25th Division (United Kingdom)

The 25th Division was an infantry division of the British Army, raised as part of Lord Kitchener's Third New Army (K3) in September 1914, shortly after the outbreak of the Great War. It served on the Western Front for most of the war.

Unit history
The component units of the division were assembled around Salisbury and moved to Aldershot in May 1915 to complete their training. The division was formed by Major-General Francis Ventris and crossed to France from 25 to 30 September 1915 under the command of Major-General Beauchamp Doran. The division comprised the 74th, 75th and 76th Infantry Brigades but the 76th Brigade was posted away on 15 October 1915 and replaced by the 7th Infantry Brigade. In June 1916 Major-General Guy Bainbridge took command and the division went on to fight at the Battle of the Somme, at the Battle of Messines, at the Battle of Passchendaele, in the German spring offensive of March–April 1918 and at the Third Battle of the Aisne.

The 25th Division was unlucky during the 1918 German Spring Offensives, being attacked three times (sharing its misfortune with the 19th (Western) Division, the 21st Division and the 50th Northumbrian Division). It was on the northern flank defences during Operation Michael in March 1918 and was moved north to refit. There it lost more men in the Battle of the Lys in April. Moved south to another quiet area, it was attacked for a third time in the Third Battle of the Aisne.

After suffering severe casualties in June 1918, the division underwent a refit and reorganisation, receiving infantry from divisions then serving in Italy. The reformed division moving back to France in September 1918. The division played a major role in the final few weeks of the war its most noted success was the capture of the village of Beaurevoir on 5–6 October 1918. The war came to an end over a month later with the signing of the armistice of 11 November 1918. The division was demobilised by the end of March 1919, having suffered 48,300 casualties during the war.
