The offensive was eventually halted and afterwards, in August, the Allies launched their Hundred Days offensive. The brigade was subsequently committed to the Allied advance through the Somme Valley, taking part in actions at Proyart, Bray and Clery. Shortly before the end of the war, due to heavy casualties amongst the AIF in 1918, the brigade's establishment was reduced to three infantry battalions as one—the 37th—was disbanded in September in order to reinforce the other battalions. This was due to widespread manpower shortages in the AIF as a result of the high number of casualties suffered during the Hundred Days Offensive.
