A team of uniformed men are building what looks to be a Nissen hut. Sections of corrugated iron, curved to form a roof, are being secured to a raised frame. The hut is in the early stages of construction and has been positioned in a dip, behind a high mound of earth. This would have offered protection from enemy fire. As soon as an army entered a newly captured area of the Front, a number of urgent tasks had to be performed. Of utmost importance was the creation of secure transport and communication links between the newly captured area and headquarters. This often meant the building of new roads, bridges and railways through the area, and the laying of telegraph wire and telephone cable. [Original reads: 'Building a hut on newly captured ground.'].
