The brigade was disbanded in 1919 after the war. Reformed in 1939 in the Territorial Army (TA) as the 54th Infantry Brigade, it was part of the 18th Infantry Division. The brigade spent the early years of World War II in the United Kingdom on home defence and training duties, anticipating a German invasion. With the rest of the division, the brigade was sent to Singapore, under the command of Brigadier Edward Backhouse, in 1942 and, after the Battle of Singapore against the Imperial Japanese Army, surrendered along with the rest of the Singapore garrison. They became prisoners of the Japanese for the next three years in harsh and degrading treatment.
