The 4th Infantry Division was a regular infantry division of the British Army with a very long history, seeing active service in the Peninsular War and Waterloo Campaign, the Crimean and Boer Wars and both World Wars. It was disbanded after the Second World War and reformed in the 1950s as an armoured formation before being disbanded and reformed again and finally disbanded on 1 January 2012.

Napoleonic Wars The 4th Division was originally formed in 1809 by Arthur Wellesley, 1st Duke of Wellington, as part of the Anglo-Portuguese Army, for service in the Peninsular War. It fought in the Battles of Talavera, Salamanca, Roncesvalles, Vitoria, the Pyrenees, Orthez, and Toulouse, and the siege of Badajoz.

Waterloo At the Battle of Waterloo it was tasked with holding Wellington's right flank and, with the exception of its 4th brigade, took no active part in the fighting, but did capture the town of Cambrai afterwards. The commanding general at this time was Charles Colville. In his novel Les Misérables Victor Hugo credits Colville with asking for the surrender of the Imperial Guard at Waterloo and receiving General Cambronne's reply of "Merde".

Second Boer War The Army Corps sent from Britain on the outbreak of the Second Boer War in 1899 comprised three divisions (six brigades) while the troops already in South Africa were intended to constitute a 4th Division of three brigades. However, the troops intended to form the 7th and 8th Brigades became caught up in the Siege of Ladysmith.Amery, Vol III, p. 152. (The 9th Brigade fought at the Battle of Modder River under Lord Methuen and later joined his 1st Division.Amery, Vol II, p. 323.Amery, Vol IV, Appendix to Chapters I-XIV, pp. 503–14.) It was only after the Relief of Ladysmith in March 1900 that the 4th Division under the command of Lieutenant-General the Hon Neville Lyttelton was formed from the garrison and joined the Natal Field Force. It was sometimes known as the 'Ladysmith Division'.Amery, Vol IV, p. 168.Amery, Vol IV, p. 437.

Order of Battle The division was constituted as follows:

7th Brigade Brigadier-General Walter Kitchener 1st Battalion, Devonshire Regiment 1st Battalion, Manchester Regiment 2nd Battalion, Gordon Highlanders 2nd Battalion, Rifle Brigade (Prince Consort's Own)

8th Brigade Major-General Francis Howard 1st Battalion, King's (Liverpool Regiment) 1st Battalion, Leicestershire Regiment 1st Battalion, Royal Inniskilling Fusiliers – not from the Ladysmith Garrison 1st Battalion, King's Royal Rifle Corps

Divisional troops 2nd Brigade-Division, Royal Field Artillery 21st, 42nd and 53rd Batteries 2 x Naval 12-pounder guns 23rd Company, Royal Engineers

Service The troops of 4th Division were still sickly after the Siege of Ladysmith, and it played little part in Sir Redvers Buller's operations to clear the Boers out of Natal in May and June. It was then left to defend Natal when Buller advanced into Transvaal in July. The division was not complete until 5 August when Walter Kitchener's 7th Brigade caught up. It marched out next day with Buller towards Balmoral to link up with Lord Roberts's Army. The division fought an engagement with the Boers on the way to Amersfoort on 7 August, then carried out a 10-day march via Ermelo, skirmishing every day, with the opposition increasing as the column advanced. On 22 August Walter Kitchener was detached with part of his brigade to clear some troublesome Kopjes on the flank, and next day section of 21st Battery, RFA, was heavily engaged with Boer guns. The division joined up with Roberts on 27 August, when 7th Brigade assaulted an entrenched position on the Berg-en-dal kopje.Amery, Vol IV, pp. 175–80.Amery, Vol IV, pp. 398–9.Amery, Vol IV, pp. 438–56.

The Battle of Bergendal was the last set-piece action of the war, but was followed by a long period of Guerrilla warfare. British forces were increasingly dispersed into ad hoc columns pursuing small Boer forces. Lyttelton's division was reduced to five-and-a-half battalions and a Mounted infantry detachment for Buller's advance to Lydenburg in September. On 5 September 7 Brigade's camp came under long range artillery fire, but Howard and the artillery cleared the Boers away. The column entered Lydenburg on 7 September, then attacked Paardeplaats next day, when Lyttelton with his four remaining battalions attacked the Boer right. Buller's column then marched into the rugged country of North East Transvaal through the 'Devil's Knuckles' and 'Hell's Gate' before returning to Lydenburg on 2 October, capturing a large Boer supply column on the way.Amery, Vol IV, pp. 460–8.

Roberts and Buller returned to the UK In early October and Lyttelton took over command of Buller's forces scattered in small garrisons guarding the Natal–Delagoa Bay Railway. The brigade and divisional organisation was abandoned for the rest of the war.Amery, Vol V, pp. 47–50.
