Discussion about Heroes I.

I just can't seem to get over this Dragon Pass. And if a competing computer player were to eliminate the dragons on the first turn, and the player's heroes then eliminated the brave opponent and all 3 castles on the next turn, would that be considered a walkthrough? I've encountered such a bug, and it also occurs in the second game.
I figured that's exactly what happened, when I first looked at the result. I just didn't realize that 5 blue birds could defeat goblins, especially with good artifacts.
Please excuse me for asking, but reading about the first game is a great pleasure.
