I remember an interesting twist on "best laid plans going wrong". It happened many, many (
many many...) years ago, in my early days of wargaming with GHQ micros (when T-34/76b's came in a plastic hinge-top box with red foam), in a game I played a game against my Jr. High School gaming buddy -- well not really a buddy, just a gaming rival.
I had just gotten my first Soviet 76.2mm guns by mail-order from a UK vendor (GHQ didn't make any yet), and I was anxious to get them into action. So I invited him over for a 1943 battle on the Eastern Front. The scenario would be him attacking my interpretation of a pakfront. Per WRG rules, I set up a points total, and gave him 3x my points number to work with.
In those days we played in the dirt. We played in actual 1/300 scale (1 yard on the ground = 300 yards in the game). I had a sandy plot in my parent's yard, about 10 x 16 ft, that we used for smaller battles. His whole yard was undeveloped dirt, which we used for larger battles.
My pakfront was very simple. I put up an anti-tank ditch (actually dug out of the ground), with a gap in it which was marked as a minefield. Some 500yds behind it was a low rise, with my guns dug-in (actually dug in to the ground) camoflaged by some shrubbery (lichen).
I sent him a drawing of the battlefield, along with his points total, to use in preparing for the battle. It had been my initial intention to put down dragon's teeth rather than the AT ditch, and so that's what the drawing showed.
He kit-bashed some SdKfz251 "mine roller" halftracks to carry engineers. His actual intent was to use the engineers blow his way through the dragon's teeth with demo charges. The mine rollers were just a back-up. When he saw it was a ditch rather than dragon's teeth, he shifted to his back-up plan. He drove his mine-rollers across the marked minefield to clear several lanes. I made him roll for mines even though he was using mine rollers (he resisted this roll, but I insisted). When his dice showed a "hit" from the mines, I told him that, in spite of the roll, no mines had detonated beneath his rollers. He looked puzzled for a moment, and then said: "So it's a DUMMY minefield?". I nodded.
He then charged his whole panzerkiel across the dummy minefield, and on into my defensive zone. He led with his tigers on the point and his Pz IVs on the wings. His Pz IIIs and halftracks were behind the leading wedge. Beautiful formation. I then told him he had rolled into an
unmarked minefield that was behind the marked
dummy minefield. We resolved the mine attacks. All but one of his tigers, and several of his Pz IVs were killed.
He picked up his tanks and went home in a huff.
After a week of preparation, we played for about 3 turns. Not a very fun game at all. I never even got to fire a shot with my new 76.2mm guns.
