 As a result, the 2nd Battalion, 19th Infantry Regiment, a unit that could trace its lineage back to 1860, was reformed as the 19th Battalion, perpetuating both the lineage of its predecessor Citizens Forces units and that of its associated AIF unit.In 1927, the unit adopted the territorial designation of "The South Sydney Regiment".At the same time the motto "Fortiter et Fideliter" (Boldly and Faithfully) was authorised.
