3rd (United Kingdom) Division

The 3rd (United Kingdom) Division, known at various times as the Iron Division, 3rd (Iron) Division or as Iron Sides; is a regular army division of the British Army. It was created in 1809 by Arthur Wellesley, 1st Duke of Wellington, as part of the Anglo-Portuguese Army, for service in the Peninsular War, and was known as the Fighting 3rd under Sir Thomas Picton during the Napoleonic Wars. The division is also sometimes referred to as the Iron Division, a nickname earned during the bitter fighting of 1916, during the First World War. The division's other battle honours include: the Battle of Waterloo, the Crimean War, the Second Boer War, the Battle of France (1940) and D-Day (1944). It was commanded for a time, during the Second World War, by Bernard Montgomery. The division was to have been part of a proposed Commonwealth Corps, formed for a planned invasion of Japan in 1945-46, and later served in British Mandate Palestine.

During the Second World War, the insignia became the "pattern of three" — a black triangle trisected by an inverted red triangle.

Peninsular War
The Division was part of the British forces that took part in the Peninsular War and fought in the Battle of Sabugal, Battle of Orthez, Siege of Badajoz (1812), Battle of Salamanca, Battle of Nivelle, Battle of Fuentes de Oñoro, Battle of Vitoria, Battle of Bussaco and the Battle of the Pyrenees

Peninsular War Formation
Battle of Vitoria example

Commanding General: Lieutenant-General Sir Thomas Picton (7,500) According to Picton, the fighting by the 3rd was so intense at the Battle of Vitoria, that the division lost 1,800 men (over one third of all Allied losses at the battle) having taken a key bridge and village, where they were subjected to fire by 40 to 50 cannons, and a counter-attack on the right flank (which was open because the rest of the army had not kept pace). The 3rd held their ground and pushed on with other divisions to capture the village of Arinez.

First World War
During the First World War it was a permanently established Regular Army division that was amongst the first to be sent to France at the outbreak of the war. It served on the Western Front for four years. During this time, it was nicknamed "The Iron Division". Its first commander during the war, Major-General Hubert Hamilton, was killed by shellfire near Béthune in October 1914.

The brigade joined the division from the 25th Division in October 1915.

After the end of the First World War, the division was stationed in southern England where it formed part of Southern Command. In 1937, one of its brigades was commanded by Bernard Montgomery. He assumed command of the division shortly before Britain declared war on Germany.

Second World War
The Division was part of the ill-fated British Expeditionary Force evacuated from Dunkirk early in the Second World War but suffered comparatively few casualties. At the time, it was commanded by Major-General Bernard Montgomery, future commander of the British Army in the North-West Europe Campaign in 1944 after D-Day.

Composition 1939–40
From the outbreak of war until the Dunkirk evacuation the composition of 3rd Division was as follows:

General Officer Commanding: Maj-Gen Bernard Montgomery

7th Brigade (Guards)
 * 1st Battalion, Grenadier Guards
 * 2nd Battalion, Grenadier Guards
 * 1st Battalion, Coldstream Guards
 * 7th Infantry Brigade (Guards) Anti-Tank Company

8th Infantry Brigade
 * 1st Battalion, Suffolk Regiment
 * 2nd Battalion, East Yorkshire Regiment
 * 2nd Battalion, Gloucestershire Regiment (until 5 February 1940)
 * 4th Battalion, Royal Berkshire Regiment (TA) (from 5 February 1940) (replaced by 1st Battalion South Lancashire Regiment after Dunkirk).
 * 8th Infantry Brigade Anti-Tank Company

9th Infantry Brigade
 * 2nd Battalion, Lincolnshire Regiment
 * 1st Battalion, King's Own Scottish Borderers
 * 2nd Battalion, Royal Ulster Rifles
 * 9th Infantry Brigade Anti-Tank Company

Divisional Troops
 * 15th/19th The King's Royal Hussars (until 31 March 1940)
 * 7th Field Regiment, Royal Artillery
 * 23rd Field Regiment, Royal Artillery (until 5 March 1940)
 * 33rd Field Regiment, Royal Artillery
 * 76th (Highland) Field Regiment, Royal Artillery (TA) (from 5 March 1940)
 * 20th Anti-Tank Regiment, Royal Artillery
 * 246th Field Company, Royal Engineers
 * 248th Field Company, Royal Engineers (until 2 November 1939)
 * 253rd Field Company, Royal Engineers
 * 17th Field Company, Royal Engineers (from 2 November 1939)
 * 15th Field Park Company, Royal Engineers
 * 3rd Division Signals, Royal Corps of Signals
 * 8th Battalion, Royal Northumberland Fusiliers (TA) – Motorcycle battalion
 * 2nd Battalion, Middlesex Regiment – Machine Gun battalion (CO: Lt-Col Brian Horrocks)

Composition 1940–44
For over a year after Dunkirk the composition of 3rd Division remained largely unchanged (except that the motorcycle battalion was converted into 3rd (Royal Northumberland Fusiliers) Reconnaissance Regiment). Then, in September 1941, 7th Brigade (Guards) was transferred to the Guards Armoured Division, and the following November 37th Infantry Brigade Group HQ joined 3rd Division and was renumbered 7th Brigade with the following composition:

7th Infantry Brigade
 * 2nd Battalion, South Wales Borderers
 * 2/6th Battalion, East Surrey Regiment
 * 6th Battalion, Royal Sussex Regiment
 * 7th Infantry Brigade Anti-Tank Company

The brigade anti-tank companies were disbanded during 1941 and 92nd (Loyals) Light Anti-Aircraft Regiment, Royal Artillery, joined the division in March 1942.

