The 4th Lancashire Artillery Volunteers, later renamed to the 4th West Lancashire Brigade, known as 'The Old 4th', was a part-time unit of the British Army's Royal Artillery founded in Liverpool in 1859. It served on the Western Front during World War I, one of its members winning the Victoria Cross at Cambrai. Between the world wars the unit pioneered mechanical traction methods. During World War II it formed three regiments that saw action at Dunkirk, in East Africa, on Crete, at Tobruk (where one of its regiments was captured), in Burma, and in the final campaigns in Italy and North West Europe. It continued in the post-war Territorial Army until 1973.
