New Zealand and Australian Division

The New Zealand and Australian Division was a combined infantry formation raised in 1915 from contingents of New Zealand and Australia for service in the First World War. Formed for operations in the Gallipoli Campaign, the division drew personnel from the Australian Imperial Force, the New Zealand Expeditionary Force, and associated medical and logistics units, and served alongside formations such as the British 29th Division, the Royal Naval Division, and the ANZAC Mounted Division. Its establishment reflected pre-war ties between Wellington and Canberra, shared colonial military traditions, and coordination between expeditionary staffs led by figures like Alexander Godley and William Birdwood.

Background and Formation

Plans for an Australasian expeditionary force were influenced by pre-war imperial defence discussions involving Imperial Conference (1909), the Committee of Imperial Defence, and colonial military authorities in Australia and New Zealand. Mobilisation followed declarations by King George V and directives from the War Office and Imperial General Staff. The division assembled units already committed to the Mediterranean Expeditionary Force, integrating brigades formerly under separate commands such as the 1st Australian Division, the 2nd Australian Division, and the New Zealand Infantry Brigade. Senior appointments included staff coordination with officers from the Australian Army Medical Corps, the New Zealand Army Ordnance Corps, and liaison with the Royal Navy and Royal Flying Corps elements operating in the theatre.

Operational History

The division's operational history is dominated by its role during the Gallipoli Campaign, where it participated in amphibious landings, trench operations, and assaults on well-defended positions like Achi Baba and Chunuk Bair. It operated in conjunction with formations such as the 29th Division (United Kingdom), the 29th Division, and the Royal Naval Division under the overall command once exercised by Lieutenant General Sir Ian Hamilton. Its activities included holding sectors on the Anzac Cove front, conducting patrolling, and mounting limited offensives during the August 1915 battles tied to the Suvla Bay operations and the Battle of Sari Bair. Logistical support was coordinated with the Mediterranean Expeditionary Force base at Mudros and hospitals at Alexandria and aboard hospital ships like those administered by the Australian Red Cross.

Organization and Command Structure

At formation, the division's order of battle combined the New Zealand Infantry Brigade with Australian brigades drawn from the Australian Imperial Force numbered within the expedition. Command arrangements saw a dual-nationality staff under divisional commanders reporting to the corps and army commanders of the Mediterranean Expeditionary Force. Key staff appointments included liaison officers from the Royal Army Medical Corps, signals elements interacting with the Royal Engineers, and artillery coordination with batteries from the Royal Horse Artillery and colonial artillery units. Tactical control often required coordination with naval gunfire provided by ships of the Royal Navy such as elements coordinated through the Admiralty. Prominent commanders and staff officers included figures linked to pre-war colonial forces like the New Zealand Defence Force and the Australian Military Forces.

Deployments and Engagements

The division's primary deployment was to the Gallipoli Peninsula in April 1915, where it landed at Anzac Cove and fought in the sequence of actions culminating in the August Offensive including assaults on Chunuk Bair and Hill 971. It undertook trench raids, defensive operations against Ottoman formations such as units from the Ottoman Army, and withdrawal operations during the eventual evacuation ordered by the Mediterranean Expeditionary Force command under political pressure from capitals including London. Engagements involved cooperation with allied formations including the French Expeditionary Corps and logistics coordination with bases on Crete and Imbros as staging areas. The division also provided cadres and replacements to subsequent formations serving on the Western Front, including elements integrated into the Australian Corps and the New Zealand Division redeployed to France.

Casualties and Commendations

Operational casualties were significant during the Gallipoli operations, with losses from combat, disease, and the harsh ANZAC sector conditions. Wounded and killed were evacuated to treatment facilities such as the hospitals at Alexandria, aboard hospital ships, and to convalescent depots in Malta. Individuals from the division received awards conferred by institutions including the Victoria Cross and mentions in despatches authored by commanders like William Birdwood and Ian Hamilton. Unit-level commendations and posthumous recognitions were recorded in official lists maintained by the Australian War Memorial and the Auckland War Memorial Museum, and detailed in the casualty rolls produced by the Commonwealth War Graves Commission.

Post-war Legacy and Commemoration

The division's legacy is memorialised through commemorative practices in cities such as Auckland, Sydney, Melbourne, and Canberra, with monuments, rolls of honour, and ANZAC Day ceremonies maintained by organisations including the Returned and Services League of Australia and the Royal New Zealand Returned and Services' Association. Scholarly and popular histories published by presses such as the Oxford University Press and the Auckland University Press analyse the division's contribution alongside broader studies of the Gallipoli Campaign, the Australian Imperial Force, and the New Zealand Expeditionary Force. Archives and museums—Australian War Memorial, Pukeahu National War Memorial Park, and regimental museums—preserve service records, diaries, and artefacts, while battlefield preservation efforts on the Gallipoli Peninsula engage historians from institutions like the University of Canterbury and the University of Sydney.
