This is the order of battle for the Battle of the Somme. The Battle of the Somme was an offensive fought on the Western Front during World War I from 1 July to 18 November 1916 as one of the greatest engagements of the war. It was fought between French, British and Dominion forces and the German Empire in the Somme River valley and vicinity in northern France.

Background

British and Dominion forces

In typical British county regiments, the 1st and 2nd Battalions were regular army, the 3rd was the special reserve battalion which did not normally serve overseas but remained at home as the regimental depot and training unit, from which replacements were sent to the regular battalions. The 4th, 5th and 6th Battalions were normally Territorial Force battalions. Amongst the terms of service in the Territorial Force, service outside the United Kingdom was voluntary. Territorial battalions raised second line battalions which would be numbered 2/4th, 2/5th and 2/6th, initially from men who declined to volunteer for overseas service. The number of battalions depended on the recruitment potential of the area from which the battalions were raised (the Dorsetshire Regiment raised eleven battalions, whilst the London Regiment managed to raise eighty-eight battalions).^[1] Regular army divisions were numbered 1st to 8th. "New Army" divisions of Kitchener's Army raised after the outbreak of war were numbered 9th to 26th. The 27th to 29th Divisions were Regular army divisions made up from units recalled from garrisons around the empire. The 30th to 41st were New Army and the 42nd to 74th were Territorial. The 63rd Division (Royal Naval Division) was made up from Naval Reserves and did not follow this numbering pattern.^[2]

Royal Flying Corps

French forces

A majority of the French Divisions were triangular divisions – comprising three regiments, with each regiment containing three battalions. During the Battle of Verdun, General Pétain had rotated the French Divisions through the battle – resulting in a large number of divisions entering the Battle of the Somme with experience.
