Victory without losing a man (or woman/machine/beast/bug/alien/what-have-you)?

Well I remember I had the exact opposite happen. It was 3000pt game my blood angels versus my mates eldar. Every model in the game was killed. EXCEPT for Dante who was the sole survivor from a turn six showdown. It was one bloody game

Hi

Hasn't happened to me, but have seen it happen. Someone was playing Lizards vs Vampire Counts - 2000pt game. VC went first.
VC General cast a spell - double 1. Miscast. He didn't have anything to prevent a miscast.
Roll for spell effect - double 1. Blam. There goes general.
Whole VC army at this point wants run away. Had to test leadership on every unit. Every single unit failed. Run awaaaaaaaaaayyyyyyyyyyyyyyy.

Game setup took about 300% longer than the actual game.

Well for one, The Vampire Counts don't take leadership like that for The General dying, They take a "Crumble" test they cant run away...

I seem to recall a story about an old edition orks army (or orcs) about a wyrdboy who, erm, caused a cascading failure to the rest of the army. In this instance, every ork/orc on the table had his head explode. On turn 1.

As for the VC table, replace "general" with 'ethereal' and VC with "Tau" and I've seen (and caused) that to happen on many occasions, and thanks to a psychic choir, a good portion of the army went poof.

With my 4th ed Dark Elves I pull quite a few victories with 0 to 5 casualities per game.

A hell of an army list back then.

[Scorpion_062]

In a 1000 point game with my Eldar verus Necrons, I defeated my opponent and only lost 2 Guardians and 1 Howling Banshee. Pretty close to no losses.

I am quite notorious for winning with minimal or no casualties in return for wiping out the enemy's entire army.

My WHFB High Elves and WoodElves have both managed it on several occasions. I once played a 2500pt game against Lizardmen with my HE and won with only a single casualty.

My 40K Space Marines have also done it a few times, the most iconic being my 5 man squad of Assault Marines rampaging through an entire Tau army. I lost only my Emperor's Champion and 2 Tactical Marines.
They also faced off against an Eldar army, with no anti tank support. In one of my cheesiest and unfair moves ever I took my Vindicator and my Predator with the AC, HBs and PSB. I put my Assault Marines behind them while a unit of 2 Landspeeders with HBs and my Rocket-armed tactical marines brought him into my guns. Once he reached the city streets infront of my tanks, he couldn't get around them. Shooting from the tanks alone was dropping whole squads a turn, not to mention to the buzz-saw-like status of my Assault marines...

Nearest i got was my GKs vs a mates IG. He was using Forge World rules for some BIG tanks he had so all he had in the way of troops was 2 platoons and an ogrin squad in a 1500pt game. I lost perhaps half a GK squad before my GKT teleported in front of the 2 platoons and ogrins on turn 2 and proceded to turn them into mush by the end of turn 3. At that point i simply said i would hide from the big scary tanks for the next 2 turns so he packed up and left .
It has happened to me tho and i even remember the list (cheesy store members list). I had only just started the hobby and it was a case of feinlding anything i could to make 1500pts. He had :-

Avatar
3 x wraithlords w/brightlance/starcannons
3 x wave serpents w/brightlance/starcannons
2 x striking scorpian squads kitted out
1 x howling banshee squad kitted out
1 x dark reaper squad kitted out
He got turn 1, Dark reapers shot the bejezes outa me and Wraithlords took out my tanks. I caused 2 wounds on his avatar.
Turn 2, 30 aspect warriors decended on me.....

Must point out this was 4th ed and the old eldar dex beil tan list which allowed aspects to be troops. He retired that army just befor 5th ed and it had only been defeted twice i think at 1500pts and never at 1000pts (cant remember the 1000pt variant).

I have seen it happen though not in a one on one battle it was a group of 6 of us playing. My friends father was playing gaurd and brought a baneblade which everyone else decided to avoid all we said at the start was most points on the table at the end wins didn't loose a man and as such one mainly because one of the other players killed off all my dark lance and the eldar bright lances got taken out by the baneblade marine armies were infantry based so there was a single lascannon in each which got killed quickly so everyone left the thing alone and the troops behind it. This all happened before apoc.
