A team of men are struggling to position a Howitzer. Most of them are holding a shattered wooden frame directly in front of it. It is unclear whether this structure is to be used to secure the gun into position, or whether the gun will be rolled across it. Widely used by both sides, big guns were an effective offensive weapon. Manoeuvring them across the rough and uneven terrain of the Front, however, was extremely problematic and time consuming. Although not mentioned in the caption, this photograph was taken on the British Western Front. Of all the big guns, Howitzers and other guns with a high trajectory were favoured by both sides. Due to the angle of fire, the shell could pass over intervening obstacles before dropping into position. It was particularly useful in trench warfare, allowing those firing to target unseen positions. [Original reads: 'Clearing the ground for a Howitzer position.'].
