You are SO correct.
In addition, many trenches were dug with the sole purpose of using the tactic of using a "false retreat" to cause the enemy to advance, only to be blown to bits. The only problem? It worked less than half the time--the stuff didn't always explode! There was a documentary film about a village that was nearly totaled many years later by the very thing you mention.
So lots of that stuff still there, waiting...
