How did trench warfare in World War 1 make it a peripheral war of attrition?
The method of fighting used involved the soldiers of one side to rush up and “Over The Top” the parapet and rush towards their enemy with bayonets drawn. After trying to avoid the hail of machine gun bullets, grenades, bursting shells and anything else that the opposing army could throw at them, the soldiers would then engage in hand to hand fighting in the enemy trench. As you can see, fighting this way was costly.
