Army Cyclist Corps

The Army Cyclist Corps was a corps of the British Army active during the First World War, and controlling the Army's bicycle infantry.

Volunteer cyclist units had been formed as early as the 1880s, with the first complete bicycle unit (the 26th Middlesex Rifle Volunteers) being raised in 1888. Cyclists were employed on an intermittent basis during the South African War - whilst they were not deployed as organised combat formations, the bicycle was found to be invaluable for reconnaissance and communications work, being lighter, quieter, and logistically much easier to support than horses. When the Haldane reforms in 1908 reorganised the volunteers into the Territorial Force, nine battalions of cyclists were formed - one from the 26th Middlesex, five from volunteer infantry battalions, and three newly raised.


 * 25th (County of London) Cyclist Battalion, The London Regiment (from the 26th Middlesex)
 * 10th (Cyclist) Battalion, The Royal Scots
 * 5th (Cyclist) Battalion, The East Yorkshire Regiment
 * 8th (Cyclist) Battalion, The Royal Highland Regiment (The Black Watch); later the Highland Cyclist Battalion
 * 6th (Cyclist) Battalion, The Norfolk Regiment
 * 7th (Cyclist) Battalion, The Welsh Regiment
 * 8th (Cyclist) Battalion, The Northumberland Fusiliers; later the Northern Cyclist Battalion
 * 6th (Cyclist) Battalion, The Queen's Own (Royal West Kent Regiment); later the Kent Cyclist Battalion
 * The Essex and Suffolk Cyclist Battalion

A tenth, the 7th (Cyclist) Battalion, The Devonshire Regiment, was raised later in 1908; in 1910, the Essex and Suffolk Cyclist Battalion split into the 8th (Cyclist) Battalion, The Essex Regiment and the 6th (Cyclist) Battalion, The Suffolk Regiment; in 1911, the 6th (Cyclist) Battalion, The Royal Sussex Regiment and 9th (Cyclist) Battalion, The Hampshire Regiment were formed; and in early 1914, the Huntingdonshire Cyclist Battalion was formed. On the eve of the First World War, the Territorial Force thus stood at a strength of fourteen cyclist battalions. Ten of these were Territorial battalions of regular infantry regiments, whilst four - the Huntingdonshire, Highland, Northern and Kent Cyclists - were independent battalions without regimental affiliation.

None of the territorial units saw service overseas in the first months of the war, all being used for coastal defence work inside the United Kingdom. In 1915, the Army Cyclist Corps was founded to encompass these battalions; it later extended to cover a dozen more battalions raised from second-line yeomanry regiments which had been converted to cyclists.

Most units of the Corps served out their time in the United Kingdom, providing replacement drafts to infantry battalions; some were converted back to conventional infantry and saw active service, such as the Kent Cyclists (on the North-West Frontier) or the 10th Royal Scots (in northern Russia).

Formed units of the Corps were not sent overseas; this was done in small groups of men, with the divisions possessing individual cyclist companies and composite battalions later formed at corps level. These were rarely committed to action, rather being held back in preparation for the resumption of "normal" mobile warfare. Cyclists were employed in combat, but in conditions of trench warfare they were generally found to be ineffective. In 1918, however, with the deadlock of the trenches overcome, cyclists once more proved invaluable for reconnaissance.

Two battalions, 25th (County of London) Cyclist Battalion and the Kent Cyclist Battalion fought in the third Anglo-Afghan War.However, the Corps was disbanded in 1920; by 1922 all remaining Territorial cyclist battalions had been converted back to conventional units.
