36th Infantry Brigade (United Kingdom) was an infantry formation of the British Army that served in both the First World War and the Second World War, seeing action on the Western Front, in the Middle East, and in the Far East. Formed, disbanded, and reconstituted across periods of mobilization, the brigade was associated with Territorial Force units, Regular Army battalions, and later with divisions engaged in campaigns linked to the British Expeditionary Force, the Egyptian Expeditionary Force, and the British Indian Army.

History

The brigade's origins trace to pre‑First World War Territorial reforms influenced by the Haldane Reforms, which reshaped the British Army and the Territorial Force ahead of the First World War. Mobilized in 1914, the brigade was rebuilt after casualties sustained during the Battle of the Somme and the Third Battle of Ypres, reflecting broader British force rotations during 1916–1918. Between the wars, reductions under the Ten Year Rule and later rearmament policies affected its composition until reactivation prior to the Second World War, when it took part in operations tied to the British Expeditionary Force (World War II), the North African Campaign, and counterinsurgency and garrison duties in Burma Campaign theatres.

Formation and Organization

Initially constituted from Territorial battalions affiliated with county regiments such as the Royal Irish Regiment, the Loyal Regiment (North Lancashire), and other local formations, the brigade's 20th‑century incarnations combined Regular and Territorial infantry battalions alongside machine gun companies and trench mortar units patterned after Army Council directives. Reorganization following the Battle of Loos and the establishment of Machine Gun Corps units altered its internal structure. During the Second World War, the brigade's order reflected Army Council Instruction templates, incorporating anti‑tank platoons, carrier troops from the Royal Tank Regiment, and attached artillery from the Royal Artillery.

Operational Service

On the Western Front the brigade fought in set‑piece engagements including sector actions during the Battle of Arras (1917), defensive operations during the German Spring Offensive (1918), and participation in the Hundred Days Offensive. In the Second World War, elements were deployed with the British India Command and the Middle East Command, undertaking operations during the Anglo‑Iraqi War and later in the Burma Campaign against the Imperial Japanese Army. The brigade's service involved coordination with formations such as the 51st (Highland) Division, the 7th Armoured Division, and multinational commands including units of the Indian Army and the Royal Air Force for close support and logistics.

Commanders

Commanding officers included senior infantry figures drawn from regimental colonels and brigade‑rank officers who previously served in corps and division staff posts influenced by doctrines issued at Staff College, Camberley. Notable commanders were often recipients of decorations like the Order of the Bath, the Distinguished Service Order, and the Military Cross; they had prior service in campaigns such as the Second Boer War and held appointments within the War Office. Leadership changes reflected casualty rates, promotions to corps command, and interwar professional development through the Imperial Defence College.

Insignia and Traditions

The brigade employed unit insignia consistent with divisional signs promulgated by the War Office; shoulder flashes and cap badges often referenced county heraldry tied to parent regiments such as the Lancashire Fusiliers and the Royal Dublin Fusiliers. Regimental colours, battle honours from actions like Ypres, and musical traditions maintained links to local militia antecedents including the Volunteer Force. Ceremonial practices observed at assemblies and memorial services connected the brigade to national commemorations like Remembrance Sunday and monuments maintained by the Commonwealth War Graves Commission.

Order of Battle

Throughout its existence the brigade's constituent units changed frequently. In 1914–1918 typical composition included three to four infantry battalions drawn from regiments such as the Royal Irish Regiment, the Loyal Regiment (North Lancashire), and territorial battalions from counties represented in the Territorial Force. Support elements encompassed machine gun companies of the Machine Gun Corps, trench mortar batteries, and attached field artillery from the Royal Field Artillery. In 1939–1945 formations saw integration with battalions from the King's Regiment (Liverpool), the Queen's Own Royal West Kent Regiment, and colonial units from the Indian Army depending on theater assignments.

Legacy and Reassignments

Post‑war reductions and army reorganizations under the Options for Change and earlier defence white papers led to disbandment, amalgamation, or re‑roling of the brigade's battalions into new brigade groupings and administrative brigades within the British Army of the Rhine and Territorial Army structures. Units formerly assigned to the brigade provided cadres for new regiments and contributed personnel to peacekeeping operations under United Nations mandates and to NATO commitments in West Germany. Memorials in regimental museums and records held at the National Archives (United Kingdom) preserve the brigade's operational history.
