1st Battalion Irish Guards


The 1st Battalion Irish Guards was a regular army unit based in the UK at the start of the war. As part of 24 Guards Brigade It formed part of the expedition to Norway in April 1940 before being evacuated back to the UK in May. It then remained in the UK until March 1943 when it departed for North Africa as part of 1st Infantry Division. The battalion saw heavy fighting from the end of March through to the Axis surrender in Tunisia May 1943.

After the conclusion of the Tunisian campaign 1st Infantry Division remained in Tunisia until early December 1943 when it moved to Italy. Here 1st Infantry Division was identified as the British component for the Anzio operation and 1st Battalion Irish Guards landed in the second wave on the 22nd January 1944. After suffering appreciable casualties while participating in an unsuccessful attempt to advance out of the bridgehead at the end of January the battalion then suffered further heavy losses in the defensive fighting that followed throughout February. 

The severe casualties suffered by all three battalions of 24 Guards Brigade resulted in it being replaced in 1st Infantry Division by 18th Infantry Brigade. The battalion was withdrawn from the line on 25th February 1944 but remained at Anzio until 7th March when it was transported to Naples.

The battalion was severely understrength and there were virtually no Irish Guards reinforcements available in Italy or North Africa. This resulted in the decision being made to return the battalion to the UK. It was replaced in 24 Guards Brigade by 3rd Battalion Coldstream Guards that was transferred from 201 Guards Brigade with 1st Battalion Irish Guards going in the opposite direction.

The battalion left Italy on 11th April 1944 with 201 Guards Brigade, arriving back in Liverpool on 22nd April. The battalion served in a training role for the rest of the war, providing reinforcements for the two Irish Guards battalions in the Guards Armoured Division who were fighting in north-west Europe.

When the battalion arrived in Italy in December 1943 it was organised as a standard British infantry battalion as per WE II/233/2. Its rifle companies were named No. 1, No.2, No.3 and No.4 ,

Due to heavy casualties at the end of January and early February at Anzio the battalion was re-structured with just two rifle companies (No.2 and No.3) in mid-February and remained in this state until it left the Anzio Bridgehead on 7th March 1944. 

As part of the reorganisation of the Guards units in Italy, it was decided to return 201 Guards Brigade to the UK. Due to the lack of Irish Guards reinforcements in Italy it was decided to replace 1 Irish Guards with 3 Coldstream Guards in 24 Infantry Brigade (Guards) and return the Irish Guards to the UK with 201 Guards Brigade.
