In March 1918, the brigade was in the Battle of Tel 'Asur, but shortly afterwards was warned that it was to move to France, where reinforcements were urgently required to stem the German spring offensive.

Here the dismounted Yeomanry underwent training for service on the Western Front, including gas defence.

On 18 October, while advancing towards Lille, 231st Brigade 'found the machine-gun defenders of Sainghin assisted by a field battery, and they resisted stoutly; although the village was cleared during the morning, it was dusk before the Germans were driven out of the wood beyond and across the la Marque, and all the bridges being destroyed they could not be followed'.

[15] During the night of 8/9 November, patrols from 231st Brigade probed the German defences of Tournai and worked their way down to the River Scheldt.

At 07.00 on 9 November, 10th King's Shropshire Light Infantry crossed by a footbridge laid by the engineers at the northern end of the town, and the rest of the brigade followed through this bridgehead.

This was composed of three Regular Army battalions that had been stationed on or been transported to Malta since the start of the Second World War and had served there during the siege.

After Generalfeldmarschall Erwin Rommel's defeat at the Second Battle of El Alamein, in late 1942, Malta lost some of its strategic significance and the 231st Independent Infantry Brigade, joined the British Eighth Army in North Africa, who were preparing for the Allied invasion of Sicily (Operation Husky).

After some hard fighting, including the 2nd Devons at Regalbuto amongst the foothills of Mount Etna, the Germans were driven from Sicily and the Allies prepared to invade Italy.

Despite the success of the relatively brief campaign, the brigade sustained almost 600 casualties, with the 1st Hampshires losing over 300 men, the 1st Dorsets 189 and the 2nd Devons 113.

The 231st Brigade's second assault landing was at Porto San Venere on 7 September 1943, when the Allies invaded Italy.

The Longues-sur-Mer gun battery (as seen in the film The Longest Day where the German officer looks out at the invasion fleet), surrendered on 7 June to the 231st Brigade.

They held Joe's Bridge in Lommel across the Escaut Canal at the start of XXX Corps, advance to Arnhem during Operation Market Garden and was then present during the Nederrijn campaign in North West Europe.
