2nd and 3rd Lines of the 5th King's Own Scottish Borderers
Formation of the 2/5th and 3/5th KOSB
As mentioned previously, the organisation of Territorial Force battalions was altered in September 1914 to take into account the different terms by which men had signed when volunteering for their local battalion:
- home service only, or
- home service and overseas if required
Soon after mobilisation, men of the 5th KOSB who had signed for home service only were given the opportunity to sign up for Imperial War Service, i.e., if required, they agreed to serve overseas in a theatre of war. A good number of men did sign the new terms, but others decided to keep to their original terms of enlistment. Consequently, the battalion had a mixture of both categories. As a result, the battalion was split into first and second line units and given the fractional designations, 1/5th and 2/5th Bns., KOSB. Initially, the second line battalion was for home service only, but later in the war most of these men did serve overseas.
By the summer of 1915 most Territorial Force battalions had formed a third line, i.e, 3/5th Bn., and these battalions were used for training and supplying drafts of men to both the first and second line battalions.
2/5th KOSB
The second line of the 5th (Dumfries and Galloway) Bn., King's Own Scottish Borderers was formed in September 1914 at Dumfries. In January 1915 the battalion was attached to the 194th Brigade of the 65th (2nd Lowland) Division, a wholly 2nd-Line Territorial Force Division.
