During an attack, despite heavy machine-gun fire, Currey rushed forward and killed the whole crew and captured the weapon. Later, in the afternoon, the 53rd encountered intense fire from a strong point. Currey crept around the flank of the position and opened fire with a Lewis gun before rushing the post, inflicting many casualties and dispersing the survivors. His courageous action enabled the battalion attack to proceed. At 3 am next morning he volunteered to warn an isolated company to withdraw. Moving out into No Man’s Land he stood up and called out to the company. This brought a hail of enemy fire down upon him. His respirator was punctured and he was gassed, but he succeeded in contacting the exposed company which then returned safely.
