The 1st Line units of the Lancashire Heavy Brigade, RGA, were placed in suspended animation when they were demobilised in 1919. After the TF was re-established after the war, the two batteries of the brigade were combined with the two prewar batteries of the Liverpool-based 4th West Lancashire (Howitzer) Brigade, Royal Field Artillery, to form the 4th West Lancashire Medium Brigade, RGA, consisting of one battery of 60-pdrs and three of 6-inch howitzers. A former officer of the 4th West Lancs was authorised to raise this unit on 21 May 1920 at his unit's drill hall at The Grange, Edge Lane, Liverpool. When the TF was reorganised as the Territorial Army (TA) the following year, the brigade was redesignated 59th (4th West Lancs) Medium Brigade, RGA (TA) (the former 4th West Lancs fought hard to get their 'Old Fourth' number included in the title). The brigade went on to win the prestigious King's Cup on two occasions in the 1930s, and spun off three medium regiments that fought with distinction at Dunkirk, Crete, East Africa, Tobruk and during World War II.
