152nd Infantry Brigade was a formation of Britain's Territorial Force/Territorial Army that was part of 51st (Highland) Division in both World Wars.

The Volunteer Force of part-time military units formed in Great Britain after an invasion scare in 1859 had no higher organisation than the battalion until the Stanhope Memorandum of December 1888 proposed a comprehensive mobilisation scheme.

[14][15] Although the TF was intended as a home defence force and its members could not be compelled to serve outside the UK, units were invited to volunteer for overseas service and the majority did so.

[17]) Individual TF battalions began being sent to the Western Front to reinforce the British Expeditionary Force (BEF): the 1/4th Seaforths landed in France on 7 November, and the 1/4th Camerons on 23 February 1915.

[14] The following officers commanded 152nd (1st Highland) Brigade during the war:[14] The TF was reconstituted on 7 February 1920 and was reorganised as the Territorial Army (TA) the following year, with some units having merged.

[20] After the TA was mobilised on 1 September 1939 152 Brigade had the following composition:[21] The 51st (H) Division joined the British Expeditionary Force (BEF) in France, 152 Bde landing on 27 January 1940.

However, when the Phoney War ended with the German invasion of the Low Countries on 10 May, 51st (H) Division was detached and serving under French command on the Saar front.

Cut off from the rest of the BEF, which was evacuated from Dunkirk, it retreated to the coast where most of the division was forced to surrender at Saint-Valery-en-Caux on 12 June.
