In his famous poem about life and death on the Western Front, 'Anthem For Doomed Youth', Wilfred Owen writes about "the monstrous anger of the gun". This photograph reveals what Owen was trying to convey. With a gun crew of twelve men required to feed shells into this howitzer, the gun does look like some sort of mechanical monster. The dust-storm on the ground is probably caused by the sudden movement of the gun when in recoil after firing. The gunner on the howitzer's left platform, appears to be adjusting the gun's firing sights. The howitzer in this image is elevated at a steep angle so as to fire its shells at a trajectory far higher than the artillery fire in previous conflicts. Firing shells at such a high angle (more than 45 degrees) meant that the shells tended to drop on top of their targets rather than exploding into them straight-on from the front. Howitzers were therefore the perfect artillery weapon for trench warfare on the Western Front. [Original reads: 'OFFICIAL PHOTOGRAPH TAKEN ON THE BRITISH WESTERN FRONT.
