“When the Great War opened in the late summer of 1914 the 3rd (Reserve) Battalion was mobilized at Hamilton  as a training unit and sent to Nigg, Ross-shire , remaining here until 1918, when it proceeded to Invergordon (as part of the Cromarty Garrison) and the following year to Bridge of Allan. 

When the trouble in ireland became acute the 3rd Battalion moved to the Curragh, where in September of the same year the 1st Battalion was reformed.

During the four years that the war endured the Battalion sent overseas and to every theatre of the war the enormous number of 1174 officers and 57, 265 other ranks; these reinforcements were, of course, primarilyintended for the battalions of the Regiment, but many of these drafts, both officers and men, were on arrival overseas posted to other regiments”.
