"Study for a Trench Mortar Firing at Evening (iwm Art 3910)" image: four British soldiers and an officer man a trench mortar position in a wood. Two of the men prepare the mortars, which lie in two lines on the floor of the post, as well as stacked in a position under the parapet to the left. One man stands and loads the mortar into the barrel of the weapon, whilst another kneels behind it and adjusts the trajectory. The officer looks through a pair of binoculars through the wood and across No Man's Land towards three explosions in the distance, assessing the range and accuracy. There is barbed wire in front of the position and the ground is undulating with the trees largely reduced to stumps as a result of artillery fire.
