Mustard gas was bad stuff. They would blast an area with mustard gas and then as it would settle into the trenches and bomb craters guys would have to climb out of these. That's when they would switch from mustard gas to fragmenting bombs and blast the holly bajesus out of you.

I just can’t believe how long it took them to figure out that sending thousands of boys to charge interlocking machine guns wasn’t an effective method to gain ground anymore.

Oh and to top it off in those days they thought shell shock was a figment of your imagination.