In June 1942, 3rd Division was reorganised as a 'Mixed' Division, with 33rd Tank Brigade replacing 7th Infantry Brigade:

33rd Tank Brigade
 * 43rd Royal Tank Regiment
 * 144th Regiment Royal Armoured Corps
 * 148th Regiment Royal Armoured Corps

By early 1943, the experiment with 'mixed' divisions was abandoned, and 3rd Division reverted to being an infantry formation, 33rd Tank Brigade being replaced by 185th Infantry Brigade from 79th Armoured Division:

185th Infantry Brigade
 * 2nd Battalion, Royal Warwickshire Regiment
 * 1st Battalion, Royal Norfolk Regiment
 * 2nd Battalion, King's Shropshire Light Infantry

Thus the division had attained the organisation with which it went into action on D-day.

D-Day
3rd Division was the first British formation to land at Sword Beach on D-Day. For the assault landing, 3rd Division was organised as a Division Group, with other formations temporarily under its command. These included 27th Armoured Brigade (Sherman DD amphibious tanks) and 22nd Dragoons (Sherman Crab flail tanks), 1st Special Service Brigade and 41 (Royal Marine) Commando, 5th Royal Marine Independent Armoured Support Battery (Centaur IV close support tanks), 77 and 79 Assault Squadrons of 5th Assault Regiment, Royal Engineers (Churchill AVREs), plus additional Royal Engineers, Royal Artillery and Royal Army Service Corps.

The division's own artillery were all self-propelled (field regiments: M7 Priest;   anti-tank regiment: M10 tank destroyer  ) and the SP field guns and RM Centaurs were able to fire from their landing craft during the run-in to the beach. In addition, 3rd Division had 101 Beach Sub-Area HQ and Nos 5 and 6 Beach Groups under command for the assault phase: these included additional engineers, transport, pioneers, medical services and vehicle recovery sections. 3rd Division's brigades were organised as brigade groups for the assault, with 8 Bde Group making the first landing, followed by 185 Bde Group and 9 Bde Group in succession during the morning and early afternoon.

After D-Day
After D-Day 3rd Infantry Division fought through the Battle of Normandy, the Netherlands and later the invasion of Germany. For the campaign in Normandy, the division was commanded by Major General Tom Rennie until 13 June 1944; Major General Lashmer Whistler, a highly popular commander, took command on 23 June 1944. During the campaign, the division won its first Victoria Cross of World War II, awarded posthumously to Corporal Sidney Bates of B Company, 1st Battalion, Royal Norfolk Regiment, part of the 185th Brigade, for incredible bravery. James Stokes of the 2nd Battalion, King's Shropshire Light Infantry, also of 185 Brigade, was another who was awarded the Victoria Cross.

During the often intense fighting from Sword Beach to Bremen, the Division suffered 2,586 killed.

Post Second World War
Postwar, the Division was reformed on 1 April 1951, in the Suez Canal Zone, under the command of Sir Hugh Stockwell. The division became part of Middle East Land Forces. It consisted of three recently reraised brigades, the 32nd Guards, the 19th Infantry, and the 39th Infantry. It served in the UK for many years; in 1968 it was part of the Army Strategic Command. It had elements of 5th, 19th, and 24th Brigades attached to it. It became an armoured division in the British Army of the Rhine based at Soest near the Möhne Dam in 1977. When its sub-units were Task Force Echo (TFE) and Task Force Foxtrot (TFF), these changed around 1980 to 6 Armoured Brigade and 33rd Armoured Brigade.

1993 to 2014
The division was re-raised in the mid-1990s after 3rd Armoured Division disbanded in BAOR. It provided the headquarters for Multi-National Division (South-West) in Bosnia-Herzegovina in 1995 / 1996 and again in 1998. For a time it comprised 1st Mech Bde, 5th Airborne Brigade, and 19th Mechanised Brigade.

On 1 September 1999 the Division was freed from its administrative and regional responsibilities and it became a deployable or "fly-away" division.

As 3rd (UK) Mechanised Division it was the only division at continual operational readiness in the United Kingdom (the other at operational readiness being 1st (UK) Armoured Division in Germany). It was based at Picton Barracks, Bulford Camp, in Wiltshire and reported to the Commander Land Forces at Andover.

Under the divisional command there were originally four ready brigades, then three. 4th arrived from Germany while 19th disbanded.
 * 1st Armoured Infantry Brigade
 * 4th Mechanized Brigade
 * 12th Armoured Infantry Brigade
 * 3rd Division Headquarters and Signal Regiment
 * 5 Regiment Army Air Corps (Lynx)
 * 36 Engineer Regiment, Royal Engineers
 * 3 Regiment, Royal Military Police
 * The Royal Wessex Yeomanry

Current structure
Under Army 2020, the division will continue to be based at Bulford, and command the Reaction Force.
