About This Unit

Big thumb 3831054

Raised as the Siege Artillery Brigade (Heavy) in Victoria in April 1915, the troops embarked and departed Melbourne on the Orsova on 17 July 1915.  Like many artillery units it underwent a bewildering sequence of renaming and re-designations; O Siege Brigade 28 September 1915, 36th Heavy Artillery Group 18 July 1916, 36th Heavy Artillery Brigade 5 February 1918. 

The 36th Australian Heavy Artillery Group served in England, and on the Western Front

It was organised in two batteries, equipped with 8 inch Howitzers and 9.2 inch howitzers respectively - the 54th and 55th.  Each battery initially had four guns; this was later increased to six.

These were the heaviest guns operated on a continuous basis by Australian gunners in WW1 (and subsequently).  Heavy artillery was designed to pulverise enemy defensive positions.  By and large German defences were constructed very well indeed, and the onus was on the Allies to attack them to retake ground occupied by the Germans in 1914.  German defences often comprising concrete blockhouses and deep underground concrete dugouts which were impervious to Field Artilley.

Big guns were a prime target for opposing artillerymen who would seek to apply counter battery fire to enemy gun positions.  Locating them accurately was a story in itself.  IN the end it was the British who triumphed thanks largely to the work of Australian born (Professor and Nobel Prize winner) Captain Lawrence Bragg, serving in the Royal Artillery.  He and his team developed a surprisingly accurate technique based on sound ranging that gave the Alliesa decisive advantage being able to locate enemy heavy guns with remarkable accuracy.

Gunners have four defensive measures;  distance from the enemy, concealment, protection in the form of dugouts and bunkers, and mobility.  These guns were not mobile - they could not easily be redeployed.  When one of these guns went off, the entire neighbourhood knew it;  concealment was therefore moot. Defensive earthworks would not sustain a direct hit by enemy heavy artillery.  As far as range was concerned - if the enemy is in range so are you.  In summary, being a gunner was not without risk.

The Australian Heavy Batteries served on the Western Front largely detached from the rest of the AIF.  They spent realtively little time on the Somme.  Most of their service was rendered further north around Arras and Vimy in France and into Flanders.  The Heavy Batteries were manned at the outset with soldiers from the permanent force Garrison Artillery, later augmented by reinforcements from the militia. 


Napoleon Bonaparte famously described Artillery as "the God of War" because of the effect that its fire can bring to bear on the battlefield.  In WW 1 on the Western Front, artillery dominated and defined the battlefield. In concert with the weather, it turned the terrain into the pulverised devastated quagmire that is so synonymous with that period and place. 

Artillery inflicted the most casualties and battle space damage and instilled the most fear among opposing forces. Its effect was both physical and psychological, with the term 'shell shock' coming into general use early in the war.  Artillery required a Herculean logistic effort to keep ammunition up to the guns from manufacture to the gun line. It was also a very dangerous occupation, attracting the attention of the enemy, the general result of which was 'counter battery fire' designed to neutralise and destroy gun positions and ammunition.

The standard organisation of Field Artillery took on the form of the Field Artillery Brigade which were formed to support infantry Brigades. In 1914 and 1915 the First and Second Division each had three brigades (initially corresponding to the Brigade numeric designation) equipped with 12 x 18 pounder field guns.  On arrival in France, the artillery was reorganised with each field artillery brigade having 12 x 18 pounders and 4 x 4.5 inch howitzers. There was initially a lack of howitzers available to meet the establishment.

Each Brigade generally comprised three Batteries of four 18 Pounder Mk 1 or II guns. With a range of about 6,500 yards (almost 6km) they fired a range of ammunition natures including High Explosive fragmentation, Shrapnel, Smoke, Gas, Star (illumination) and Armour Piercing projectiles.  For the record, most gas used in WW1was fired from specialised low velocity projectors operated by Engineers.

However, these guns did not have the power required to disrupt major defensive positions.  Heavier weapons were required.  So the Heavy and Siege Artillery batteries were formed.

The personnel for these units were drawn initially from the permanent garrison artillery that manned forts around the coast of Australia.

As the war progressed, concentration of became the name of the game to facilitate command and control at the highest level.  Siege Artillery, Heavy Howitzers and Medium and Heavy Mortars were added to the mix at Division level or higher.  The allocation of their fire support was managed accordingly.  See the entry for Divisional artillery for further information.
