At the outbreak of the First World War in August 1914, the regiment consisted of three battalions. With the commencement of hostilities the regiment raised a service battalion, the 4th Battalion, and a reserve battalion known as the 5th (Reserve) Battalion, which was used to carry out ceremonial duties in London and Windsor during the war. The 1st and 2nd Battalions of the regiment were the first to be sent to France, and took part in the early stages of the fighting during the period known as "Race to the Sea", during which time they were involved significantly at the First Battle of Ypres. In February 1915, a fifth Guards regiment was raised, known as the Welsh Guards. In recognition of the significant contribution Welshmen had made to the Grenadier Guards, the regiment transferred five officers and 634 other ranks to the newly formed unit. A short time later, permission was received for the formation of the Guards Division, the brainchild of Lord Kitchener, and on 18 August 1915, the division came into existence, consisting of three brigades, each with four battalions. Following this the four service battalions of the regiment fought in a number of significant battles including Loos, the Somme, Cambrai, Arras and the Hindenburg Line. Seven members of the regiment received the Victoria Cross during the war.
Following the Armistice with Germany in November 1918, the regiment returned to just three battalions which were used in a variety of roles, serving at home in the United Kingdom, as well as in France, Turkey and Egypt.
