4th Division (Australia)

The Australian 4th Division was formed in the First World War during the expansion of the Australian Imperial Force infantry brigades in February 1916. In addition to the experienced 4th Brigade (previously in the original New Zealand and Australian Division) were added the new 12th and 13th Brigades (spawned from the battalions of the 4th and 3rd Brigades respectively). From Egypt the division was sent to France.

After the war ended and the AIF was demobilised, the 4th Division name was revived and assigned to an Australian Citizens Military Forces (reserve) unit.

World War I unit history

ThThe division was initially stationed on the Suez Canal. In June 1916 it moved to France, taking over part of the "nursery" sector near Armentieres. Its stay there was brief and soon it was accompanying the First and Second Divisions to the Somme sector. In August 1916 it relieved the Second Division on the Pozieres Heights and repulsed a major German counterattack. It then drove north to the outskirts of Mouquet Farm. A second tour of the Somme at Mouquet Farm followed in September and a third at Flers in October.

On 11 April 1917 the Fourth Division assaulted the Hindenburg Line in the First Battle of Bullecourt. The battle was a disaster and 1170 Australian prisoners were taken by the Germans. In June it participated in the Battle of Messines. In September it participated in the Battle of Polygon Wood.

In March 1918 the Fourth Division was rushed to the Somme region to stem the German Offensive. There it repulsed the advancing Germans in hard fought battles at Hebuterne and Dernancourt. In April its 13th Infantry Brigade was involved in the counterattack at Villers-Bretonneux.

The Fourth Division went on to fight in the Battle of Hamel, Battle of Epehy (with distinction), Battle of Amiens and the Hindenburg Line, finally reaching the town of Bellenglise.

After World War I

In 1921, the 4th Division name was revived and was assigned to an Australian Citizens Military Forces (reserve) unit, elements of which served in the South West Pacific Area during World War II.
