In World War I, What was the name of the battle where England lost over half of its attack force in one attack?

by CannibalFruit

I'm not even quite sure if this happened, but in the back of my mind i feel as if i read this somewhere. When i think about it the number of over 50,000 men comes to mind. 50,000 men lost in a single attack on German front lines. Can you guy's help me out or am i just making this up in my head?

You probably mean the Battle of the Somme. It was the bloodiest single battle of the entire war, and on the first day of battle the British Fourth and Fifth Armies suffered 57,470 casualties along with 19,000 deaths.
