 The battalions, like all other TF battalions, were redesignated with the '1/' prefix (1/4th Ox and Bucks, for example) to distinguish them from the 2nd Line units, formed of those men who did not originally volunteer to serve overseas, who were designated with the '2/', and were later numbered 184th (2/1st South Midland) Brigade, 61st (2nd South Midland) Division.The brigade was in continuous service in France on the Western Front in battles at Albert and in 1916 at Bazentin Ridge, Pozières Ridge, Ancre, all part of the Somme offensive.The 145th Brigade, with 48th Division, later pursued the German Army in the retreat to the Hindenburg Line and again fought in the Battle of Langemarck and later at Polygon Wood, both part of the Passchendaele and later on the Italian Front until the Armistice in 1918 with Germany.
