One of the most notable episodes was at the Battle of Messines in 1917 where 455 tons of explosive placed in 21 tunnels that had taken more than a year to prepare created a huge explosion that killed an estimated 10,000 Germans.

A mine is a terrible thing to waste...

To this day, that 455-ton mine at Messines is still the largest loss of life in world history from a non-nuclear explosion. Ten thousand men wiped out in a few seconds from the explosion or being buried alive when their trenches and dugouts collapsed. Horrifying.
