Second World War
Disbanded after the war the brigade number was reactivated in the
Territorial Army (TA), the British Army's part-time reserve, as the 115th Infantry Brigade shortly before the start of the
Second World War, this time composed of three TA battalions of the
Royal Welch Fusiliers, the 8th, 9th and 10th. The brigade spent most of the war in the United Kingdom as part of the
38th (Welsh) Infantry Division. From 2 August 1944, it formed Force 135 which was planning the reoccupation of the
Channel Islands. In the event, the plan did not go ahead, and the brigade left Force 135 on 30 January 1945. On 12 February, it moved to
North West Europe where it remained until the end of the war, serving variously under the direct command of
VIII,
XII and
I Corps.[2]
