On 20 September 1917 the 2/6th Bn (codenamed 'UNBOLT') took part in 58th Division's successful attack at St Julien during the Battle of the Menin Road Ridge. Its task was to leap-frog through the 2/8th and 2/5th Bns making the initial attacks, and then turn right to attack the German lines in flank with the support of tanks. All the objectives were quickly taken, together with numerous prisoners, and with relatively few casualties mainly from the German defensive barrage. As the battalion consolidated its gains, messages sent by dog and carrier-pigeon brought down supporting artillery fire on any German troops seen attempting to form up for counter-attacks.
