Summarize "trench warfare" and "no man's land."

Trench warfare caused enormous numbers of casualties. At least initially in World War I, forces mounted attacks from the trenches, with bayonets fixed to their rifles, by climbing over the top edge into what was known as “no man’s land,” the area between opposing forces, usually in a single, straight line and under a barrage of gunfire.
