Many of these locally raised battalions suffered heavy casualties during the Somme offensives of 1916. A notable example was the 11th (Service) Battalion (Accrington), East Lancashire Regiment, better known as the Accrington Pals. The Accrington Pals were ordered to attack Serre, the most northerly part of the main assault, on the opening day of the battle. The Accrington Pals were accompanied by Pals battalions drawn from Sheffield, Leeds, Barnsley, and Bradford. Of an estimated 700 Accrington Pals who took part in the attack, 235 were killed and 350 wounded within the space of twenty minutes. Despite repeated attempts, Serre was not taken until February 1917, at which time the German Army had evacuated to the Hindenburg Line.
