In the aftermath of the attack, Hughes' brigade took part in another attack, this time around Hill 60 in late August. After this, the brigade's regiments returned to defensive duties. Hughes' health subsequently deteriorated and on 20 September he was evacuated, suffering from typhoid. Command of the brigade then passed to Antill. In March 1916, Hughes embarked for Australia, due to ongoing health issues. Nevertheless, he was able to rejoin the AIF with the rank of brigadier general in July 1918, taking up an appointment with the Sea Transport Service. He retired in March 1920 with the rank of major general.
