium and the Third Ypres campaign.  The 12th was heavily invovled at Menin Road, in Reserve at Polygon Wood, in supports at Broodseinde took part in Second Passchendaele.

In 1918 the Battalion along with the rest of the 3rd Brigade spent a lot of time in the Flanders area and countered the German April offensive in the Lys, Hazebrouck and Merris sectors.  It took part in the "Last Hundred Days" offensive after being brought south to the Somme.  After fighting near Albert, the Battalion was involved in the final battles of its war around the Hindenburg Line / Epéhy. Operations finished in late September 1918.  The Battalion along with the rest of the AIF was out of the line being reinforced after the losses of the Hundred Days campaign when the Armistice was declared on November 11th 1918.

The men of the 12th Battalion who survived the Great War, like their peers throughout Australia, came home to get on with the rest of their lives. Many didn't last long. The after effects of wounds, gassing, disease, injury and psychological scars all took their toll, often quite quickly. The men formed Associations out of which was spawned organisations like the RSL to look after their injured colleagues and Legacy to take care of the widows and families of the fallen. 

Men of the 12th Battalion were  2 VC; 1 CB; 2 CMG; 5 DSO, 1 bar; 31 MC, 2 bars, 1 2nd bar; 23 DCM, 1 bar; 132 MM, 16 bars, 3 2nd bars; 5 MSM; 59 MID; 8 foreign awards. 

During the course of military service, 1,135 men of the Battalion were killed in action and 2,422 wounded.
