By the way, destroying 3 swordsmen with 3 djinns works fine; here, it might also depend a little on the hero's level.
And if I had found that path to go through the forest behind the djinns (because I knew it existed, but I couldn't figure out how to get there), the outcome would have been different. As it was, I spent a week building up an army to defeat the archers and capture the djinns.
Defeating the swordsmen is not a problem. The problem is to keep 2 djinns alive after the battle with them. :) Andrey44_44, try to solve this puzzle using the save game provided a few posts earlier in this thread.
The more you play, the more experienced you become, learning all the new details of the game.
