Third Army joined in the Allied Hundred Days Offensive on 21 August, without a preliminary bombardment, but with massive artillery support once the attack began. By the end of August 62nd Bde RGA was with XVII Corps, and stayed with it for the rest of the war. The corps' task on 2 September was to capture the southernmost part of the Drocourt-Quéant Switch Line (the "Wotan Stellung") where it joined the Hindenburg Line. Zero hour was 05.00, and at 06.00 the heavy guns including 62nd Bde switched from CB work to firing at the ground ahead of the advancing infantry between the D-Q and Hindenburg lines and on Quéant and other localities. The successful advance of 57th (2nd West Lancashire) Division through this ground cracked open the defences and allowed the flanking divisions to force their way through the Hindenburg Support Position and across the roads behind.
